Operating Manual
Power Connection
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: and
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, but the wiring configuration of the other manufacturer’s plug
may be different from the specified for your transceiver. Serious damage can be caused
if improper DC connections are made; consult with a qualified service technician when
in doubt.
Caution: Permanent damage can result 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.
Extending the Front Feet
In order 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 feel should now be locked in the retracted position.
Adjusting the Main Tuning Dial Torque

Installation and Interconnections
Antenna Considerations
The FT-950 is designed for use with any antenna system providing a 50 Ohm resistive
10
Vertex Standard Co., Ltd.
FT-950
Operating Manual
impedance at the desired operating frequency. While minor excursions from the
50-Ohm specification are of no consequence, the transceiver’s Automatic Antenna
Tuner may not be able to reduce the impedance mismatch to an acceptable value if the
Standing Wave Ratio (SWR) present at the Antenna jack is greater than 3:1.
Every effort should, therefore, be made to ensure that the impedance of the antenna
system utilized with the FT-950 be as close as possible to the specified 50-Ohm value.
Note that the “G5RV” type antenna does not provide a 50-Ohm impedance on all HF
Amateur bands, and an external wide-range antenna coupler must be used with this
antenna type.
Any antenna to be used with the FT-950 must, ultimately, be fed 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 so as to ensure proper antenna
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.
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
11
Vertex Standard Co., Ltd.
FT-950
Operating Manual
into the ground. If multiple ground rods are used, they should be positioned in a “V”
configuration, and bonded together at the apex of the “V” which is nearest the station
location. Use a heavy, braided cable (such as the discarded shield from type RG-213
coaxial cable) and strong cable clamps to secure the braided cable(s) to the ground rods.
Be sure to weatherproof the connections to ensure many years of reliable service. Use
the same type of heavy, braided cable for the connections to the station ground bus
(described below).
Inside the station, a common ground bus consisting of a copper pipe of at least 25 mm
(1”) diameter should be used. An alternative station ground bus may consist of a wide
copper plate (single-sided circuit board material is ideal) secured to the bottom of the
operating desk. Grounding connections from individual devices such as transceivers,
power supplies, and data communications devices (TNCs, etc.) should be made directly
to the ground bus using a heavy, braided cable.
Do not make ground connections from one electrical device to another, and thence to
the ground bus. This so-called “Daisy-Chain” grounding technique may nullify any
attempt at effective radio frequency grounding. See the drawing below for examples of
proper grounding techniques.
Inspect the ground system--inside the station as well as outside--on a regular basis so
as to ensure maximum performance and safety.
Besides following the above guidelines carefully, note that household or industrial gas
lines must never be used in an attempt to establish an electrical ground. Cold water
pipes may, in some instances, help in the grounding effort, but gas lines represent a
significant explosion hazard, and must never be used.
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.
Use a short, thick, braided cable to connect your station equipment to the buried
ground rod (or alternative earth ground system).
Advice:
Do not position this apparatus in a location with direct exposure to sunshine.
Do not position this apparatus in a location exposed to dust and/or high humidity.
Ensure adequate ventilation around this apparatus, so as to prevent heat build-up
and possible reduction of performance due to high heat.
12
Vertex Standard Co., Ltd.
FT-950
Operating Manual
Do not install this apparatus in a mechanically-unstable location, or where objects
may fall onto this product 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 cable 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 input jack.
Be absolutely certain to install your transmitting antenna(s) such that they cannot
possibly come in contact with TV/FM radio or other antennas, or with outside
power or telephone lines.
Connection of Microphone and Headphone
Key, Keyer, and Computer-Driven Keying Interconnections
The FT-950 includes a host of features for the CW operator, the functions of which will
be detailed in the “Operation” section later. Besides the built-in Electronic Keyer, two
key jacks are provided, one each on the front and rear panels, for convenient
connection to keying devices.
The Menu system allows 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 F-TYPE” for paddle input,
while connecting the rear panel’s KEY jack to the keying line from your personal
computer (which emulates a “straight key” for connection purposes), 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 +5V DC, and key-down current is approximately 1 mA. When
connecting a key or other device to the KEY jacks, use
only
a 3-pin (“stereo”) 1/4” phone
plug; a 2-pin plug will place a short between the ring and (grounded) shaft of the plug,
resulting in a constant “key-down” condition in some circumstances.
VL-1000 Linear Amplifier Interconnections
Be sure that both the FT-950 and VL-100 are turned off, then follow the installation
recommendations contained in the illustration.

Operating Manual
Note:
Please refer to the VL-1000 Operating Manual for details regarding amplifier
operation.
Please do not attempt to connect or disconnect coaxial cables when your hands are
wet.
About the CONTROL Cable
The VL-1000 may be operated with the FT-950 whether or not the CONTROL Cable is
connected; however, the CONTROL Cable allows you to tune up the amplifier
automatically by just pressing the [F SET] or [TUNE] key on the VL-1000, so as to
transmit a carrier for tuning purposes.
Set the front panel’s INPUT switch to the “INPUT2”.
To link the FT-950 and VL-1000 Power switches, set the VL-1000 REMOTE switch to
the ON position.
Interfacing to Other Linear Amplifiers
The TX GND OUT pin (pin 2) of the LINEAR jack is a transistor “open collector” circuit,
capable of handling positive amplifier relay coil voltages of up to +60VDC at 200 mA or
+30 VDC at 1 A. If you plan on using 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.
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, nor 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.

Front Panel Controls & Switches
1. [POWER] Switch
Press and hold in this switch for two seconds to turn the transceiver on. Press and hold
in this switch for two seconds, similarly, to turn the transceiver off.
2. [ANT 1-2] Switch
Pressing this selects either the ANT 1 or 2 jack on the rear panel, and allows
convenient antenna switching at the press of button. The selected antenna jack is
indicated at the Block Diagram Display in the display.
3. [TUNE] Switch
This is the on/off switch for the FT-950’s Automatic Antenna Tuner.
Pressing this button momentarily places the antenna tuner in line between the
transmitter final amplifier and the antenna jack (“TUNER” icon will appear in the
display). Reception is not affected.
Pressing and holding in this button for two seconds, while receiving in an amateur
band, activates the transmitter for a few seconds while the automatic antenna tuner
rematches the antenna system impedance for minimum SWR. The resulting setting is
automatically stored in one of the antenna tuner’s 100 memories, for instant automatic
recall later when the receiver is tuned near the same frequency.
Pressing this button momentarily, while the Tuner is engaged, will take the Automatic
Antenna tuner out of the transmit line.
Note: When the Automatic Antenna Tuner is tuning itself, a signal is being transmitted.
Therefore, be absolutely certain that an antenna or dummy load is connected to the
selected antenna jack before pressing and holding in the [TUNE] button to start
antenna tuning.
4. [MOX] Switch
Pressing this button engages the PTT (Push to Talk) circuit, to activate the transmitter

DLY”, and “116 TGEN ANTI VOX”. By proper adjustment of these controls, hands-free
voice-actuated operation is possible.
6. [MONI] (Monitor) Switch
This button enables the transmit monitor in SSB, CW, AM, and FM modes. While
activated, the “MONI” icon appears in the display. Adjustment of the Monitor level is
accomplished using the [MONI] knob.
Advice: When using headphones, the Monitor is highly useful for making adjustments
to the Parametric Equalizer or other voice quality adjustments, because the voice
quality heard in the headphones is such a “natural” reproduction of the transmitted
audio quality.
7. [PROC] (Processor) Switch
This button enables the Parametric Microphone Equalizer and Speech Processor for
SSB/AM transmission. When the Parametric Microphone Equalizer is activated, the
“MIC EQ” icon appears in the display. When the Speech Processor is activated, the
“MIC EQ” and “PROC” icons appear in the display. Adjustment of 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 (DMU-2000) 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.
8. [SPOT] Switch
This button turns on the CW receiver spotting tone; by matching the SPOT tone to that
16
Vertex Standard Co., Ltd.
FT-950

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 indicate at the frequency display area of the display
while this button is pressed.
9. [BK-IN] Switch
This button turns the CW break-in capability on and off. While CW break-in is
activated, the “BK-IN” icon appears in the display.
10. [KEYER] Switch
This button toggles the internal CW keyer on and off. While activated, the “KEYER”
icon appears in the display. The Keyer sending speed is adjusted via the front panel’s
[SPEED] knob and the CW Hang Time is adjusted via the Menu item “044 A1A
DELAY”.
11. [AGC] Switch
This button selects the AGC characteristics for the receiver. Available selections are
FAST, MID, SLOW, or AUTO, and the “AGC” icon will change according to the AGC
characteristics selected.
Press the [AGC] button repeatedly to select the desired receiver-recovery time constant.
Press and hold in the [AGC] button for two seconds to disable the AGC (for testing or
weak-signal reception).
Advice:
The Attenuator may be used in conjunction with the [IPO] button to provide two
stages of signal reduction when an extremely strong signal is being received.
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.
12. PHONES Jack
A 1/4-inch, 3-contact jack accepts either monaural or stereo headphones with 2- or
3-contact plugs. When a plug is inserted, the loudspeaker is disabled.
Note: When wearing headphones, we recommend that you turn the AF Gain levels
down to their lowest settings before turning power on, to minimize the impact on your
hearing caused by audio “pops” during switch-on.

Basic Operation: Receiving on Amateur Bands
Before turning on main power, please verify the following items once more.
Have you made all ground connections securely? See page ?? for details.
Do you have your antenna(s) connected to the rear-panel Antenna jack(s)? See
page ?? for details.
Is your microphone (and/or key or paddle) connected? See page ?? for details.
If using a linear amplifier, have all interconnections been successfully completed?
See page ?? for details.
Please rotate the [AF GAIN] control to fully counter-clockwise positions, to avoid a
loud blast of audio when the transceiver turns on. See page ?? for details.
Here is the typical start-up procedure for normal operation:
1. Turn on the external DC power supply.
2. Press and hold in the front-panel [POWER] switch for two seconds to turn the
transceiver on. After about five seconds (ten seconds if the optional µTuning 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

34
Vertex Standard Co., Ltd.
Operating Manual
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 VFOs by successive, momentary presses of the [14]
MHz band button. Each Amateur band button may similarly have up to three
frequency/mode settings applied.
If you press the [BAND] button (imbedded LED will glow orange) located in the
left of the [CLAR/VFO-B] knob, the [CLAR/VFO-B] knob may be used as a band
selection knob.

FT-950
frequency navigation 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 connected, or one RX-only antenna.
Advice: Once you have made your antenna selection, that antenna is
“remembered” by the microprocessor in conjunction with the VFO register in use
when you chose that particular antenna.
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
[SSB] 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 ??.
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]
35
Vertex Standard Co., Ltd.

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 steps, one “normal” and one “fast”, are available on each operating mode.
Pressing the [FAST] button engages the “Fast” tuning selection.
It is possible to separate the frequency change over one dial rotation, only
while operating on the CW mode, using the Menu items “084 TUN DIALSTP”
and “085 TUN CW FINE”. See page ??
If you want to navigate quickly, so as to effect rapid frequency change, there
are several techniques available:
• Direct keyboard entry of the frequency (see page ??).
• Use the [CLAR/VFO-B] knob to tune in 1 MHz steps (see page ??).
• Use the microphone’s [UP]/[DWN] scanning keys, if your microphone is so
equipped (see page ??).
Operation on 60-Meter (5 MHz) Band (U.S. version only)
The FT-950 includes the capability for transmission and reception on the five spot
frequencies assigned to the Amateur Service in the United States. To operate on the 5
MHz band:
1. Press the [V/M] button once to enter the “Memory” mode; the “MR” icon will
appear in the display and a memory channel number will appear on the
Multi-Display Window in the display.
Advice: If you can not enter the “Memory” mode, check see if the green
[VFO-B(RX)] Indicator/Switch is illuminated. If so, pressing the [VFO-A(RX)]
Indicator/Switch will cause the green [VFO-B(RX)] Indicator/Switch to go out. Now,
press the [V/M] button to enter the “Memory” mode.
2. Press the [MCH] button located on the bottom right of the [CLAR/VFO-B] knob.
The LED imbedded in the button will glow orange to signify that rotation of the

[CLAR/VFO-B] knob will allow selection the memory channel.
3. Memory channels “US1” through “US5” are pre-programmed, at the factory, with
the permitted frequencies in the 5 MHz band, and the USB mode is automatically
selected on these channels.
4. To exit from 60-meter operation and return to the VFO mode, just press the [V/M]
button.
Note: The frequencies and operating mode for 5 MHz band operation are fixed, and
may not be changed.
CLAR (Clarifier) Operation (VFO-A)
The [TX CLAR], [RX CLAR], [CLEAR] buttons and [CLAR/VFO-B] knob are used to
offset either the receive, transmit, or both frequencies from their settings on the VFO-A
frequency (the Clarifier does not affect the VFO-B, however). The 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
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 ±9.990 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 application of the programmed
offset from the receive and/or transmit frequencies. To clear out the programmed
Clarifier offset altogether, and reset it to “zero,” press the [CLEAR] button. The
programmed offset is displayed in the small multi-channel window of the frequency
±9.990 kHz) without
display.
TXCLAR
Without changing the receive frequency, you may alternatively apply the Clarifier
offset to the transmit frequency (typically, for “split” DX pile-ups). See page ?? for
details.

Using the VFO-B
The VFO-B works in a similar manner to the VFO-A, which you should be familiar by
now. However, the VFO-B frequency selects by the [CLAR/VFO-B] knob instead of the
Main Tuning Dial knob. The VFO-B provides simple split (transmit/receive) frequency
operation via the combination of the green [(VFO-A)RX] Indicator/Switch, red
[(VFO-A)TX] Indicator/Switch, green [(VFO-B)RX] Indicator/Switch, and red
[(VFO-B)TX] Indicator/Switch or [SPLIT] button. See page ?? for details for the
Split-Frequency Operation.
The frequency and mode data can be transferred from the VFO-A to the VFO-B by
pressing the [A>B] button, but don’t forget that this will overwrite any settings that
were in the VFO-B previously. Also, the contents of the two VFOs can be swapped (with
no loss of data) by pressing the [A>B] button.
Most interference-fighting circuitry which is described later can also be used on
VFO-B.
About the only things you can not do with the VFO-B (that you can with the VFO-A),
are store the contents directly into a memory and set the Clarifier. For these functions
you need to swap the VFO-B with the VFO-A by pressing the [A<>B] button, then store
the contents into the memory or set the Clarifier.
“MY Bands” Operation
When operating on an Amateur Band, it is possible to use the [BAND] buttons to

Band Stack Operation
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.

The frequency display will return to the main display field.
Important Note:
Set to match the starting point of your rotator control indicator needle via the
Menu item “011 DISP RTR STU”. The default setting is zero (north). If your
controller starting point is south, the Menu item “011 DISP RTR STU” must be set
