GENERAL DESCRIPTION
Congratulations on the purchase of your Yaesu amateur transceiver! Whether this is your first rig, or if Yaesu equipment is already the backbone of your sta­tion, rest assured that your transceiver will provide many hours of operating pleasure for years to come.
The MARK-V FT-1000MP is an elite-class HF trans­ceiver providing exceptional performance both on trans­mit and receive. The MARK-V FT-1000MP is designed for the most competitive operating situations, whether you primarily operate in contest, DX, or digital-mode environments.
Built on the foundation of the popular FT-1000MP transceiver, the MARK-V FT-1000MP provides up to 200 Watts of power output on SSB, CW, and FM (50 Watts AM carrier). Additionally, a Yaesu-exclusive “Class-A” SSB operating mode provides ultra-linear signal output, at a power output level of up to 75 Watts.
Also new on the MARK-V FT-1000MP is the IDBT (Interlocked Digital Bandwidth Tracking) System, which automatically aligns the bandwidth of the Enhanced Digital Signal Processing (EDSP) receiver passband to match the IF filter passband. This improves operat­ing efficiency by removing the extra step of making separate analog and DSP filter adjustments. This fea­ture can be enabled or disabled with the press of a button, for maximum flexibility.
And for exceptional protection from strong nearby incoming signals, the new, Yaesu-exclusive VRF (Vari- able RF Front-End Filter) serves as a high-performance Preselector-ideal for multi-operator contest environ­ments. This filter is manually tuned, allowing the op­erator to optimize sensitivity or signal rejection with the twist of a knob.
In addition to the contribution of the VRF Preselector, superb receiver performance is a result of direct lin­eage from the legendary FT-1000D and FT-1000MP. New technology Direct Digital Synthesizers (two 10-bit and three 8-bit) are used in the local oscillator (all driven by a single TCXO master oscillator), resulting in ex­tremely fine tuning resolution with thirteen selectable tuning steps down to 0.625 Hz. You may select either “Flat” or “Tuned” front end RF amplification (using four FETs in a double push-pull, constant-gain stage), IPO (Intercept Point Optimization) utilizing direct feed to the first mixer, and/or three levels of RF attenuation in 6­dB steps. The “Tuned” RF Preamplifier provides high gain and low noise figure on the higher frequency bands, with lower gain and greater selectivity on the low bands, where strong-signal performance is criti­cally important.
To battle QRM, the MARK-V FT-1000MP comes equipped with a formidable defense. Fine tailoring of the IF passband is made possible with individually-se­lected, cascaded 2nd- and 3rd-IF crystal filter banks. World-renowned Collins® mechanical 500-Hz CW fil­ters are available as options for the Sub Receiver 2nd IF, and main receiver 3rd IF strip. An IF notch filter and concentric IF Shift and Width controls are also pro­vided. The IF Width circuit allows continuously narrow­ing receiver passband by selectively moving either the upper or lower filter skirt just as much as needed to reduce QRM while still preserving the maximum us­able bandwidth. This extensive analog IF filtering pro­tects the EDSP circuits that follow it, ensuring un­matched performance during crowded band conditions.

GENERAL DESCRIPTION
Yaesu’s Enhanced Digital Signal Processing (EDSP) circuitry, pioneered in the FT-1000MP, provides a wide array of interference-rejection and signal­customization features. On receive, three different sig­nal “Contour” enhancements, in addition to narrow­bandwidth peaking filters for CW and Data modes, help dig out weak signals from the noise. Combined with the EDSP Auto-Notch and Noise Reduction circuits, the IF analog filters and EDSP response Contours are without peer in the Amateur Radio industry for signal enhancement. On transmit, the EDSP Microphone Equalizer allows matching of the transmitter’s audio response to your voice’s pattern, thereby maximizing useful power output in the SSB envelope.
Advanced features include Dual Receive, Direct Keyboard Frequency Entry and Band Change, RF Speech Processor, RF Monitor for Voice modes, CW Pitch control, CW Spot switch, Full CW QSK, adjust­able IF Noise Blanker, Synchronous Tuning for AM, and all-mode Squelch. And the Yaesu-exclusive Shuttle-Jog tuning ring provides a spring-loaded manual scanning tool, perfect for sweeping across a band as you take a quick look for activity.
Frequency setup is extraordinarily simple on the MARK-V FT-1000MP. Besides direct frequency entry for both the Main and Sub VFOs, separate keys are provided for band selection, and each band key ac­cesses two independent VFO frequency/mode/filter settings per band, so you can establish separate VFO settings for two different parts of each band. The Sub VFO has its own banks of VFOs for each band, and you may copy frequencies from the Main to the Sub VFO, or swap frequencies between the two, with a single button push. The two VFOs allow simultaneous reception and display of two different frequencies, even in different modes and with different IF bandwidths. Receiver audio can be completely or partially mixed, or monitored separately in each ear.
In addition, 99 scannable memories are provided, each of which stores its own mode and IF filter selec­tion, in addition to frequency, Clarifier offset, and scan­skip status. What’s more, five quick-recall (“QMB”) memories can instantly store operational settings at the push of a button.
The built-in automatic antenna tuner includes 39 memories of its own, automatically storing antenna matching settings for quick automatic recall later.
A unique feature of the MARK-V FT-1000MP is the rear panel’s “REMOTE” jack, a multi-featured port which allows a number of possible control functions. When connected to the optional FH-1 Keypad (or a home-made keypad), the REMOTE jack may be used as a control pad for the contest message keyer, or for memory/VFO control of the Main or Sub receiver.
Interfacing for digital modes is extremely simple with the MARK-V FT-1000MP, thanks to dedicated AFSK and FSK connection jacks on the rear panel. Optimi­zation of the filter passbands, EDSP settings, carrier insertion point, and display offset are all possible via the Menu programming system.
The Yaesu CAT system provides a direct link to the transceiver CPU for computer control and customization of tuning, scanning and other operating functions. The MARK-V FT-1000MP includes a built­in data level converter for direction connection to a personal computer serial port. Yaesu products are sup­ported by most all of the leading contest and DX log­ging programs, and the programming protocol is in­cluded in this manual, if you wish to write your own software!
Special options for the MARK-V FT-1000MP include the TCXO-6 Temperature Compensated Crystal Os­cillator module, and a wide selection of IF filters to complement the four already installed as standard. External options include the DVS-2 Digital Voice Re­corder; SP-8 External Loudspeaker with optional LL-7 Phone Patch module; YH-77STA Stereo Headset; FH- 1 Remote Control Keypad; and the MD-100A8X Desk­top Microphone. Rounding out your Yaesu station, the VL-1000 1 KW Linear Amplifier is specifically designed to match your MARK-V FT-1000MP, providing the con­venience of fully automatic band change along with 1000 Watts of clean power output.
For safe transportation of the MARK-V FT-1000MP, a supplied separate power, the FP-29, provides the 30 Volt and 13.8 Volt power required for 200-Watt opera­tion. The reduced weight inside the transceiver case provides a greater safety margin during the shipment your MARK-V FT-1000MP via a parcel service, or when checking it as baggage for a DX-pedition.
Advanced technology is only part of the MARK-V FT-1000MP story. Yaesu stands behind our products with a worldwide network of dealers and service cen­ters. We greatly appreciate your investment in the MARK-V FT-1000MP, and we look forward to helping you get the most out of your new transceiver.

SAFETY PRECAUTIONS
Before initiating the installation of your MARK-V FT-
1000MP transceiver, please take the time to review
the following safety guidelines.
POWER CONNECTIONS
We strongly recommend that AC power for your MARK-V FT-1000MP be provided only from the sup­plied FP-29 AC Power Supply, so as to ensure that the voltage and current requirements of the MARK-V FT- 1000MP are fully met.
If you do need to provide DC power to your MARK- V FT-1000MP, on an emergency basis, from a power source other than the FP-29, please be absolutely cer­tain to observe proper connections in your wiring. Note that other manufacturers may use the same type of DC power connector as does Yaesu, but the wiring con­figuration of the other manufacturer’s plug will almost certainly be different from that specified for your trans­ceiver. The correct wiring diagram is shown below.
Typically, the ground connection consists of one or more copper-clad steel rods, driven into the ground. If multiple ground rods are used, they should be posi­tioned in a “V” configuration, and bonded together at the apex of the “V” which is nearest the station loca­tion. Use a heavy, braided cable (such as the discarded shield from type RG-213 coaxial cable) and strong cable clamps to secure the braided cable(s) to the ground rods. Be sure to weatherproof the connections to ensure many years of reliable service. Use the same type of heavy, braided cable for the connections to the station ground bus (described below).
Inside the station, a common ground bus consist­ing of a copper pipe of at least 25 mm (1”) diameter should be used. An alternative station ground bus may consist of a wide copper plate (single-sided circuit board material is ideal) secured to the bottom of the operat­ing desk. Grounding connections from individual de­vices such as transceivers, power supplies, and data communications devices (TNCs, etc.) should be made directly to the ground bus using a heavy, braided cable.
Do not make ground connections from one electri­cal device to another, and thence to the ground bus. This so-called “Daisy-Chain” grounding technique may nullify any attempt at effective radio frequency ground­ing. See the drawing below for examples of proper grounding techniques.
GROUND CONNECTIONS
The MARK-V FT-1000MP HF transceiver, like any other HF communications apparatus, requires an ef­fective ground system for maximum electrical safety and best communications effectiveness. A good ground system can contribute to station efficiency in a number of ways:
r It can minimize the possibility of electrical shock to
the operator. r It can minimize RF currents flowing on the shield of
the coaxial cable and the chassis of the transceiver;
such currents may lead to radiation which can cause
interference to home entertainment devices or labo-
ratory test equipment. r It can minimize the possibility of erratic transceiver/
accessory operation caused by RF feedback and/
or improper current flow through logic devices.
Inspect the ground system – inside the station as well as outside – on a regular basis so as to ensure maximum performance and safety.
Besides following the above guidelines carefully, note that household or industrial gas lines must never be used in an attempt to establish an electrical ground. Cold water pipes may, in some instances, help in the grounding effort, but gas lines represent a significant explosion hazard, and must never be used.
An effective earth ground system make take sev­eral forms; for a more complete discussion, see an appropriate RF engineering text. The information be­low is intended only as a guideline.

SAFETY PRECAUTIONS
ELECTRICAL SHOCK PREVENTION
Be certain that all station wiring is properly insu-
lated so as to prevent short-circuits which could dam­age this transceiver and/or accessories connected to it. Be sure to protect power cables from damage due to abrasion by ensuring that they cannot be walked upon nor crushed under rolling chairs, etc. Never route power cables near sharp metallic edges which might cut through protective insulation.
Never spill liquids into this transceiver, and do not
drop sharp metallic objects into the transceiver enclo­sure. Electrical shock may result when you attempt to remove the object.
Unsupervised children should be kept away from
any electrical apparatus such as the MARK-V FT-
1000MP transceiver and its accessories.
ANTENNA P RECAUTIONS
Always install antennas such that they can never
come in contact with outdoor power lines in the event of a catastrophic antenna support or power line sup­port structure failure. An adequate safety margin is usually provided by separating power lines from the antenna and its support structure [1.5 times the height of the support] plus [the length of any antenna or guy wires attached to the support] plus [the height of the power line support pole].
Ground the antenna support structure adequately,
so as to dissipate energy absorbed during a lightning strike. Install appropriate lightning arrestors in the an­tenna lead-in and rotator cable (if used) according to the arrestor’s instructions.
In the event of an approaching electrical storm, dis-
connect all antenna lead-in, rotator control, and power cables completely from the station, but only if the storm is not immediately in your area. Do not allow disconnected cables to touch the case of your MARK- V FT-1000MP transceiver or accessories, as lightning can easily jump from the cable to the circuitry of your transceiver via the case, causing irreparable damage. If a lightning storm is in progress in your immediate area, do not attempt to disconnect the cables, as you could be killed instantly should lightning strike your antenna, tower, or a nearby power line.
If a vertical antenna is used, be certain that humans
and/or pets or farm animals are kept away both from the radiating element (to prevent electrical shock and RF exposure danger) and the ground system (in the event of an electrical storm). The buried radials of a ground-mounted vertical antenna can carry lethal volt­ages outward from the center of the antenna in the event of a direct lightning strike.
RF FIELD EXPOSURE ADVISORY &
ELECTROMAGNETIC COMPATIBILITY
This transceiver is capable of power output in ex­cess of 50 Watts, so customers in the United States may be required to demonstrate compliance with Fed­eral Communications Commission (FCC) regulations concerning maximum permissible exposure to radio frequency energy. Compliance is based on the actual power output used, feedline loss, antenna type and height, and other factors which can only be evaluated as a system. Information regarding these regulations may be available from your Dealer, your local radio club, from the FCC directly (press releases and other information can be found on the FCC’s site on the World Wide Web at <http://www.fcc.gov>), or from the Ameri­can Radio Relay League, Inc. (225 Main St., Newington CT 06111 or <http://www.arrl.org>).
Remember to re-evaluate your station’s compliance with these regulations during portable operations such as Field Day or special-event stations.
Regarding electromagnetic compatibility: if this transceiver is used with, or in the vicinity of, a com­puter or computer-driven accessories, you may need to experiment with grounding and/or Radio Frequency Interference (RFI) suppression devices (such as fer­rite cores) to minimize interference to your communi­cations caused by energy from the computer. Com­puter-generated RFI is usually a result of inadequate shielding of the computer’s cabinet or I/O and periph­eral connections. While computer equipment may “comply” with RF emission standards, this does not ensure that sensitive amateur radio receivers will not experience interference from the device!
Be certain to use only shielded cables for TNC-to­Transceiver connections. You may need to install AC line filters on the power cord(s) of the suspected equip­ment, and decoupling ferrite toroidal chokes may be required on interconnecting patch/data cables. As a last resort, you can try installing additional shielding within the computer’s case, using appropriate conductive mesh or conductive shielding tape. Especially check “RF holes” where plastic is used for cabinet front pan­els.
For further information, consult amateur radio ref­erence guides and publications relating to RFI suppres­sion techniques.

GENERAL SETUP
PRELIMINARY INSPECTION
Inspect the transceiver upon opening the packing carton. Check that all controls and switches work freely, and inspect the cabinet for any damage. Ensure the accessory fuses and plugs pictured on page 4 are in­cluded. If any damage is found, document it completely, and contact the shipping company (or dealer, if you purchased it over-the-counter) right away. Save the packing materials in case you need to return the set for service. If you have purchased optional internal accessories separately, install them as described on page 112.
POWER CONNECTIONS
The MARK-V FT-1000MP is designed to be used in conjunction with the supplied FP-29 Dual-Voltage Power Supply. Connect the Power Cable from the FP- 29 to the DC IN Jack on the rear panel of the trans­ceiver.
Note that other manufacturers may use the same type of DC power connections as does your MARK-V FT-1000MP transceiver, but the wiring configuration of the other manufacturer’s plug almost certainly will be different from that specified for your transceiver. Seri­ous damage can be caused if improper DC connec­tions are made.
TRANSCEIVER LOCATION
To assure long life of the components, a primary consideration in setting up the MARK-V FT-1000MP is providing for adequate ventilation around the cabi­net. The cooling system of the MARK-V FT-1000MP must be free to draw cool air in at the lower rear of the transceiver, and to expel warm air out of the upper rear panel. Do not place the transceiver on top of another heat-generating device such as a linear amplifier, and do not place equipment, books or papers on top of the transceiver. Also, provide a few centimeters of space on either side of the transceiver, if possible. Avoid heat­ing vents and window locations that could expose the transceiver to excessive direct sunlight, especially in hot climates.
GROUNDING
For protection from electrical shock, and to ensure proper performance, connect the GND terminal on the rear panel to a good earth ground, using a heavy braided cable of the shortest length possible. All other station equipment should be connected to the same grounding cable, as close together as practical. If you use a computer with or near the MARK-V FT-1000MP, you may need to experiment with ground wiring to sup­press computer noise in the receiver, and ground loops during transmission.

GENERAL SETUP
ANTENNA CONSIDERATIONS
The MARK-V FT-1000MP is designed for use with any antenna system providing a 50 resistive imped­ance at the desired operating frequency. While minor excursions from the 50 specification are of no con­sequence, the transceiver’s Automatic Antenna Tuner may not be able to reduce the impedance mismatch to an acceptable value if the Standing Wave Ratio (SWR) present at the Antenna jack is greater than 3:1. Among the undesirable consequences that high SWR may produce are:
r The transceiver’s power amplifier protection circuitry
will reduce power if the Automatic Antenna Tuner is
unsuccessful in reducing the SWR. r Even if the Automatic Antenna Tuner successfully
normalizes the impedance presented to the radio,
feedline losses will escalate rapidly with increasing
SWR at the higher operating frequencies, especially
28 MHz. r Although high SWR itself does not cause feedline
radiation, the sudden onset of high SWR may well
indicate a mechanical failure in a matching device,
leading to an electrical condition which may cause
excessive feedline radiation, which can cause in-
terference to nearby home-entertainment devices.
Every effort should, therefore, be made to ensure that the impedance of the antenna system utilized with the MARK-V FT-1000MP be as close as possible to the specified 50 value.

ADJUSTING THE FRONT FEET
The two front feet of the MARK-V FT-1000MP can be set in either of two positions. By turning the knurled ring around a (retracted) foot clockwise, the middle of the foot will extend about one centimeter. Turn the ring as far as it will go (about ¼-turn) to lock the extended foot in place. To retract an extended foot, turn the knurled ring counterclockwise ¼-turn while pressing on the center of the foot.
Any antenna to be used with the MARK-V FT- 1000MP must, ultimately, be fed with 50 Ω coaxial cable. Therefore, when using a “balanced” antenna such as a dipole, remember that a balun or other match­ing/balancing device must be used so as to ensure proper antenna performance.
The same precautions apply to any additional (re­ceive-only) antennas connected to the RX ANT jack; if your receive-only antennas do not have an impedance near 50 at the operating frequency, you may need to install an external antenna tuner to obtain optimum performance.
Use high-quality 50 coaxial cable for the lead-in to your MARK-V FT-1000MP transceiver. All efforts at providing an efficient antenna system will be wasted if poor quality, lossy coaxial cable is used. Losses in co­axial lines increase as the frequency increases, so a coaxial line with only 0.5 dB of loss at 7 MHz may have 2 dB of loss at 28 MHz. For reference, the chart in the next column shows approximate loss figures for typi­cally-available coaxial cables frequently used in ama­teur radio installations.

MEMORY BACKUP
The memory BACKUP switch on the rear panel is turned on at the factory, allowing VFO and memory data to be retained while power is off. Backup current is miniscule, so it is not necessary to turn the BACKUP switch off unless the transceiver is to be stored for an extended period.
After five or more years of operation the transceiver may fail to retain memories, at which time the lithium battery should be replaced. Contact your dealer for replacement of the battery; for instructions on how to do so yourself, see page 114.

LINEAR AMPLIFIER INTERFACING
The MARK-V FT-1000MP can be used with the optional Yaesu FL-7000 or VL-1000 Linear Amplifier, providing automatic band switching via digital band data output from the BAND DATA jack on the rear panel of the transceiver. Most other amplifiers can be adapted to operate with the MARK-V FT-1000MP; however, the main points to be concerned with are the switching re­quirements of the amplifier, and if QSK (full break-in) operation is desired. The linear amplifier Tx/Rx switch­ing capability of the MARK-V FT-1000MP is described in the table below.

ACCESSORY INSTALLATION
OPERATION WITH QSK AMPLIFIERS
Connect the RF output from the transceiver ANT jack (A or B) to the RF input jack of the linear. Connect the ALC output from the linear to the EXT ALC jack on the rear of the transceiver (see the “About ALC” dis­cussion below). After making the RF and Tx/Rx switch­ing connections described below, you may need to adjust the ALC output level of the linear so that it is not overdriven by the MARK-V FT-1000MP. Your linear’s manual should describe how to do this.
If using a VL-1000, connect the BAND DATA Cable (supplied with the VL-1000) from the transceiver BAND DATA jack to the amplifier BAND-DATA 1 jack; this will provide automatic band selection for the linear, as well as QSK Tx/Rx switching control. You may also con­nect a user-constructed control cable (refer to VL-1000 manual for details) from the transceiver REMOTE jack to the amplifier BAND-DATA 2 jack to provide auto­matic amplifier tune-up for the linear using the MARK- V FT-1000MP. Press the VL-1000’s front panel ATT switch to activate the 3 dB input RF power attenuator, to pad the 200 Watt (maximum) input power from the MARK-V FT-1000MP.
page 11MARK-V FT-1000MP Operating Manual
ACCESSORY INSTALLATION
LINEAR AMPLIFIER INTERFACING
If using an FL-7000, connect optional cable E-767 (P/N D4000019) from the transceiver BAND DATA jack to the amplifier ACC-2 jack. This provides automatic band selection for the linear, as well as QSK Tx/Rx switching control. Turn on the FL-7000 rear panel ATT switch to activate the 3 dB input RF power attenuator, to pad the 200 Watt input power from the MARK-V FT- 1000MP.
If using another manufacturer’s QSK linear, and if its switching circuitry consumes less than 150 mA of DC voltage below 40 V, you can connect the Tx/Rx switching line for the linear to pin 2 (“TX GND”) of the BAND DATA jack (use pin 3 for ground), and the linear’s exciter-enable output to pin 8 (“TX INHIBIT”) of the BAND DATA jack. This line must be switched to ground to enable transmission once the linear is ready for ex­citation from the MARK-V FT-1000MP. If your QSK lin­ear sinks more than 100 mA or uses more than 15 V for T/R relay switching, you will have to provide a suit­able external interface transistor, controlled by pin 2. Be certain to make provision for suitable reduction of the drive power from the MARK-V FT-1000MP, so as not to damage your amplifier.
OPERATION WITH NON-QSK AMPLIFIERS (FL-2100 SERIES OR OTHERS)
The TX GND jack on the transceiver rear panel is connected to an internal relay, for non-QSK T/R switch­ing of linear amplifiers that use AC switching voltage, or DC voltage greater than +15 V, negative DC voltage of any kind (such as the Heath® SB-220/SB-221 mod­els), or if they are required to sink more than 100 mA for T/R switching. A schematic diagram of the relay circuit is provided below. If not using your linear ampli­fier in a full break-in environment, the use of this relay for amplifier switching is highly recommended.
This relay comes disabled (rear-panel LIN set to “OFF”) to avoid the clicking sound when the transceiver is used alone or with a QSK linear. To enable the relay for non-QSK linears that exceed the above T/R switch­ing requirements, you will need to move the LIN switch, located in the hole near the center of the rear panel, to its right position (see the drawing). Use a thin, insu­lated, sharp object to move the switch. Then connect the center contact of the TX GND jack to the positive relay-control line to your linear, and the outer contact to the “common” line or the linear’s chassis ground. Refer to the diagram at the next page; in this example, a older non-QSK amplifier (FL-2100B) is shown.
With the relay now enabled, the MARK-V FT- 1000MP can support non-QSK linear T/R switching voltages up to 100 VAC @ 500 mA, or DC voltage up to 60 V @ 200 mA, or closed-circuit current up to 1 A with DC voltage up to 30 V.

Caution - Please Read!!
The MARK-V FT-1000MP is designed for use with the FL-7000/VL-1000 when QSK operation with a linear amplifier is desired. If you are using a differ­ent amplifier, do not attempt QSK operation with the linear if its switching circuitry requires that the MARK-V FT-1000MP’s relay be enabled. Using pins 2 and 8 of the BAND DATA jack for other amplifiers will not work unless the control line sig­nals are carefully matched, and damage may re­sult otherwise.
During linear operation, be sure to account for the MARK-V FT-1000MP’s maximum power capabil­ity of 200 Watts, and take care not to over-drive your linear amplifier.
Your transceiver’s warranty does not cover dam­age resulting from improper connections to this jack, so if you are not sure of the linear amplifier’s break-in capabilities or switching requirements, the safest approach is to enable the relay, use the TX GND jack (after setting the LIN switch to the “ON” position) and resort to non-QSK operation. This will help prevent possible damage to the amplifier or transceiver.
ABOUT ALC
The MARK-V FT-1000MP provides an external ALC jack on the rear panel (RCA-type jack) for input of Au- tomatic Level Control voltage from a linear amplifier.
ALC voltage is used to provide dynamic control of the output of the transceiver, so as not to provide more drive than is needed for full amplifier output. The ALC control voltage range is 0 to –4 V DC, with the voltage going more negative as the amplifier’s drive require­ments are approaching fulfillment.
The MARK-V FT-1000MP’s ALC system is very typi­cal of designs in the amateur radio industry, and con­sequently is compatible with many manufactured and home-built amplifiers. However, ALC voltage may be generated by an amplifier in a manner incompatible with efficient ALC operation in the MARK-V FT-1000MP, and it is important that you recognize the differences in amplifier ALC circuits before proceeding with ALC line connection.
r ALC circuits which detect Power Output from the
amplifier, and generate negative-going ALC control
voltage when maximum output power has been re-
alized, will generally work properly with the MARK-
V FT-1000MP.
The exact amount of ALC voltage fed to the MARK-
V FT-1000MP can usually be adjusted via a poten-
tiometer on the rear panel of the amplifier.
r ALC circuits which detect Amplifier Tube Grid Cur-
rent, and generate ALC voltage when excessive
grid current is present, may not work well with the
MARK-V FT-1000MP and other similar transceiv-
ers, as the ALC voltage may be generated because
of amplifier mis-tuning not related to an excessive-
drive condition. With amplifiers deriving their ALC
voltage in this manner, we recommend that you not
connect the ALC line, and rather let the amplifier’s
protection circuitry manage its ALC requirements
internally.

DIGITAL MODEM (TNC, WEATHERFAX, ETC.) INTERFACING
The MARK-V FT-1000MP offers special features for digital modes, such as a built-in digitally-synthesized AFSK generator for RTTY and AMTOR terminal units, IF bandwidth optimization and automatic display off­sets, and an 18-ms transmit-to-receive turn-around time.
Low-level Main Receiver audio output is provided from the rear-panel RTTY and PKT jacks, and is unaf­fected by front panel volume control settings. If you prefer to use Sub Receiver audio for TNC input, switch S3001 (located on the AF UNIT circuit board, inside the transceiver, between the DVS-2 and PKT connec­tors) can be moved from the MAIN to the SUB posi­tion.
ACCESSORY INSTALLATION
DIGITAL MODES WITH A TNC
OR COMPUTER SOUND CARD
The explosion of new digital modes of amateur com­munication means that you will want to make connec­tions to your TNC and/or computer as “standardized” as possible. Generally, this will mean that you will want to connect your transceiver in an “AFSK” environment. On the MARK-V FT-1000MP, the PACKET jack is the “AFSK” connection port, while the RTTY jack is an “FSK” connection port. In the AFSK mode, the TNC or computer generates the data signal as a set of audio tones, while the FSK mode uses a closure to ground (in the TNC or terminal unit) to cause the transceiver to generate the “mark” and “space” tones.
(

Audio level is 100 mV from both jacks. The RTTY level is fixed; however, PKT audio level can be adjusted by potentiometer VR3010. In many cases, it is easier to perform level adjustments at the TNC.

DIGITAL MODEM (TNC, WEATHERFAX, ETC.) INTERFACING
Construct a patch cable or cables to make the nec-
essary connections between your TNC and the appro­priate rear panel jack(s) (RTTY for FSK, PACKET for AFSK). Refer to the pin-out diagram below, and the wiring instructions included with your TNC. A descrip­tion of the PACKET jack’s individual pins follows:
Pin 1 (DATA IN) - Connect this pin to your TNC’s
“AFSK Out” or “Mic Audio” output line. The optimum input level is 30 mV rms, and the input impedance is 3 k. Your TNC’s audio output level potentiometer will allow you to set the level to the optimum value. This pin may be used either for 300 baud SSB-mode digital operation or for 1200-baud FM packet. The bandwidth and frequency response are not, however, suitable for 9600 baud operation.
Pin 2 (Ground) - Connect this to the shield(s) of
the cable(s) used for connections between the TNC and the MARK-V FT-1000MP.
Pin 3 (PTT) - Connect this pin to the PTT line from
the TNC. This pin, when grounded by the TNC, places the MARK-V FT-1000MP into the Transmit condition.
Pin 4 (DATA Out) - Connect this pin to your TNC’s
“RX Audio” input line. This is a constant-level (100 mV rms @ 600 ) audio output line which is not affected by the position of the front-panel AF GAIN control.
For FSK operation using the RTTY jack, the fol-
lowing are the pin connections required:
Pin 1 (SHIFT) - Connect this pin to your TNC or
terminal unit’s “FSK Key” port. Closing and opening of this line to ground causes mark/space keying.
Pin 2 (RX AF OUT) - Same as “DATA OUT” on
PACKET jack.
Pin 3 (PTT) - Same as “PTT” on PACKET jack. Pin 4 (GND) - Same as “GND” on PACKET jack.
For operation on PSK31, connect your computer's sound card to the PACKET jack (for “PKT” mode op­eration) or the MIC and EXT SP jacks (for “SSB” mode
operation). Also, use
the "User" mode (see page 110) for PSK31 operation.
For most operation, you will want to use the PS31­U (for PKT mode) or PS31-SU (for USB mode) op­tions under “East Set;” while BPSK operation is not sideband-sensitive, QPSK operation, by convention, utilizes USB-side injection.
The “User” mode is accessed, during operation, by pressing and holding in for ½ second the [PKT] mode switch.
menu selection 8-6 to configure
Pin 5 (BUSY) - This is a “Squelch Status” pin not
generally required for digital mode operation. This pin is held at +5V when the squelch is open, and is grounded when the receiver is muted by the squelch (“no-signal” condition).

CAUTION!!
The MARK-V FT-1000MP cooling system is de­signed to handle continuous duty transmission at 200 watts output. However, for continuous-duty digi­tal modes like RTTY, we recommend limiting your transmissions to 3 minutes or less, with at least 3 minutes receive in between transmissions. Place your hand on the transceiver occasionally to en­sure that it’s not getting too hot, and try to keep power output at 100 watts or less.
You can limit the maximum RF power output to 75 watts via programming, by recalling menu selection 4-0 and choosing reduced power output.

NOTE: COMPUTER-GENERATED RFI
When using a TNC connected to your transceiver, or even having a PC located in the shack, the possibil­ity exists that you may experience computer-generated RFI (Radio Frequency Interference).
The CPU in a personal computer operates with a crystal-controlled oscillator (clock) and timing circuits. Common clock frequencies include 8, 12, 16, 20 and 25 MHz. In addition, high-speed digital data switching uses square waves, which produce odd-order harmonic frequencies.
Computer-generated RFI may appear at seemingly random frequencies (usually right where a rare DX sta­tion is calling CQ!) throughout the range of your trans­ceiver, and may sound like constant ticking or buzzing that may change as you type or work within a program. Severe RFI may have S-meter indications as much greater than S-9, making copy of voice signals difficult and data signals virtually impossible.
Computer-generated RFI is usually a result of in­adequate shielding of the PC’s cabinet or I/O and pe­ripheral connections. While computer equipment may
comply with RF emission approval standards, this does not ensure that sensitive amateur radio receivers will not experience RFI from the device.
There are a few steps you can take to reduce or eliminate computer-generated RFI. The first step is to ensure that only shielded cables are used for TNC-to­transceiver connections, carefully check RF ground connections and re-orient your station equipment in relation to the computer. Try moving your PC and pe­ripherals slightly and see if it has any affect on the RFI, in some cases, this alone may be enough to correct the problem.
If not, several additional steps to try include install­ing AC line filters on the power cord(s) of the suspected equipment and inserting decoupling ferrite toroidal chokes on interconnecting patch/data cables and smaller ferrite beads on single wires.
As a last resort, you can try installing additional shielding within the PC case, using appropriate con­ductive mesh/screening or conductive tape. Especially check RF “holes” where plastic is used for cabinet front panels. For further information, consult amateur radio reference guides and publications relating to RFI sup­pression techniques.

AF OUT JACK
This is a 3.5 mm miniature stereo phone jack which provides constant-level (100 mV @ 600 ) for con­nection to a WeatherFax decoder, tape recorder, or other accessory. The audio output level is not affected by the setting of the front panel AF GAIN & SUB AF controls, so you can turn the volume down, if you like, without affecting the audio level being presented to your decoding device. The tip connection of this jack is Main receiver audio, while the ring connection is Sub receiver audio.
The connections to the AF OUT jack are at the same level as the connection to Pin 4 of the PACKET jack. However, the two output ports use independent output buffer amplifiers, so you can freely connect and dis­connect devices to/from these ports without concern over the impedances and levels.
PTT (PUSH TO TALK) JACK
This RCA jack is wired in parallel with the front panel’s MIC jack, providing a handy connection point for a footswitch for voice operation, allowing hands­free PTT operation.
PATCH JACK
For transmit audio input for SSTV (Slow-Scan Tele­vision) operation, you may connect the SSTV terminal’s TX AUDIO line to the PATCH jack. You will need to dis- connect the microphone, however, during transmission, as the PATCH jack is connected in a “Y” configuration along with the microphone input (from pin 8 of the MIC jack).

KEYING INTERFACE SUGGESTIONS
FEATURES
The MARK-V FT-1000MP includes a host of fea­tures for the CW operator, the functions of which will be detailed in the “Operation” section later. Besides the built-in Electronic Keyer, two key jacks are provided, one each on the front and rear panels, for convenient connection to keying devices.
Both KEY jacks on the MARK-V FT-1000MP utilize “positive” keying voltage. Key-up voltage is approxi­mately +5V DC, and key-down current is approximately
0.5 mA. When connecting a key or other device to the KEY jacks, use only a 3-pin (“stereo”) ¼” phone plug; a 2-pin plug will place a short between the ring and (grounded) shaft of the plug, resulting in a constant “key-down” condition in some circumstances.
CONFIGURATION SUGGESTIONS
1. For everyday operation using the internal electronic
memory keyer, connect your paddle to the front
panel KEY jack, and activate the front panel [KEY
switch. If you wish to keep the keyer paddle’s cable
out of the way, connect the plug, instead, to the rear
panel KEY jack.
2. If two operators are using the MARK-V FT-1000MP
simultaneously (for a contest, Field Day, etc.), a
second keyer paddle may be connected to the rear
panel KEY jack. With the front panel [KEYER
switch pressed in, both operators’ paddles will have
access to the internal keyer.
3. If two operators are using the MARK-V FT-1000MP
simultaneously, but both wish to use a straight key,
outboard electronic keyer, or computer-driven key-
ing cables, the key plugs may be inserted into the
front and rear panel KEY jacks; now turn the front
panel’s [KEYER] switch off.

ANTENNA CONNECTIONS
The MARK-V FT-1000MP’s three antenna connec­tors, plus innovative microprocessor-based memory and switching circuits, provide excellent flexibility in setting up your antenna connections.
Typical antenna configurations are shown below. Remember that Antenna A and Antenna B (which are “SO-239” or “M” connectors) may be used for trans­mission and reception, while the RX Antenna port (which is an “RCA” type connector) may only be used for reception.
NOTE REGARDING
LARGE RECEIVE ANTENNAS
Although surge suppression is provided on all an­tenna ports, you may wish to consider building a simple external circuit which will disconnect, on TX, any antenna connected to the RX ANT IN jack, particularly if you are using a very long wire an­tenna such as a Beverage. Very long antennas can build up very high RF and static voltages on them, and the circuit below may provide better protection for your receiver’s input circuitry.

You can just glance through it quickly now, but some of the descriptions will be more meaningful if you take the time to read them in detail now. If questions arise later while pro­ceeding through the operation chapter, you can return to this chapter with the set powered up for control knob clarification. Some controls and switches are disabled under certain conditions.

FRONT PANEL CONTROLS
1. POWER Button
This button turns the transceiver on and off.
2. MOX & VOX Buttons
[
MOX] may be used in place of a microphone PTT
switch or CW key to activate the transmitter, when de­pressed. It must be in the undepressed position for reception.
[
VOX] enables automatic voice-actuated transmit-
ter switching in the SSB, AM and FM modes, and “semi­break-in” keying in CW mode. The controls affecting VOX operation are located in the top access panel. Menu Selection 7-5 sets the receiver recovery time dur­ing semi-break-in CW operation.
3. AGC Selector Knob
Selects main receiver Automatic Gain Control de­cay time for most comfortable reception, or disables receiver AGC (off). Normally this switch is set to the “AUTO” position. Strong signals will cause distortion if this selector is set to “OFF.”
4. PHONES Jack
A ¼-inch and 3.5 mm, 3-contact jack accept either monaural or stereo headphones with 2- or 3-contact plugs. When a plug is inserted, the loudspeaker is dis­abled. With stereo headphones such as the optional YH-77STA, you can monitor both receiver channels at the same time during dual reception. In this case, the headphone HP controls (page 32) beneath the top ac­cess panel adjust the levels for mixed, separate, or monaural headphone operation.
5. KEY Jack
This ¼-inch, 3-contact jack accepts a CW key or keyer paddles (for the built-in electronic keyer), or out­put from an external electronic keyer. You cannot use a 2-contact plug in this jack (to do so produces a con­stant “key down” condition). Pinout is shown on page
4. Key up voltage is 5 V, and key down current is 0.5 mA. There is another jack with the same name, con­nected in parallel with this jack, on the rear panel.
6. MIC PROC Knob
The inner MIC control adjusts the microphone in­put level for (non-processed) SSB and AM transmis­sion.
The outer PROC control sets the compression (in­put) level of the transmitter RF speech processor in the SSB modes, when activated by the button with the same name.
7. MIC Jack
This 8-pin jack accepts input from the MH-31B8D Microphone. MIC connector pinout is shown on page
4. Proper microphone input impedance is 500 ~ 600 Ohms.

8. AF GAIN RF GAIN Knob
The inner AF GAIN control adjusts the audio vol­ume of the main receiver VFO in the speaker or head­phones.
The outer RF GAIN control adjusts the receiver sig­nal level in front of the main receiver 1st mixer (via PIN diodes), and also the gain of the main receiver IF am­plifiers.
It is normally set fully clockwise for maximum sen­sitivity. When rotated counter-clockwise, the S-meter minimum deflection point will move up the scale. The peak deflection for a particular signal will remain the same if it is greater than the level set by this control, but the main receiver will be less sensitive to weaker signals.
This control also affects the SQL setting for main VFO-A, and should be preset fully clockwise when set­ting the squelch threshold for the VFO or on a recalled memory.
9. RF PWR Knob
This control adjusts the transmitter’s output power in all modes. The adjustment range is from approxi­mately 5 to 200 watts, except in the AM mode, where the permitted carrier level is about 5 to 50 watts. This knob also controls the carrier level for CW transmis­sion. In setting the output power, the ALC function of the meter should always be monitored, to avoid overdriving the transmitter final amplifier.
13. MONI Knob
When activated by the [MONI] button (above), the audio level of the transmit RF monitor during transmis­sion (relative to the AF GAIN control) is adjusted by this control.
14. SQL Knob
This control sets the signal level threshold at which main VFO-A receiver audio is muted (and the green “MAIN BUSY” display indicator turns off), in all modes. This control is normally kept fully counter-clockwise, except when scanning and during FM operation.
15. METER Selector Switches
These switches determine the function of the mul­tifunction meter during transmission. The meanings of the abbreviations are as follows:
IC/SWR - Final amplifier collector current
(Amps) and Standing Wave Ratio (forward: reflected).
ALC/COMP - Relative Automatic Level Control volt-
age and RF speech compressor level (in dB, for SSB modes only).
VCC/MIC - Final amplifier collector voltage and
microphone gain input level.
The meter indicates power output and the selected parameter during transmission, and signal strength in S-units during reception (on the main receiver). Each S-unit is approximately 6 dB.
In the “Class A” SSB operating mode, the adjust­ment range for power output will be between approxi­mately 5 and 75 watts.
10. PROC Button
This button enables the RF speech processor for SSB transmission. Processing level is set by the outer control with the same name. While activated, the LED in this button glows red.
11. MONI Button
This orange button enables the transmit (RF) moni­tor in all modes (except CW, in which the monitor func­tion is always on, to produce the sidetone). While acti­vated, the LED in this button glows red.
12. SUB AF Knob
The SUB AF control adjusts the audio volume of the sub receiver VFO in the speaker or headphones.
The AF GAIN control, located above, and this SUB AF control can be rotated to adjust the relative bal­ance of receiver audio between the two receiver chan­nels during dual reception.
16. ATT Selector Knob
This knob inserts 6, 12, or 18 dB (1, 2, or 3 S-units) of attenuation before the mixer to suppress band noise and reduce the possibility of overload from very strong signals.
17. IPO Button
The Intercept Point Optimization button may be used to set optimum receiver front end characteristics for a strong environment. Selecting IPO bypasses the front end RF amplifier and feeds the received signals di­rectly to the first mixer.
18. ANT [A/B RX] Buttons
[
A/B] - Pressing this selects either the ANT A or B
jack on the rear panel, and allows conve­nient antenna switching at the press of a but­ton. The selected antenna jack is also indi­cated at the top of the display (above the channel group number).
[RX]
- Normally, the antenna connected to the ANT A or B jack is used for receive (and always used for transmitting). When this switch is pressed (display indicator on), an antenna connected to the RX ANT IN jack is used during receive.

23. MAIN VFO-A Tuning Knob
This large knob adjusts the operating frequency of Main VFO-A (or a recalled memory). Default tuning increments are 10 Hz (100 Hz in AM and FM modes). When the [FAST] button has been pressed, the incre­ments are 10x these sizes. See the table on page 38 for a listing of all available steps.
24. Shuttle Jog and VRF & IDBT Buttons
The Shuttle Jog ring allows fine or rapid frequency excursions with just a slight turn of your hand. Rotating the ring slightly either to the left or the right tunes down­ward or upward a few steps. The tuning rate increases the farther the ring is rotated.
Pressing the [VRF] button on the left side of the Shuttle Jog activates the VRF (Variable RF Front-end Filter), which adds a narrow input preselector filter into the RF receiver circuit on the 160-20 meter Amateur bands. Its passband can be tuned by rotating the VRF/ MEM CH knob, located on the upper right corner of the front panel, for maximum sensitivity and out-of-band interference rejection.
Pressing the [IDBT] button on the right side of the Shuttle Jog activates the IDBT (Interlocked Digital Bandwidth Tracking) System, which matches the EDSP (Bandwidth) filter characteristics to the settings of the SHIFT and WIDTH knobs. Thus, it is not necessary to re-adjust the EDSP settings if you change the (IF) WIDTH and/or SHIFT settings; the EDSP settings will automatically follow those of the higher-frequency IF passband.
25. LOCK Button
This button toggles locking of the main tuning knob to prevent accidental frequency changes. “LOCK” is displayed in a red box below and to the left of the main frequency display field when this command is active (the tuning knob can still be turned, but it does noth­ing). Press [LOCK] again to enable the tuning knob.
26. AF REV Button
Pressing this reverses the main/sub receiver audio adjusted using the AF GAIN knob and SUB AF knob. When activated, the LED inside this button glows red.
28. MAIN VFO-A [RX & TX Switch-LED
These combination lamp-switches select and indi­cate the transmit/receive status of the main tuning knob and display. When the green “RX” lamp is lit, the re- ceiving frequency is under control of the main knob and display (either VFO-A or a recalled memory chan­nel). When the red “TX” lamp is lit, the transmitting frequency is under control of the main knob and dis­play. Thus, for “normal” (non-split) operation, both the red and green lamps associated with the main tuning knob will be illuminated.
]
29. VFO/MEM Button
This button toggles main receiver operation between the memory channel and the main VFO-A. Either “VFO,” “MEM,” or “M TUNE” will be displayed to the left of the main frequency display field to indicate the current selection. If a displayed memory has been re­tuned, pressing this button returns the display to the original memory contents, and pressing it again returns operation to the Main VFO.
30. [MuA] Button
Pressing this button momentarily displays the con­tents of the currently-selected memory channel for three seconds. Holding this button for ½ second copies the data from the currently selected memory to the Main VFO-A, as two beeps sound. Previous data in the Main VFO will be overwritten.

Pressing and holding in this key for ½ second (until the double beep) copies the current operating data from Main VFO-A, or a recalled memory, to the currently selected memory channel, overwriting any previous data stored there. Also, pressing and holding this but­ton after recalling a memory, without first retuning, causes the memory channel to be “masked,” and re­peating the process restores the masked memory.
[
RPT] Button:
For 29 MHz FM operation, this button activates the standard HF FM repeater offset. Pressing [RPT] once or twice while receiving causes the transmit frequency to be shifted 100 kHz below or above the receiving frequency, respectively. A selectable CTCSS subaudible tone is also transmitted automatically when using this feature, to allow access to repeaters that require it. Pressing [RPT] a third time cancels repeater shift operation.
34. BAND (Keypad
The keypad provides one-touch band selection, or digital frequency entry. Normally, pressing one of the ten white numbered keys selects the corresponding (MHz) amateur band for operation (pressing the SUB button first, followed by a [BAND] key, selects that band for the Sub VFO). If you press the white numbered key for the band you are already on, you will select the alternate subband VFO on that band. See the “Opera- tion” chapter for details.

6. FM MIC
During FM operation, this control adjusts the mi­crophone gain (and transmitter deviation). More clock­wise settings produce a wider bandwidth signal.
NOTE: This control has been preset at the factory to produce the correct deviation with standard micro­phone levels. A deviation meter should be connected for proper readjustment, as it is difficult to determine the proper setting by ear. Remember that maximum deviation permitted on HF is ±2.5 kHz.
7. VOX
This control sets the gain of the VOX circuit, to set the level of microphone audio needed to activate the transmitter during voice operation while the VOX but­ton on the front panel is depressed.
8. DELAY (VOX Delay
This control sets the hang time of the VOX circuit, between the moment you stop speaking, and the auto­matic switch from transmit back to receive. Adjust this for smooth VOX so the receiver is only activated when you want to listen.
)
5. TUN-M
This control adjusts the tuning meter segment indi-
cations.
Do not adjust this control, by mistake, as this control will adversely affect meter tuning indica­tion, and requires factory re-alignment!.
9. A-VOX (ANTI-VOX TRIP
This control sets the level of negative feedback of receiver audio to the microphone, to prevent receiver audio from activating the transmitter (via the micro­phone) during VOX (voice-actuated transmit/receive switching) operation. Adjustment is described in the Operation chapter.

10. PKT
This control adjusts the tuning meter segment indi-
cations for Packet center tuning.
11. RTTY
This control adjusts the tuning meter segment indi-
cations for RTTY center tuning.
12. CW
This control adjusts the tuning meter segment indi­cations for CW center tuning. It should be adjusted such that the center segment lights up when your fa­vorite pitch (as set by the CW PITCH control and con- firmed by pressing the [SPOT] button) is received.
Additional Note
The volume of the beep that sounds when a front­panel button is pushed can be adjusted by turning a trimmer accessed via the small hole on the bot­tom cover of the transceiver. Insert a small, thin, insulated, flat screwdriver into the hole to adjust VR3001 for the desired beep volume. The Beep tone frequency is adjusted via menu selection 4-2; see page 101.

10. PTT Phono Jack
This input jack may be used to provide manual trans­mitter activation using a footswitch or other switching device. Its function is identical to the [MOX] button on the front panel. The same line is available at the PACKET and RTTY jacks for TNC control. Open-cir­cuit voltage is +13.5 VDC, and closed-circuit current is
1.5 mA.
11. EXT ALC Phono Jack
This input jack accepts negative-going external ALC (Automatic Level Control) voltage from a linear ampli­fier, to prevent over-excitation by the transceiver. Ac­ceptable input voltage range is 0 to –4 VDC.
12. PATCH Phono Jack
This input jack accepts transmitter audio - either AFSK or voice - for transmission. This line is mixed with the microphone audio input line, so the microphone should be disconnected if using this jack and mixing is not desired. Impedance is 500 ~ 600 Ohms.
13. EXT SPKR Mini Phone Jack
This 2-contact output jack provides mixed receiver audio for an external loudspeaker, such as the SP-8. Inserting a plug into this jack disables the internal loud­speaker. Impedance is 4 ~ 8 Ohms.
14. AF OUT Mini Phone Jack
This 3-contact jack provides dual-channel low-level receiver output, for recording or external amplification. Peak signal level is 100 mVrms at 600 Ohms. Main receiver audio is on the left channel (tip), and sub re­ceiver audio is on the right channel (ring). A stereo amplifier or recorder is recommended, to record each receiver’s audio separately when dual reception is en­abled. The front panel AF GAIN controls and the [AF
REV] switch setting in the top access panel do not af-
fect the signals at this jack.
15.GND Terminal Post
Use this terminal to connect the transceiver to a good earth ground, for safety and optimum perfor­mance. Use a large diameter, short braided cable.
16. BAND DATA DIN Jack
This 8-pin output jack provides control signals for the FL-7000/VL-1000 Solid-State Linear Amplifier, in­cluding band selection data to automatically set the Linear or Tuner to the same band as the main display of the transceiver. Band Data jack connections are shown on page 4.
17. +13.8V Phono Jack
This output jack provides regulated, separately fused 13.8 VDC at up to 200 mA, to power an external device such as a packet TNC. Make sure your device does not require more current (if it does, use a sepa­rate power source). Attempting to draw more power from here will blow the internal fuse behind this jack. Should this occur, replace the fuse (as explained on page 114).
18. RX ANT Phono Jacks (In/Out)
These antenna jacks are provided for connection for a separate receive-only antenna, activated when the switch with the same name on the front panel is pressed. An antenna connected here can be used by both the Main and Sub Receivers.
19. TRV Transverter Drive Output Jack
This jack provides a low level RF output for use with a transverter. Maximum output is approximately 100 mVrms at 50 Ohms (–6 dBm).
20.TX GND Jack (normally disabled)
When enabled by the [LIN] switch, this output jack connects inside the MARK-V FT-1000MP to a set of relay contacts which short together (to chassis ground) whenever the transmitter is active. This allows trans­mit/receive switching of an external device such as a linear amplifier. This jack is disabled at the factory, to avoid the clicking of the relay when it is not used.
Maximum ratings for these relay contacts are 500 mA @ 100 VAC, 200 mA @ 60 VDC or 1 A @ 30 VDC. Before connecting an external device, make sure its switching requirements will not exceed these limits. If your amplifier requires higher current, or has higher voltage switching requirements, an external switching device must be used.
21. LIN Linear Amplifier Relay Switch
To enable the TX GND jack when you are connect­ing a external linear amplifier, move this switch to its “ON” position.
22.DC IN Jack
Connect this 6-pin Molex socket to the Power Cable from the supplied FP-29 AC Power Supply. This socket provides +30V DC, +13.8V DC, and control signals for the MARK-V FT-1000MP.

RECEIVING
Note: the following procedure assumes the transceiver has not been used before, and not already set for Dual reception. If “DUAL” appears on the display when you switch on the set in the next step, you should press the blue [DUAL] button to return to the single-receiver mode
]
]
(for now).
Press the [POWER] switch on. The meter and dis­play should light up. If the display is too bright for your taste, it can be switched to a more subdued level using menu selection 3-4 (see page 100).
Take a moment to study the display. You should see “VFO” at the bottom, with the operating frequency of the Main VFO just above the main tuning knob. To the right of that is the Clarifier offset (“0.00”), followed by the memory channel number (“1-01” CH by default). At the right side of the display are the current mode and frequency of SUB VFO-B, which we’ll talk about later.
MENU PROGRAMMING
The MARK-V FT-1000MP incorporates a wealth of operating functions and features. For flexibility in con­figuring these capabilities, and to keep the front panel controls to a minimum, an internal Menu Programming routine is used. This allows customizing the functions via menu selections that previously required many elaborate DIP switch settings, power-on/button hold­ing routines, or additional front and rear panel controls/ switches. This permits each rig to have a custom “per­sonality” that specifically matches your operating re­quirements, with the capability for easy modification as your requirements change.
Menu programming is enabled by pressing the [
FAST] button, followed by [ENT]. You may then rotate
the VRF/MEM CH knob to display the desired setting. Each of the settings can be changed or customized, as you like, in this mode. For clarity’s sake, transceiver functions that have several settings or options are ref­erenced to the Menu Programming chapter separately, where details of programming are covered. Descrip­tions for most transceiver functions in this chapter as­sume default (factory-configured) transceiver settings.
There also are some “short-cuts” to certain Menu settings, and these will be described in the appropriate chapters to follow.
AMATEUR BAND SELECTION
Press a keypad key (between the two tuning knobs) to select a band for which your antenna is de­signed. Refer to the white “MHz” labels, and press the appropriate one.
Key Beeper
Pressing a front-panel button normally produces a beep. Its volume is independent of receiver vol­ume, and can be set by adjusting a trimmer via a hole on the bottom panel of the transceiver case.
To change the pitch of the beeper, recall menu sec- tion 4-2 (page 101) and select the desired pitch (between 220 and 7040 Hz) by turning the dial. You can also disable the beeper via menu selection 4-1 (also page 101).
page 36 MARK-V FT-1000MP Operating Manual
RECEIVING
MODE SELECTION
Press the [MODE] button (to the left of the main tuning knob) corresponding to the mode you wish to operate - for now, we sug­gest an SSB mode: USB if you have selected a band above 10 MHz, or LSB otherwise. The green LED in each button indicates the selected band, and a pair of LEDs within the bandwidth panel (to the left of the mode but­tons) indicate which IF filter pair is currently selected for that mode.
CW and RTTY have “reverse” modes that are selected by pressing their button twice (see the box at the right), and AM Synchronous tuning is activated in the same manner. Also, Packet operation can be toggled between LSB and FM (for 29 MHz operation) in the same way. These special fea­tures are covered later.
Additionally, notice that the bargraph meter format changes to the appropriate tuning display for the se­lected mode (covered later).
If you have selected an SSB mode, the red LED in the [NOR] button should be lit. If not, press [NOR] key. This bandwidth provides good fidelity for SSB recep­tion and should be used unless QRM from stations on adjacent frequencies becomes a problem (as described later).
Adjust the AF GAIN knob for comfortable volume on signals or noise in the loudspeaker or head­phones. The small SUB AF knob (to the under the AF GAIN knob) is used with the Sub VFO opera­tion and is explained in greater detail later.
OPERATION
Special Note for CW Mode
(Reverse CW sideband)
When you switch modes between CW and USB, you may notice that the frequency of received sig­nal stays the same (even though the panel fre­quency may change slightly). Also notice that the pitch of a received signal decreases as you in­crease the dial frequency.
However, switching to LSB from CW normally re­quires retuning the desired station. This can be es­pecially inconvenient if you enjoy working the lower HF bands (40 meters and below) where LSB mode is used.
To eliminate the need for retuning in this situation, you may switch the receiver CW carrier oscillator injection to the reverse side (LSB). When you press
[CW]
button, you should notice that the green LED in the USB mode button blinks for a second or two. This informs you of the default carrier offset (up­per) for CW. To switch to lower injection side, sim­ply press the [CW] button again; you will see the displayed frequency shift and the LSB LED will blink.
When using the reverse sideband (LSB) for CW reception, you can freely switch between LSB and CW without having to retune a station. Note that in LSB and CW modes the received signal pitch now increases as you increase the dial frequency.
To return the receiver to the default (upper) side­band, simply press [CW] again.
Operating Hint - An added benefit from this fea­ture is QRM rejection. If you have interference on a CW station that the IF SHIFT does not easily eliminate, you can try switching to the reverse side­band, retuning the signal, and trying the IF SHIFT again.

TUNING THE MARK-V FT-1000MP
Tuning is accomplished in several ways, with each
method having its own advantages; they are:
¦ Main & Sub VFO Knob Tuning ¦ Shuttle Jog Tuning ¦ Panel & Microphone Down/Up keys ¦ VFO Channel Stepping
VFO Knob
Rotating the Main VFO-A knob tunes the transceiver ac­cording to the se­lected tuning step size and encoder tuning rate. Both of these settings are configured via menu selections 1-3 & 1-4 (see page 99). The table below shows the available tuning step sizes and their default set­tings.

Shuttle Jog
The Shuttle Jog ring is more efficient for large fre­quency excursions, or whenever QSY requires spin­ning the VFO knob a lot, while still providing positive control with a comfortable feel.
Rotating the Shuttle Jog away from the center de­tent in either direction starts constant tun­ing. The farther the Shuttle Jog is moved from center, the larger the pro­gressive frequency steps (and QSY). There are 13 preset frequency steps incrementing through the arc of the Shuttle Jog (from 10 Hz ~ 100 kHz). The Shuttle Jog speed (encoder rate) is also configurable from 1 ~ 100 msec. via menu selection 1-1 on page 99.
Recall that the step size varies as the Shuttle Jog is turned, while the encoder rate is fixed. The effect of tuning faster as the Shuttle Jog is rotated actually comes from jumping to progressively larger tuning in­crements, as encoder rate remains constant.
For faster dial tuning rates with either the VFO knob or mic UP/DOWN buttons, press the [FAST] button below and to the left of the Main VFO knob (“FAST” appears). This selects the VFO speed, which can be switched between 4x (default) and 2x in menu selection 1-0 (see page 99). This affects the F per VFO knob rotation without changing the default tuning step size.

If your microphone has UP and DWN buttons, (such as the MH-31B8D) you can press them momentarily to tune in 10-Hz steps, or hold them to start VFO scan­ning. If it has a FST button, you can use it to duplicate the function of the [FAST] key on the transceiver front panel.
VFO Channel Stepping
This feature utilizes the VRF/MEM CH knob at the upper right corner, and
is unique because it allows “channellizing” the VFO for quick, yet precise, frequency navigation. For ex­ample, setting this feature to 1 kHz pro­vides an easy wasy of steping around an SSB band, looking for activity. Many bands such as AM broad­cast, HF maritime, aeronautical, and citizen’s band in­corporate assigned channels using discrete frequency steps. By configuring this feature for the service in in­terest, you can hop from one channel to the next with­out having to zero in (manually) each station’s signal with the VFO knob.
Display Settings
Display Mode - By default, switching to and from CW, PKT or RTTY modes causes the display to change by the amount of offset selected by the CW PITCH (page 56), RTTY, and PKT tone & offset configurations (pages 15 and 16). If you prefer the display to remain unchanged when switching modes, this can be done by setting menu selection 3-0 to BFO (carrier) display on page 100. However, the actual carrier offsets configured by the menu selections, relative to the display and IF bandpass are unaffected, regardless of the setting for menu selection 3-0.
Display Resolution - Although the MARK-V FT- 1000MP DDS (Direct Digital Synthesizer) tunes in
frequency increments as small as .625 Hz, display resolution is limited to 10 Hz. The 10 Hz and 100 Hz digits display can be turned off, as desired, if smaller frequency resolution is not needed (tuning steps are not affected).
Select the desired display resolution via menu se- lection 3-1 on page 100.
To enable operation using the VFO Step feature, it first must be enabled by press and holding the VRF/ MEM CH knob for ½ second.
Once enabled, rotating VRF/MEM CH knob as you would to tune a channelized FM rig. While VFO chan­nel stepping is enabled, “- - - -” appears in the channel number display, until the knob is pressed in again to disable channel stepping. Channel stepping is config­ured by menu selection 1-5 on page 99; also see Gen­eral Coverage Reception.
To disable the VFO Step feature, just press the VRF/
MEM CH knob momentarily.
VFO & Panel Locking Schemes
The locking scheme for the MAIN VFO-A [LOCK button offers three choices. By default, pressing the [LOCK] button so that “LOCK” appears only disables the tuning knob (it still turns, but does noth­ing). However, it can disable all front panel keys, or else all except the primary function keys. To se­lect the locking scheme, recall menu function 8-1, as shown on page 104.
Important! - Holding the [LOCK] button without releasing it activates the dual VFO tracking fea­ture, which is discussed later in the chapter.

ALTERNATE VFO OPERATION
(
“FRONT & REAR•EVFO
If you press the keypad band key for the same band
that you are already operating on, the display will shift to a different frequency in the same band (the bottom of the band by default). Pressing the same band key again switches you back to the frequency you were on before. What you have here are two completely inde­pendent VFO selections for each band, selectable by each band’s keypad key. You can think of the VFO for every band having a “front” and “rear” half that can be swapped for operation by toggling the band key. You can tune, select a mode and a bandwidth for each of these two VFO halves in each band, and they will be remembered until you return to this “sub receiver” se­lection.
)
Toggle VFOs
VFO SELECTION & RECEIVER M UTING
Above the Main and Sub VFO knobs are a pair of button/LEDs labeled RX and TX. The illuminated green “RX” LED indicates the VFO(s) controlling the receiver, while the red “TX” LED shows the VFO controlling the transmit frequency. As we will see later on in dual and split operation, these buttons can configure semi-du­plex operation as you choose.
You can mute the Main or Sub VFO at any time by pressing the RX button/LED above the corresponding VFO knob. The LED blinks while the receiver remains muted; simply press the button again to unmute.
KEYPAD FREQUENCY ENTRY
Frequencies can be entered directly, if desired, as follows:
Press [ENT] at the lower right corner of the keypad (the leftmost operating frequency digit will blink). Then, referring to the yellow numbers on the keypad, enter the digits of the new frequency, from left to right (1 - 4
- 2 - 5 - 0 - 0 - 0), followed by [ENT] again. As you enter the numbers, the next digit to be entered will blink on the display. You can use the DOWN buttons below the keypad to reposition the blinking digit location as desired (but ignore the direction labels on these buttons).
(q)
and UP
(p)
A practical use of this feature is to configure the front VFO for phone operation, and the rear half for CW operation on the same band (see the illustration above).
For example, if one of your VFOs is set to the SSB portion of the band (and in an SSB mode), press the keypad key for that same band, tune to the low end of the band, and press the [CW] mode button. You can consider this your CW VFO. Now press the band key again several times, and notice that operation toggles between the SSB and CW VFO halves. You can also select different IF bandwidths as well as modes for the two halves (and even different Clarifier settings). Note that this feature is not related to the MAIN VFO-A and SUB VFO-B scheme - dual receive and split operation will be covered later.
Only when you press [ENT] the second time will the operating frequency actually change, so if you de­cide to remain on the original frequency after starting to key in a new one, you can cancel any entered digits by pressing [SUB(CE)] (“Clear Entry,” the yellow label at the lower left corner of the keypad) instead of [ENT Note that, to enter frequencies below 10 MHz, you must key in the leading zeros.
That’s all there is to tuning Main VFO-A. Sub VFO­B has a lot more features of its own, which we’ll look at in detail later. First, however, let’s look at some other important receiver features.

RECEIVING
SIGNAL TUNING METER INDICATIONS
The MARK-V FT-1000MP incorporates several dis­play indications that make tuning stations a simple and accurate task:
Tuning Scale - When either CW, RTTY or PKT operation is selected, the tuning meter appears beneath the IC/SWR meter scale, as shown below.
In the CW mode, when you tune a signal near the center of the receiver passband, the boundary arrows light, and the upper signal strength segments increase as you slowly tune the VFO knob. The idea is to tune for maximum indication, and so that a lone center marker illuminates in the lower tuning meter (the bound­ary arrows turn off when the marker is centered). If you detune, the arrows illuminate, indicating that you need to re-center the marker.
OPERATION
For RTTY and Packet, dual segments appear (rep­resenting the mark and space tones), and in this case optimum tuning is achieved when even balance and maximum separation between the dual segments oc­cur. The minimum separation between the segments is proportional to the mark and space tone shift (170 Hz, 425 Hz or 850 Hz). We will cover more about RTTY and Packet operation later.
RTTY/PKT TUNING
CW TUNING
“Peak-Hold” Feature - During receive, the S-Meter segments respond instantaneously to the relative sig­nal strength (in S-Units) of stations. The meter “peak­hold” circuitry keeps the right-most bargraph segment on for a user-selectable time delay from 10 msec up to 2 seconds. The peak-hold feature is off by default, but you can enable it and select the desired delay time via menu function 3-7.
page 41MARK-V FT-1000MP Operating Manual
OPERATION
RECEIVING
EXPANDED TUNING SCALE
The bargraph segment meter above the MAIN VFO­A frequency display serves as a triple mode enhanced tuning scale. By default, it displays relative Clarifier off­set, and as you rotate the CLAR knob (either Rx or Tx Clarifier), the normally centered marker segment moves left or right, indicating the relative displaced (“clarified”) Rx or Tx frequency from the original. Be sure to see page 49 for more details on Clarifier op­eration.
When the VRF feature is engaged, the segments briefly indicate the peak position for the narrow band­pass “preselector” when you are turning the VRF/MEM CH knob. Be sure to see page 44 for more details on VRF operation.
AM SYNCHRONOUS TUNING
Audio distortion of AM stations due to carrier fading is common. Synchronous tuning reduces this phenom­enon by receiving the station in “LSB” while re-inject- ing an unfading carrier. The benefit of this technique is that the re-injected carrier is phase-locked to carrier of the original station, reducing the effects of fading and improving signal fidelity over that of conventional AM detection.
To activate AM synchronous detection, press the [AM]
button twice (so the green LED inside the button blinks). The tuning meter format changes to that be­low. Slowly tune across the signal until the lone center segment appears (see below).
AM SYNCHRONOUS TUNING
Alternately, you can have the segments expand outwardly as you tune either direction from the nearest displayed frequency. This lets you view tuning incre­ments smaller than 10 Hz (the maximum display reso­lution).
The rate and distance of segment displacement in either mode are proportional to the selected tuning step size and depend on whether or not the [FAST] button is engaged. The tuning meter mode is selected by menu selection 3-2.
SUB-DISPLAY MODE SELECTION
The small window to the right of the main frequency display can contain several different readouts, selected by menu selection 3-5.
These include:
Clarifire - Displays “clari­fied” frequency as offset from the original frequency.
Channel Freq. - Displays the operating frequency con­tained in the current memory channel providing “What if?” information while you are operating on a VFO.
Offset - Displays the fre­quency difference between the Main VFO and Sub VFO fre­quencies.
A1 (CW) Pitch - Displays the current CW pitch setting.
Whichever selection you choose, if you activate the Clarifier during operation, its display will over-ride any other (non-Clarifier) settings you may have set via menu selection 3-5.

RECEIVING
GENERAL COVERAGE RECEPTION
You may have already noticed that if you tune out­side one of the amateur bands (actually, outside of the 500-kHz segment that includes each band), “GEN” appears in a box at the left side of the display. On such frequencies, the transmitter and antenna tuner are dis­abled. If you try to transmit, “TRANSMIT” will blink. This confirms that transmission has been inhibited by the microprocessor.
Also, such frequencies are ignored by the band selection keys, so if you tune a VFO to a frequency outside of a ham band, you will have to store it in a memory (as described on page 64) if you want to be able to recall it quickly later. Otherwise, as soon as you press a band key, the general coverage frequency will be lost as the VFO reverts to the (ham-band) frequency it was on when the band was last changed.
Once you become familiar with the memories, you will find this really doesn’t present a problem, as each memory can be tuned just like a VFO, and stored into another channel without having to go through a VFO.
Aside from the above, general coverage reception provides all of the features available on ham frequen­cies, including dual channel reception, digital modes, and diversity reception, described on the following pages. A wealth of interesting broadcasts can be found outside the amateur bands, including:

In many countries, broadcast stations in the Stan­dard AM Broadcast Band are separated by a spac­ing of 9 kHz. The VFO Channel mode of operation can be highly useful in this case, as you can set the VFO channel step size to 9 kHz. Use the Main VFO-A knob to set a starting frequency, then press and hold in the VRF/MEM CH knob for ½ second.
If “9 kHz” has been set via menu selection 1-5, you can now use the VRF/MEM CH knob to tune through the broadcast band in the desired 9 kHz steps.

OPERATION
DEALING WITH INTERFERENCE
The MARK-V FT-1000MP includes a wide range of
special features to suppress the many types of inter­ference that may be encountered on the HF bands. However, real world interference conditions are con­stantly changing, so optimum setting of the controls is somewhat of an art, requiring familiarity with the types of interference and the subtle effects of some of the controls. Therefore, the following information is pro­vided as general guidelines for typical situations, and a starting point for your own experimentation.
The MARK-V FT-1000MP’s interference-fighting
circuitry begins in its “RF” stages, and continues throughout the entire receiver section.
VRF (VARIABLE RF FRONT-END FILTER
The VRF feature allows you to engage a narrow
band-pass “preselector” filter into the receiver’s RF cir­cuit path. The added selectivity can be a tremendous help in minimizing potential interference from strong out-of-band signals, especially in a multi-transmitter operating environment.
To activate the VRF feature, press
the [VRF] button on the Shuttle Jog, then turn the VRF/MEM CH knob to peak the signal or background noise level. When the VRF feature is en­gaged, the red “VRF” LED, located on the left side of the VRF/MEM CH knob, will be illumi­nated.
If a potentially-interfering signal is very near your cur-
rent operating frequency (for example, an SSB station operating near 3.80 MHz while you are on 3.52 MHz), additional protection may be realized by deliberately mis­tuning the VRF so as to place more “roll-off” of the undesired signal. In this example, tuning the VRF for peak response at 3.40 MHz will cause additional at­tenuation to be placed on the strong signal at 3.80 MHz. Particularly on the lower frequency bands, there will be no loss of useful sensitivity with moderate de-tuning, but interference rejection will be significantly enhanced.
)
FRONT END SELECTIONS:
AMP SELECTION, IPO & ATT
The best receiver front-end selection will depend on background noise at the time, the presence or ab­sence of strong signals, and whether or not you want to hear very weak signals. If the front end is set for too much gain, background noise will make listening diffi­cult, and very strong signals on other frequencies may cause intermodulation interference, masking weaker signals. On the other hand, if the front end is set for too little gain (or too much attenuation), very weak sig­nals will not be heard.
When evaluating the selections below, remember that if you can hear band noise increase when your antenna is connected, you have adequate sensitivity; any further early-stage gain is not needed.
“Wide Band” and “Tuned” Preamp Selection
Three high-performance FET RF amplifiers are uti­lized in the MARK-V FT-1000MP receiver front end. A single wide-band amp is provided for good general all­around performance, along with dual tuned amplifiers: one optimized for 24~30 MHz, the other for 1.8~7 MHz (see illustration). The Tuned preamp is especially use­ful when operating from a quiet location on 10 meters, while on the low bands the Tuned preamp’s low gain provides optimum strong-signal performance. Each amplifier is selected automatically as you tune or change bands; however, you can disable the tuned amplifier pair and only use the wide-band amp via menu selection 8-4.
Note that the Tuned preamp only operates in the
1.8~7 and 24~30 amateur bands. If you tune outside of an amateur band while using the Tuned preamp, the transceiver will automatically switch over to the “Flat” (Wide-band) preamp. The effects of this design are:
(1)When tuning outside of a low-frequency amateur

DEALING WITH INTERFERENCE
band (for example, tuning from 1.999.99 MHz to
2.000.00 MHz), the higher gain of the “Flat” preamp will cause the background noise to increase sud­denly (and decrease again if you tune back inside the 160-meter band).
(2) When tuning outside of a high-frequency amateur
band (for example, tuning from 28.000.00 MHz to
27.999.99 MHz), the higher gain of the Tuned premap will cause the background noise to de­crease suddenly (and increase again if you tune back inside the 10-meter band).
(3) When operating on the 14 MHz band, the Tuned
and Flat preamps have basically identical gains. Very little difference in performance will be observed, inside or outside the 20-meter band.
IPO (Intercept Point Optimization)
Normally, the front-end FET RF amplifiers provide maximum sensitivity for weak signals. During typical conditions on lower frequencies (such as strong overloading from signals on adjacent frequencies), the RF amplifiers can be bypassed by pressing the [IPO button so the green LED is on. This improves the dy­namic range and IMD (intermodulation distortion) char­acteristics of the receiver, at a slight reduction of sen­sitivity. On frequencies below about 10 MHz, you gen­erally will want to keep the [IPO] button engaged, as the preamplifiers are usually not needed at these fre­quencies.
ATT (RF Attenuator)
Even with the IPO function on, ex­tremely strong local signals can still de­grade reception. So if you still notice the effects of overloading, or if the signals you want to listen to are very strong, you can use the ATT selector to insert 6, 12, or 18-dB of RF attenuation in front of the RF amplifier. If background noise causes the S-meter to deflect on clear channels, turn the ATT selector clockwise until the S-meter drops to about S-1 (the white area at the left end of the top meter scale). This setting optimizes the trade-off be­tween sensitivity and interference immunity. Also, once you have tuned in a station you want to work, you may want to reduce sensitivity further (or add more attenu­ation) by turning the ATT control to a more clockwise setting. This reduces the strength of all signals (and noise) and can make reception more comfortable, im­portant especially during long QSOs.
When looking for weak signals on a quiet band you will want maximum sensitivity, so the IPO should be disabled and the ATT selector should be set to “0.” This situation is typical during quiet times on frequen­cies above 21 MHz, and when using a small or nega­tive-gain receiving antenna on other bands.
OPERATION
AGC (AUTOMATIC GAIN CONTROL) SELECTION
When tuning around the band look­ing for signals, the AGC selector is usu­ally best kept in the “AUTO” position, where AGC decay is automatically se­lected according to the operating mode. You can manually select re­ceiver AGC; however, a few points about AGC and re­ceiver recovery time need to be pointed out.
For SSB reception, the “FAST” position allows the receiver gain to recover quickly after tuning past strong signals or when fast fading occurs. However, once you have a station tuned in, reception will usually be more comfortable if you switch to the “SLOW” position (keep­ing the receiver from picking up low-level noise during pauses in speech).
For CW reception, when several signals are present in the passband, the “FAST” position can avoid AGC “pumping” (gain fluctuations) caused by strong
]
undesired signals.
For AM reception, the “SLOW” position is usually better, and for 300-baud packet and RTTY/AMTOR, the “FAST” or “OFF” positions will usually give the few­est errors/retries.
RF GAIN SETTING
When tuned to a moderate strength signal, if low level background noise is still present after setting the ATT selector, try reducing the RF GAIN control from the fully clockwise position. This reduces the signal input to the first mixer via a PIN diode attenuator and causes the minimum S-meter reading to move up he scale, often clearing up the background noise and put­ting the desired signal more “in the clear.” Remember, however, to return this control fully clockwise when you want to receive weak signals, or read low levels on the S-meter. Also read the box on this page.
Note on AGC
The AGC “OFF” position disables the overload-pro­tection normally provided by the AGC circuitry. If the RF GAIN control is left fully clockwise in this condition, the RF and IF amplifiers can be easily overloaded (causing distortion) when a strong sig­nal is received. Correct the overload either by set­ting the AGC selector to another position, or by turning the RF GAIN control counterclockwise to set receiver gain to a comfortable level.

NOISE BLANKER
Press the [NB] button to activate the IF Noise
Blanker.
The two noise blanker circuits in the MARK- V FT-1000MP are provided for two different types of pulse noise; (A) a narrow-pulse blanker for short pulse noise such as from switching transients, automobile ignitions, and power lines, and (B) a wide pulse blanker for longer duration man-made pulse noise. This noise blanker can sometimes also reduce the level of static crashes from electrical storms You can select the de­sired noise blanker circuit (“narrow” or “wide”) and its blanking level via menu selection 2-8.
In urban environments, there may be several or even dozens of local noise sources; these may com­bine in such a way as to make detection of a clear “impulse” impossible. The IF noise blanker may, how­ever, reduce the noise level significantly, allowing the EDSP Noise Reduction feature to reduce the noise even further.
If the blanker seems to distort a signal you’re lis­tening to, reduce the setting for optimum readability, or turn it off. During periods of extreme signal density (such as a contest), the noise blanker is best left off.
IF FILTER (BANDWIDTH) SELECTION
There are two banks of select­able filters, one each for both the
8.215 MHz 2nd IF and 455 kHz 3rd IF in the Main Receiver. Filter selections can be cascaded for versatility in combat­ting QRM and tailoring received audio. From the fac­tory, 2nd IF 500 Hz and 2.4 kHz filters and 3rd IF 2.4 kHz filter are provided. Other filters can be ordered from your Yaesu dealer. Installation instructions are cov­ered on page 113 and filter menu selections (5-0 through 5-7) on pages 101 and 102. The illustration at the bot­tom of the page provides a representation of filter se­lection in the MARK-V FT-1000MP.
Select the desired bandwidth by pressing one of the [BANDWIDTH] buttons. The LEDs inside each but­ton glow red while selected.
In the AM mode, the [NOR] (6-kHz) AM-wide band­width is typically selected for both the 2nd & 3rd IF (labeled THRU on the bottom of the 2nd IF column). This gives the highest fidelity, and is best on strong AM signals (and particularly music). The effects of the SHIFT and WIDTH controls in this wide bandwidth are subtle, but they can be helpful in fine tuning the audio characteristics. For weaker AM signals, or where adja­cent channel interference is present, the [NAR 1] (2.4 kHz bandwidth) offers a compromise between inter­ference rejection and fidelity. In this case, the SHIFT and WIDTH controls can be used quite effectively to improve fidelity (see the illustrations).
However, even better reception of AM signals un­der difficult conditions can usually be had by switching to an SSB mode (whichever gives the clearest recep­tion), and superb reception of weak signals is often possible using diversity reception, described on page
46.
In SSB modes, the [NAR 2] (2.0 kHz bandwidth) button can sharply cut interference from unwanted sig­nals on either side of the desired signal (although with some necessary loss of fidelity). In CW, the [NOR] (2.0 kHz or 2.4 kHz bandwidth) is often convenient to give “a wide view” of the band when tuning around, but once a signal of interest has been found and centered in the passband, the [NAR 1] (500 Hz bandwidth) or [NAR 2 (250 Hz bandwidth) selections are much better.
In addition to selecting various filter combinations, you have several features that can be used singly, or in combination to eliminate or reduce the interference to an acceptable level. Although their use requires little more than rotating a control, it is good to have knowl­edge on how each function works and the effect on the QRM encountered.

DEALING WITH INTERFERENCE
WIDTH CONTROL
We just saw that specific IF filters can be selected to limit the receive bandpass to a pre-set width (essen­tially the total width of the installed filter). In a crowded band, you ideally want to narrow the bandwidth just to the point where the unwanted signal is attenuated while still retaining enough bandpass to recover the desired station. In real-life band conditions, however, this ideal bandwidth is often somewhere “in-between” the sev­eral selectable filter bandwidths.
The WIDTH control can be used in all modes except FM to continuously narrow or broaden the bandpass skirt (within the limit of the selected filter) for the best skirt shaping and optimum cutoff and interference rejection during each QRM situation. Unlike older types of width con­trols that adjust both sides of the filter slope at the same time, the MARK-V FT-1000MP’s WIDTH control nar­rows the passband from either the upper or lower side (see illustration below). Thus, you only narrow the side of the bandpass where the QRM is located.
The center detent on the outer WIDTH control pro­vides maximum bandwidth, which is equal to the se­lectivity of the filter used with the operating mode. Clock-
OPERATION
wise rotation moves the upper skirt of the IF passband lower in frequency, and counter-clockwise rotation moves the lower skirt upwards. If a QRM condition occurs after tuning in a station, slowly rotate the con­trol in the direction where the interference is reduced while the station is still workable. As you rotate the con­trol you will hear the audio response change as the passband is narrowed. If the QRM is very close, the amount of bandwidth reduction necessary to cut the QRM may leave the desired station’s audio unrecov­erable, or it may not be possible to entirely eliminate the QRM.
When the QRM is all above or all below the desired signal it is usually only necessary to rotate the WIDTH control either to the left or right to cut the interference from the receiver passband. The SHIFT control (cov­ered next) will also work for this, but may introduce interference from the other side of the signal.
When you have activated the IDBT feature by press­ing the [IDBT] button on the Shuttle Jog, the EDSP (Contour) filter’s passband width reduces according to the WITDH knob setting. That is, the IF bandwidth and the EDSP bandwidth will be matched, according to the setting of the WIDTH control knob’s position.

DEALING WITH INTERFERENCE
SHIFT CONTROL
The SHIFT control tunes the relative position of the receiver IF passband with respect to the displayed fre­quency in all modes except FM. The control is detented in the center position, which represents the passband center frequency, which is also the displayed frequency. Turning the control clockwise raises the passband cen­ter frequency, while turning the knob counter-clockwise lowers it.
When QRM is present on both sides of the tuned station, first adjust the SHIFT control just to the point where the interference from one side is elimi­nated, and then rotate the WIDTH con- trol in the opposite direction to elimi­nate interference from the other side. The optimum settings of these controls depend on the relative signal strengths of the desired station and the QRM, and re­quires practice.
When you have activated the IDBT feature by press­ing the [IDBT] button on the Shuttle Jog, the EDSP (Contour) filter’s passband offset changes according to the SHIFT knob setting.
NOTCH FILTER
After tuning in a desired signal and adjusting the IF bandwidth and shift, if “heterodyne” interference such as from a carrier or CW signal occurs, activate the IF notch filter by pressing the NOTCH button and slowly adjusting the NOTCH control to null the offending car­rier. Note that if the interfering carrier is more than about ±1.2 kHz away from the center of the passband, the notch filter may be unable to null it. In this case, switch the notch filter off, and readjust the IF bandwidth and shift so that the undesired carrier is outside of the pass­band.
IF SHIFT Action
Using IF SHIFT to reduce QRM
The NOTCH feature actually has three operating modes, involving different combinations of the IF Notch filter and/or the EDSP Notch filter. You may use menu selection 2-9 to utilize only the IF Notch (IF NOTCH selection), the EDSP Notch (Auto DSP selection), or both Notch filters (SELECT). With Select engaged, any residual interference getting past the IF Notch will be eliminated by the EDSP Auto-Notch, and this combi­nation of filters provides impressive results!
SHIFT/WIDTH Tuning Steps
Rotating the SHIFT or WIDTH control tunes the IF passband using default 10-Hz steps. If desired, you can change to 20-Hz steps, which offers a faster response when turning the control knob. See menu selection 1-2 to set the default steps as desired.

DEALING WITH INTERFERENCE
CLARIFIER (R X/TX OFFSET TUNING)
The three CLAR buttons near the lower right corner of the front panel, and the control just above them, are used to offset either the receive, transmit, or both fre­quencies from their settings on the main display. The three small numbers in the center of the dis­play (just to the right of the main frequency display) show the cur­rent Clarifier offset. The Clarifier controls on the MARK- V FT-1000MP are designed to allow you to preset an offset (up to ±9.99 kHz) without actually retuning, and then to activate it with the Clarifier’s RX and TX but­tons.
Perform the following steps, if you like, to familiar­ize yourself with the Clarifier controls:
r Without pressing any of the Clarifier buttons, rotate
the CLAR knob back and forth while watching the
small center display. Notice that the small digits
change, indicating the preset Clarifier offset (which
hasn’t been applied to the Tx or Rx frequency yet)
while the main display remains unchanged. r If you press the Clarifier TX button, “CLAR”-“TX
appears below the smaller offset display, and if you
press the PTT you will see the Tx frequency shift by
the amount of Clarifier offset. r If you press RX instead, notice that “RX”-“CLAR
appears and the frequency offset is applied and the
display shifts to the offset receive frequency accord-
ingly. Press the PTT switch, and notice that the
OPERATION
transmit frequency remains the same as the origi­nal frequency display when the receive Clarifier is on. You can reset the offset to 0.00 kHz at any time by simply pressing CLEAR.
r With the RX Clarifier active, the center tuning marker
just above the main frequency display moves to the right or left as you change the offset by rotating the CLAR knob. Also notice that the main frequency and the Clarifier offset displays change together.
r Now press the Clarifier CLEAR key and observe
that the offset is cleared to zero, and the Main VFO frequency returns to what it was originally.
The Clarifier is commonly used when you are in contact with a station whose transmitter drifts (or per­haps you didn’t have him quite tuned in when you called him). You don’t want to change your transmitting fre­quency, as that would force him to retune - you just want to adjust your receiver.
Another application for the Clarifier is in a casual DX pile-up situation, where the DX station is listening in a “Split” mode (but listening “UP 5” or a similar split of less than 10 kHz). In this case, you leave the main receiver on the DX station’s frequency, then use the RX Clarifier to tune the pile-up area, listening for the station currently in QSO with the DX station. When you find that station, you can switch the TX Clarifier On and the RX Clarifier Off; you will now be receiving back on the DX station’s frequency, but you will be transmit­ting on the frequency where the DX station probably is still listening. See the discussion on page 56 regarding the use of the SPOT control for CW spotting; it speeds up the above process significantly.
Advice on QRM Reduction
Use the BANDWIDTH buttons and then the SHIFT and WIDTH controls to suppress interference. Their use varies somewhat from mode to mode.
When you are ready to retune to a new frequency, you may wish to return the SHIFT and WIDTH con­trols to their default positions (center detent). The WIDTH control can also be turned counter-clock­wise to reduce the IF bandwidth more gradually, and then the SHIFT control can be turned left or right from center to shift the center frequency lower or higher, as depicted in the drawing.
For digital modes, the wider bandwidth selections are fine for tuning around, but the 500 or 250 (Hz) bandwidths will generally give the best copy with narrow shifts. If you have the RTTY and PKT menu selections set to match your TNC/terminal unit (see page 55), you should not need to adjust the SHIFT
control at all, and the WIDTH control should only be adjusted with a great deal of care (to avoid los­ing the contact). See the section on digital modes in this manual for more details.
For 300-baud packet, use the 500 (Hz) bandwidth and keep the WIDTH control centered; the SHIFT control may require fine tuning either side of center for optimum copy of weak signals. Experiment with the SHIFT setting on a busy packet channel, and then note the optimum setting for all future HF packet operation (it will be the same unless you replace your TNC or recalibrate the input tones).
Note - except during extreme QRM conditions, the WIDTH and SHIFT controls should be left in their center (detent) positions when tuning the receiver to a new frequency. This will provide the best fidel­ity and easiest tuning.
page 49MARK-V FT-1000MP Operating Manual
OPERATION
DEALING WITH INTERFERENCE
When you finish your QSO, remember to press the Clarifier RX button again to turn off the Clarifier. You might also want to clear the offset when done.
The MARK-V FT-1000MP has an independent Clarifier for each VFO, on every band, plus one on each of the 99 memories. This means that Clarifier TX/RX and offset settings are not (improperly) carried over when you change bands or memory channels, but rather are stored in the same condition you last set them until you return to that VFO, band, sub receiver, or memory again.
OFFSET DISPLAY MODE
The small sub-panel to the right of the MAIN VFO­A display can be configured to show one of four differ­ent operating parameters.
By default the Tx or Rx Clarifier offset appears. However, this can be changed to the channel frequency, split offset (difference between VFO-A and VFO-B), or else the CW Pitch setting. Which display you choose, of course, depends on your operating habits, but can be easily changed using menu function 3-5. The fol­lowing is a brief description of each display mode.
Clarifier Settings
There are several settings that affect Clarifier op­eration and the way the frequency is displayed that you should be familiar with. After understanding their rela­tionships, you can set them as desired.
Tuning Steps -The default 10-Hz tuning steps for the Clarifier can be changed similar to the VFO’s using menu function 1-9. Choose between 0.625 Hz, 1.25 Hz,
2.5 Hz, 5 Hz, 10 Hz or 20 Hz Clarifier steps.
Clarifier M-Tune - Programmed memories can be re-tuned using the Clarifier when this is enabled (menu function 1-8). We will discuss memory tuning in detail later on.
Clarifier Offset - this 3-digit display shows the Clari­fier Tx or RX offset (±9.99 kHz) to be applied to the operating frequency.
Channel Frequency - this displays the frequency stored in the memory channel displayed to the right. If the memory has not yet been stored with data, the dis­play remains blank (except for a lone decimal point).
Offset - displays the absolute (+/–) frequency dif­ference between MAIN VFO-A and SUB VFO-B. For operators chasing DX stations working split, this makes tuning “down” easier (no mental subtraction from your operating frequency is needed).
CW Pitch - this displays the CW BFO pitch as ad­justed by the PITCH control at the lower right corner of the front panel.

TRANSMITTING
The transmitter can be activated within the 500-kHz segment of any of the HF amateur bands, and from 28 to 30 MHz. When tuned to any other frequency, “GEN” is displayed at the left side of the display, and the trans­mitter is disabled. However, you are responsible to re­strict your transmissions to those frequencies on which you are authorized to operate, per the terms of your amateur license. You should also restrict transmissions to the frequencies for which your antenna is designed.

Attempting to transmit outside of an amateur band segment will cause the red “TRANSMIT” indicator to the right of the meter to blink. The transmitter is also temporarily inhibited when stopping memory scanning (described later), as pressing the PTT switch while scanning just causes the scanner to stop.
Whenever the transmitter is activated, the MARK-V FT-1000MP automatically detects any reflected power that might appear at the main antenna jack (as a result of an impedance mismatch), and disables the transmit­ter if too much reflected power is found (in which case the red “HI SWR” indicator at the right side of the display will be lit). Although this protection system should pre­vent any damage to the transceiver, we still recommend that you never activate the transmitter without having a proper antenna connected to the main ANT jack.

SELECTING ANTENNAS
You can select between two rear-panel antenna connectors for transceive operation via the front panel, perhaps eliminating the need to utilize an external co­axial switch.
Press the A/B button to select the rear-panel jack you wish to use. The an­tenna connected to this jack is used for receive (and always for transmit). If a separate receive­only antenna is connected to the “RCA” jack labeled RX IN, and the front panel’s RX switch is pressed, the antenna connected to the RX IN jack will be used by the receiver. A relay engages during transmit, and the last-selected antenna (A or B) will be used for trans­mit. Refer to the diagram at the top of the next column.
Antenna selections are automatically copied along with other operating parameters during memory pro­gramming (covered later), and will take effect when memories are recalled later. However, if you do not want this data stored, you can select regular opera­tion, or else disable ANT switch operation. When dis­abled, antenna selection remains fixed on jack A. Re­call menu selection 8-5 to configure the ANT switch func­tion as desired.
AUTOMATIC ANTENNA MATCHING
The built-in automatic antenna tuner unit is capable of matching antenna with impedances from 20~150 Ohms, which corresponds to a maximum SWR of ap­proximately 3.0:1. If the antenna you are using exceeds this SWR as configured, it must be adjusted (mechani­cally or electrically) until a feedpoint impedance closer to 50 Ohms can be obtained.
The MARK-V FT-1000MP provides 39 tuner memo­ries, which store the exact positions of the tuning ca­pacitors and corresponding inductance values, for out­standing operating convenience.
When you use the tuner the first time on an an­tenna, set the RF PWR control to around the 9 o’clock position, to minimize interference you might cause oth­ers, and also to minimize stress on the tuner, feedline, and antenna (in case there is a high SWR). Ensure beforehand that the frequency you will transmit on is clear of other signals. Also, if you want to monitor the tuner’s action visually, set the meter IC/SWR selector to display “SWR.”
When the channel is clear, press the TUNER but­ton momentarily. The “TUNER” indicator comes on, indicating the ATU is activated, and the “WAIT” indica­tor next to it appears while the tuner seeks the proper matching settings (and, if monitoring SWR on the meter, you should see the tuner select the lowest pos­sible reading). When the “WAIT” indicator turns off, you are ready to transmit (so long as the “HI SWR” indica­tor didn’t light).
Pressing and holding in the [TUNER] button is the action which causes ATU settings to be stored into memory.
page 51MARK-V FT-1000MP Operating Manual
OPERATION
TRANSMITTING
If the SWR presented to the transceiver is above 3:1, the tuner will generally not complete the tuning process (although in certain borderline cases, it may actually be able to lower the SWR below 1.5:1). If the pre-tuning SWR is above 3:1, the auto-tuner will not store the tuning settings, under the presumption that corrective antenna work is required.
After using the antenna tuner, the “TUNER” indica­tor will remain on (unless you press the [TUNER] but­ton to turn it off), and the “WAIT” indicator will flicker momentarily when you change frequency, indicating that the main microprocessor is reporting the frequency change to the tuner coprocessor (reception is unaf­fected). If you have tuned far enough to possibly re­quire rematching, it will reset itself to the new range (if it has any previously stored settings for the new range). However, when you first connect a new antenna, the tuner will not have the correct settings stored in these memories, so you will need to “train” the tuner, by press­ing and holding the [TUNER] button for ½ second when­ever you change to a new band or frequency range (for this antenna).
If you want to use an external antenna tuner, the internal ATU should be disabled. menu selection 8-8 pro­vides a more “fail-safe” method of doing this (as op­posed to simply turning the [TUNER] switch off).
Note: The “G5RV” multiband antenna does not present an SWR below 3:1 on all HF amateur bands, despite its reputation as an “all-band” antenna. You will need to perform additional impedance matching with respect to the basic G5RV design, especially on 30, 17, and 12 meters.
SSB TRANSMISSION
To transmit in LSB or USB mode: r Make sure the appropriate mode indicator is lit, and
set the meter ALC/COMP selector to view “ALC.”
r If this is the first time you are transmitting SSB with
the MARK-V FT-1000MP, preset the MIC and RF PWR controls to about the 12 o’clock position, and make sure the VOX is off (button out).
r Check the “RX” and “TX” LEDs above the tuning
knobs to determine which frequency you’re going to transmit on, and make sure “GEN” is not show­ing to the left of the main frequency display.
r To transmit, just press the PTT (push-to-talk) switch
on your microphone, and talk.
To determine the optimum setting of the MIC con­trol for your microphone, adjust it while speaking into the microphone (at a normal level) so that the meter deflects to about midrange on voice peaks (the upper end of the red ALC range). Once found, this setting can be left as-is unless you change microphones. The proper adjustment point for most commonly-available amateur microphones is a setting between about 9 o’clock and 10 o’clock.
You can adjust the RF PWR control for more or less output, from about 5 to 200 watts (on the upper PO meter scale), as desired. However, you should al­ways use the lowest possible power output to maintain reliable communications - not only as a courtesy to other stations, but to minimize the possibility of caus­ing overload to nearby home-entertainment devices, and to reduce heat generation and maximize the life of the equipment.
Important Note
Although the antenna tuning process normally is very fast, certain difficult impedances may require as long as 50 seconds to match. This is a normal condition, however, related to the time required for the variable capacitors to make a complete search for the optimum setting with the available values of inductance.
Transmitter Monitor
The transmitter monitor is actually a separate re­ceiver circuit which picks up a sample of your trans­mitted RF signal, allowing you to hear accurately how the signal sounds. This feature is very helpful for set­ting up the speech processor controls, among other things.
Activate the monitor by pressing the orange [MONI button (below the AF GAIN control) so that its red LED lights, and adjust the MONI control beneath the meter for a comfortable volume while transmitting. Audio feed­back of your signal from the loudspeaker to the micro­phone may occur if the MONI control is not properly set, you may want to use the monitor with headphones; if so you should plug them in now.

Microphone Tone Selection
Before setting up the speech processor, set the selector switch on the rear of the MH-31B8D microphone (supplied) for the desired tone characteristic. The “2” setting suppresses low frequencies, providing more “pile-up punch” for DX operating. The “1” setting in­creases the bass response, important for maximum intelligibility when speaking in a language rich in vowel sounds (such as Japanese).
RF Speech Processor
Once the proper MIC control setting has been deter­mined, you can activate the RF speech processor to in­crease the average power of your transmitted signal.
OPERATION
To enable this feature, press the switch (located below and to the left of the Main Tun­ing dial) while operating ei­ther in USB or LSB. During Class-A operation, the PO meter will indicate up to 75 Watts of power output, while the IC meter will show a no­modulation (constant) current of approximately 10 Amps.
Although the full advantage of Class-A operation will be compromised somewhat when a (non-Class-A) linear amplifier is used, the very clean drive power from the MARK-V FT-1000MP will, nonetheless, provide a significant improvement in overall signal quality.

CLASS-A
]
r First set the METER selector to the “ALC” (Auto-
matic Level Control) position, and ensure the level is within the red zone while speaking into the mi­crophone.
r Next set the METER selector to the
COMP”(speech processor compression) position, and press the [PROC] button (at the left end of the row of buttons along the bottom) so that its red LED lights.
r Now while speaking into the micro-
phone, adjust the PROC control for a compression level of 5 to 10 dB on the COMP scale of the meter (the second scale from the bottom). If you have the monitor activated, you will be able to hear the effect of the compres­sion on your signal. In any case, we do not recom­mend higher compression settings, as your signal will actually become less readable. For the purposes of making accurate adjustments, the long utterance of the word “Four” usually provides a stable, full voice waveform, ideal for setup of the RF speech pro­cessor.
r Finally, move the METER selector back to the “PO
position, and (without touching the MIC control set­ting) adjust the RF PWR control for the desired power output on voice peaks.
Class-A Operation
A unique feature of the MARK-V FT-1000MP is the capability to operate SSB in Class A. Switching to Class A yields an ultra-linear transmitted signal, with intermodulation distortion products significantly better than possible with a typical Class AB2 transmitter de­sign.
Carrier Point Offset
This feature allows shifting the carrier point IF pass­band (and hence the RF passband as well) of your transmitted signal in the SSB mode, to customize your signal for your own voice characteristics.
Seven individual carrier settings can be user-ad­justed:
USB Carrier (Tx & Rx) - adjustable from –200 ~ +500 Hz. LSB Carrier (Tx & Rx) - adjustable from –200 ~ +500 Hz. Processor Carrier (USB & LSB) - adjustable from –200 ~ +500 Hz. AM Carrier - adjustable ±3000 Hz.
To display and adjust the various carrier settings, see menu selection 8-9. With the offset displayed, you can adjust it throughout the ranges shown above A minus sign indicates the offset is closer to the carrier (low-frequency speech emphasized). You can transmit during carrier display and adjustment.
Of course, you can adjust the offset by trial-and­error on the air, but it is better to use the built-in monitor circuit or a monitor receiver, in which you can hear the effect yourself. Otherwise, we recom­mend starting with +0.10 (+100 Hz) offset initially, to add some “crispness” to your processed speech.
Because Class A involves a total current dissipa­tion much greater than utilized for Class AB, to which you’re probably accustomed, maximum power output during Class A is limited to 75 Watts as indicated on the PO meter.

OPERATION
TRANSMITTING
VOX Operation (Voice-Actuated T/R Switching Operation)
VOX operation allows you to activate the transmit-
ter in any voice mode merely by speaking into the mi­crophone, without having to press the PTT switch.
For the VOX circuit to operate properly, three con-
trols in the top access panel must be set to match your microphone and the acoustic environment of your sta­tion. Once set, these controls should not require read­justment unless you change your microphone or sta­tion location.
r First make sure the receiver is set for normal vol-
ume on a clear channel, and preset the VOX (gain) control in the top access panel fully counterclock­wise. Also preset the A-VOX (Anti-VOX) and DLAY (VOX Delay) controls in the top access panel to their 12 o’clock positions.
r Set the RF PWR control fully CCW (to avoid creat-
ing interference while you set up the VOX controls). Now press the [VOX] switch near the upper left cor­ner of the front panel.
r Without pressing the PTT switch, speak continu-
ously into the microphone while slowly adjusting the VOX control (in the top access panel), looking for the point where your voice just activates the trans­mitter. Advancing the VOX Gain control beyond this point will make the VOX excessively sensitive to random background noise in your operating room.
r Now speak intermittently into the microphone, and
note the “hang time” between the moment you stop speaking and when the receiver is reactivated. This period should be just long enough so that the trans­mitter remains keyed between words, but drops back to receive during pauses. Adjust the DLAY control, if necessary, for a comfortable hang time.
The A-VOX control probably needs no adjustment,
but if you find that, with the microphone in its normal operating position, receiver audio from the loudspeaker trips the transmitter, advance the A-VOX control more clockwise. On the other hand, if transmitter keying with the VOX keying seems sluggish or unstable when you speak into the microphone, try a more counter-clock­wise setting.
CW TRANSMISSION
There are several types of CW transmission avail­able with the MARK-V FT-1000MP. All require that you have a CW key or keyer paddles connected to either of the KEY jacks on the front or rear panel (with a 3­contact plug). You simply use the RF PWR control to set your output power.
Straight-Key Operation
r First preset the RF PWR control to about 12 o’clock.
Select the CW mode, if you haven’t already, and for
now, make sure the [KEYER] and [BK-IN] switches
near the lower right corner of the front panel are
both off.
r Press the [VOX] button to turn on the VOX circuit,
which provides automatic transmitter activation
when you close your key. If you want to practice
CW with the sidetone, you can leave the VOX off. r To transmit, simply close your key and advance the
RF PWR control for the desired power output level. r You can adjust the CW sidetone volume, if neces-
sary, for a comfortable level using the trimmer ac-
cessible via the hole on the rear panel (see item #3
on page 34). r Release the key to return to receive.
You are now using semi break-in CW, in which the transmitter remains activated except during pauses in your sending. You can set the delay during which the transmitter remains on after you stop sending, by ad­justing the keyer delay setting (menu selection 7-5).
However, if you prefer full break-in (QSK) opera­tion, in which the receiver is activated between each dot and dash, simply press the [BK-IN] switch (the [
VOX] switch should not be depressed).

OPERATION
Electronic Keyer Operation
The built-in electronic keyer offers two iambic modes and a mechanical “bug” keyer emulation. You will need to connect keyer paddles to one of the KEY jacks to use the keyer.
The keyer is set at the factory for iambic keying, in which one keyer paddle produces dots, and the other dashes. Squeezing both produces alternating dits and dahs. Menu selection 7-0 allows choosing three keyer modes:
Iambic 1 - Iambic keyer with ACS (Auto-Character Spacing) disabled. Weighting is user-selectable via menu selections 7-1 & 7-2.
Iambic 2 - Iambic keyer with ACS enabled. Weight­ing is set via menu selections 7-1 & 7-2.
BUG - Emulates mechanical “bug” keyer (one paddle produces dits and the other is used to produce dahs manually (like a straight key)).
Once the transceiver has been set up for CW trans­mission as just described, you can activate the keyer with the [KEYER] pushbutton near the lower right corner of the front panel (its red LED should light). Now squeeze the paddles, and adjust the SPEED control for the de­sired sending speed (if you are using the bug simulator mode, don’t squeeze both paddles; just press the “dot” paddle).
ACS (Auto Character Spacing)
This feature improves your CW sending quality by ensuring the inter-character spacing of dots and dashes remains constant. Although dot/dash weighting is au­tomatically maintained at the desired ratio, the inter­character spacing can sometimes vary from operator to operator, and proportional spacing is sometimes not maintained. This does not present much of a problem during slow CW sending, but at higher speeds, the ef­fect is more pronounced and sometimes makes copy difficult.
ACS works on the principle that the spacing be­tween characters should be 3x the duration of the “dot.” If you utilize the standard 3:1 dash:dot ratio, this also happens to be the same duration of a “dash.” Main­taining this inter-character spacing is what prevents the sent characters “E” and “T,” for example, from merg­ing into what sounds like the character “A” (see illus­tration).
ACS is activated when keyer mode “Iambic 2” is selected from menu function 7-0. For memory keyer programming using the optional FH-1 Keypad, you should always use keyer mode Iambic 2 during mes­sage programming, although you can switch back to Iambic 1 after the messages are loaded, if Iambic 1 is more comfortable for you.
If the dot:space and/or dash:space weighting are not to your preference, see menu selections 7-1 and 7-2 to configure your keyer’s settings.
You can use the keyer for both semi and full break­in keying, as described in the previous section.

Keyer Delay - For QSK (break-in) CW operation,
the switchover time delay from Tx to Rx can be ad­justed from 0 seconds (full break-in) to 5.10 seconds (in 10-msec) using menu selection 7-5. Note that this provides a separate “hang time” adjustment from the “VOX Delay” setting used during voice operation.
CW Break-In - The switching time of the CW car-
rier waveform can be adjusted from 0 to 30 millisec­onds for use with linear amplifiers with T/R switching circuits not designed for full-QSK operation. This fea­ture provides a programmable delay in the total CW envelope character string,not a simple truncation of the first character. menu selection 7-4 controls the time de­lay. See also “Linear Amplifier Operation” on page 12 for more details.
transceiver’s SPOT tone with that of the station being worked by the DX station, so as to be “next in line” on the same frequency. This SPOT signal is centered in the receiver section’s IF passband, as well, which en­sures that you will not lose track of his signal when switching to a narrower filter. Of course, you must turn off the [SPOT] switch once frequency alignment has been completed.
The CW pitch can be set from 300 ~ 1050 Hz (in 50-Hz increments) to match your personal operating preference. The CW Pitch feature adjusts the amount of offset from “zero beat” of your CW carrier, as well as the corresponding pitch of the CW SPOT tone; it also adjusts the center frequency of the receiver’s IF pass­band, so as to be aligned with the other offset param­eters just mentioned. The CW Pitch may also be ad­justed to match that used by popular TNC (Terminal Node Controller) units and other CW decoders. While adjusting the pitch, you can have the frequency shown in the Clarifier sub-display by enabling it via menu se- lection 3-5.
CW Pitch Setting and Spot Tone
In the CW mode (only), pressing the [SPOT] switch on the lower edge of the front panel activates the CW sidetone, which is also used as a spotting oscillator. The frequency of this tone is also (exactly) the fre­quency at which your transmitted signal will appear relative to that of the incoming sig­nal.
Therefore, if you match the pitch of the SPOT oscillator’s tone to the pitch of an incoming signal, you will be exactly “zero beat” with that station’s CW sig­nal. In a DX pile-up situation, you can match your
To adjust the CW pitch (and SPOT tone along with it), press the [SPOT] switch, then rotate the PITCH con­trol to set the tone to the pitch you prefer, or that used by your TNC or CW decoder. If the sub display is en­abled for indication of the CW pitch, you can view the pitch frequency as you adjust it. The SPOT tone vol­ume can be adjusted using the SIDETONE potentiom­eter, accessible on the rear panel of the transceiver).
In addition to the spotting oscillator, the directional tuning meter provides a constant visual indication of any signal at the center of the IF passband (if not too weak). You can just tune so that the segment flashes in sync with the signal of interest when it is centered (see page 41).

OPERATION
AM TRANSMISSION
Transmitter setup for the AM mode is essentially the same as for LSB or USB, except that you must avoid overmodulating, and limit carrier power to 50 watts. This carrier level ensures that sufficient power is available for the voice sideband envelopes.
r VOX can be used in the AM mode, but for now,
make sure the [VOX] switch is off, so as not to con-
fuse adjustments. r With the AM mode selected, press the METER
[
ALC/COMP] button to view the ALC range.
r Press the PTT switch, and rotate the RF PWR con-
trol for the desired power output (remember to limit
transmitter carrier power to 50 watts in the AM
mode). r If you have already set the MIC control as described
for SSB transmission, there should be no need to
readjust it. If not, close the PTT switch, and adjust
this control just to the point where the ALC begins
to deflect slightly, and stays within the red ALC zone.
Don’t set it too far beyond this point, or your signal
will become distorted from over-modulation. r The transmit monitor is very helpful in setting the
correct modulation level, and if you have head-
phones on, you should turn the monitor on now.
Note that the speech processor is disabled in the AM mode. You can, however, activate the VOX, if de­sired.
DIGITAL MODE OPERATION
Information regarding connection of your MARK-V
FT-1000MP to commonly-available digital-mode mo-
dem devices is presented beginning on page 15.
Operating practices generally are governed by de­tails provided in the operating manual for the TNC or modem you are using. However, a few guidelines are presented below, to help you get on the air quickly.
RTTY Operation
To operate, just press the RTTY mode button once or twice to select the desired sideband for operation. LSB is default, and is used by normal convention (USB can be selected for MARS or other applications). Should you need reverse tone polarity or non-standard shift (other than 170 Hz), configure menu selection 6-1 and 6-2 as desired.

300-Baud Packet
Construct a patch cable as required, and connect your TNC to the rear-panel PACKET jack. Do not con­nect the squelch line (pin 5) for 300-baud packet op­eration.
Tuning is very critical for F1 packet: you should tune the transmitter and receiver within 10 Hz of a signal to minimize repeats. The MARK-V FT-1000MP includes a few custom features to make packet operation more convenient.
Packet Tone Pair - This offsets the center of the IF bandpass according to the packet tone pair you are using. If set correctly, the receiver passband will re­main centered on a properly-tuned packet station when switching between wide and narrow IF filters, minimiz-

ing the need for re-tuning or use of the SHIFT control for re-centering.
One of four standard tone pairs can be chosen for operation from menu selection 6-5, as desired. The menu display shows the center frequency of the selected tone pair (see the table below for actual mark/space tone combinations). Set the Packet Tone Pair to match the tones generated by your TNC (these are usually set via terminal software or DIP switches - check in your TNC documentation).
Important Note! - if changing packet tone pair to other than 2025/2225 Hz, be sure to re-calibrate the tuning meter as outlined on page 85. The calibration routine is simple, and ensures your center tuning indi­cation matches the tone pair.
Packet Frequency Display Offset - You can dis­play the center frequency of the two transmitted carri­ers, (that is, the packet tone pair used), without any offset, instead of the actual carrier frequency. Recall menu selection 6-4 and turn the main knob to select the offset (±3.000 kHz).
Note - The default display offset is -2.125 kHz (to match the default tone pair* in 6-5 above, and assum­ing LSB operation). Ideally, the display offset should match the default tone pair, which in turn should match those used by your TNC. If you would rather have the actual carrier frequency (without offset) displayed, set the display offset to 0.000 kHz.
Packet Operation
Select the NAR 2 (500-Hz or 250-Hz) filter for 300­baud packet, and press the [PKT] mode button on the front panel once or twice, so that the green LSB LED indicator lights along with the red PKT LED.
Transmitter adjustment is similar to SSB: r Preset the RF PWR control counterclockwise, and
set the METER selector to “ALC.” r Now set your TNC to its “calibrate” mode, prefer-
ably with both tones alternating, and adjust the MIC
control so that the meter deflects to mid-scale. Your
TNC’s “TX Audio” output may also be capable of
adjustment via a potentiometer inside the TNC. r Switch the METER selector to “PO” and advance
the RF PWR control for the desired power output.
When tuning, be aware that some common HF packet channels, such as “14.103” MHz, were origi­nally determined to correspond with an actual IF cen­ter frequency 1700 Hz lower (in accordance with an old TAPR convention). Therefore, if you have the Packet Frequency Display Offset (menu selection 6-4) set to match your TNC’s actual tones, the display shows
14.101.30 when tuned to the above frequency - which is the actual center of your receiver passband, and the frequency mid-way between the two FSK carriers you will transmit.
Initially, you may need to adjust the receiver IF shift slightly right or left to get the 500-Hz IF filters perfectly centered over incoming signals. Start with the SHIFT control centered, and try to establish a connection with a moderately strong signal on a clear channel. If the connection is poor (many repeats), move the SHIFT control slightly right, and see if the repeats decline. Continue in this manner until you find the best SHIFT setting (with minimal repeats), and use this same set­ting for all future HF packet operation.
1200-Baud FM Packet
The equipment setup for 1200-baud FM packet (above 29 MHz) is the same as for 300-baud packet, except that you may want to connect the squelch line of the TNC to pin 5 of the PACKET jack if you plan to use the squelch. Press the [PKT] mode switch until both it and the green LED on the FM mode button are lit. Tuning is much less critical in this mode, requiring no special adjustments. Also, the FM MIC GAIN con­trol in the top access panel has been preset at the fac­tory for proper deviation with typical signal levels, so you should not need to readjust it (you should adjust the Tx audio output level of your TNC, though, if your signal sounds distorted in the monitor).
To set up the transmitter for FM packet:
r Start with the RF PWR control counterclockwise. r Switch the METER selector to “PO” and set the RF
PWR control for the desired power output.

OPERATION
FM TRANSMISSION
A separate, dedicated “29 MHz” band is provided on the MARK-V FT-1000MP, allowing you to operate both on 28 MHz in narrow-band modes, and above 29 MHz using narrow-band FM. This relieves you of the need to change all your configurations when switching voice modes.
For transmission, the only control on the front panel you need be concerned about is RF PWR. Microphone gain for FM is set via the separate FM MIC control in the top access panel, and normally needs no adjust­ment after leaving the factory. If you receive signals reports of low audio with a strong carrier, you may want to increase the gain. If you notice distortion in the trans­mit monitor, you may want to decrease it. Otherwise, we suggest leaving it alone. Remember that the ap­parent modulation level on 29 MHz will be less than you are accustomed to on VHF, due to international regulations restricting the maximum deviation to ±2.5 kHz.
All you need to do for most operation is set the
METER selector to the “PO” position, and adjust the RF PWR control for the desired output while transmit-
ting. If you need full power, keep your transmissions to three minutes or less, with the same time for recep­tion. Otherwise, set the power output to 100 Watts or less, and you should never encounter any duty cycle limitations.
You can use the VOX circuit for t/r switching, if de­sired, and the transmit monitor to listen to your signal. See also the FM Repeater Operation at the right.
FM Repeater Operation
Several features are available for operation on FM repeaters above 29 MHz, which typically use 100-kHz splits.
To locate these repeaters, you can ask around the calling channel (29.6 MHz), or you may want to load a block of memory channels (see page 67) with 50-kHz frequency multiples from 29.61 to 29.7 MHz (and FM mode, of course). Then set the squelch so that the receiver is silent on a clear channel, and hold the mi­crophone UP/DWN keys to scan the memories.
Repeater Shift - When you find a repeater, press the [RPT] button, once for “–” shift (to transmit 100 kHz below your receiving frequency). Pressing it again will select “+” shift, but this is not used above 29.6 MHz. Press it once more to re­turn to simplex. Try a quick identification transmission to make sure you have the shift right.
Repeater TX Offset - For repeaters not using the standard 100 kHz offfset, you can change the default offset between 0 ~ 200 kHz via menu selection 6-9.
CTCSS Tone - A low-level 88.5-Hz subaudible tone is transmitted to access closed repeaters. Should a different CTCSS tone be required, you can choose any one of 33 standard tones via menu selection 6-7.
Tone Type – Continuous (CTCSS) or burst tone transmission is enabled from menu selection 6-8.

Operation
USING SUB VFO B
The Sub VFO works in a similar manner to the Main VFO, with which you should be familiar by now. The Sub VFO provides simple split (transmit/receive) fre­quency operation via the combination of the MAIN VFO’s RX and TX LED/Buttons and the SUB VFO’s RX and TX LED Buttons, and, more importantly, dual­channel reception via the [DUAL] button. We’ll get into those in a minute, but first let’s look at how to control the Sub VFO.
Frequency, mode, and Clarifier data can be trans­ferred from the Main VFO to the Sub VFO by pressing [
AuB], but don’t forget that this will overwrite any set-
tings that were in the Sub VFO previously. Also, the contents of the two VFOs can be swapped (with no loss of data) by pressing [AuB].
Most selections for the Main VFO can also be made for the Sub VFO directly, by pressing [SUB(CE)] right before another keypad key to select a band, or before a mode button to change the Sub VFO mode (displayed below the Sub VFO frequency). When you press the [
SUB(CE)] key, the entire display for the Sub VFO will
blink, after which you have five seconds to press an­other key. Note that to switch VFO registers in the Sub VFO, you need merely press the [SUB(CE)] key fol­lowed by the key for the same band that the Sub VFO is already on.
r To set the Sub VFO (if it currently is on 7.000.0

Unlike the Main VFO, with its triple-conversion re­ceiver, the Sub VFO receiver uses double-conversion circuitry with 47 MHz and 455 kHz intermediate fre­quencies. Filters are selected automatically in the sub receiver, according to the operating mode. A 6-kHz AM filter and 2.4-kHz SSB/CW filter come installed from the factory. For CW work, a third optional 500-Hz nar­row filter is also available from your dealer. After instal­lation, this filter pathway must be enabled via menu selection 5-8. During operation, you can select this filter by pressing [SUB(CE)] ð [NAR1 [
NAR2].
Of course, you can tune the Sub VFO using its tun­ing knob, and use faster tuning steps by holding the [
FAST] button (below the left side of the main tuning
knob). You can use the large DOWN keys (in both normal and 1-MHz fast steps) for the Sub VFO as well, if you just press the [SUB(CE)] key first.

DUAL RECEPTION
Pressing the blue [DUAL] button activates the SUB VFO-B receiver. The “DUAL” indicator will appear at the left of the display, and the green “RX” LED above the SUB VFO-B tuning knob lights. Instead of press­ing the blue [DUAL] button, you also can simply press the green “RX” LED, as this actually is a combined switch/LED.
Dual receive operation opens up exciting operating possibilities for split operation, contesting, and chas­ing elusive DX stations. For split-frequency DX pile­ups the ability to listen to both “sides” of the pile-up allows very precise timing of your calls. For contest­ing, dual receive allows you to continue a “run” on your “main” frequency while keeping an ear on a DX “multi­plier” that might not be listening for your call area, for example.
The Main and Sub VFO share the same antenna and front-end bandpass filter, and so should be tuned fairly close to each other for maximum sensitivity (that is, within 500 kHz or so at low frequencies, or within several MHz at higher frequencies). Although you may be able to receive on, say, 21 and 28 MHz at the same time, you may find the SUB VFO-B receiver signal at-
)]
tenuated.
There are 12 BPF networks in the receiver front­end circuitry, each covering a particular segment of the transceiver’s full receive range. SUB VFO-B receiver specifications are only guaranteed while tuning within the same bandpass as the MAIN VFO-A.
Main and Sub VFO Audio
The AF GAIN knob controls the Main VFO’s vol­ume level, and the smaller SUB AF knob controls the Sub VFO’s volume. The effect these controls have on receiver audio can be changed, and is configured us­ing menu selection 4-9. AF GAIN control knob opera­tion can be set to either of the two following modes:
Separate - The receiver volume for the Main and Sub VFOs is adjusted independently. This simply means that the AF GAIN knob controls the MAIN VFO­A volume and the small SUB AF knob controls the Sub VFO’s volume.
page 60 MARK-V FT-1000MP Operating Manual
USING SUB VFO B
Balance - The AF GAIN knob adjusts the volume for both the Main and Sub VFOs simultaneously. The small SUB AF now functions as a “balance” control between Main and Sub audio levels.
Note - To “reverse” Main and Sub receiver audio at any time, press the [AF REV] button just to the left of the DOWN tions of the AF GAIN and small SUB AF controls are now switched. Press the button again to return to nor­mal operation.

Operation
Note that both the Main and Sub VFOs must be activated (to put the MARK-V FT-1000MP into the dual receive mode), and the AF GAIN control(s) must be balanced (centered) to hear both receivers. Compare these two positions with both VFOs tuned to signals, to select the audio mixing scheme you prefer.
Also observe that the VRF, EDSP, RF GAIN, SHIFT, WIDTH, NOTCH, and AGC functions do not affect the sub receiver (AGC is automatically selected according to mode, or else from menu selection 8-7).
Remember that when the Sub VFO is turned off by pressing [DUAL] again, the AF GAIN control configu­rations no longer apply.
Using Headphones for Dual Receive
To take advantage of dual reception, you will want to connect stereo headphones to the PHONES jack. Like the AF GAIN control, headphone audio mixing can also be configured as desired from menu selection 4-8. Three audio mixing schemes are selectable as follows:
Mono - Audio from both the Main and Sub receiver is combined equally in both ears (as from the loud­speaker when headphones are not used).
Stereo 1 - This is a combination of the audio from the two receivers and it gives you some audio from each channel in each ear, but with the Main receiver emphasized in the left ear, and the Sub receiver em­phasized in the right ear, resulting in a kind of “3-D” spatial audio effect.
Stereo 2 - Audio from the Main receiver is only heard in the left ear, and audio from the Sub receiver is heard only in the right ear.
Headphone Audio Adjustments
The Main and Sub receiver audio levels available from headphone jacks A and B are manually adjust­able. Underneath the top panel access cover are four trimpots allowing individual adjustment of Main and Sub audio for each headphone jack. With a headphone in­serted into the appropriate jack, you can rotate these controls using a small insulated screwdriver for opti­mum level and balance. Refer to the drawing below for trimpot locations.

Operation
USING SUB VFO B
SPLIT FREQUENCY OPERATION
Typical split operation involves receiving on the Main VFO-A or a memory channel, and transmitting on the Sub VFO-B. The special case of FM repeater opera­tion uses some features of its own, and is described on page 59.
Rare DX stations often announce that they will “lis­ten up” or “listen down” a few kHz (from their Tx fre­quency) when calling CQ or during contests to avoid being covered by the DX pileup from responding sta­tions.
To activate Split operation, press the (TX) Button/ LED above the Sub VFO’s tuning knob. “SPLIT” will appear at the left of the display, and the red TX LED above the Sub VFO tuning knob will light up. Split op­eration can be activated with or without dual reception; however, we recommend that you have dual receive on, to allow you to monitor your transmit frequency on the Sub VFO (while receiving), as well as the Main VFO receiving frequency, so you don’t accidentally “step on” somebody.
A few button functions you will need to know for split operation are explained below.
Split Operation Mode
The MARK-V FT-1000MP offers three modes of
Split operation (chosen by menu selection 8-2):
Normal - In this default configuration, pressing SUB
VFO-B (TX) Button/LED activates Sub VFO-B for
transmission. Other settings (such as mode and fre­quency) must be manually set for the Sub VFO.
Auto - When SUB VFO-B (TX) Button/LED is pressed, Sub VFO-B is enabled for transmit, and the selected operating mode from Main VFO-A is automati­cally copied into Sub VFO-B. The transmission fre­quency must still be manually set for the Sub VFO.
A=B - Same as Auto mode above, however, a pre­set frequency offset (known as a “Quick Split”) is also applied to Sub VFO-B for transmission.
The “Quick Split” feature is handy when you know the offset a DX station will be listening on beforehand. The offset is applied instantly, saving time and mental arithmetic. It also ensures that you will not be transmit­ting on the DX station’s TX frequency! A Quick Split offset up to ±100 kHz can be selected in menu selec- tion 1-6.
SUB VFO-B (TX) Button/LED - Pressing this but-
ton activates the Sub VFO for transmission.
[
AuB] - Pressing this key copies the displayed con-
tents of the Main VFO into the Sub VFO, overwriting its previous contents.
u
[
A
t
B] - Pressing this key switches “trades” the dis-
played contents of the Main and Sub VFOs.
SUB VFO-B Settings
S-Meter - You can enable or disable the S-meter for the sub receiver via menu selection 3-6.
Peak-Hold - Additionally, if you want the “peak-hold” meter function (see page 41) for the Sub Receiver S-meter, it can be turned on/off by menu selection 3-8.
Tuning Steps - The Sub VFO’s step size (0.625 ~ 20 Hz) is selected in menu selection 1-4.
Sub Receiver AGC - The AGC recovery time con­stant can be switched from automatic (default) to either fast or slow using menu selection 8-7.
Filters - When installed, the optional 500-Hz IF fil­ter can be selected from the front-panel via menu selection 5-8.
Lastly, if you want to disable SUB VFO-B opera­tion entirely, it can be turned off from menu selec- tion 7-8 (the display still appears and the SUB VFO­B knob can be turned, but nothing is received). While disabled, the sub receiver can be activated as a separate transmit VFO for split operation by pressing the SUB VFO-B (TX) Button/LED.

USING SUB VFO B
Operation
SIDEBAND DIVERSITY RECEPTION
Here you receive a single AM signal through the two receivers, each receiving the opposite sideband. Skywave-propagated signals often show phase distor­tion in this mode, but it gives you a view of the entire passband, from which you can then select the best sideband for listening (or for SWL Dx’ing, you may want to listen to both sidebands at the same time, to get the best copy). On groundwave signals, where the phase of the sidebands is likely to be the same, there is an interesting sense of depth to the signal.
To tune in a signal using this mode, you should have stereo headphones connected to the front panel PHONES jack, or an external stereo amplifier con­nected to the rear panel AF OUT jack.
r Set the Main VFO to either LSB or USB mode, and
tune for zero beat on the desired signal. r Press [AuB] to copy this mode and frequency into
the Sub VFO, then press the mode button to select
the opposite sideband for the Main VFO. r If using headphones, set the headphone mixing
scheme to the Stereo 1 mode, and press [DUAL] to
activate dual reception. Adjust the AF GAIN
control(s) to balance the volume of the two receiv-
ers.
BANDWIDTH DIVERSITY RECEPTION
This mode involves receiving the same signal through two different bandpass filters. The frequency and mode of each VFO is the same. The main receiver provides a narrow bandpass, and the sub receiver a wide bandpass, resulting in a spatial perception of the channel. Although any mode (except FM) can be used, CW offers the widest array of choices, and perhaps the most startling effects on crowded channels.
Stereo headphones or an external stereo amplifier are recommended for this mode. To set up the trans­ceiver for bandwidth diversity reception:
r Select the desired mode on the Main VFO, and the
press the [NOR] or [NAR1] button (its LED will light
up).
r Tune to the signal of interest. r Press [AuB] to copy this mode and frequency into
the Sub VFO, then press the [NAR 2] button to se-
lect a narrow filter for the Main VFO. r If using headphones, set the headphone mixing
scheme to the Stereo 1 mode and press [DUAL] to
activate dual reception. Next adjust the AF GAIN
control(s) to balance the volume of the two receiv-
ers. If using an external amplifier, adjust its balance
control.
If interference is present on one of the channels, you may have to turn its AF GAIN control to suppress that channel (or press the green “RX” switch/LED to disable the receiver with the sideband experiencing interference). Otherwise, try changing the headphone audio mixing scheme to Stereo 2 or Mono in the menu selection for different effects (or try settings with simi­lar effects on your external amplifier). Although you don’t get the “stereophonic” effect in the monaural mode, the two signals are still mixed, offering the potential for much better copy than in regular AM or even single­sideband ECSS modes.
You also may find it interesting to try the SHIFT and WIDTH controls (on the Main receiver) for some inter­esting effects.
Before retuning, remember to press [DUAL] to turn off dual reception.
VFO TRACKING
To have Sub VFO B track the Main Receiver VFO while tuning (with dual reception on or off), simply hold the [LOCK] button depressed.
With [LOCK] depressed, the “TRACK” indicator ap­pears when the main tuning knob is rotated, and the Sub VFO tracks the Main receiver. Release the button to resume normal tuning.

Memory Features
MEMORY STRUCTURE
The MARK-V FT-1000MP contains ninety-nine regular memories, labeled 1-1 through 1-99, nine spe­cial programmed limit memories, labeled P1 through P9, and five QMB (Quick Memory Bank) memories, labeled C1~C5. Each stores the Main VFO’s frequency and mode, IF filter selections, Clarifier on/off and off­set settings, as well as Repeater Shift status (if appro­priate). By default, the 99 regular memories are con­tained in one group; however, they can be arranged in up to 5 separate groups if desired.
Like during VFO operation, you can freely tune and change the mode or Clarifier settings and you can also copy settings from one memory to another. In fact, you can do nearly anything with a memory that you can with the VFOs, except for the special PMS memories (P1~P0), described later.
The [VFO/MEM], [AuM], [MuA] and [M CK] but­tons and VRF/MEM CH knob are used to control vari­ous memory operations, as follows:
[
r
VFO/MEM] - This toggles control between memory or VFO operation. If a displayed memory has been re-tuned, pressing [VFO/MEM] once returns to the originally-memorized frequency, and pressing it again returns to the last-used VFO. [
r
AuM] - When receiving on a VFO or re-tuned
memory, pressing and holding in this key for ½ sec­ond stores the current operating data into the cur­rently selected memory. Two beeps sound, and any previous data in that memory register will be over­written. Momentarily pressing this key activates memory checking (“MCK” blinks) for 3 seconds. This is described in the next section on memory storage and recall. [
r
MuA] - Pressing and holding in this key for ½ sec-
ond copies the frequency and operating data stored in a selected memory into the Main VFO. Momen- tarily pressing this key activates memory checking (“MCK” blinks) for 3 seconds. This is described in the next section on memory storage and recall. [
r
M CK] - Pressing this key also activates memory
checking (to look at the current contents of a memory or memories) and displays the contents of the memory channels in the right Sub VFO display.
r VRF/MEM CH - This knob selects the memory
channel while memory operation. However, when the VRF feature is engaged, this knob tune the pass­band of the narrow input “preselector” filter. In this instance, press this knob momentarily to change this knob’s operation to that of memory channel se­lection.
page 64 MARK-V FT-1000MP Operating Manual
MEMORY PROGRAMMING
Memory programming allows storing your favorite or often-used frequencies into memory channels for long-term storage and quick recall. The MARK-V FT- 1000MP memories are retained after power-off by a long-life lithium backup battery that should not need to replaced for more than 5 years. Should you expect to not use your transceiver for extended periods, you can switch off the backup battery via the rear panel switch to conserve lithium backup battery life (see page 114).
COPYING VFO-A DATA TO SELECTED MEMOR Y
You can store the frequency and all operational settings for the displayed (Main) VFO into a memory channel by following this simple procedure:
r Set up all operating parameters and frequency as
desired on the Main VFO.
r When the VRF feature is engaged, press the VRF/
MEM CH knob momentarily to change the VRF/
MEM CH knob’s operation to that of memory chan-
nel selection. r Rotate the VRF/MEM CH knob to select the memory
channel to fill (“MCK” will start blinking). r When you have chosen a channel into which to store
the frequency data, press and hold in [AuM] for ½
second so that two beeps sound. The VFO con-
tents are now stored in the selected memory chan-
nel; at this point, you remain in the VFO mode, so
you can continue tuning around and/or storing ad-
ditional memories.
Memory Features
Auto Channel-Up
Normally, you must manually increment the chan­nel number when programming consecutive memories. If you would like to save time and have the channel number automatically increment after writing each memory, this can be enabled in menu selection 0-8.
Notice
Regarding the VRF/MEM CH Knob
When the VRF feature is engaged, the VRF/MEM CH knob tunes the passband of the narrow input
“Preselector” filter. During Memory operation, to enable memory channel selection, press the VRF/ MEM CH knob momentarily; rotation of the knob will now allow you to select other memories. And if you want to enter the “Memory Tune” mode and step around in channelized steps (per the setting of menu selection 1-5), press and hold in the VRF/
MEM CH knob for ½ second.
Basic Memory Storage Procedure
page 65MARK-V FT-1000MP Operating Manual
Memory Features
RECALLING & OPERATING ON MEMORY CHANNELS
To recall a memory stored per the previous sec-
tion, you first must switch to the “Memory” mode. To do this, while operating on the Main VFO, press [VFO/
MEM]. The last-utilized memory’s contents will appear
in the main frequency display field. To return to VFO operation, just press [VFO/MEM] once more; the VFO’s contents will have remained undisturbed.
While operating in the memory mode (if you haven’t
yet re-tuned it - see below), the “MEM” indicator is dis­played instead of “VFO,” and you can now rotate the VRF/MEM CH knob or press the microphone UP/DWN buttons to select any previously-stored memories for operation.
Pressing and holding in the [MuA] key for ½ sec-
ond copies the current memory channel data into VFO­A. You can now tune around on the Main VFO, having used the memory channel’s frequency as a starting point. When you press and hold in [MuA], you lose the previous contents of the Main VFO, and if you were receiving on the VFO, operation shifts to the frequency and mode just copied from the memory.
Pressing the [MuA] key momentarily shows you
the contents of the memory, without overwriting VFO­A data. This is a momentary version of the [M CK] key’s action.
MEMORY TUNING
With this mode, you can emulate VFO tuning and
operation on a memory channel and retain the memory checking feature: if you change frequency, mode or Clari­fier settings, “MEM” is replaced with “MTUNE”. During memory tuning, the microphone UP/DWN buttons now duplicate tuning knob functions like VFO operation (rather than select memory channels as before). Press­ing [VFO(MEM)] once cancels any re-tuning changes to the memory and reverts to the memory recall mode (“MEM” displayed again). Pressing [VFO/MEM] once more returns the transceiver to VFO operation.
Memory Tuning makes operation on memories 1
to 99 just as flexible as the VFOs (memories P1 ~ P9 have special additional features, described later). If you want to save changes to a re-tuned memory channel, use the same procedure you use to store the VFOs to memory: Press [VFO/MEM] momentarily, and rotate the VRF/MEM CH knob to select another memory (if desired), or just hold [AuM] for ½-second until the double beep sounds (to overwrite the current memory with the re-tuned data).
Important Note: Computer software programs uti­lizing the CAT system interface port may presume that the transceiver is operating in the VFO mode for certain features like “band mapping” and/or frequency logging. Because the “Memory Tune” mode so closely resembles the VFO mode, be sure that you have the MARK-V FT-1000MP operating in a control mode com­patible with your software’s requirements.
MEMORY CHECKING
Before storing or recalling a memory, you will usu­ally want to check its contents. One memory channel number is displayed at all times (just to the left of the CH indicator at the right center of the display). You can change the selected channel number by rotating the VRF/MEM CH knob.
If you rotate this knob while receiving on the VFO or a re-tuned memory, “MCK” blinks beneath the chan­nel number, and the mode and frequency previously stored in the selected channel will be displayed in place of the SUB VFO-B display. for three seconds after you stop turning the knob. If the memory is vacant, “CLEAR” appears above the channel number and nothing is dis­played except two decimal points.
You can also view memories by pressing [M CK], in which case memory data is continuously displayed (“MCK” remains on and doesn’t blink). You must press [
M CK] again to return the display to the VFO.
Momentarily pressing either [AuM] or [MuA] also activates memory checking. As mentioned before, “MCK” blinks as the frequency and mode indicators change to show the contents of the last-selected memory. If you touch nothing else, the display reverts to your current operating parameters automatically af­ter 3 seconds. By turning the front panel VRF/MEM CH knob before the 3 seconds expires, you can select for display each of the general purpose and PMS memories. Pressing these buttons restarts the 3-sec­ond timer, so as long as you are changing channels, memory checking mode persists.
Note: When checking memories, both vacant and filled memories are displayed. If you would like to skip over vacant memories, press the [FAST] button be­fore memory checking.
The labeling and function of [AuM] during memory tuning is somewhat deceptive as the VFO settings, which are hidden at this point, are not involved in this operation at all, since those of the recalled memory have taken their place.

Memory Features
RECALLING & OPERATING ON MEMORY CHANNELS
COPYING A SELECTED MEMORY TO VFO-A
If desired, you can store the frequency and all op­erational settings for the selected memory channel into the Main VFO. While operating in the Memory mode:
r When the VRF feature is engaged, press the VRF/
MEM CH knob momentarily to change the VRF/
MEM CH knob’s operation to that of memory chan-
nel selection. r Rotate the VRF/MEM CH knob (“MCK” blinks) to
select the memory channel to copy. r Press and hold in the [MuA] key for ½ second so
that two beeps sound. The memory channel data is
now copied to the Main VFO, and you are left oper-
ating on the VFO.
COPYING BETWEEN M EMORIES
The same procedure for copying VFO-A into memo­ries is also used to copy one memory to another. Like VFO-A, one memory can be selectively copied; how­ever, there are a few differences.
To copy from one memory to another (including PMS memories), first activate memory tuning by simply turn­ing the VFO dial so that “M-TUNE” appears (and then tuning back to the desired frequency). Rotate the VRF/ MEM CH knob to select a memory to fill, then (within 3 seconds) press [AuM] to copy the contents from the re-tuned (source) memory to the destination memory.
GROUPING MEMORIES
The 99 regular memories and PMS memories P1~P9 can be grouped among up to five memory banks, if desired. Memory grouping is configured by menu selections 0-1 through 0-5.
By default, Group 1 is filled with all memories; Groups 2~5 are disabled (empty). Group 2 is enabled by not filling group 1 to capacity, and carrying over the extra memories, and so on. You could fill Group 1 with memories 1~20, for example, and carry over memo­ries 21~99 and P1~P9 to Group 2, or else you can apportion them among Groups 2~5, as desired. Re­member that to carry over memories from one group to the next, the preceding group must not be filled to capacity (i.e., the group holding memory channel P9 is the last enabled group).
Limiting Memory Group Operation
If you have assigned filled memories into more than one group (as explained on the previous page), you can enable a particular group and limit memory recall and scanning operation (covered later) only to those memories in that selected group, if so desired.
To do this, simply rotate the VRF/MEM CH knob so that any memory channel number in the desired group is displayed, then press the [M GRP] button just above and to the left (see box below). The “GROUP” indica­tor appears and you will find that only memories within that group are now available for recall and operation.
Notice
Regarding the VRF/MEM CH Knob
When the VRF feature is engaged, the VRF/MEM CH knob tunes the passband of the narrow input
“Preselector” filter. During Memory operation, to enable memory channel selection, press the VRF/ MEM CH knob momentarily; rotation of the knob will now allow you to select other memories. And if you want to enter the “Memory Tune” mode and step around in channelized steps (per the setting of menu selection 1-5), press and hold in the VRF/ MEM CH knob for ½ second.

RECALLING & OPERATING ON MEMORY CHANNELS
QMB (QUICK MEMORY BANK) OPERATION
The Quick Memory Bank is comprised of five memories (labeled C1 ~ C5) independent from the regular and PMS memories. These can quickly store operating parameters for later recall. You might find this handy to use when you have tuned a station of interest that you want to save, but don’t want to over­write your regular or PMS memories, especially if you have them organized a specific way.
You can use the QMB memories the same way you would a notepad in your shack - for jotting down (sav­ing) frequencies and modes to come back to later. There are five QMB memories enabled by default; how­ever you can disable some if desired, using menu se- lection 0-6.
r To store a frequency into the first Quick Memory
(
C-1), simply press [STO].
r Stored Quick Memories are recalled by pressing
[
RCL] repeatedly to select the desired memory
(“QMB” will be displayed at the left, and the Quick
Memory channel number will be displayed in the
memory box, as shown below).
Additional settings will be entered directly into C-1, with previously-stored entries then being shifted to the next available Quick Memory. This “stacking” system keeps the most recent entry in the first memory, and automatically shifts older entries into the next consecu­tive memory. After all Quick memories have been filled, additional entries overwrite previous ones on a “first­in, first-out” basis (as shown inside the box below).
r To revert from QMB operation back to VFO-A, sim-
ply press [VFO(MEM)] once.

Scanning Features
VFO SCANNING
You can start scanning on the Main VFO by holding the microphone UP or DWN button for ½ second (the receiver squelch does not have to be closed in this case). To increase the scan speed (x10) press either the microphone FST button (momentary-type) or the front panel [FAST] button. Scanning continues up or down until a button is pushed, or else “loops-around” when the upper or lower receiver limits are reached.
Scan speed is determined by the receiver “dwell time” using menu selection 2-4. Dwell time is the dura­tion that each channel is sampled for activity as the receiver scans up or down and is adjustable from 1 msec (fast) to 100 msec (slowest). Try experimenting with different durations until you reach the desired scan rate.
MEMORY SCANNING
The 99 memories in the MARK-V FT-1000MP of­fer some choices regarding how they are scanned, and, after the following brief description, you can decide how to tailor scanning for your operating needs.
When receiving on a recalled memory (with “MEM” displayed), you can scan all stored memories by just holding the microphone DWN or UP button for ½-sec­ond to start. If you want scanning to pause on signals, you must first adjust the SQL control to silence the receiver (green “MAIN BUSY” indicator off) on a clear channel. Scanning pauses on any channel having a signal strong enough to open the squelch, and the two decimal points in the frequency display blink. You may need to readjust the SQL control to prevent scanning from stopping on only background noise. Scan speed is not affected by the microphone or panel [FAST] but­tons, but is configured by menu selection 2-3 . The memory scanning “dwell time” is adjustable from 100 (fast) ~ 1000 msec (slow).
To stop scanning, press the PTT switch (no trans­mission will occur), or a microphone button again. When scanning, keep in mind that the IPO and ATT selections also affect the squelch threshold by chang­ing receiver front-end sensitivity.
Auto Memory Write
While scanning the VFO or a retuned memory, you can have the MARK-V FT-1000MP automatically write active channels into memories for later recall and scanning. As scanning pauses on activity, frequncy information is written into available memo­ries in Group 1, or all enabled groups, until full. You can leave scanning unattended, if desired, then return later to recall and check memories for atation activity.
To enable this feature, recall memu selection 2-5, and select GROUP 1, ALL GROUPS, or OFF. Fol­low the procedures outlined for VFO Scanning, Memory Tuning, and also review the descriptions for Scan Resume Modes. Remember that for scan­ning to stop on activity, the squelch must be closed.
MEMORY SCAN SKIP
By default, all programmed memories are included for scanning. However, you can “flag” some of them to be skipped while scanning. To do this, recall the memory you want to be skipped, and hold either the front panel or microphone [FAST] button while press­ing [M CK] momentarily so the “dash” between the group number and memory channel number disap­pears. If you have flagged a memory to be skipped, and later want to enable it again, just repeat the [FAST + [M CK] procedure.

Scanning Features
MEMORY SCANNING
MEMORY “MASKING
You may want to hide some memories from opera­tion, to simplify selection of others. To mask a displayed memory, while “MEM” is displayed, press and hold in [
AuM] for ½ second until the double beep sounds.
But be careful: if you do this instead while “M TUNE” is displayed - that is, after retuning the memory, the re­tuned data will overwrite the original memory data, but it will not be masked. So, if you have re-tuned the memory and don’t want to save the changes, cancel them first by pressing [VFO(MEM)] once, and then hold [
AuM] for ½ second. No frequency digits appear for
masked memories - just the two decimal points remain.
Masked memories are also skipped during scan­ning. If you don’t overwrite a masked memory, you can unmask it simply by repeating the same procedure you used to mask it.
SCAN SKIP DISABLE
After programming many memories, you may have tagged specific ones to be skipped during scanning. Should you later change your mind and want to scan all of them again, you don’t have to go back and re­enable each tagged one (there’s an easier way!).
Recall menu selection 2-6 and change the “Scan All” setting from off to on. The memory tags are still re­tained, but ignored when this setting is turned on. To return to selective scanning, simply change the setting to “Off.”
SCAN RESUME MODE
There are three choices that determine how scan­ning will respond when activity is detected. Scan re­sume operation is configured by recalling menu selec- tion 2-1, and choosing the desired mode. Below is an outline of each scan resume mode and how it oper­ates.
Carrier Stop (default) - With the squelch closed, scanning pauses on signal activity, then resumes soon after the carrier disappears. With the squelch open, scanning will not continue unless the receiver is qui­eted again (SQL control).
Carrier Timed Stop - With the squelch closed, scanning pauses on activity, then resumes automati­cally after a preset duration (5 seconds by default), whether signal activity remains or not (time- delay re­sume).
Carrier Timed Slow - With the squelch closed, scanning slows down (but doesn’t stop) for a preset duration (5 seconds by default), when activity is de­tected.
For the Timed Stop and Timed Slow modes, the pause duration can be set between 1 and 10 seconds with menu selection 2-7, or the scan pause (resume) feature can be disabled completely using menu selec- tion 2-0. If disabled, scanning will not stop for any ac­tivity.

PROGRAMMED MEMORY SCANNING PMS MEMORIES P1 ~ P9
To limit scanning (or tuning) to within a particular frequency range, you can use Programmed Memory Scanning (PMS) provided with nine special-purpose memories (P1 ~ P9). First, store the upper and lower frequency limits of the range in a consecutive pair of PMS memories (i.e., P1 & P2, P2 & P3, etc). For ex­ample, P2 might contain the lower edge and P3 the upper. Next recall the first memory of the pair that hold the range you want to scan or tune, then nudge the main VFO knob to activate memory tuning (“PRGM” appears). Tuning and scanning are now within the lim­its of the selected PMS memory pair, keeping opera­tion inside this programmed range.
Example: Limit tuning and scanning to the 17-m ama­teur band’s limits.
r Press [VFO(MEM)] as necessary, to display “VFO.”
Tune to the low edge of the 17-m band: 18.068 MHz,
and select the desired mode (here, USB or CW). r Rotate the VRF/MEM CH knob , and select memory
P1. Then (while “MCK” is still blinking) hold in the
[
AuM] key for ½ second to write the VFO’s fre-
quency into P1.
Scanning Features
r Press [VFO(MEM)] to select the VFO, and now tune
to the high edge of the 17-m band (18.168 MHz). Be sure that the operating mode has not changed.
r Rotate the VRF/MEM CH knob, then select memory
P2. Hold in the [AuM] key for ½ second to write the VFO’s frequency into P2.
r Now recall memory P1, and turn the tuning knob
slightly (to activate memory tuning).
Tuning and scanning are now limited to the 18.068­to 18.168-MHz range until you press [VFO(MEM)] to return to memory channel or VFO operation. During PMS operation, you can also press (and hold in) [AuM to copy the displayed frequency to a memory, or [MuA to write the displayed frequency to a VFO.
Notice
Regarding the VRF/MEM CH Knob
When the VRF feature is engaged, the VRF/MEM CH knob tunes the passband of the narrow input
“Preselector” filter. During Memory operation, to enable memory channel selection, press the VRF/ MEM CH knob momentarily; rotation of the knob will now allow you to select other memories.

Advanced Features
Enhanced Digital Signal Processing uses A/D (Ana­log to Digital) and D/A (Digital to Analog) conversion techniques under microprocessor control to achieve significant enhancement of signals at the audio and low-frequency IF levels. The major capabilities offered by EDSP lie in the area of heterodyne/random noise reduction and audio bandpass filtering. Digital filters have many advantages over their analog counterparts in that they can meet tighter specifications on param­eters such as voltage and temperature drift and noise problems. And the hybrid filter architecture of the MARK-V FT-1000MP, utilizing extensive analog IF fil­tering to protect the DSP circuitry which follows, guar­antees superior strong-signal performance under crowded band conditions.
The MARK-V FT-1000MP uses a 16-bit NEC µPD77016 CMOS digital signal processor chip featur­ing a 30-nS Instructions Cycle, 33 MHz Clock fre­quency, a 16 x 16-bit and 40-bit multiply accumulator, 40-bit Barrel Shifter, and 64 K Bytes Program ROM.
DSP enhancement is basically a four-step process. Audio (or EDSP IF) input is sampled several thousands of times per second, then the frequency and ampli­tude of the audio are converted into a digital represen­tation of the analog waveform that resembles ascend­ing and descending “staircases” by the A/D (analog­to-digital) converter. This is later changed into digital serial bitstream as raw data for analysis and process­ing.
EDSP
Information is extracted from digital data, and the EDSP chip performs complex mathematical calcula­tions according to pre-programmed routines known as algorithms. Algorithms are processed then compared against a set of parameters (or threshold if you will) based on a phenomenon known as “correlation.” The degree of correlation depends on the incoming signal’s characteristics: random noise has relatively little cor­relation, speech contains moderate correlation, with heterodynes (and QRM) being highly correlated. The EDSP microprocessor is programmed with various parameters corresponding to different known audio phenomena.
EDSP allows the frequency spectrum of a received signal to be modified according to a specific set of pa­rameters for the desired effect (QRM reduction, audio tailoring, etc.). Certain types of audio interference leave a distinctive signature or “footprint,” which can be rec­ognized, and “processed out” of the digitally-recon­structed audio from the EDSP chip. Also, digital filters are constructed which emulate traditional low-pass, high-pass, band-pass, and band-stop filters, except with steep skirt shaping and performance possible with digi­tal technology. EDSP also allows direct “digital” de­modulation of audio for receive, as well as direct modu­lation of audio for transmit.

EDSP
EDSP FUNCTIONS
The EDSP circuitry in the MARK-V FT-1000MP al­lows digital enhancement of both transmitted and re­ceived audio. A basic primer on DSP was given to in­form you more about this capability than just the panel label and button location. Now you can customize its filtering capabilities and use it to reduce QRM and tai­lor audio response for each operating mode.
EDSP Modulation
TX Audio Enhancement (Menu 4-4)
Four microphone audio responses can be chosen using menu selection 4-4. Since voice audio character­istics vary between people, these settings enable tai­loring your transmitted audio for best clarity.
TX IF Filter Selection (Menu 5-9)
Normally, 2.4 kHz filters are selected for both the 455 kHz and 8.2 MHz Tx IF. However, with EDSP op­eration, you can keep the 2.4 kHz filter, or select the
6.0 kHz filter for maximum bandwidth and better fre­quency response on your transmitted audio. The re­sulting effect of this filter selection is directly related to menu selection 7-7 (below). The desired filter is chosen with menu selection 5-9, and is only active when EDSP is turned on. Note that your signal’s actual bandwidth on SSB will not exceed that set by the IF analog filter, with a (-6 dB) bandwidth of approximately 2.4 kHz be­ing typical.
EDSP Modulation/Demodulation (Menu 7-7)
TX EDSP Modulation - Early-stage transmitted SSB audio may be applied directly to the EDSP cir­cuitry for processing, bypassing the analog modulator. EDSP filter parameters can be matched to voice char­acteristics for optimum audio tailoring.
RX EDSP Demodulation - For SSB, CW and AM, receiver 3rd IF output is applied directly to EDSP cir­cuitry for demodulation and processing, bypassing the analog product detector. Reduced noise is a primary benefit of the EDSP Demodulator, which may be used alone or in conjunction with EDSP filtering.
Menu selection 7-7 configures the settings for both the RX and TX EDSP modulation circuits (see table at the right). Note also that if the EDSP is turned off via menu selection 0-9, these circuits will revert to their ana­log counterparts.
EDSP RX AUDIO ENHANCEMENT
EDSP Contours
QRM reduction is accomplished by uti­lization of the various DSP filter networks. The front CONTOUR buttons select Low­( button,) Mid- ( button,) and High­cut ( button) filters, along with a band pass filter selection (see below).
The low-, mid-, and high-cut filters are pre-set for different audio emphasis, using mathematical algorithms developed after thousands of hours of on-the-air testing. The bandpass filter, activated when the [IDBT] button on the Shuttle Jog is pressed, is automatically pro­grammed to match the analog IF passband established by the setting of the WIDTH and SHIFT controls. No manual sdjustment is required.
This CONTOUR LED indicates the current status of the EDSP Contour feature:
Glowing Green: Low-cut filter selected,
Glowing Orange: Mid-cut filter selected,
Glowing Red: High-cut filter selected,
Off: EDSP Contour Off.
In actual operation, it may be very difficult to “pre­dict” which Contour response will best enhance the sig­nal-to-noise recovery. So under difficult conditions, you should change selections often; don’t be surprised if one selection suddenly causes the incoming signal to “jump” out of the background noise.

EDSP NOISE REDUCER
Noise reduction is accomplished by utilization of one of the four set­tings selected by the front panel [NR button. Press the [NR] button to toggle between Noise Reduction “A,” “B,”C,” “D,” and “OFF.” Each setting has correlation parameters optimized to reduce random noise, static, pulse/ man-made noise and heterodynes, with little degradation of the desired signal. As with the Contour feature, it is difficult to predict which setting will be most effective under current noise conditions, so experiment with the settings as conditions change.
EDSP APF (AUDIO PEAK FILTER
In the CW mode, the front [APF button sets the bandwidth of the EDSP’s CW peaking filter. Press the [
APF] button repeatedly to toggle be-
tween bandwidth selections “240 Hz,” “120 Hz,” “60 Hz,” “DATA” (which is optimized bandwidth for FAX, PACKET or SSTV operation), and “OFF.”

EDSP AUTO M ULTIPLE NOTCH FILTER
On page 48, we previously discussed basic IF notch filter operation and how it is used to attenuate hetero­dynes. EDSP offers multiple-notch capability within the AF (rather than IF) bandpass with the press of a but­ton. With the conventional (455 kHz 3rd IF) notch filter, by comparison, only a single offending heterodyne at a time can be attenuated by pressing the [NOTCH] but­ton and slowly rotating the NOTCH control. Notch tun­ing can sometimes be critical, as you have to position the control for maximum “depth” by ear.
With the multiple notch, the EDSP circuitry exam­ines the AF bandpass and the correlation of the sig­nals present. After correlation parameters are com­pared, unmodulated signals (heterodynes) are identi­fied and notched out. As EDSP dynamically checks the audio, new heterodynes will be identified and notched, one by one, as they appear. See the illustra­tion below.
Theoretically, an infinite amount of notches could be inserted to attenuate each new heterodyne; how­ever, the total notch bandwidth would approach that of the audio passband, and, progressively notch all au­dio. One limitation of the EDSP auto multiple notch fea­ture is that it is only for use with SSB modes; attempt­ing to use it on CW would cause the CW signals to disappear - not the desired function of a CW filter!
IDBT
(
INTERLOCKED DIGITAL BANDWIDTH TRACKING) SYSTEM
You can control the EDSP Contour’s “Bandpass” filter characteristics according to the SHIFT and WIDTH knobs’ settings. To do this, press the [IDBT] button on the right side of the Shuttle Jog to activate the IDBS feature. Doing so will automatically program the band­width of the Bandpass Contour filter to match the IF bandwidth set by these two controls; therefore, if you have narrowed the IF passband to 1.9 kHz using the WIDTH and SHIFT controls, the IDBT feature will au­tomatically set the Contour filter’s Bandpass mode to
1.9 kHz, as well.
The effect of the EDSP notch filter will not be ob­served on the S-meter, as the EDSP is outside of the AGC circuit’s loop. The manual IF notch, however, is within the AGC loop, so you should use the IF notch for particularly strong interference sources.
EDSP Auto Multiple Notch Action
page 74 MARK-V FT-1000MP Operating Manual
The two Notch circuits may be enabled and/or dis­abled using menu selection 2-9. It is important to take note of the selection options available:
IF NOTCH - Manual IF notch operation using the front panel knob with the same name. The EDSP notch is not accessible in this mode.
AUTO DSP - When EDSP is engaged (the green “EDSP” LED is lit), the [NOTCH] button serves as an On/Off switch for the EDSP auto-notch filter. The EDSP notch filter automatically locates existing heterodynes and notches them out. Any additional heterodynes are also notched as they appear. The IF Notch is acces­sible only when the EDSP is turned off.
SELECT - If EDSP is engaged (menu selection 0-9 not set to “off”), and the [NOTCH] button is pressed, both the EDSP Auto-Notch and IF notch operation take effect simultaneously. If EDSP were disabled via menu selection 0-9, the IF Notch will still be available.

Important Note About EDSP
An advantage of EDSP is the flexibility for the user to customize or “tailor” received and transmitted audio. Menu selections 4-4, 5-9, and 7-7 each have distinct effects on the sound of your transmitted audio. The “ultimate” combination of these settings will of course vary between users personal taste, and for the desired effect (distinctive audio, QRM penetration, etc.).
The easiest way to immediately hear the effect of different EDSP settings is to use the transceiver’s built-in MONITOR circuit to listen to your audio while transmitting. In this way, you can step through the various setting combinations, and select the ones that appeal the most to you, or the receiving sta­tion.
Note that there is a “short-cut” available, affording easy access to menu selection 2-9. Just press and hold in the [FAST] key, and press the [NOTCH] button.

REMOTE CONTROL OPERATION
INTRODUCTION
You can select and activate various transceiver func-
tions via the optional FH-1 Remote Control Keypad (available from your Yaesu dealer) connected to the REMOTE jack on the rear panel of the transceiver.
Four transceiver remote control features are avail-
able via menu selection 7-9. Once the desired remote control operating mode is selected, pressing a key activates one of the functions available in that operat­ing mode; the function activated by a key closure might be a CW message playback, a contest number being incremented upward, or a front panel function being duplicated.
The four remote control features available are: I. Contest Memory Keyer - The recording and play-
back of repetitive contest messages are accom­plished via the keypad.
II. VFO/Memory Function Control - In this mode, the
remote control keypad duplicates the front panel keys that relate to VFO/Memory selection and pro­gramming.
III. Main VFO-A Control - In this mode, the remote
control keypad duplicates the functions of the front panel BAND keypad (keys “0” ~ “9”), plus [SUB(CE and [ENT]) as applied to the Main VFO.
IV. Sub VFO B Control - Same as above, except key-
pad inputs are applied to the Sub VFO.
I. CONTEST KEYER CONTROL
The MARK-V FT-1000MP includes a contest memory keyer which includes a number of automated features which reduce operator fatigue during long hours of contest operating.
Features
The keyer offers six CW message memories that can be used to store your callsign and/or repetitive messages like “CQ TEST DE <callsign>” or “TU QRZ <callsign>.” Additionally, a three- or four-digit contest
serial number “001, 002....” may be imbedded into the
first memory location for contest exchange use. The contest number can be incremented/decremented manually, reset to an arbitrary number (in the middle of a contest), and can also be played back using “cut” numbers (“5NN TT1, 5NN TT2...”), if desired.
Linear amplifier or external antenna tuner adjust­ment may also be assisted, thanks to the momentary [
TUNE] key on the keypad. Via menu selection 4-3, the
tune-up power output may be limited to a maximum of 50 or 10 Watts, instead of the usual 200 Watts, and the [TUNE] then serves as a momentary (push and hold) key which activates the transmitter and puts out
)]
a carrier for tuning purposes.
Let’s now look at the storage and recall capabilities of the contest memory keyer.
The features and programming techniques for the remote control features are discussed below, begin­ning with the contest memory keyer.
page 76 MARK-V FT-1000MP Operating Manual
REMOTE CONTROL OPERATION
1. Contest Number Memory
The [#] key allows storage of a message of up to 20 characters in length. Within this message, a con­test sequential serial number may be imbedded dur­ing the programming process by sending “???” (three Question Marks) in the place where the contest num­ber is desired. The Question Marks should be sepa­rated only by a letter space, not by a word space. Thus, to send “5NN 001, 5NN 002,” and so forth, you send “5NN ???” (not “5NN ? ? ?”) during memory storage.
Advanced Features
To select between three-digit contest numbers (e.g. “599001”) and four digit contest numbers (e.g. “5991234”), select menu selection 7-6, then rotate the Sub Dial to the final selection, which is the number of playback digits. Select the desired number of digits, then press [ENT] to save the setting and exit. Note that, if you begin with a three-digit contest number, the MARK-V FT-1000MP will automatically switch over to four-digit numbering after QSO #999, so it generally is best to select three-digit numbering.
A contest number may only be imbedded in the
memory location activated by [#] key.
You can manually increment or decrement the num­ber (in case you need to repeat or “catch up” to the correct contest number) by pushing the [#UP] key to increment, or the [#DWN] key to decrement.
To reset an arbitrary contest number (in the middle of the contest, when you may have been using a differ­ent transceiver on a different band, for example), se­lect menu selection 7-3. Now rotate the Main Dial to se­lect the next-to-be-used contest number, and press [
ENT] to save your new number and exit.
To abbreviate certain numbers in the contest ex­change, select menu selection 7-6. In this Menu area, substitutions of Morse letters for (longer) numbers can be accomplished. For example, the keyer may be com­manded to send “T” for “Zero,” “A” for “One,” “U” for “Two,” and “N” for “Nine” while leaving all other num­bers in their normal (longer) formats.
See the chart below for details of the selections available.
2. CQ or ID Memory
The [ID] key allows storage and recall of any mes­sage of up to 20 characters in length. Because of the convenient location of [ID] key on the FH-1 Remote Control Keypad option, this memory location is most ideally suitable for your main “CQ TEST” message or for your callsign (for one-touch use in a pile-up, for example).
3. User Message Memories 1 - 4
Keys [CH 1] ~ [CH 4] allow storage and recall of messages of up to 50 characters in length. These memory locations are more suitable for longer mes­sages which cannot be programmed into the “Contest Number” or “ID” memory locations.
4. Message Storage
The [STO] key is used in the message memoriza­tion process. Push [STO] followed by one of the mes­sage playback keys ([#], [ID], or [CH 1] ~ [CH 4]), then send (on your keyer paddle) the message to be stored, then press the [STO] key to terminate the memory stor­age process.

5. Message Monitor (Playback without Transmitting)
The [MONI] key may be used to review the con-
tents of a memory location, or to determine the next­to-be-used contest number, without transmitting the message over the air.
To use this feature, the [MONI] key on the front panel
of the transceiver must be turned off. The reason for this is that the [MONI] key activates the RF keying moni­tor, which requires a transmitted signal in order to func­tion.
To check the contents of the “ID” memory slot, for
example, press [MONI] then [ID]. You will hear the message which currently is stored in the “ID” slot in the speaker or headphones. To check to see what the next-to-be-sent contest number is (in case you’ve for­gotten, etc.), press [MONI] then [#]. The contents of the “#” memory slot will be played (e.g. “599388 BK”), and the contest number will not increment after play-
page 77MARK-V FT-1000MP Operating Manual

REMOTE CONTROL OPERATION
back in this mode; the contest number only increments if the message is sent over the air.
Remember, if pressing the [MONI] key, then a memory playback key, has no effect, you probably have the [MONI] button pushed in. De-activate the RF key­ing monitor to allow yourself to hear the stored mes­sage.
6. Tune Mode
Pressing the [TUNE] key activates a transmitted carrier for as long as the key is held in; this is useful for adjustment of a linear amplifier or external antenna tuner, or for antenna performance comparisons over the air.
The power output level to be used for tuning is pro­grammable via menu selection 4-3. In this Menu selec­tion, maximum power output levels of 10W, 50W, or 200W may be chosen. The front panel RF PWR con­trol allows adjustment of the power level up to the maxi­mum power output selected via menu selection 4-3.
Contest Keyer Operation
Programming of the six available message storage locations is accomplished by a simple keyed and keyer paddle input sequence. Only Iambic (not “Bug”) key­ing can be used for storage of CW messages, and we recommend that menu selection 7-0 be set to “Iambic 2” during message storage, although you may prefer to use “Iambic 1” during manual sending once the de­sired messages are stored.
Example: Program “CQ TEST DX1DX DX1DX” into the “ID” Memory Slot.
r Be sure that the FH-1 (or your home-built) keypad
is plugged into the rear panel REMOTE jack. r Press the [STO] key, followed by [ID]. This selects
the “ID” memory as the memory location to be uti-
lized. r Using your keyer paddle, send “CQ TEST DX1DX
DX1DX” followed by another press of key [STO] to
end the storage process for this memory location.
Be careful to pause slightly after each word so as
to leave a word space in the message string. r To play back the message memory without trans-
mitting, press the [MONI] key followed next by [ID].
If you don’t hear anything, check to be sure that the
MONI” LED on the bottom-left-hand edge of the
BOWMAN front panel is not illuminated. r To transmit the CQ message, just press [ID].
Message memories 1 ~ 4 (keys [CH 1] ~ [CH 4]) are programmed, played back, and transmitted in the same manner; however, you can enter up to 50 char­acters in each of these. Particularly if you have a long callsign, you may wish to use key [ID] for storage of
just your callsign, then use message memories 1 ~ 4 (keys [CH 1] ~ [CH 4]) for your “CQ Contest” mes­sages.
Note also that if you want to send a message mul­tiple times, you can press the playback key more than once; at the end of the first message segment, the message will restart and be sent again. This is useful if you want to call “CQ” while getting a drink from the refrigerator.
You may then send a “K” manually when the auto­matic message generation is completed after the de­sired number of repeats.
Example: Program “599001 BK” as an initial contest number (to be incremented after each QSO):
r Following the procedure described above, press the
[
STO] key then the [#] key.
r Now send the contest exchange, but send “???” at
the point in the message where you want the num-
ber to appear. In this example, send “599??? BK”
then press [STO] to terminate the entry. To send
“5NN001 BK” (“N” replacing “9”), modify your send-
ing accordingly (the number-cutting protocol in menu
selection 7-6 only affects numbers sent within the
“???” area). If you want to separate the signal re-
port and the contest number, send “5NN ??? BK”
(add a word space between the report and the ques-
tion marks). r To play back the just-stored message without trans-
mitting, and without causing the contest number to
increment automatically, press the [MONI] key fol-
lowed by [#] key. You may do this as many times as
you want and the contest number will stay the same.
If you transmit the message by pressing the [#] key
alone, however, the contest number will automati-
cally increment, and another press of the [#] key
will cause “599002 BK” to be sent (followed by
“599003 BK” the following time, and so forth). r If the other station asks for a repeat of your contest
exchange, remember that the number will have
incremented automatically after you sent it. Press
the [DWN] key to return to the previous number,
then press [#] key to repeat the exchange for the
other station. If you need to increment the number
manually for some reason, the [#UP] key may be
used in the same manner. r If, for some reason, the contest number generated
via [#] key is significantly different from the desired
number, it may be reset via menu selection 7-3. From
this menu selection, you may set the next-to-be-
used contest number to any value between 0000
and 9999 by rotating the Main Dial; press [ENT] to
save the new setting and exit.

II. VFO/MEMORY CONTROL
Menu selection 7-9 also allows utilization of the Re­mote Control Keypad for VFO and Memory control. The front panel [VFO(MEM)], [AuB], [A
CK], [AuM], [RCL], [STO] and [DUAL] keys, and VRF/ MEM CH knob are duplicated on the Remote Control
Keypad.
III. MAIN VFO-A CONTROL
Selection of this mode via menu selection 7-9 dupli­cates the action of the 12-key front panel BAND key­pad on the front panel of the MARK-V FT-1000MP. Direct frequency entry and one-touch band change are possible on both the Main and Sub VFOs, exactly as on the front panel keypad.
IV. SUB VFO-B CONTROL
This function is essentially identical to “Main VFO­A Control” as described above. However, when the
[
ENT] key is pushed to begin direct frequency entry,
the frequency input will be applied to the Sub VFO-B register, not the Main VFO-A register. This allows the operator to use the transceiver’s front panel keypad for the Main VFO, and the remote keypad for the Sub VFO, thus reducing the required keystrokes by one.

Advanced Features
Note that, in the Sub VFO-B Control mode, push­ing [SUB(CE)] then [ENT] does not shift frequency en­try control to the Main VFO-A (which is the “sub” VFO of Sub VFO-B). In this mode, frequency can only be applied to the Sub VFO-B; there is no direct frequency entry pathway to Main VFO-A.

USER-CUSTOMIZED OPERATING M ODE
OVERVIEW
This mode recalls a pre-configured operating “en-
vironment” (mode, filter selections, offsets, etc.) by pressing and hold in the [PKT] key on the front panel.
This can be useful for storing your favorite combi-
nation of operational settings for a mode you often use. Digital operators who go through the various proce­dures of combining filter selections, carrier and dis­play offsets, etc., for a custom environment optimized for FAX or SSTV (as an example) can store these set­tings for easy recall. For special modes that require unique configuration of transceiver settings that are not used elsewhere, the “USER” mode comes in handy for storing these parameters while keeping other trans­ceiver settings default for general operation.
The following parameters are user-customized by
recalling menu selection 8-6. Operating parameters are chosen by turning the SUB VFO-B tuning knob, while parameter settings are changed with the MAIN VFO-A knob (see below).

Note: see pages 106 and 107 for a complete listing of default settings according to operating mode.
Important!
While the “USER” Mode allows customizing op­eration for various operating environments, chang­ing some settings (especially the PLL offset and carrier injection) can adversely affect transceiver operation. Before making any “USER” Mode ad­justments, ensure you have a firm understanding on how changing these affect transceiver opera­tion and frequency display. If you are not sure, we recommend leaving them as set (to their default values shown in the table).
You can return all transceiver settings (menu se­lections) to their default values at any time by per­forming a CPU reset. Simply hold the [SUB(CE)], [29(0)] transceiver on.

OPTIONAL DVS-2 DIGITAL VOICE RECORDER
OVERVIEW
The DVS-2 is a digital voice recorder designed es­pecially for SSB, AM, and FM operation with newer model Yaesu transceivers having a special jack for connection of the DVS-2 on the rear panel. It offers two independent functions:
r Recording received signals for playback later in
the loudspeaker or headphone;
r Recording signals, using the microphone,for
playback over the air (during transmission).
Each mode uses its own memory, so both modes can be used to retain data at the same time. Operating details are provided with the DVS-2, but a summary is provided here.
INSTALLATION
Connect the DVS-2 cable to the DVS-2 jack on the rear of the transceiver. You must also have a micro­phone connected to the MIC jack on the front panel of the transceiver to record your voice for transmissions.

MESSAGE RECORDING
(FROM MAIN OR SUB RECEIVER AUDIO)
When used in this mode, the DVS-2 maintains a continuous recording of the last (approximately) 16 seconds of audio from either the main or sub-receiver. This can be particularly helpful in picking out callsigns during a pileup, as you can replay the same recording as often as you like (until you record over it). The record/ playback process in this mode is analogous to an 16­second “endless tape” - that is, you can turn the re­corder on and off to record up to a total of 16 seconds of small segments of audio, or you can leave the re­corder running to get one 16-second segment. In any case, the recorder overwrites data more than 16 (re­cording) seconds old.
r To start the receiver recorder, just press the [REC
button. The yellow “REC” LED will light (and stay
lit). r When you hear something you want to play back,
press the [STOP] button (the “REC” LED will turn
off), and then press the [PLAY] button. Now the
green “PLAY” LED will light as recorded audio is
played back through the main receiver audio chan-
nel.
Note that if you record for less than 16 seconds, playback will start at the point you first started record­ing (no “rewind” necessary). However, if you record for more than 16 seconds, playback will begin at the point 16 seconds before you stopped recording. In either case, playback will repeat any recorded audio every 16 seconds.
PLAYBACK
(
ON THE AIR OF RECORDED RECEIVER AUDIO
Once you have recorded an incoming transmission from another station, you can play it back to them by pressing the [PLAY] button on the DVS-2, followed im­mediately by the MOX switch on the front panel of the MARK-V FT-1000MP. This can be handy if you wish to advise another station of an anomalous signal condi­tion, for example.
Note: Communications-privacy regulations may re­quire you not to divulge the results of a prior contact (or a receiving session) to a third party. Consult the regulations for your country to ensure full compliance with your countries regulations.

MESSAGE RECORDING
(
FROM MICROPHONE AUDIO
This mode allows the DVS-2 to record either two 8­second messages or four 4-second messages of au­dio from the microphone, such as contest exchanges or station IDs. Each can then be played back, either in monitor mode (without transmission), or directly over the air. Note that the digital memory used in this mode is independent from that used for receiver recording (so you can store both types of memory without inter­fering with one another).
The 8- and 4-second messages share the same memory, so two 4-second message segments (1 and 2 or 3 and 4) can be combined into one 8-second mes­sage for transmission, as indicated in the following table.

r Get your microphone ready, and then press the
[
MEMO] button (the yellow “REC” LED will blink).
r Now press the numbered key for the segment (or
segment pair) to record (only [1] or [2] for the 8­second mode), and start talking (do not press the PTT switch unless you want to transmit at the same time you are recording).
The “REC” LED will stop blinking and stay on for the recording period (4 or 8 seconds), and then turn off. Also, the red LED above the numbered key you pressed will come on (if this segment was previously empty) and stay on, indicating this segment is now stor­ing data.
To stop recording at any point before the selected segment’s time limit is up, simply press STOP.
This is the preferred method, since it eliminates any “dead time” remaining from your last-recorded word and end of the time segment (which would keep your transmitter unnecessarily keyed for a short period). In any case, your message can not exceed the 4- or 8­second limit.

MESSAGE TRANSMISSION
(
“ON THE AIR•EP LAYBACK
After recording a memory segment, you can play it back over the air by pressing the appropriate numbered button. The green “PLAY” and red “TX” LEDs will both light for a maximum of either four or eight seconds, according to the setting of the MESSAGE MODE switch.
Note! Normally, pressing a numbered message key on the DVS-2 activates the MARK-V FT-1000MP transmitter and sends the recorded message. If you would like to disable PTT control from the DVS-2, re­call menu selection 4-7 and change the setting to “OFF.” Now, transmission is only possible using the micro­phone PTT or MOX switches.
)
Don’t worry if you didn’t have enough time to finish your phrase, you can repeat the above steps to re­record the same message - the previous message will be overwritten (note that there is no “rewind” step re­quired).
MESSAGE MONITOR
(
PLA YBACK WITHOUT TRANSMITTING
You can check the contents of a memory segment or pair without playing it back over the air, just by press­ing [MONI] followed by the appropriate numbered key.
The green “REC” LED blinks until you press the numbered key, and then stays on during the playback period. We recommend always using this to check the results immediately after making a recording and be­fore playing it back over the air. If you have recorded several 4-second segments that you intend to com­bine during playback, move the MESSAGE MODE switch to the [2 x 8 SEC] position to hear how the seg­ments sound when played back together. Note from the table on the preceding page that, in the 8-second mode, the [1] button plays back segments 1 and 2, while the [2] button plays back segments 3 and 4.
)
Receiver Recording with the
MARK-V FT-1000MP
As the DVS-2 uses only one receiver audio chan­nel of the MARK-V FT-1000MP, you can play back recordings without missing real-time action by pressing [AuB] to set the two VFOs to the same frequency.
With stereo headphones, this allows you to con­tinually monitor signals on the sub VFO audio chan­nel while playing back recording on the main chan­nel.
Selecting Receiver Audio
As mentioned earlier, the DVS-2 can record audio from either the Main or Sub receiver. To choose the desired receiver, recall memory selection 4-6 and pick either MAIN VFO or SUB VFO as the default receiver.

PHONE PATCH OPERATION
OVERVIEW
Phone patch operation allows linking your MARK-
V FT-1000MP to the public telephone line to provide
two-way simplex communications for MARS operation, or on behalf of a third parties. The MARK-V FT-1000MP may be used with the LL-7 phone patch unit installed in the optional SP-8 external loudspeaker, or with phone patch units from other manufacturers. The diagram at the bottom of the page shows interconnection for the SP-8/LL-7 combination; be sure to consult the docu­mentation provided with units of other manufacture for installation instructions.
OPERATION
Phone patch Tx/Rx switching may be done manu-
ally using the PTT method, or automatically using the VOX circuit of the transceiver. While the PTT method does not require balancing the bridge circuit in the LL- 7, it does require more work by the operator: switching the microphone PTT or transceiver MOX button at each “over” during patched conversations. Therefore, most operators prefer to use the VOX method whenever the telephone signal-to-noise level permits. If the telephone noise level is high, however, the PTT method may still be necessary, so you should become familiar with both methods.
Regardless of which patch control method is used, you may need to instruct the person on the telephone to speak slowly at a clear normal voice, and to say “over” and then keep quiet when they expect a response from the other radio station. This serves as a notice to you (if you are using PTT control) to switch to receive while signaling the other station to go ahead and trans­mit, and will help avoid “doubling” with the other sta­tion.
During all phone patch operation you should moni­tor both sides of the conversation at all times (this may be required by law). This requires a telephone at the operating position.
Refer to the LL-7 Instruction Sheet for further de­tails on phone patch setup and operation.
Note
You may need to contact your telephone company for permission to connect another device to the phone circuit. Also, you should use a proper 600 Ohm, three-way transformer if connecting the LL- 7 with a telephone set to the same phone line.

TUNING METER RE-CALIBRATION
The multi-function meter offers either flashing single or dual segments to indicate properly tuned CW or FSK (RTTY/PKT) stations. An explanation of tuning indica­tions is on page 42.
CW TUNING
From the factory, the single CW tuning segment is calibrated (centered) for the default CW Pitch setting of 700 Hz. If you change the CW Pitch (page 56) to other than 700 Hz, you should re-calibrate the meter so that station center-tuning will match the new CW Pitch. Calibration is a simple process, and only requires a small Phillips screwdriver:
CW Tuning Meter Calibration
(after CW Pitch adjustment) r Open the access panel on the transceiver top case
to expose the ALC Unit. r After setting the desired CW Pitch, press the [SPOT
button to toggle the CW spot tone (which matches
the CW Pitch) on. Use a small screwdriver to slowly
turn CW control in the top access panel so the cen-
ter meter tuning segment turns on. r This completes the calibration for CW tuning; re-
place the panel, and turn off the spot tone.
Advanced Features
PACKET TUNING
The dual packet tuning segments are calibrated (centered) to the default 200-Hz shift tones used for 300-baud HF packet. These tones use a mark/space pair of 2025/2225 Hz. If you change the default PKT tones (menu selection 6-5) to other than 2025/2225 Hz, you should re-calibrate the meter so that mark/space tuning segments will match the new tone pair:
PKT Tuning Meter Calibration
(after changing PKT Tones) r Open the access panel on the transceiver top case
to expose the ALC Unit.
r After selecting the desired tone pair, recall menu
selection 4-2, and select “bEEP-tun” using the SUB
VFO-B knob.
r Rotate the MAIN VFO-A knob to display (and oscil-
late) the center frequency of the mark/space tone
]
pair you are using (1170 Hz, 1700 Hz, 2125 Hz,
2210 Hz - see page 58). r Use a small screwdriver to slowly turn PKT control
in the top access panel so the center meter tuning
segment turns on.
This completes the PKT calibration, replace the panel, and turn off the beep tone.
RTTY TUNING
RTTY tuning segments are calibrated (centered) for default 170-Hz shift, using a mark/space pair of 2125/ 2295 Hz. If you change the default RTTY shift (menu selection 6-0) to other than 170 Hz, you should re-cali­brate the meter so that mark/space tuning segments match the new tone pair:
RTTY Tuning Meter Calibration
(after changing RTTY Shift) r Open the access panel on the transceiver top case
to expose the ALC Unit.
r After setting the desired RTTY shift, recall menu
selection 4-2, and select “bEEP-tun” using the SUB
VFO-B tuning knob.
r Rotate the MAIN VFO-A knob to display (and oscil-
late) the center frequency of the mark/space tone
pair for the shift you are using (170 Hz = 2210 Hz,
425 Hz = 2125 Hz, 850 Hz = 2550 Hz). r Use a small screwdriver to slowly turn RTTY con-
trol in the top access panel so the center meter tun-
ing segment turns on.
This completes the RTTY calibration, replace the panel, and turn off the beep tone.
Caution!
Do not adjust TUM-M control in the top access panel by mistake, as this will adversely affect meter tuning indication, requiring factory re-alignment!

CAT System Computer Control
OVERVIEW
The CAT (Computer Aided Transceiver) System
in the MARK-V FT-1000MP provides control of fre­quency, VFO, memory, and other settings such as dual­channel memories and diversity reception using an external personal computer. This allows multiple con­trol operations to be fully automated as single mouse clicks or keystroke operations on the computer key­board.
The MARK-V FT-1000MP has a built-in level con-
verter, allowing direct connection from the rear-panel CAT jack to the serial port of your computer without the need of any external boxes.
Each time a command instruction is being received
from the computer via the CAT port, the “CAT ” indi­cator appears in the display, then turns off afterward. You will need a serial cable for connection to the RS­232C (serial or COM port) connector on your computer. Purchase a standard serial cable (not the so-called "null modem" type), ensuring it has the correct gender and number of pins (some serial COM port connectors use a 9-pin rather than 25-pin configuration). If your com­puter uses a custom connector, you may have to con­struct the cable. In this case, refer to the technical docu­mentation supplied with your computer for correct data connection.
Yaesu Musen does not produce CAT System op-
erating software due to the wide variety of personal computers and operating systems in use today. How­ever, the information provided in this chapter explains the serial data structure and opcodes used by the CAT system. This information, along with the short program­ming examples, is intended to help you start writing programs on your own. As you become more familiar with CAT operation, you can customize programs later on for your operating needs and discover the true op­erating potential of this system.
There are some commercially produced software
packages available, as well as various shareware and freeware programs. To find out more information, con­tact your dealer or check advertisements in current amateur radio journals and publications. Other valu­able information sources include amateur radio and PC users-groups, packet radio and PC bulletin boards (BBS), and amateur radio hamfests.
CAT DATA PROTOCOL
Serial data is passed via the CAT jack on the rear panel of the transceiver at 4800 bits/sec. All commands sent from the computer to the transceiver consist of five-byte blocks, with up to 200 ms between each byte. The last byte sent in each block is the instruction opcode, while the first four bytes of each block are ar­guments: either parameters for that instruction, or dummy values (required to pad the block out to five bytes):
CAT 5-BYTE COMMAND STRUCTURE
Byte 1
Argument
Each byte sent consists of one start bit, 8 data bits, no parity bit and two stop bits:
Start
Bit
There are twenty-nine instruction opcodes for the MARK-V FT-1000MP, listed in the table on pages 94 ~
97. Most of these duplicate menu programming set­tings or options, or else emulate front panel button func­tions. Notice that several instructions require no spe­cific parameters. However, every Command Block sent to the transceiver must always consist of five bytes.
The CAT control program you are writing must con­struct the 5-byte block, by selecting the appropriate instruction opcode, organizing the parameters, if any, and providing unused (dummy) argument bytes for padding the block to its required 5-byte length (the dummy bytes can contain any value). The resulting five bytes are then sent, opcode last, from the computer to the MARK-V FT-1000MP CPU via the serial port and CAT jack on the transceiver rear panel.

CONSTRUCTING AND SENDING CAT COMMANDS
Example #1: Set Main VFO-A to 14.25000 MHz;
Example #2: Activate a RX Clarifier Offset of +3.5 kHz.
r First determine the opcode for the desired instruc-
tion by referring to the CAT Commands Table. A good idea would be to store these opcodes within the program, so they can be looked up when the user requests the corresponding command.
r Here the instruction is “Set Main VFO Frequency,”
so the opcode (last byte of the block) is 0AH. Note - “H” s following each byte value indicate hexa­decimal (base 16) values.
r Build the four argument byte values from the de-
sired frequency by breaking it into 2-digit blocks (BCD “packed decimal” format). Note that a lead­ing zero is always required in the hundreds-of-MHz place (and another in the tens-of-MHz if below 10 MHz).

opcode 09H. Remember that the 1st and 2nd bytes are in BCD format.
r Completing the command byte sequence, we would
send, in sequence, 50H, 03H, 00H, 81H, 09H, to effect the Tx Clarifier offset.

DOWNLOADING
MARK-V FT-1000MP DATA
On command, the MARK-V FT-1000MP will down­load some or all (1,863 bytes) of its operational data. This data block contains all current transceiver settings. In addition, the current meter indication (Tx or Rx) is read, digitized and returned as well. This provides a wealth of information in near real-time that can be pro­cessed by your program or the running application for control purposes or display readouts. By regular or in­termittent requests for this data, the program (and you) can be kept continuously up-to-date on the status of the MARK-V FT-1000MP operating environment.
The following four commands cause the MARK-V FT-1000MP to download various operational and in­ternally stored settings via the CAT port:
Status Update (10H) - causes the transceiver to return all or portions of its RAM table (up to 1,863 bytes).
Status Flags Request (FAH) - obtains only the first 6 bytes (the Status Flags), plus 2 extra “Model ID” bytes (10H and 00H).
Read Meter (F7H) - returns the meter deflection (0
- FFH) repeated in four bytes, followed by one “filler” byte (F7H).
Pacing Command (0EH) - Each byte of returned data may be delayed by an interval determined by this command (0 to 255 ms in 1-ms steps). This delay is initially zero until the Pacing command is sent (see note below).
Note: Pacing allows returned data to be read and processed by slower computers. However, set it as short as your computer will allow, to minimize the inconvenience of the delay. Sending all 1,863 bytes requires just under 5 seconds with zero­length delay selected, but over 5 minutes if the maximum delay is selected!

STATUS UPDATE DATA ORGANIZATION
An overview of the Status Update Data that can be returned to the PC in response to one of the Status Update requests (opcodes 10H, FAH, F7H, or 0EH) is shown next page. The 1,863-byte block begins with six bytes, each containing one-bit state Status Flags (A), for a total of 48 bits, followed by one byte indicat­ing the current (or last selected) Memory Channel (B), followed by 116 x 16-byte data records: one for the current Operating Data (C), one each for VFO-A (D) and VFO-B (E), and one for each of the 113 memories (F).
Of the four commands that cause Status Update to be returned, remember that only opcode 10H (with its last argument set to zero) returns all of the data (see bottom left of this page).
STATUS FLAGS (BYTES 1~ 6)
Each of the first six bytes are subdivided into 1-bit flag fields: if a bit is set (1), the function is enabled (on); and if reset (0), the function is disabled (off). These flags reflect the current states of various transceiver functions, most of which appear in the radio display as indicators or LEDs. The Status Flags command returns these bytes for use in the control program (you could replicate these indicators on the computer display, or else use them as control flags for routines, etc.). Bit offsets for all six bytes is shown on page 89.
MEMORY CHANNEL DATA (BYTE 7)
The seventh Update Data Byte contains a binary value from 00 ~ 70H, corresponding to the current memory channel number on the display. Only this byte is returned by sending the Status Update command with the first parameter set to 1. The chart on page 90 lists the corresponding hexadecimal codes for memory channels 01 ~ 99, P1 ~ P9, and QMB memories 1 ~ 5.
16-BYTE DATA RECORDS (BYTES 8 ~ 1863)
The remainder of the operational data returned by the Status Update command consist of 16-byte data records, indicating VFO and memory-specific selec­tions. The first of these records is for the current dis­play, followed by the VFO-A, VFO-B, and then the 113 memory channels, from lowest to highest. Please re­view the table at the top left column on page 91, which outlines the structure of a 16-byte data record. Each byte is identified by its offset from the start (base ad­dress) of the record. A further breakdown of each byte offset is also provided.
Note that this same 16-byte data record format is used for the VFO and Memory Data as well, unless you are currently operating on a retuned memory (“M TUNE” displayed).

SELECTING UPDATE DATA TO
DOWNLOAD
As mentioned before, there are four opcodes that cause the MARK-V FT-1000MP to report (update) its operating status by downloading all or a portion of its 1,863 data bytes. These opcodes are shaded in the CAT Commands table (pages 94 ~ 97).
Status Update (Opcode 10H) - The 1st and 4th parameters of this command allow selecting different portions of Status data to be returned, as follows (“X” is the 1st parameter, “U” is the 4th):
Read Flags (Opcode FAH) -This command can be set to retrieve all six Status Flag bytes, or else five bytes
- three Status Flag Bytes, plus two transceiver ID bytes. The Status Flag Bytes are described on the preceding page, and in the Record Tables on the previous page.
The transceiver ID bytes are used in programs to distinguish the MARK-V FT-1000MP from other mod­els, which have different, unique values returned in this situation. The constant values of 03H and 93H are re­turned by the MARK-V FT-1000MP (and only the MARK-V FT-1000MP), as shown:
Flag Byte Flag Byte Flag Byte ID Byte 1 ID Byte 2

Read Meter Data (Opcode F7H) - Sending this com- mand returns a digitized meter deflection indication, between 00 and FFH (usually around F0H maximum). Four copies of this value are returned, along with one padding byte (F7H), as follows:

During reception, the signal strength deflection is returned. During transmission, the parameter repre­sented by the reading returned depends on the setting of the METER switch.

Important Note!
The Hex Memory Channel Codes for returned memory data shown above (Byte 7) are different than those used in upload command data (opcodes)!
The memory channel hex codes used as argument (parameter) bytes for opcodes are offset by one (that is, one value greater) from their returned data counterparts. Therefore the channel hex codes used in opcodes 02H, 03H, and 0DH would range from 01H ~ 71H.
When constructing command block bytes, ensure that the correct memory channel hex code is used!

The Band Selection data byte is divided into two 4­bit fields, representing the first and second value of the band number hex code. The Bit 0 and Bit 1 of the first field are used as flags for the memory mask and scan skip feature. A bit value of “1” means enabled, and “0” for disabled. Each value of the hex code is entered into its respective field in 4-bit binary format. The table below outlines the Data Byte field, and show an example of how the 24.5 ~ 25.0 MHz band would be read as:

Clarifier Offset - Clarifier offset is written using 16­bit binary data in two bytes. Negative offsets are ex­pressed in binary 2s-complement format, with a lead­ing bit flag value* of “1.” Although frequency resolution below 10 Hz cannot be viewed, absolute Clarifier off­sets down to 0.625 Hz can be read from downloaded data.
Arithmetic conversion must be done on the binary value to arrive at the actual frequency offset (multiply­ing the 16-bit binary offset by 0.625). For example, a binary value of 0011 1110 0110 1111 (3E6FH or 15,983) multiplied by 0.625 results in an offset of +9989.375 Hz.

A value of 1100 0001 1001 0001 (the 2-s comple­ment of the previous example) produces a minus off­set of -9989.375 Hz. See the byte chart below for a breakdown of the conversion process.

CODING EXAMPLES
Although Yaesu Musen does not provide CAT con­trol software (owing to the large variety of computers and operating systems used by our customers), the following are a few examples of critical CAT I/O func­tions, in Basic. Note that all variations of Basic may not support some of the commands, in which case alter­nate algorithms may need to be developed to dupli­cate the functions of those shown.
SENDING A COMMAND
After “opening” the computer’s serial port for 4800­baud, 8 data bits and 2 stop bits with no parity, as I/O device #2, any CAT command may be sent. How­ever, if you determine that your computer may need extra time to process data returned from the transceiver, you should send the Pacing command first. Here is an example of the Pacing command setting a 2-ms de­lay:
PRINT #2, CHR$(0);CHR$(0);CHR$(0);CHR$(2);CHR$(&HE);
Notice that the instruction opcode is sent last, with the first (MSB) parameter sent just before it, and the LSB parameter (or dummies) sent first. This means that the parameters are sent in the reverse order from that in which they appear in the CAT Commands table. Also note that in this and the following examples, we are sending zeros as dummy bytes; this is not neces­sary, however. If you decide to send commands through a 5-byte array, the values of the dummy parameters need not be cleared. Also note the semicolon at the end of the line, to prevent Basic from sending extra bytes to “end the line” (the CAT system control sys­tem is based on binary streams, not text streams).
Using the same example as on page 87, the follow­ing command could be used to set the frequency of the display to 14.25000 MHz:
PRINT #2, CHR$(&H00);CHR$(&H50);CHR$(&H42);CHR$(&H01); CHR$(&HA);
Notice here that the BCD values can be sent just by preceding the decimal digits with “&H” in this ex-
ample. However, in an actual program, it may be pref­erable to convert the decimal frequency variable in the program to an ASCII string, and then to convert the string to characters through a lookup table.
If you send a parameter that is out of range for the intended function, or not among the specified legal values for that function, the MARK-V FT-1000MP should do nothing. Therefore, you may wish to alter­nate your sending regular commands or command groups with the Read Flags or short-form Update com­mands, allowing the transceiver to let the computer know if everything sent so far has been accepted and acted upon as expected.
Bear in mind that some commands specify “binary,” as opposed to BCD formatted parameters. You can send binary parameters without going through the char­acter/hex string conversion process. For example, the CH parameter in the Command table is a binary value. You could have the MARK-V FT-1000MP recall memory channel 50 (decimal) by the following:
PRINT#2, CHR$(0);CHR$(0);CHR$(0);CHR$(49);CHR$(2);
Note that we must send 49 to get channel 50, since the channel numbers in the command start from 0, while those on the display start with 1.
READING RETURNED DATA
The reading process is easily done through a loop, storing incoming data into an array, which can then be processed after the entire array has been read. To read the meter:
FOR I=1 TO 5 MDATA(I) = ASC(INPUT$(1,#2)) NEXT I
Recall from above that the meter data consists of four identical bytes, followed by a filler byte, so we re­ally only need to see one byte to get all of the informa­tion this command offers. Nevertheless, we must read all five bytes (or 1, 16, or 1,863, in the case of the Up­date data). After reading all of the data, we can select the bytes of interest to us from the array (MDATA, in the above example).

Menu Selection and Settings
INTRODUCTION
In earlier chapters, basic and advanced operation were covered to explain the various transceiver fea­tures. This chapter covers all of the menu selections entries and their settings used by the transceiver. These functions were described previously, but must be con­figured as desired using menu programming. Menu selections are shown as they appear in the display to assist you as you go along.
MENU SELECTIONS
Eighty-two transceiver settings are contained in pro­gramming menu (refer to the menu list shown on the opposite page).
r To enter the “Menu” mode, press
then press [ENT]. r The SUB VFO-B display will show the selection
name, while the Main VFO display field shows the
current setting for the selected menu item. r Rotating the VRF/MEM CH knob displays the vari-
ous menu selections, whose numbers appear in the
memory channel box. r Rotating the Main VFO knob, once you have se-
lected a menu item, lets you choose between the
various settings available for the displayed selec-
tion. Some settings are merely an off/on switch,
while others are variable tuning step sizes, time and
frequency values, or mode choices.
Easy Recall Menu
Several menu selections can be accessed directly via two keystokes from the front panle:
