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 (Variable 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 6- dB 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-se- lected, cascaded 2ndand 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. Please feel free to contact your nearest dealer, or one of Yaesu’s national headquarters offices, for technical advice, interfacing assistance, or accessory recommendation. And watch Yaesu U.S.A.’s Home Page for late-breaking information about Yaesu products: http:/ /www.yaesu.com.

MARK-V FT-1000MP Operating Manual

Before initiating the installation of your MARK-V FT1000MP 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 FT1000MP 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.

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:

rIt can minimize the possibility of electrical shock to the operator.

rIt 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 laboratory test equipment.

rIt can minimize the possibility of erratic transceiver/ accessory operation caused by RF feedback and/ or improper current flow through logic devices.

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

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.

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.

SAFETY PRECAUTIONS

ELECTRICAL SHOCK PREVENTION

Be certain that all station wiring is properly insulated 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 FT1000MP transceiver and its accessories.

ANTENNA PRECAUTIONS

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, disconnect 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. Com- puter-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-to- Transceiver 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.

MARK-V FT-1000MP Operating Manual

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 FP29 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.

GENERAL SETUP

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 Ω resistive impedance at the desired operating frequency. While minor excursions from the 50 Ω 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:

rThe transceiver’s power amplifier protection circuitry will reduce power if the Automatic Antenna Tuner is unsuccessful in reducing the SWR.

rEven 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.

rAlthough 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 interference 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 Ω value.

Any antenna to be used with the MARK-V FT1000MP 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 (re- ceive-only) antennas connected to the RX ANT jack; if your receive-only antennas do not have an impedance near 50 Ω at the operating frequency, you may need to install an external antenna tuner to obtain optimum performance.

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.

(To Extend)

(To Retract)

Use high-quality 50 Ω 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 typi- cally-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.

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.

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.

MARK-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 FT1000MP.

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 FT1000MP 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.

rALC circuits which detect Power Output from the amplifier, and generate negative-going ALC control voltage when maximum output power has been realized, 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 potentiometer on the rear panel of the amplifier.

rALC circuits which detect Amplifier Tube Grid Current, and generate ALC voltage when excessive grid current is present, may not work well with the MARK-V FT-1000MP and other similar transceivers, as the ALC voltage may be generated because of amplifier mis-tuning not related to an excessivedrive 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.

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 MODES WITH A TNC

OR COMPUTER SOUND CARD (PSK-31)

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.

DIGITAL MODEM (TNC, WEATHERFAX, ETC.) INTERFACING

Construct a patch cable or cables to make the necessary 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 kΩ. 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 Ω) audio output line which is not affected by the position of the front-panel AF GAIN control.

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).

For FSK operation using the RTTY jack, the following 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,usemenu selection 8-6 to configure the "User" mode (see page 110) for PSK31 operation.

For most operation, you will want to use the PS31- U (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.

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-to- transceiver 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.

INTERFACING

AF OUT JACK

This is a 3.5 mm miniature stereo phone jack which provides constant-level (100 mV @ 600 Ω) 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 disconnect 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 keying cables, the key plugs may be inserted into the front and rear panel KEY jacks; now turn the front panel’s [KEYER] switch off.

ACCESSORY INSTALLATION

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.

ACCESSORY INSTALLATION

PERSONAL COMPUTER INTERFACING FOR CONTEST SOFTWARE, ETC.

The MARK-V FT-1000MP features a built-in level converter, allowing direct connection from the rearpanel CAT jack to the serial port of your computer, without the need for any external converter box.

When your software requests serial port configuration information, set it for “4800,N,8,2” (4800 baud, No Parity, 8 Data Bits, and 2 Stop Bits). Be certain to configure and activate any required “TSR” (Terminate-and- Stay-Resident) utilities before beginning computer-con- trolled transceiver operation (your software’s instruction manual will describe any such requirement).

Details regarding the programming protocols for the CAT system may be found beginning on page 86.

This chapter describes each control and connector on the MARK-V FT-1000MP. 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.

MARK-V FT-1000MP Operating Manual

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 transmitter switching in the SSB, AM and FM modes, and “semi- break-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.

page 22

MARK-V FT-1000MP Operating Manual

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.

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.

FRONT PANEL CONTROLS

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 voltage 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.

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.

19. EDSP Filters

(A) APF

Selects and indicates the bandwidth for the EDSP CW audio peaking filter. Pressing the [APF] switch selects the bandwidth to be used for the EDSP CW audio peaking filter, with available selections of 240(Hz)/ 120(Hz)/60(Hz)/DATA (DATA is an optimized bandwidth for FAX, PACKET or SSTV operation, user-optimized via the Menu), or “OFF,” and the indicator changes according to the bandwidth selected. The most narrow setting is highly useful for very-weak-signal CW work.

(B) NR

Selects and indicates the setting of the EDSP Noise Reduction feature. Pressing the [NR] switch selects one of four EDSP noise reduction settings, and the indicator changes according to the selection chosen (choose the selection providing the most effective reduction of noise under current operating conditions).

(C) CONTOUR

Press one of these four switches to select the desired EDSP (CONTOUR) filter.

: Low Cut Filter (High-frequency emphasis) Pressing this button activates the EDSP Low Cut Filter; the CONTOUR LED will glow green.

:Mid Cut Filter (High- & Low-frequency emphasis) Pressing this button activates the EDSP Medium Cut Filter; the CONTOUR LED will glow orange.

: High Cut Filter (Low-frequencies emphasis) Pressing this button activates the EDSP High Cut Filter; the CONTOUR LED will glow red.

OFF:

EDSP filter is off; the CONTOUR LED will go out.

20. MODE Selection Buttons

These momentary buttons select the operating mode, indicated by the LED in each button. Pressing AM, CW, RTTY, or PKT multiple times will switch between the alternate operating features that can be used by these modes (covered later). Also, when you press and hold in the [PKT] key for one second, the userprogrammed custom function setting mode will be activated.

21. CLASS-A Button

This button changes the final amplifier operating mode to Class-A. When operating the final amplifier in the Class-A mode, the maximum output power will be reduced to approximately 75 watts, and the LED inside this button will glow red. Operating SSB in Class- A yields an ultra-clean signal waveform.

22. FAST Button

For fast tuning, press this button (the “FAST” icon will appear), then rotate the main or sub tuning knobs (or press the UP(p) or DOWN(q) button). The tuning rate will increase ten times.

page 24

MARK-V FT-1000MP Operating Manual

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.

27. DOWN(q) & UP(p) Buttons

Pressing either of these buttons momentarily steps the operating frequency down or up 100 kHz, respectively. Pressing and holding the [FAST] button while pressing one of these buttons steps the frequency down or up 1 MHz. Continue holding either button for repeated stepping.

FRONT PANEL CONTROLS

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 receiving 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. [M uA] 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.

31. QMB Buttons

[RCL] (Recall) - Recalls one of up to five Quick Memory Bank memories for operation.

[STO] (Store) - Pressing this copies operating parameters into consecutive QMB Memories.

32. [DUAL] Button

This button activates dual-channel reception with the main and sub receivers. When this function is active, “DUAL” will be displayed in a box at the left edge of the display.

33. VFO & Memory Control

[AuB] Button:

Pressing this button for ½ second (until the double beep) transfers data from the main display (either Main VFO-A or a recalled memory channel) to Sub VFO-B, overwriting any previous contents in the Sub VFO. Use this key to set both Main and Sub Receivers to the same frequency and mode.

[AutB] Button:

Pressing this button momentarily exchanges the contents of Main VFO-A (or a recalled memory channel), and Sub VFO-B. No data is lost.

[M GRP] Button:

When more than one memory group has been enabled, pressing this button limits selection and scanning to those memories within the selected group.

[M CK] (Memory Check) Button:

This key displays the contents of memory channels without disturbing operation. When pressed, “M CK” is displayed above the channel number, and each memory channel can then be checked on the Sub Receiver display by rotating the VRF/MEM CH selector. Empty memory channels display as two decimals, with no frequency digits. Press this button again to cancel memory checking.

[AuM] Button:

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 “Operation” chapter for details.

page 26

MARK-V FT-1000MP Operating Manual

If the [ENT] key is pressed first, the yellow labels on the keys become effective, for manually entering any frequency one digit at a time; press [SUB(CE)] then [ENT] to enter Sub-VFO frequencies directly.

35. SUB VFO-B [RX & TX Switch-LED]

These lamps select and indicate the current status of Sub VFO-B. When the green “RX” lamp is lit, the receiving frequency is under control of SUB VFO-B. When the red “TX” lamp is lit, the transmitting frequency is under control of SUB VFO-B. During dual receive operation, the green “RX” lamps above both tuning knobs Main and Sub) will be illuminated.

36. SUB VFO-B Tuning Knob

This knob adjusts the Sub VFO-B operating frequency. The available tuning increments are the same as described for the main tuning knob, although each tuning knob’s increments may be set independently (see page 38).

37. [LOCK] Button

This button toggles locking of SUB VFO-B tuning to prevent accidental frequency changes. The red indicator in the display glows when this command is active (the tuning knob can still be turned, but it does nothing). Press the [LOCK] button again to re-enable the tuning knob.

38. SUB SQL Knob

This separate control sets the signal level threshold at which SUB VFO-B receiver audio is muted (and the green “SUB BUSY” display indicator turns off), in all modes. This control is normally kept fully CCW, except when scanning and during FM operation.

39. CW and Electronic Keyer Controls

[SPOT] button turns the CW receiver spotting heterodyne oscillator on and off.

[BK-IN] button turns full break-in (QSK) CW operation on and off.

[KEYER] button toggles the internal CW keyer on/ off, as indicated by the LED above this button.

[SPEED] knob adjusts the keying speed of the keyer.

40. PITCH Knob

Rotate this control to select your desired CW tone pitch (from 300~1050 Hz, in 50 Hz increments), as shown in the display. The Tx sidetone, receiver IF passband, and display offset from the BFO (carrier) frequency are all affected simultaneously.

FRONT PANEL CONTROLS

41. [CLAR] Buttons

Pressing the [RX] button activates the CLAR knob, to allow offsetting the receiving frequency temporarily (see item 42 below). The [TX] button provides the same function for the transmit frequency. If both buttons are pressed, the receiver and transmitter are both offset from the original frequency. Pressing the [CLEAR] button zeroes any offset tuned by the CLAR knob. Each memory and VFO retains all Clarifier settings independently.

42. CLAR Knob

This knob tunes the Clarifier offset frequency up to 9.99 kHz when activated by the CLAR [RX] [TX] buttons just below it (a 3-digit display appears in the center of the display (if enabled) when the Clarifier is active).

43. NOTCH Knob

This knob adjusts the IF notch frequency when this feature is activated by the [NOTCH] button located above this knob. When activated, the LED inside the [NOTCH] button glows red.

44. IDBT Indicator

This red indicator lights up when the IDBT System is activated by pressing the [IDBT] button on the Shuttle Jog. When this indicator is illuminated, the EDSP (Contour) filter’s bandwidth and center frequency changes according to the SHIFT and WIDTH knob settings.

45. SHIFT Knob

This knob offsets the center frequency of the IF passband when rotated from its “normal” (center) position. This control functions in all modes except FM.

When the IDBT System is activated by pressing the [IDBT] button on the Shuttle Jog, the EDSP (Contour) filter’s passband offset changes according to this knob’s setting.

46. WIDTH Knob

This knob, when turned from center, reduces the overall IF bandwidth from either the lower or upper side, from the maximum selected by the [BANDWIDTH] buttons.
