ABOUT THIS MANUAL . . .
The FT-950 is a leading-edge transceiver with a number of new and exciting features, some of which may be unfamiliar to
you. In order to gain the most enjoyment and operating efficiency from your FT-950, we recommend that you read this
manual in its entirety, and keep it handy for reference as you explore the many capabilities of your new transceiver.
Before using your FT-950, be sure to read and follow the instructions in the “Before You Begin” section of this manual.
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 exceptional 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 FTDX9000 transceiver, 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.
FT-950 OPERATING MANUAL
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.

BEFORE YOU BEGIN
EXTENDING THE FRONT FEET
To elevate the front panel for easy viewing, the front left and right feet of the bottom case may be extended.
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.

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 current 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 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.

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.

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 separation 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 “037 A1A FTYPE” for paddle input, and also connect the keying line from your personal computer (which emulates a “straight key”),
to the rear panel KEY jack, and configure the rear panel jack using Menu item “039 A1A R-TYPE”.
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 LINEAR 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.
Page 14
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.

[MOX] Switch
[SPOT] Switch
Pressing this button engages the PTT (Push to Talk)
circuit, to activate the transmitter (the LED inside this
button will glow red). It must be turned off (the red
LED will be off) for reception. This button replicates
the action of the Push to Talk (PTT) switch on the microphone. When engaging the [MOX] button, or otherwise causing a transmission to be started, be certain
you have either an antenna or 50-Ohm dummy load
connected to the selected Antenna jack.
This button turns on the CW receiver spotting tone; by
matching the SPOT tone to that of the incoming CW
signal (precisely the same pitch), you will be “zero
beating” your transmitted signal on to the frequency of
the other station.
The offset tone frequency will be indicated in the frequency display area of the display while this button is
pressed.

the Processor level is accomplished via the Menu item
“109 TGEN PROCLVL”.
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).
When the optional Data Management Unit (DMU2000) is connected, you may use the Audio Scope/
Oscilloscope page to help you adjust the setting of
the compression level of the Speech Processor for
optimum performance using your voice and microphone.

FT-950 OPERATING MANUAL
Page 29
BASIC OPERATION:RECEIVING ON AMATEUR BANDS
Here is the typical start-up procedure for normal operation:
[POWER] Switch
[ANT 1-2] Switch
[VFO-A(RX)] Button
Main Tuning Dial Knob
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 volume 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 [( VFOA)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.
Page 30
[BAND] Button [MODE] Button
[AF GAIN] Knob
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 selection 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 imbedded LED will glow orange, and the [CLAR/VFOB] 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.
FT-950 OPERATING MANUAL
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 PITCH”), even though the actual tone
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 FRQDISP”, described on page 112.
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 “084 TUN DIALSTP” and “085
TUN CW FINE”. See page 116.
If you want to navigate rapidly, so as to effect rapid
frequency change, there are several techniques
available:
Direct keyboard entry of the frequency (see page
39).
Use the [CLAR/VFO-B] knob to tune in 1 MHz
steps (see page 39).
Use the microphone’s [UP]/[DWN] scanning
keys, if your microphone is so equipped (see
page 39).

FT-950 OPERATING MANUAL
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
±9.999 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.
[CLEAR] Button
[TX CLAR] Button
Multi-Display Window [RX CLAR] Button
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 application 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 frequency. 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.
[CLAR/VFO-B] Knob
TXCLAR
Alternately, You may apply the Clarifier offset to
the transmit frequency, without changing the receive
frequency (typically, for “split” DX pile-ups). See
page 68 for details.
The Tuning Offset Indicator provides a graphical representation of the Clarifier offset.
In the factory default setting On CW, the Tuning Offset Indicator is used for CW Center
Tuning, instead of Clarifier Offset. If you wish to change this so that the Clarifier Offset
is also displayed on CW, use the following procedure:
1. Press the [MENU] button to enter the Menu mode.
2. Rotate the [SELECT] knob to select Menu item
“006 DISP BAR SEL”.
ADVICE:
Press the [SELECT] knob momentarily to toggle

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

Keyboard Frequency Entry
You may enter operating frequencies directly into the current VFO, using the front panel [BAND] key buttons.
Example: Enter 14.250.00 MHz
1. Press the [ENT] button to
engage the direct frequency
entry process. Now, beginning with the first digit of
the frequency (the leftmost
digit), we will enter the required digits of the frequency.
2. Press, in order, the digits of the operating frequency,
using the [BAND] buttons (the frequency entry digit
or decimal point is printed on the right side of the buttons). In this example, enter
[1.8(1)] [10(4)] [GEN(.)] [3.5(2)] [14(5)] [50(0)] [50(0)] [50(0)] [50(0)]
The decimal point after the “MHz” portion of the frequency must be entered, but no decimal point is required after the “kHz” portion.
3. Press the [ENT] button once more. A short “beep” will
confirm that the frequency entry was successful, and

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) (SEE PAGE 45)
IF NOTCH (SEE PAGE 51)
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.
The IF Notch filter is a high-Q notch filter that can significantly reduce, if not eliminate, an interfering carrier.
CONTOUR Filter (SEE PAGE 47)
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 (SEE PAGE 48)
The passband center frequency of the IF DSP filter may
be moved up or down by adjusting this control.
DNF (Digital Notch filter) (SEE PAGE 52)
When multiple interfering carriers are encountered during
reception, the Digital Notch Filter can significantly reduce
the level of these signals.
DNR (Digital Noise Reduction) (SEE PAGE 52)
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 (SEE PAGE 55)
The AGC system is highly adaptable to changing signal
and fading characteristics, making reception possible under the most difficult conditions.
IF WIDTH (SEE PAGE 49)
The width of the IF DSP filtering may be adjusted using
this control.

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.
ADVICE:
The tuning position of the µ-Tune filter will appear
in the Tuning Offset Indicator on the display for
three seconds, and the “

2. Rotate the [SELECT] knob to peak the response (background noise) or reduce interference.
ADVICE:
You may observe the relative peak point of the µTune filter in the Tuning Offset Indicator on the
display, while tuning the [SELECT] knob.
The amount of change in the center frequency of
the µ-Tune filter, when rotating the [SELECT]
knob by one click, can be configured using Menu

If you have performed manual adjustment of the µTune filter center frequency, you may press the
[CLEAR] button to re-center the filter response on
your current operating frequency.
3. Press the [µ-TUNE] button (or [SELECT ] knob)
momentarily to disengage the µ-Tune filter; the “
”
icon will be changed to “
” in the FLT column of
the Block Diagram Display on the display. In this mode,
only the fixed bandpass filter for the current band will
be engaged.
ADVICE:
Alternate presses of the [µ-TUNE] button or the [SELECT] knob, will switch the µ-Tune filter between on
or off.
Page 42
TUNING OFFSET INDICATOR
ADVICE:
The µ-Tune Filter selection will be memorized independently on each VFO stack of the VFO-A and VFOB.
You may change the indication of the Tuning Offset
Indicator to display the center frequency of the µ-Tune
filter continuously while the µ-Tune filter is activated.
This is Menu item “006 DISP BARSEL”. See Box on
the next page for details of the setting.
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.
FT-950 OPERATING MANUAL
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 reception 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.

The selected receiver RF preamplifier will be indicated in
the IPO column of the Block Diagram Display on the display.
BLOCK DIAGRAM DISPLAY
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.

R.FLT (ROOFING FILTERS)
Narrow-band Roofing Filters of 15 kHz, 6 kHz, and 3 kHz bandwidths are provided in the first IF, right after the first mixer.
These filters provide protection for the 2nd mixer, DSP, and other circuitry that follow and can dramatically improve
reception on a very crowded band (during a contest, etc.). Typically, the AUTO selection mode is satisfactory for most
operating situations, but in an extremely crowded phone band you may wish to select, for example, the 3 kHz roofing filter
for SSB operation.
Press the [R.FLT] button to toggle the Roofing Filter selection.

QUICK POINT:
The “AUTO” selection of the Roofing Filter is based on
the operating mode. However, you may override the automatic selection, if band conditions warrant a different (usually, a tighter) selection.
FT-950 OPERATING MANUAL
TERMINOLOGY:
A “Roofing Filter,” as its name implies, places a “Roof”
over the receiver’s IF system bandwidth. This “Roof” protects the circuitry downstream from the first mixer from
interference, just as a roof on a house protects the contents
from rain and snow.

ADVICE:
Alternate presses of the [CONT] button or the [SELECT] knob, will switch the Contour filter between
on or off.
CONTOUR GAIN “NULL”
CONTOUR GAIN “PEAK”
ADVICE:
The Contour filter selection will be memorized independently on each VFO stack of VFO-A and VFO-B.
The Contour filter level (either a null or a peak) may
be adjusted using Menu item “069 RGEN CNTR LV”.
The factory default setting is for a null of –15 (dB).
The bandwidth over which the Contour filter effect is
applied may be adjusted using Menu item “070 RGEN
CNTR WI”. The factory default setting is 10.
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 “069 RGEN CNTR
LV”, referenced above) in the passband. Counterclockwise 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.

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.

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.
1. Press the [SHIFT] button. The LED inside the [SHIFT]

The IF Bandwidth will be memorized independently on
each VFO stack of VFO-A and VFO-B.
Referring to Figure “B”, you can see the default
bandwidth on the SSB mode by pressing the
[CLEAR] button.
By rotating the [SELECT(WIDTH)] knob to the
left, the bandwidth will narrow (see Figure “A”,
while rotation of the [SELECT(WIDTH)] knob to
the right, as depicted in Figure “C”, will increase
the bandwidth.

The IF SHIFT and Variable IF WIDTH features
together form a very effective interference-fighting filtering system.
For example, in Figure “A”, you can see how interference has appeared both on the high and low sides
of the desired signal. Press the [WIDTH] button
then rotate the [SELECT(WIDTH)] knob, the interference from one side can be eliminated (Figure
“B”). Next, press the [SHIFT] button and rotate
the [SELECT(SHIFT)] knob to re-positioning the
passband (Figure “C”), the interference on the opposite side can be removed, without re-introducing the interference previously eliminated in Figure “B”.

DIGITAL NOTCH FILTER (DNF) OPERATION
The Digital NOTCH Filter (DNF) is an effective beat-canceling filter that can null out a number of interfering beat notes
inside the receiver passband. Because this is an Auto-Notch feature, there is no adjustment knob associated with this filter.
ADVICE:
If a very strong interfering carrier is encountered, we recommend you first use the IF NOTCH filter, as it is the most

DIGITAL NOISE REDUCTION (DNR) OPERATION
The Digital Noise Reduction (DNR) system is designed to reduce the level of random noise found on the HF and 50 MHz
bands, and it is especially effective during SSB operation. By setting the Menu item “072 RGEN DNR”, any of 15 different
noise-reduction algorithms can be selected; each of these algorithms was created for dealing with a different noise profile,
and you will want to experiment with the DNR system to find the best setting according to the noise currently being

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.
[RF GAIN] Knob
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 Attenuator 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.

TOOLS FOR COMFORTABLE AND EFFECTIVE RECEPTION
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.
Block Diagram Display
[AGC] Button
BLOCK DIAGRAM DISPLAY
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:

ADVICE:
The AGC selection will be memorized independently

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.
FT-950 OPERATING MANUAL
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.

GAIN] knob is turned.
6. Release the PTT switch at the end of your transmission. The transceiver will return to the receive mode.
FT-950 OPERATING MANUAL
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.
In the SSB mode, you may set the desired power output via the Menu item “111 TGEN TX PWR”. The
adjustment range is between 5 Watts and 100 Watts.
You should always use the minimum power necessary
to maintain reliable communications.
When performing “on air” tests (such as the setup of
microphone gain), be sure to check the frequency before transmitting, to avoid interference to others who
may already be using the frequency.
Four techniques for exercising Transmit/Receive control are provided on the FT-950. You may choose the
technique(s) that best suit your operating needs:
Pressing the microphone PTT switch will engage
the transmitter.
The rear panel PTT jack may be connected to a
foot switch or other manual switching device in
order to engage the transmitter.
Pressing the front panel [MOX] button will lock
the transmitter on. Press the [MOX] button again
to return to receive.
The VOX (Voice Operated Xmit) circuit will engage the transmitter automatically when you speak
into the microphone. For details of VOX operation, see page 66.

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.
Page 58
[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

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 “111 TGEN TX PWR”, so you will not
cause interference to other users while making adjustments.
ADVICE:
We recommend that you connect a dummy load to
one of the Antenna jacks, and monitor your signal
on a separate receiver, to prevent interference to
other users.
You will have the best chance of hearing the effects of adjustments if you wear headphones (connected to the monitor receiver) while listening to
your transmitted signal.

5. Press the [MENU] button momentarily. The Menu list
will appear in the display.
6. Rotate the [SELECT] knob to find the “EQ” Menu
area, containing Menu items “091” through “099”;
these parameters apply to the adjustment of the Parametric Microphone Equalizer when the speech processor is disabled. Menu items “100” through “108” apply to the adjustment of the Parametric Microphone
Equalizer when the speech processor is engaged.
ADVICE:
If you do not find the Menu item number, press the
[SELECT] knob momentarily to switch the Menu item
name to the Menu item number.
7. Rotate the [CLAR/VFO-B] knob to perform adjustments to a particular Menu item.

8. Close the PTT switch, and speak into the microphone
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 “064
J3E TX BPF”.
ADVICE:
Press the [SELECT] knob to toggle the Menu item
display between “064 J3E” and “TX BPF”.
3. Rotate the [CLAR/VFO-B] knob to select the desired
bandwidth. The available selections are 1-30 (1003000 Hz), 1-29 (100-2900 Hz), 2-28 (200-2800 Hz),
3-27 (300-2700 Hz), and 4-26 (400-2600 Hz). The
default is 3-27 (300-2700 Hz). A wider bandwidth will
provide greater fidelity. A narrow bandwidth will compress the available transmitter power into less spectrum, resulting in more “talk power” for DX pile-ups.
4. Press and hold in the [MENU] button for one second
to save the new setting and exit to normal operation.
ADVICE:
The Transmit Monitor function is a very helpful way
to confirm the effect changing the bandwidth will have
on fidelity. By Pressing the [MONI] button and then
adjusting the [MONI] knob for a comfortable listening
level while you are transmitting, you will be able to
hear the difference in sound quality as you make
changes.
When the optional DMU-2000 Data Management Unit
is connected, you may verify the effect of your adjustments of the transmitted bandwidth by observing the
Audio Scope on the “Oscilloscope” page.

SPLIT OPERATION USING THE TX CLARIFIER
For split TX/RX operation in “casual” pile-ups, where the split is less than 10 kHz, the TX Clarifier (Offset Tuning) feature
may be utilized.
1. Press the [TX CLAR] button. The “TX” icon will appear in the Multi-Display Window
in the display.
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 ±9.999 kHz may
be set.
3. To exit from TX Clarifier operation, press the [TX
CLAR] button once more. The “TX” icon will disappear 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.

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.

Full break-in (also known as “Full QSK”) involves very fast switching between transmit and receive, incoming
signals may be heard between the dots and dashes as you send them. This allows you to hear a station that suddenly
starts transmitting on your frequency, while you are in the midst of a transmission.

FT-950 OPERATING MANUAL
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.
[SPOT] Button
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 utilized for CW frequency adjustment, as well. Its configuration is set via Menu item “006 DISP BAR SEL”
at the factory, and the Tuning Offset Indicator is already set to the “C-tn” selection.
FT-950 OPERATING MANUAL
QUICK POINTS:
The CW Spotting process utilizes the Spot tone or the
Tuning Offset Indicator. The actual offset pitch is set
by Menu item “045 A1A PITCH” (see page 112). The
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 “047
A1A FRQDISP” and setting it to “dIr” instead of the
default “OFSt” setting.
Page 75
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 Tuning Offset Indicator will also be reversed
When the incoming signal pitch tone is properly
aligned, the central red marker lights up whether or
not CW Reverse is engaged.
Retune: Shift to Lower Frequency
[MODE] Button
In the illustration, Figure “A” demonstrates the normal CW injection setup, using the USB side. In

TERMINOLOGY:
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.

OPERATION ON ALASKA EMERGENCY FREQUENCY: 5167.5 KH (U.S. VERSION ONLY)
Z
Section 97.401(d) of the regulations governing amateur radio in the United States permit emergency amateur communications on the spot frequency of 5167.5 kHz by stations in (or within 92.6 km of) the state of Alaska. This frequency is only
to be used when the immediate safety of human life and/or property are threatened, and is never to be used for routine
communications.
The FT-950 includes the capability for transmission and reception on 5167.5 kHz under such emergency conditions via the
Menu system. To activate this feature:
1. Press the [MENU] button to enter the Menu mode.
2. Rotate the [SELECT] knob to select Menu item “118
TGEN EMRGNCY”.
ADVICE:
Press the [SELECT] knob momentarily to toggle the
Menu item display between “118 TGEN” and
“EMRGNCY”.
3. Rotate the [CLAR/VFO-B] knob to select “EnA (Enable).”
4. Press and hold in the [MENU] button for one second
to save the new setting and exit to normal operation.
Emergency communication on this spot frequency is
now possible.
5. Press the [V/M ] button, as necessary, to enter the
Memory mode. Press the [MCH] button, then rotate
the [CLAR/VFO-B] knob to select the emergency
channel (“EUS”), which is found between channels
“US5” and “01”).
NOTE:
The receive-mode CLARIFIER functions normally
while using this frequency, but variation of the transmit frequency is not possible. Activation of “118 TGEN
EMRGNCY” does not enable any other out of amateur
band capability on the transceiver. The full specifications of the FT-950 are not necessarily guaranteed on
this frequency, but power output and receiver sensitivity should be fully satisfactory for the purpose of emergency communication.
If you wish to disable operation capability on the Alaska
Emergency Frequency, repeat the above procedures,
but set “118 TGEN EMRGNCY” to “diS” in step 3.
In an emergency, note that a half-wave dipole cut for
this frequency should be approximately 45’3” on each
leg (90’6” total length). Emergency operation on
5167.5 kHz is shared with the Alaska-Fixed Service.
This transceiver is not authorized for operation, under
the FCC’s Part 87, for aeronautical communications.

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 resume 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-B(RX)] Button

FT-950 OPERATING MANUAL
PMS (PROGRAMMABLE MEMORY SCANNING)
To limit scanning (and manual tuning) within a particular frequency range, you can use the Programmable Memory Scanning (PMS) feature, which utilizes nine special-purpose memory pairs (“P1L/P1U” through “P9L/P9U”). The PMS feature is especially useful in helping you to observe any operating sub-band limits, which apply to your Amateur license class.
1. Store the Lower and Upper tuning/scanning limit frequencies into the memory pair “P1L” and “P1U”, respectively, or any other “L/U” pair of memories in the
special PMS memory area. See page 92 for details regarding memory storage.
2. Press the [V/M] button to enter the “Memory” mode.
ADVICE:
If you can not enter the “Memory” mode, check to see
if the transceiver is in VFO-B mode (the green [VFOB(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.
3. Press the [MCH] button momentarily. The imbedded
LED inside the switch will glow orange.
4. Rotate the [CLAR/VFO-B] knob to select memory
channel “P1L” or “P1U”.
5. Rotate the [SQL] knob so that the background noise is
just silenced.
6. Turn the Main Tuning Dial knob slightly (to activate
memory tuning). Tuning and scanning are now limited
to the range within the P1L/P1U limits until you press
the [V/M] button to return to memory channel or VFO
operation.
7. 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 decimal point between the “MHz” and “kHz” digits of
the frequency display will blink.
If the incoming signal disappears, scanning will resume 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. However, in these
modes on the VFO, the scanner does not stop.
If the scan has paused on a signal, pressing the
microphone’s [UP] or [DWN] key will cause scanning to resume instantly.
8. If you rotate the Main Tuning Dial knob in the opposite direction from the current scanning direction (in
other words, you rotate the dial to the left when scanning toward a higher frequency), the direction of the
scan will reverse.
9. If you press the microphone’s PTT switch during scanning, the scanner will halt at once. Pressing the PTT
switch during scanning will not cause transmission.

the “
” and “
” icons are shown on the display, the FT-950 is configured for Packet operation in the “USB” mode.
2. When the “transmit” command is received from the
TNC, the transmitter of the FT-950 will automatically
be engaged. Likewise, the command to return to receive will cause the radio to revert to the receive mode.
Page 100
ADVICE:
If you need to adjust the output level from the “DATA
OUT” pin (pin 5) of the RTTY/PKT jack on the rear
panel of the transceiver, please use Menu item “051
DATA OUT LVL”. For the input level from the TNC, as
applied to the DATA IN pin (pin 1) of the RTTY/PKT
jack, please use Menu item “050 DATA DT GAIN”.
During Packet operation via the rear panel’s RTTY/
PKT jack, the front panel MIC jack is cut off, so you
won’t have a “live microphone” problem during data
operation.
NOTE:
If you anticipate making data transmissions of longer than
a few minutes, we recommend that you reduce the transmitter power to 1/3 ~ 1/2 of its normal maximum via the
Menu item “111 TGEN TX PWR”.

BASIC SETUP
1. To engage RTTY operation using “LSB” injection,
which is generally used in the Amateur service. Press
the [RTTY/PKT ] button repeatedly until both the
“
” and “
” icons appear on the display.
2. To switch to USB-side injection in RTTY, press and
hold in the [RTTY/PKT] button. Both the “
” and
“
” icons will appear on the display.
3. When you begin typing on your TU or computer keyboard, the command to transmit should automatically
be sent to the transceiver, causing it to enter the transmit mode.
NOTE:
If you anticipate making data transmissions of longer than
a few minutes, we recommend that you reduce the transmitter power to 1/3 ~ 1/2 of its normal maximum via the
Menu item “111 TGEN TX PWR”.
ADVICE:
If you need to adjust the output level from the “DATA
OUT” pin (pin 5) of the RTTY/PKT jack on the rear
panel of the transceiver, please use Menu item “061
RTTY OUT LVL”. For the input level from the TU, there
is no adjustment of the FSK input level (Pin 4) of the
RTTY/PKT jack. Please make any needed level adjustments at the TU side.
FT-950 OPERATING MANUAL
The Mark/Space Shift utilized in most Amateur RTTY
operation is 170 Hz. Other shifts may be configured,
however, using Menu item “062 RTTY SHIFT”. The
FT-950 is set up for “high tone” operation (centered
on 2125 Hz) by default, but you may configure it for
low tone (1275 Hz) operation using Menu item “063
RTTY TONE”.
You may find that you are unable to decode some RTTY
stations, even if they are of sufficient signal strength.
If this is observed, there may be a Mark/Space polarity
problem between your station and the other station. If
so, try setting Menu item “059 RTTY R PLRTY” to
“rEU” (“Reverse”) to see if that permits copy. A separate Menu Item permits reversal of your transmitter’s
Mark/Space polarity: “060 RTTY T PLRTY”.
QUICK POINT:
In the FT-950, “RTTY” is a mode defined as being an
“FSK” mode, whereby the closing and opening of a keying line (to ground) causes the Mark/Space tones to alternate. The RTTY mode is not an AFSK based mode in this
transceiver, and the AFSK output tones from a TNC will
not cause Mark/Space shifting to occur. Use the “Packet”
mode for AFSK-based Baudot and other data modes.
Page 101
MISCELLANEOUS AFSK-BASED DATA MODES
The FT-950 may also be used for a host of other SSB-based Data modes. Please set up your system using the illustration
as a guideline.

RF µTUNING KIT
The RF µTuning Kits provide 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.
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 receiver RF stages
is especially helpful in preventing IMD and blocking.

FC-40 EXTERNAL AUTOMATIC ANTENNA TUNER (FOR WIRE ANTENNA)
The FC-40 makes use of the control circuitry built into the transceiver, which allows the operator to control and monitor
automatic operation of the FC-40, which mounts near the antenna feedpoint. The FC-40 uses specially selected, thermally
stable components, and is housed in a waterproof case to withstand severe environmental conditions with high reliability.
A carefully-chosen combination of solid-state switching components and high-speed relays allows the FC-40 to match a
wide variety of antennas to within a 2:1 SWR on any amateur band frequency (160 through 6 meters), typically in less than
eight seconds. Transmitter power required for matching may be as little as 4 - 60 Watts, and matching settings are automatically stored in memory for instant recall when the same frequency range is selected later.
Please see the FC-40 Operating Manual for detailed information.
Interconnections to FT-950
After mounting the FC-40, connect the cables from the
FC-40 to the ANT and TUNER jacks on the rear panel of
the FT-950 Transceiver.

NOTE:
Please connect a good earth ground to the GND terminal of FC-40.
The carrier signal transmits continuously while tuning
is in progress. Please monitor the operating frequency
before beginning the tuning process. Be sure you are
not interfering with others who may already be using
the frequency.
It is normal to hear the sound of the relays while tuning is in progress.
If the impedance cannot be matched by the FC-40 better than 2:1, and the “
” icon blinks, the microprocessor will not retain the tuning data for that frequency, as the FC-40 presumes that you will want to
adjust or repair your antenna system to correct the high
SWR condition.
