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 your transceiver will provide many hours of operating pleasure for years to come.

The FT-950 is an elite-class HF transceiver providing ex- ceptional performance both on transmit and receive. The FT-950 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 ceiver, and carrying the proud tradition of the FT-1000 series, the FT-950 provides up to 100 Watts of power output on SSB, CW, and FM (25 Watts AM carrier). Digital Signal Processing (DSP) is utilized throughout the design, providing leading-edge performance, both transmit and receive.

The Data Management Unit (DMU-2000) is available as an option for the FT-950. It provides extensive display capabilities via a user-supplied computer monitor. Included are Band Scope, Audio Scope, X-Y Oscilloscope, World Clock, Rotator Control, extensive Transceiver Status Displays, and Station Logging Capability.

For exceptional protection from strong signal interference, the optional RF μTuning Kits may be connected via the rear panel. The μTuning Kits provide extraordinarily sharp selectivity, and protect your receiver from close-in interference on a crowded band.

In the front end, you may select one of two RF preamplifiers, or IPO (Intercept Point Optimization) providing direct feed to the first mixer. Three levels of RF attenuation are available in 6-dB steps.

The FT-950 receiver utilizes DSP filtering, incorporating many of the features of the FTDX9000, such as, Variable Bandwidth, IF Shift, and Passband Contour tuning. Also provided are Digital Noise Reduction, Digital Auto-Notch Filtering and a manually tuned IF Notch filter.

On the transmit side, the Yaesu-exclusive Three-Band Parametric Microphone Equalizer allows precise and flexible adjustment of the waveform created by your voice and microphone. The Amplitude, Center Frequency, and Bandwidth are adjusted separately for the low, mid-range, and high-frequency audio spectra. The transmitted bandwidth may also be adjusted.

DX9000 trans-

Advanced features include: Direct Keyboard Frequency Entry and Band Change, Speech Processor, IF Monitor for Voice modes, CW Pitch control, CW Spot switch, Full CW QSK, adjustable IF Noise Blanker, and all-mode Squelch. Two TX/RX antenna ports are provided on the rear panel. Two key jacks are provided (one on the front and one on the rear panel). The key jacks may be configured independently for paddle input, connection to a straight key, or computer-driven keying interface. The CW Message Memory is provided.

Frequency setup is straightforward on the FT-950. Enter frequency directly for both VFO-A and VFO-B. Separate keys are provided for band selection. Each band key provides three separate VFO settings for three different parts of each band. You can establish three independent VFO settings of frequency, mode, and filter for each band.

In addition, 99 memories are provided to store: Frequency, Mode, IF filter selection, Clarifier offset, and Scan-skip status. What’s more, five quick-recall (“QMB”) memories can instantly store operational settings at the push of a button.

The built-in antenna tuner includes 100 memories that automatically store antenna matching settings for rapid automatic recall later.

Interfacing for digital modes is extremely simple with the FT-950, thanks to the dedicated RTTY/PKT connection jack on the rear panel. Optimization of the filter passband, DSP settings, carrier insertion point, and display offset for digital modes, is possible via the Menu programming system.

Advanced technology is only part of the FT-950 story. Vertex Standard stands behind our products with a worldwide network of dealers and service centers. We greatly appreciate your investment in the FT-950, and we look forward to helping you get the most out of your new transceiver.

 Pull the front legs outward from the bottom panel.  Rotate the legs counter-clockwise to lock them in the

extended position. Be sure the legs have locked securely in place, because the transceiver is quite heavy and an unlocked leg could result in damage, should the transceiver move suddenly.

   

Retracting the Front Feet

 Rotate the legs clockwise, and push them inward while

rotating to the right.

 The front feet should now be locked in the retracted

position.

ADJUSTING THE MAIN TUNING DIAL TORQUE

The torque (drag) of the Main Tuning Dial knob may be adjusted according to your preferences. Simply hold down the rear skirt of the knob, and while holding it in place rotate the knob clockwise to reduce the drag or counterclockwise to increase the drag. Available adjustment range is 120°.

INSTALLATION AND INTERCONNECTIONS

ANTENNA CONSIDERATIONS

The FT-950 is designed for use with any antenna system providing a 50 Ohm resistive impedance at the desired operating frequency. While minor excursions from the 50-Ohm specification are of no consequence, if the Standing Wave Ratio (SWR) present at the Antenna jack is greater than 3:1, the transceiver’s Automatic Antenna Tuner may not be able to reduce the impedance mismatch to an acceptable value.

Every effort should be made to ensure that the impedance of the antenna system be as close as possible to the specified 50Ohm value. Note that the “G5RV” type antenna does not provide a 50-Ohm impedance on all HF Amateur bands. An external wide-range antenna coupler must be used with this antenna type.

Any antenna to be used with the FT-950 must be fed from the transceiver with 50 Ohm coaxial cable. Therefore, when using a “balanced” antenna such as a dipole, remember that a balun or other matching/balancing device must be used to ensure proper antenna performance.

The same precautions apply to any additional (receive-only) antennas connected to the antenna jacks; if your receive-only antennas do not have impedance near 50 Ohms at the operating frequency, you may need to install an external antenna tuner to obtain optimum performance.

ABOUT COAXIAL CABLE

Use high-quality 50-Ohm coaxial cable for the lead-in to your FT-950 transceiver. All efforts at providing an efficient antenna system will be wasted if poor quality, lossy coaxial cable is used. This transceiver utilizes standard “M” (“PL-259”) type connectors.

INSTALLATION AND INTERCONNECTIONS

GROUNDING

The FT-950 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:

 It can minimize the possibility of electrical shock to the operator.  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 laboratory test equipment.

 It can minimize the possibility of erratic transceiver/accessory operation caused by RF feedback and/or improper cur-

rent flow through logic devices.

An effective earth ground system may take several forms; for a more complete discussion, see an appropriate RF engineering text. The information below is intended only as a guideline.

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 base 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 transceivers, power supplies, and data communications devices (TNCs, etc.) should be made directly to the ground bus using a heavy, braided cable.

Do not “Daisy-Chain” ground connections from one electrical device to another, and thence to the ground bus. This method 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 to ensure continued 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.

INSTALLATION AND INTERCONNECTIONS

CONNECTION OF ANTENNA AND POWER CABLES

Please follow the outline in the illustration regarding the proper connection of antenna coaxial cables, as well as the DC power cable. The DC power connector for the FT-950 must only be connected to a DC source providing 13.8 Volts DC (±10 %), and capable of at least 22 Amperes of current. Always observe proper polarity when making DC connection:

The RED DC power lead connects to the Positive (+) DC terminal. The BLACK DC power lead connects to the Negative (–) DC terminal.

Use a short, thick, braided cable to connect your station equipment to the buried ground rod (or alternative earth ground system).

We recommend the use of the FP-1030A AC Power Supply. Other models of power supplies may be used with the FT-950, but the 13.8 VDC input voltage, 22-Ampere current capability, and DC cable polarity guidelines described above must be strictly followed.

Note that other manufacturers may use the same type of DC power connections as does your FT-950 transceiver, however, the wiring configuration may be different from that specified for your transceiver. Serious damage can be caused if improper DC connections are made; consult with a qualified service technician when in doubt.

Permanent damage can result when improper supply voltage, or reverse-polarity voltage, is applied to the FT-950. The Limited Warranty on this transceiver does not cover damage caused by application of AC voltage, reverse

polarity DC, or DC voltage outside the specified range of 13.8 V ±10 %. When replacing fuses, be certain to use a fuse of the proper rating. The FT-950 requires a 25 A blade fuse.

ADVICE:

 Do not position the FT-950 in a location with direct exposure to sunshine.  Do not position the FT-950 in a location exposed to dust and/or high humidity.  Ensure adequate ventilation around the FT-950, to prevent heat build-up and possible reduction of performance due to

high heat.

 Do not install the FT-950 on an unstable desk or table. Do not place in a location where objects may fall onto it from above.  To minimize the possibility of interference to home entertainment devices, take all precautionary steps including sepa-

ration of TV/FM antennas from Amateur transmitting antennas to the greatest extent possible, and keep transmitting coaxial cables separated from cables connected to home entertainment devices.

 Ensure that the DC power cord is not subject to undue stress or bending, which could damage the cable or cause it to be

accidentally unplugged from the rear panel DC IN jack.

 Be certain to install your transmitting antenna(s) so they cannot possibly come in contact with TV/FM radio or other

antennas, or with power or telephone lines.

KEY, KEYER, AND COMPUTER-DRIVEN KEYING INTERCONNECTIONS

The FT-950 includes many features for the CW operator. These functions will be detailed in the “Operation” section later. Besides the built-in Electronic Keyer, two key jacks are provided, one on the front and one on the rear panel, for convenient connection to keying devices.

The Menu selections allow you to configure the front and rear panel KEY jacks according to the device you wish to connect. For example, you may connect your keyer paddle to the front panel KEY jack, and use Menu item “

TYPETYPE

TYPE” for paddle input, and also connect the keying line from your personal computer (which emulates a “straight key”),

TYPETYPE

to the rear panel KEY jack, and configure the rear panel jack using Menu item “

Both KEY jacks on the FT-950 utilize “Positive” keying voltage. Key-up voltage is approximately +3.3V DC, and keydown current is approximately 0.3 mA. When connecting a key or other device to the KEY jacks, use only a 3-contact (“stereo”) 1/4” phone plug; a 2-contact plug will place a short between the ring and (grounded) shaft of the plug, resulting in a constant “key-down” condition in some circumstances.

NOTE

 The TX GND OUT pin (pin 2) of the LINEAR jack is

a transistor “open collector” circuit. It is capable of handling positive relay coil voltages up to +60VDC at 200 mA or +30 VDC at 1 A. If you plan to use multiple linear amplifiers for different bands, you must provide external band switching of the “Linear Tx” relay control line from the “TX GND OUT” line at the LIN- EAR jack.

 The specified range for ALC voltage to be used with

the FT-950 is 0 to -4 Volts DC.

 Amplifier systems utilizing different ALC voltages will

not work correctly with the FT-950, and their ALC lines must not be connected if this is the case.

Note

When the FC-40 is connected to the FT-950, TX GND (pin 2) of the TUNER jack and the LINEAR jack (pin 2) are common circuits.

Therefore, the maximum voltage at TX GND (pin

2) of the LINEAR jack must not exceed +5V.

IMPORTANT NOTE!

 Do not exceed the maximum voltage or current ratings

for the “TX GND OUT” pin (pin 2) of the LINEAR jack. This line is not compatible with negative DC voltages, or AC voltages of any magnitude.

 Most amplifier control relay systems require only low

DC voltage/current switching capability (typically, +12V DC at 25 ~ 75 mA), and the switching transistor in the FT-950 will easily accommodate such amplifiers.

ADVICE:

 The Speech Processor is a tool for increasing the

average power output through a compression technique. However, if the Processor level is advanced too far, the increase in compression becomes counter-productive, as intelligibility will suffer. We recommend that you monitor the sound of your signal using the Monitor (with headphones).

1. Turn on the external DC power supply.

2. Press and hold in the front-panel [POWER] switch until the transceiver turns on. After about five seconds (ten seconds if the optional μ-Tuning Kit is connected), the transceiver is ready for full operation.

3. The transceiver will start up on 7.000.00 MHz LSB, and normal operation may begin.

NOTE:

To turn power off, press and hold in the front panel [

POWER] switch for two seconds.

4. Rotate the [AF GAIN] knob to set a comfortable audio level on incoming signals or noise. Clockwise rotation of the [AF

GAIN] knob increases the vol-

ume level.

NOTE:

When using headphones, start by rotating the [AF

GAIN] knob counter-clockwise, then bring the volume

level up after you put the headphones on. This will minimize the chance of damage to your hearing caused by an unexpectedly high audio level.

5. Press the [(VFO-A)RX

]

Indicator/Switch to engage the VFO-A; the imbedded LED will glow green.

ADVICE:

If you press the [(VFO-

A)RX] Indicator/Switch

when the imbedded LED is already glowing green, the LED will now blink “on” and “off”; this indicates that the VFO-A receiver is temporarily muted. Just press the [(VFO-A)RX] Indicator/Switch once more to restore VFO-A receiver operation.

6. Press the [BAND] button corresponding to the Amateur band on which you wish to begin operation.

ADVICE:

 One-touch selection of each Amateur band between

1.8 and 50 MHz is provided.

 The FT-950 utilizes a triple band-stack VFO se-

lection technique, which permits you to store up to three favorite frequencies and modes onto each band’s VFO register. For example, you may store one frequency each on 14 MHz CW, RTTY, and USB, then recall these frequencies by successive, momentary presses of the [14] MHz band button. Each Amateur band button may similarly have up to three frequency/mode settings applied.

 When the [BAND] button is pressed, the imbed-

ded LED will glow orange, and the [CLAR/VFO-

B] knob may be used as a band selection knob.

 When the [MHz] button (located to the left of the

[

CLAR/VFO-B] knob), is pressed, the imbedded

LED will glow orange, and then rotation of the [

CLAR/VFO-B] knob will change the frequency

in 1 MHz steps.

7. Press the [ANT 1-2] button to select the appropriate antenna for the band in use. Two TX/RX antennas may be used or one for TX and one RX-only antenna.

ADVICE:

When you make an antenna selection, that antenna is “remembered” by the microprocessor in conjunction with the VFO register in use.

Page 30 FT-950 OPERATING MANUAL

Page 33

BASIC OPERATION:RECEIVING ON AMATEUR BANDS

8. Press the appropriate [MODE] button to select the desired operating mode. Pressing the [SSB] button toggles the LSB and USB mode, and also pressing the

[

AM/FM] button toggles the AM and FM

mode.

ADVICE:

 By convention in the Amateur bands, LSB is used

on the 7 MHz and lower bands (with the exception of 60 meters), while USB is utilized on the 14 MHz and higher bands.

 When changing modes from SSB to CW, you will

observe a frequency shift on the display. This shift represents the BFO offset between the “zero beat” frequency and the audible CW pitch (tone) you can hear (the pitch is programmed via the Menu item

045 A1A PITCH045 A1A PITCH

“

045 A1A PITCH”), even though the actual tone

045 A1A PITCH045 A1A PITCH

that you hear is not changing. If you do not want this frequency shift to appear when changing modes from (for example) USB to CW, use the Menu item

047 A1A FRQDISP047 A1A FRQDISP

“

047 A1A FRQDISP”, described on page 112.

047 A1A FRQDISP047 A1A FRQDISP

 When operating on the FM mode, rotate the [SQL

(Squelch) knob clockwise to the point where the background noise is just silenced. This is the point of maximum sensitivity to weak signals. Excessive advancement of the [SQL] knob will degrade the ability of the receiver to detect weak signals.

9. Rotate the Main Tuning Dial knob to tune around the band, and begin normal operation.

ADVICE:

 Clockwise rotation of the Main Tuning Dial knob

increases the operating frequency, one “step” of the synthesizer at a time; similarly, counter-clockwise rotation of the Main Tuning Dial knob will decrease the frequency. Two settings, one “normal” and one “fast”, are available on each operating mode. Pressing the [FAST] button engages the “Fast” tuning

]

selection, see chart below.

 It is possible to set the frequency change over one

dial rotation, separately for the CW mode, using the Menu items “

BASIC OPERATION:RECEIVING ON AMATEUR BANDS

CLAR (CLARIFIER) OPERATION

The [TX CLAR], [RX CLAR], [CLEAR] buttons and [CLAR/VFO-B] knob are used to offset the receive frequency, the transmit frequency, or both, from their settings on the VFO-A frequency. Four small numbers on the Multi-Display Window show the current Clarifier offset. The Clarifier controls on the FT-950 are designed to allow you to preset an offset (up to ±9.990 kHz) without actually retuning, and then to activate it via the Clarifier’s [RX CLAR] and [TX CLAR] buttons. This feature is ideal for following a drifting station, or for setting small frequency offsets sometimes utilized in DX “Split” work.

[

Here is the technique for utilizing the Clarifier:

1. Press the [RX CLAR] button. In the Multi-Display

Window, the “RX” notation will appear, and the programmed offset will be applied to the receive frequency.

2. Rotation of the [CLAR/VFO-B] knob will allow you to modify your initial offset on the fly. Offsets of up to ±9.99 kHz may be set using the Clarifier.

To cancel Clarifier operation, press the [RX CLAR] button. The “RX” notation will disappear from the display.

ADVICE:

 Turning the Clarifier off simply cancels the applica-

tion of the programmed offset from the receive and/or the transmit frequencies. To clear the Clarifier offset, and reset it to “zero,” press the [CLEAR] button. The programmed offset is displayed in the small multi-channel window of the frequency display.

 You may also activate the clarifier on the VFO-B fre-

quency. In this case, the offset frequency is set using the Main Tuning Dial knob, instead of the [CLAR/

VFO-B] knob (VFO-B operation is discussed on page

35).

 The Clarifier operation (including the offset frequency)

will be memorized independently on each VFO stack of VFO-A and VFO-B.

USING THE VFO-B

VFO-B operates similar to VFO-A, which you should be familiar with by now. However, the [CLAR/VFO-B] knob, instead of the Main Tuning Dial knob selects the frequency for VFO-B (See box below for tuning rate). The two VFOs make simple transmit/receive split frequency operation possible. Use various combinations of the four VFO red and green transmit and receive switches to set up split frequency operation. The [SPLIT] button also sets up split frequency operation. See page 69 for details about SplitFrequency Operation

The frequency and mode data can be transferred from VFOA to VFO-B by pressing the [AXB] button, don’t forget that this will overwrite any settings that were in VFO-B previously. Also, the contents of the two VFOs can be swapped (with no loss of data) by pressing the [A button.

The FT-950 utilizes a triple band-stack VFO selection technique, that permits you to store up to three favorite frequencies and modes onto each band’s VFO register. For example, you may store one frequency each on 14 MHz CW, RTTY, and USB, then recall these VFOs by successive, momentary presses of the [14] MHz band button. Each Amateur band key may similarly have up to three frequency/mode settings applied. Both the VFO-A and VFO-B systems have their own, independent, band stacks.

A typical setup, for the 14 MHz band, might be arranged like this:

[

1. Program 14.025 MHz, CW Mode, then press the [14 MHz band button;

2. Program 14.080 MHz, RTTY Mode, then press the [14 MHz band button;

3. Program 14.195 MHz, SSB Mode, then press the [14 MHz band button.

With this configuration, successive momentary presses of the [14] MHz band button will allow you to step sequentially through these three VFOs.

INTERFERENCE REJECTION

RECEIVER OPERATION (FRONT END BLOCK DIAGRAM

The FT-950 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 a general guideline for typical situations, and a starting point for your own experimentation.

The FT-950’s interference-fighting circuitry begins in its “RF” stages, and continues throughout the entire receiver section.

FT-950 allows configuration of the features described below.

R. FLT (IF Roofing Filters

Three Roofing filters, of 15 kHz, 6 kHz, and 3 kHz bandwidths, are provided in the 69 MHz First IF, right after the first mixer. These filters are automatically selected to provide narrow-band selectivity to protect the following IF and DSP stages. The automatically selected filter, may be manually changed by the operator, if desired, for special operating circumstances.

CONTOUR Filter

The DSP Contour filter has the unique ability to provide either a null or a peak in tunable segments of the receiver passband. You may suppress interference and excessive frequency components on an incoming signal, or you may peak those tunable frequency segments. The level of the null or peak, and the bandwidth, over which it is applied, are adjustable via the Menu.

IF SHIFT

The passband center frequency of the IF DSP filter may be moved up or down by adjusting this control.

(

SEE PAGE 48

(

SEE PAGE 47

(SEE PAGE 45

IF NOTCH

The IF Notch filter is a high-Q notch filter that can significantly reduce, if not eliminate, an interfering carrier.

(

SEE PAGE 51

)

DNF (Digital Notch filter

When multiple interfering carriers are encountered during reception, the Digital Notch Filter can significantly reduce the level of these signals.

DNR (Digital Noise Reduction

The DSP’s Digital Noise Reduction (DNR) feature utilizes 15 different mathematical algorithms to analyze and suppress different noise profiles encountered on the HF/ 50 MHz bands. Choose the selection that provides the best noise suppression, and allows the signal to rise up out of the noise.

(

AGC

The AGC system is highly adaptable to changing signal and fading characteristics, making reception possible under the most difficult conditions.

ATT

When extremely strong local signals or high noise, still degrades reception, you can use the [ATT] button to insert 6, 12, or 18-dB of RF attenuation in front of the RF amplifier.

[

1. Press the [ATT] button several times to set the desired attenuation level, per the chart below.

: Attenuator is Off : The incoming signal power is reduced by 6

dB (Signal voltage reduced by 1/2)

: The incoming signal power is reduced by 12

dB (Signal voltage reduced to 1/4)

: The incoming signal power is reduced by 18

dB (Signal voltage reduced to 1/8th) The selected attenuation level will be indicated in the ATT column of the Block Diagram Display on the display.

2. To restore full signal strength through the Attenuator circuit area, press the [ATT] button to restore the ATT display to the “OFF” position.

Block Diagram Display

ATT] Button

BLOCK DIAGRAM DISPLAY

ADVICE:

 The attenuator selection will be memorized independently on each VFO stack of the VFO-A and VFO-B.  If background noise causes the S-meter to deflect on clear frequencies, press the [ATT] button until the S-meter drops

to about “S-1”. This setting optimizes the trade-offs between sensitivity, noise, and interference immunity. Also, once you have tuned in a station you want to work, you may want to reduce sensitivity further (add more attenuation) by pressing the [ATT] button to a higher 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] button should be set to “OFF.” 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.

μ-TUNE FILTER (REQUIRES THE OPTIONAL RF μTUNING KIT

The RF μTuning Kit provides ultra-sharp RF selectivity for the front end of the transceiver. Very high Q is made possible by the narrow-band design. Three RF μTuning Kits are available. The MTU-160 covers the 1.8 MHz band. The MTU-80/ 40 covers the 3.5 and 7 MHz bands. The MTU-30/20 covers 10.1 and 14 MHz bands.

When any (or all) of the three optional units are connected, they will be automatically adjusted to center on your operating frequency.

The narrow bandwidth is especially useful on the low bands, when many strong signals are being received via NVIS propagation (Near Vertical-Incidence Signals) within a narrow bandwidth. The added protection for the RF stage is especially helpful in preventing IMD and blocking.

μ-Tune Operation

1. Press the [μ-TUNE] button to activate the μ-Tune filter. The LED inside the [μ-TUNE] button glows orange. The [SELECT] knob works as the μ-TUNING knob.

INTERFERENCE REJECTION

μ-TUNE FILTER (REQUIRES THE OPTIONAL RF μTUNING KIT

ADVICE:

 The μ-Tune filters are the most advanced, selective RF preselector filters ever incorporated into an Amateur Radio

transceiver. The RF selectivity provided by μ-Tune can be of tremendous value in ensuring quiet, intermod-free recep- tion even in the most crowded bands on a contest weekend. The μ-Tune filters provide RF selectivity on the order of a few dozen kHz at -6 dB, at the expense of a few dB of system gain on bands where noise figure is seldom an issue. You will notice that the S-meter deflection, when μ-Tune is engaged, is slightly less than when it is out of the circuit; this is normal. If your antenna system gain is so low that you cannot hear the band noise when μ-Tune is engaged (highly unlikely), just switch it out, to eliminate the slight insertion loss.

 As you tune around on an amateur band with μ-Tune engaged, the microprocessor automatically commands the stepper

motor driving the toroid core stack to center the filter on your current operating frequency. You may, however, use the [

SELECT(μ-TUNE)] knob to skew the filter response to one side or the other from your operating frequency, to deal

with heavy interference on one side. To re-center the μ-Tune filter on your operating frequency, and eliminate any offset, press the [CLEAR] button.

QUICK NOTE:

The permeability-tuning concept utilized in the μ-Tune circuit dates back many decades, as it was incorporated in such classic transceivers as the FT-101, the FT-901 series, the FTDX400, and similar models. The μ-Tuning Kit uses the same circuit as our flag ship model the FTDX9000, which is the highest development of this circuit concept ever employed in an Amateur transceiver.

ADVICE:

 The IPO selection will be memorized independently

on each VFO stack of VFO-A and VFO-B.

 On the 10 MHz and lower bands, it generally is not

necessary to use any preamplifier at all; selecting the “IPO ON” position as described above will increase the strong-signal-handling capability of the receiver, and generally will result in more pleasant reception due to reduced noise. If you can hear band noise with the preamplifiers disengaged, then a preamplifier is generally not needed.

 When the optional DMU-2000 Data Management Unit

is connected, the Audio Scope (on the “Oscilloscope” page) is particularly useful when adjusting the Contour control. Not only can you see the effect of the null/peak of the Contour system, but you also can see the position of the null/peak with respect to frequency components of interest on the incoming signal. You may then observe (on the Audio Scope) the effect of the Contour control while listening to the effect on the signal, and this will help build your intuition on how best to use Contour tuning in the future.

Refer to Figure “B”, this illustrates an “indentation” of the Contour filter in the center of the passband. The Contour filter is placing a low-Q “notch” (per the setting of Menu item “

clockwise rotation (to the left) of the [SELECT knob causes the notch to move towered a lower frequency within the passband, while clockwise rotation (to the right) causes the notch to move toward a higher frequency within the passband. By removing interference or unwanted frequency components of the incoming signal, it is possible to make the desired signal rise out of the background noise/interference, enhancing intelligibility.

AB C

BANDWID TH

BANDWIDT H

]

QUICK POINT:

The steep slopes of the DSP filtering, when adjusted aggressively, can impart an unnatural sound to an incoming signal. Often, a narrow bandwidth is not the key to improving copy; the incoming signal itself may have undesirable or excessive frequency components, especially in the low frequency range around 100-400 Hz. By judicious use of the Contour filter, the “shoulder” of the passband response may be altered, or components may be removed from within the passband, allowing the desired signal to rise above the background noise and interference in a manner not obtainable with other filtering systems.

Page 47FT-950 OPERATING MANUAL

Page 50

INTERFERENCE REJECTION

IF SHIFT OPERATION (SSB/CW/RTTY/PKT/AM MODES

)

IF SHIFT allows you to move the DSP filter passband higher or lower, without changing the pitch of the incoming signal, and thus reduce or eliminate interference. Because the carrier tuning frequency is not varied, there is no need to re-tune the operating frequency to eliminate the interference. The total passband tuning range for the IF SHIFT system is ±1 kHz.

RF GAIN (SSB/CW/AM MODES

The RF Gain control provides manual adjustment of the gain levels for the receiver RF and IF stages, to account for noise and signal strength conditions at the moment.

1. The [RF GAIN] knob should, initially, be rotated to the fully clockwise position. This is the point of maximum sensitivity.

2. Counter-clockwise rotation of the [RF GAIN] knob will gradually reduce the system gain.

ADVICE:

 As the [RF GAIN] knob is rotated counterclockwise

to reduce the gain, the S-meter reading will rise. This indicates that the AGC voltage being applied to the receiver is increasing (which causes a reduction in receiver gain).

 Rotating the [RF GAIN] knob control to the fully

counter-clockwise position will essentially disable the receiver, as the gain will be greatly reduced. In this case, the S-meter will appear to be “pegged” against the right edge of the analog S-meter scale.

QUICK POINT:

 Reception frequently can be optimized by rotating the

[

RF GAIN] knob slightly counter-clockwise to the

point where the “stationary” meter indication is set just about the same as the incoming noise level. This setting ensures that excessive gain is not being utilized, without so much gain reduction that incoming signals cannot be heard.

 The RF Gain control, along with the IPO and the At-

tenuator features, all affect the system receiver gain in different ways. The IPO generally should be the first feature engaged when dealing with a high noise level, or a crowded, high-level signal environment, the IPO generally should be the first feature engaged, if the frequency is low enough to allow the preamplifier to be bypassed. Thereafter, the RF Gain and Attenuator features may be employed to provide precise, delicate adjustment of the receiver gain to fully optimize performance.

AGC (AUTOMATIC GAIN CONTROL

The AGC system is designed to help compensate for fading and other propagation effects. The AGC characteristics can be individually set for each operating mode. The basic objective of AGC is to maintain a constant audio output level once a certain minimum threshold of signal strength is achieved.

Press the [AGC] button repeatedly to select the desired receiver-recovery time constant. You will observe the AGC status notation in the AGC column of the Block Diagram Display on the display, denoting the AGC receiver-recovery time currently in use. For most operations, we recommend the “AUTO” mode. Additionally, you may disable the AGC by pressing and holding in the [AGC] button for one second.

NOTE:

Pressing the [AGC] button allows selection of the desired receiver-recovery time constant. Normally, the “AUTO” selection is satisfactory for most situations, but in the event of operation on a crowded band where you wish to receive a weak signal, you may wish to change the setting to FAST. The AUTO mode selections are:

 If the AGC receiver-recovery time is set to “Off” by

pressing and holding in the [AGC] button, the S-meter will no longer deflect. Additionally, you will likely encounter distortion on stronger signals, as the IF amplifiers and the following stages are probably being overloaded.

QUICK POINT:

Several aspects of AGC performance may be configured via the Menu. However, because AGC can have such a profound impact on overall receiver performance, we generally do not recommend any changes to the AGC Menu selections until you are thoroughly familiar with the performance of the FT-950.

TERMINOLOGY:

Automatic Gain Control, or AGC, is a circuit that senses the incoming signal strength, and then limits the gain of the RF and IF stages to keep the output audio volume at a more-or-less constant level. AGC also protects the RF, IF, Audio, and DSP stages from overload, as it limits the signal strength that is allowed to flow, irrespective of the input signal level.

SSB/AM MODE TRANSMISSION

ADVICE:

 ALC meter deflection may be caused by excessive drive

power, but also by reflected power detected in the antenna system. If the impedance presented to the transceiver is different from 50 Ohms, ALC meter action may be observed that is not related to the proper setting of the [MIC GAIN] knob. Therefore, we recommend that you make the [MIC GAIN] knob adjustments into a dummy load or antenna system presenting impedance very close to 50 Ohms.

USING THE AUTOMATIC ANTENNA TUNER

The Automatic Antenna Tuner (hereinafter referred to as the “ATU”) built into each FT-950 is designed to ensure a 50Ohm load for the final amplifier stage of the transmitter. We recommend that the ATU be used whenever you operate on the

FT-950.

ADVICE:

 Because the ATU of the FT-950 is located inside the station, it only adjusts the impedance presented to the transceiver

at the station end of your coaxial cable feedline. It does not “tune” the SWR at the antenna feed point itself. When designing and building your antenna system, we recommend that every effort be made to ensure a low SWR at the antenna feed point.

 The ATU of the FT-950 includes 100 memories for tuning data. Eleven of these memories are allocated, one per

Amateur band, so that each band has at least one setting preset for use on that band. The remaining 89 memories are reserved for the 89 most-recent tuning points, for quick frequency change without the need to retune the ATU.

 The ATU in the FT-950 is designed to match impedances within the range of 16.5 Ohms to 150 Ohms, corresponding

to an SWR of 3:1 or less on the 160 through 6 meter amateur bands. Accordingly, simple non-resonant whip antennas, along with random-length wires and the “G5RV” antenna (on most bands) may not be within the impedance matching range of the ATU.

ATU OPERATION

[

1. Use the Main Tuning Dial knob to set the radio to the desired operating frequency within the Amateur band.

2. Press the [TUNE] button momentarily to place the ATU in the transmit line (no adjustment/tuning will occur yet). The “ ” icon will appear in the display.

QUICK POINT:

The momentary press of the [TUNE] button will turn the tuner on, and the microprocessor will automatically select the tuning point closest to the current operating frequency.

3. Press and hold in the [TUNE] button for one second to begin automatic tuning. The transmitter will be engaged, and the “ ” icon will blink while tuning is in progress. When the optimum tuning point has been reached, the radio will return to receive, and the “ ” icon will again glow steadily (instead of blinking).

4. To disconnect the ATU from the transmit line, press the [TUNE] button momentarily. The “ ” icon will turn off, confirming that the ATU has been turned off. In the “Off” mode, the transceiver will be directly connected to the coaxial cable connected to your antenna, and will operate based on whatever impedance is present at the station end of the coax.

ADVICE:

The ATU circuit is located between the final amplifier and the rear-panel antenna jack; reception is not affected by the ATU.

TUNE] Button

QUICK POINTS:

As shipped from the factory, only one ATU alignment point is saved on each Amateur band. This was memorized during the final alignment and performance verification stages on the production line.

NOTE:

Please check the operating frequency before beginning the tuning process, to be sure you are not interfering with others who may already be using the frequency.

TERMINOLOGY:

Antenna Tuner Memories: The microprocessor of the ATU makes a note of the positions of the tuning capacitors and the selected inductors, and stores the data for each 10 kHz window in which tuning has occurred. This eliminates the need to re-tune every time you return to a frequency on which you have already completed the tuning process.

ABOUT ATU OPERATION

Figure 1 depicts a situation where normal tuning via the ATU has been successfully completed, and the tuning data has been stored in the ATU memory. The antenna system as seen by the transmitter is shown.

In Figure 2, the operator has changed frequency, and the “ ” icon has appeared. The operator presses and holds in the [TUNE] button for two seconds to begin impedance matching using the ATU.

If a high SWR condition exists (above 3:1), corrective action must be taken in the antenna system to bring the impedance closer to 50 Ohms. The ATU will refuse to memorize settings on frequencies where the SWR exceeds 3:1. A High SWR may indicate a mechanical failure in the feed system, and can lead to the generation of spurious signals causing TVI, etc.

ENHANCING TRANSMIT SIGNAL QUALITY

PARAMETRIC MICROPHONE EQUALIZER (SSB/AM/FM MODE

The FT-950 includes a unique Three-Band Parametric Microphone Equalizer that provides precise, independent control over the low, mid and treble ranges in your voice waveform. You may utilize one group of settings when the speech processor is off and an alternate group of settings when the speech processor is on. The speech processor feature is described in the next chapter.

QUICK POINT:

The Parametric Equalizer is a unique technique for adjusting the signal quality. The three audio ranges may be adjusted so precisely, it is possible to craft an audio response that provides a natural and pleasant sound that you may not have ever experienced before. Alternately, the Effective “talk power” can be significantly enhanced.

The aspects of configuration that you may adjust on the Parametric Equalizer are:

Center Frequency: The center frequency of each of the three bands may be adjusted. Gain: The amount of enhancement (or suppression) within each band may be adjusted. Q: The bandwidth over which the equalization is applied may be adjusted.

)

Setup of the Parametric Microphone Equalizer

1. Connect the microphone to the MIC jack.

2. Set the RF output power to minimum value via the Menu item “ cause interference to other users while making adjustments.

ADVICE:

 We recommend that you connect a dummy load to

while listening to the effect of the changes you are making. Because the overall effect on the sound will change with each adjustment, you should make several passes through each adjustment area, to be sure that you are achieving the optimum settings.

9. When you have completed all adjustments, press and hold in the [MENU] button for one second to save the new settings and exit to normal operation. If you only press the [MENU] button momentarily to exit, none of the changes you performed will be stored.

ADVICE:

To roll off excessive bass response in a wide-range studio microphone, try putting a 10 dB null at 100 Hz with a bandwidth of “1” or “2”, do about a 3 dB null centered on 800 Hz with a bandwidth of “3,” and then put an 8 dB peak centered on 2100 Hz with a bandwidth of “1.” These are starting recommendations; each microphone and user’s voice will be different, often requiring different settings.

ENHANCING TRANSMIT SIGNAL QUALITY

ADJUSTING THE SSB TRANSMITTED BANDWIDTH (SSB MODE)

For transmission on SSB, a default bandwidth of 2.4 kHz is provided. This bandwidth provides reasonable fidelity along with good talk power, and is typical of the bandwidth used for decades for SSB transmission. The bandwidth may be varied by the operator, to provide different levels of fidelity or talk power, according to your preferences.

[

Here are the steps to adjust the SSB transmit bandwidth:

1. Press the [MENU] button momentarily to engage the Menu.

2. Rotate the [SELECT] knob to select Menu item “

pear in the display, indicating that the Monitor is turned on.

2. During transmission, rotate the [MONI] knob to ad-

just the audio level in the Headphones or speaker. Clockwise rotation of this knob will increase the volume level.

3. To switch the Monitor off again, press the [MONI

ADVICE:

 If you are using the speaker for monitoring, excessive

advancement of the [MONI] knob can cause feedback to occur. This feedback can cause the VOX system to hang up in a loop, making it impossible for VOX to return to receive. Therefore, we recommend the use of headphones, if possible. If the speaker must be used, adjust the [MONI] knob to the minimum useable setting.

 Because the Monitor feature samples the transmitter

IF signal, it can be very useful for checking the adjustment of the Speech Processor or Parametric Equalizer on SSB, and for checking the general signal quality on AM and FM.

QUICK POINT:

The Clarifier is frequently used for receiver offset tuning. However, for DX pile-ups where the DX station is using a split of less than 10 kHz, the TX Clarifier function is usually the quickest way to set the transmitter to the desired offset frequency.

2. Rotate the [CLAR/VFO-B] knob to set the desired transmitter offset. A maximum split of ±9.99 kHz may be set.

3. To exit from TX Clarifier operation, press the [TX

CLAR] button once more. The “TX” icon will disap-

pear from the Multi-Display Window.

ADVICE:

 When listening to a “pile-up” calling a DX station, in

order to find the station currently being worked, you may press the [RX CLAR] button. Then, use the

[

CLAR/VFO-B] knob to zero in on the station calling

the DX (use the SPOT function on CW for precise alignment of your frequency). You may then press the

[

RX CLAR] button again to cancel the RX Clarifier,

and return to reception on the DX station’s frequency.

 Just as with receiver Clarifier operation, the amount of

offset from the original VFO frequency will appear in the small display window.

 As with receiver Clarifier operation, when you turn the

TX Clarifier off the last-used offset is remembered, and will be available if you turn the TX Clarifier back on. To clear the Clarifier offset, press the [CLEAR] button.

 When you operate on the VFO-B frequency, you may

also activate the Clarifier on the VFO-B frequency. However, the offset frequency is set using the Main Tuning Dial knob, instead of the [CLAR/VFO-B knob.

 The Clarifier operation (including the offset frequency)

will be memorized independently on each VFO stack of the VFO-A and VFO-B.

QUICK POINT:

When attempting to work a DX station on CW in a split frequency pile-up, remember that a large number of other stations may also be using Yaesu transceivers with capability similar to that of your FT-950. On the DX side of the pile-up, everyone calling precisely on the same CW frequency will sound like a single tone! So you may have more success if you use the RX Clarifier to find a hole in the pile-up, instead of trying to zero-beat the last station worked by the DX station.

CW CONVENIENCE FEATURES

CW SPOTTING (ZERO-BEATING

“Spotting” (zeroing in on another CW station) is a handy technique to ensure you and the other station are precisely on the same frequency.

The Tuning Offset Indicator in the display may also be moved so you can adjust your receiver frequency to center the incoming station on the pitch corresponding to that of your transmitted signal.

)

Using the SPOT System

While pressing the front panel [SPOT] button, the Spot tone will be heard through your speaker and the frequency display will show the Spot tone frequency. This tone corresponds to the pitch of your transmitted signal. If you adjust the receiver frequency until the pitch of the received CW signal matches that of the Spot tone, your transmitted signal will be precisely matched to that of the other station.

Release the [SPOT] button to turn the Spot tone off.

ADVICE:

 In a tough DX pile-up, you may actually want to use

the SPOT system to find a “gap” in the spread of calling stations, instead of zeroing in precisely on the last station being worked by the DX station. From the DX side, if a dozen or more operators (also using Yaesu’s SPOT system) all call precisely on the same frequency, their dots and dashes merge into a single, long tone that the DX station cannot decipher. In such situations, calling slightly higher or lower in frequency may get your call through.

 The Tuning Offset Indicator in the display may be uti-

lized for CW frequency adjustment, as well. Its configuration is set via Menu item “ at the factory, and the Tuning Offset Indicator is already set to the “

C-tnC-tn

C-tn” selection.

SPOT] Button

QUICK POINTS:

 The CW Spotting process utilizes the Spot tone or the

Tuning Offset Indicator. The actual offset pitch is set by Menu item “ offset pitch may be set to any frequency between 300 Hz and 1050 Hz, in 50 Hz steps. You can either match tones audibly (using the [SPOT] button) or tune the receiver frequency so that the central red LED on the Tuning Offset indicator lights up. Note that there are 21 “dots” on the Tuning Offset Indicator, and depending on the resolution selected, the incoming CW signal may fall outside the visible range of the bar indicator, if you are not reasonably close to the proper alignment of tones.

 The displayed frequency on CW normally reflects the

“zero beat” frequency of your offset carrier. That is, if you were to listen on USB on 14.100.00 MHz to a signal with a 700 Hz offset, the “zero beat” frequency of that CW carrier would be 14.000.70 MHz; the latter frequency is what the FT-950 displays, by default. However, you can change the display to be identical to what you would see on SSB by using Menu item “

CW CONVENIENCE FEATURES

USING CW REVERSE

If you experience a difficult interference situation, where an interfering station cannot readily be eliminated, you may wish to try receiving using the opposite sideband. This may move the interfering station’s frequency in a direction that may lend itself more readily to rejection.

1. To start, let’s use a typical example where you have set the CW mode (using the default “USB” injection).

2. Now be sure your mode selection is still set for VFOA, and then press the [CW] mode button once more. The “ ” and “ ” icons will appear in the display, indicating that the “LSB” injection side has now been selected.

3. To return to the normal (USB) injection side and cancel CW Reverse operation, press the [CW] mode button once more. (the “ ” and “ ” icons will appear in the display).

NOTES:

 When CW Reverse is engaged, the action of the Tun-

ing Offset Indicator will also be reversed

CW Pitch: If you tuned to an exact “zero beat” on an incoming CW signal, you could not copy it (“Zero beat” implies a 0 Hz tone). Therefore, the receiver is offset several hundreds of Hz (typically), to allow your ear to detect the tone. The BFO offset associated with this tuning (that produces the comfortable audio tone) is called the CW Pitch.

CW CONVENIENCE FEATURES

CONTEST MEMORY KEYER

The FT-950 is capable of automatically sending CW messages (as you might do in a contest). Two techniques for message storage are available: you may either send the desired message contents using your keyer paddle (“Message Memory”), or you may input the text characters using the Main Dial Tuning knob and [CLAR/VFO-B] knobs (“Text Memory”).

Message Memory

Five memory channels capable of retaining 50 characters each are provided (using the PARIS standard for characters and word length).

Example: CQ CQ CQ DE W6DXC K (19 characters)

VFO AND MEMORY SCANNING

You may scan either the VFO or the memories of the FT-950, and the radio will halt scanning on any station with a signal strong enough to open the receiver’s squelch.

VFO SCANNING

1. Set the VFO-A to the frequency on which you would like to begin scanning.

2. Rotate the [SQL] knob so that the background noise is just silenced.

3. Press and hold in the microphone’s [UP] or [DWN key for one second to start scanning in the specified direction on the VFO frequency.

ADVICE:

If you would like to begin scanning on the VFO-B frequency, press the [VFO-B(RX)] Indicator/Switch first, then press and hold in the microphone’s [UP] or

[

DWN] key for one second.

4. If the scanner halts on an incoming signal, the decimal point between the “MHz” and “kHz” digits of the frequency display will blink.

ADVICE:

 If the incoming signal disappears, scanning will re-

sume in about five seconds.

 On the SSB/CW and SSB-based Data modes, the

scanner will pause on a received signal, then will step across the signal very slowly, giving you time to stop the scan, if you like. In these modes on the VFO, the scanner does not stop, however.

5. To cancel scanning, press the microphone’s [UP] or [

DWN] key momentarily.

VFO AND MEMORY SCANNING

MEMORY SCAN

1. Set the transceiver up in the “Memory” mode by pressing the [V/M] button, if necessary.

ADVICE:

If you can not enter the “Memory” mode, check to see if the transceiver is in VFO-B mode (the green [VFO-

B(RX)] Indicator/Switch is illuminated). If so, press

the [VFO-A(RX)] Indicator/Switch to return operation to VFO-A. Now, press the [V/M] button to enter the “Memory” mode.

2. Rotate the [SQL] knob so that the background noise is just silenced.

3. Press and hold in the microphone’s [UP] or [DWN key for one second to start scanning in the specified direction.

ADVICE:

 If the scanner halts on an incoming signal, the deci-

mal point between the “MHz” and “kHz” digits of the frequency display will blink.

 If the incoming signal disappears, scanning will re-

sume in about five seconds.

4. To cancel scanning, press the microphone’s [UP] or [

DWN] key momentarily.

ADVICE:

 During Memory Group operation, only the channels

within the current Memory Group will be scanned.

 If the scan has paused on a signal, pressing the

microphone’s [UP] or [DWN] key will cause scanning to resume instantly.

 If you press the microphone’s PTT switch during scan-

ning, the scanner will halt at once. However, pressing the PTT switch during scanning will not cause transmission.

 You may select the manner in which the scanner re-

sumes while it has paused on a signal, using Menu item
