FT-950 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 manufacturers 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 9 Vertex Standard Co., Ltd. FT-950 Operating Manual 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 itself to the right to reduce the drag or to the left to increase the drag. Available adjustment range is 120.

Important Note: When the optional Tuning Kit is connected to the FT-950, disconnect the all cables from the Tuning Kit then perform the Full Reset. 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 transceivers 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 panels 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. 13 Vertex Standard Co., Ltd. FT-950 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 panels 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. Plug/Connector Pinout Diagrams IMPORTANT NOTE:
The -TUNE and DMU connectors are special connectors for this transceiver. Please do not connect any accessory or other device not specifically approved by Vertex Standard. Failure to observe this precaution may cause damage not covered by the Limited Warranty on this apparatus. 14 Vertex Standard Co., Ltd. FT-950 Operating Manual 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-950s 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 tuners 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
(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. 15 Vertex Standard Co., Ltd. FT-950 Operating Manual 5. [VOX] Switch This button enables automatic voice-actuated transmitter switching in the SSB, AM, and FM modes. While activated, the LED inside this button glows red. The controls affecting VOX operation are via the Menu item 114 TGEN V GAIN, 115 TGEN VOX 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 Operating Manual 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 panels
[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. 17 Vertex Standard Co., Ltd. FT-950 Operating Manual 13. [METER] Switch This button determines the function of the meter during transmission. Press this button to change the meter function in the transmit mode as follows:
ALC SWR ID VDD COMP ALC Indicates the relative ALC voltage. Indicates the Standing Wave Ratio (Forward: Reflected). Indicates the final amplifier drain current. Indicates the final amplifier drain voltage. ALC:
SWR:
ID:
VDD:
COMP: Indicates the speech compressor level (SSB modes only). 14. [MIC GAIN] Knob This knob adjusts the microphone input level for (non-processed) SSB and AM transmission. Advice: If you adjust the [MIC GAIN] knob while speaking in a somewhat louder than normal voice level, watch the ALC level and adjust the [MIC GAIN] knob so that the ALC reaches just to the right edge of the ALC scale. Then, when you speak in a more normal voice level, youll be certain not to be over-driving the mic amplifier stage. 15. [SPEED] Knob This knob adjusts the keying speed of the internal CW keyer (4 ~ 60 WPM). Clockwise rotation increases the sending speed. When turning this knob while pressing the [KEYER] button, the frequency display shows the keying speed. 16. Microphone Connector This 8-pin jack accepts input from a microphone utilizing a traditional YAESU HF transceiver pinout. 17. KEY Jack This 1/4-inch, 3-contact jack accepts a CW key or keyer paddles (for the built-in electronic keyer), or output from an external electronic keyer. Pinout is shown on page ??. Key up voltage is 5 V, and key down current is 1 mA. This jack may be configured for keyer, Bug, straight key, or computer keying interface operation via Menu item 037 A1A F-TYPE (see page ??). There is another jack with the same name on the rear panel, and it may be configured independently for Internal Keyer or 18 Vertex Standard Co., Ltd. FT-950 Operating Manual pseudo-straight-key operation. Note: You cannot use a 2-contact plug in this jack (to do so produces a constant key down condition). 18. [MONI] Knob This knob adjusts the audio level of the transmit RF monitor during transmission
(relative to the [AF GAIN] knob), when activated by the [MONI] button. 19. [SQL] Knob This knob sets the signal level threshold which at the receiver audio is muted, in all modes.

34 Vertex Standard Co., Ltd. FT-950 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 bands 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.
If you press the [MHz] button (imbedded LED will glow orange) located in the left of the [CLAR/VFO-B] knob, rotation of the [CLAR/VFO-B] knob allows 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. FT-950 Operating Manual 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. Operating Mode LSB, USB, CW, RTTY, PKT(LSB) AM, FM, PKT(FM) 1 Step 10Hz [100Hz]

[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 9.990 kHz) without actually retuning, and then to activate it via the Clarifiers [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 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. 37 Vertex Standard Co., Ltd. FT-950 Operating Manual The Tuning Offset Indicator provides a graphical representation of the Clarifier offset. On CW, the Tuning Offset Indicator is used for CW Center Tuning, instead of Clarifier Offset, as the transceiver is configured at the factory. 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 to toggle the Menu item display between 006 DISP and BAR SEL. 3. Rotate the [CLAR/VFO-B] knob to select CLAr (Clarifier) (replacing the default C-tn (CW TUNING) selection). 4. Press and hold in the [MENU] button for two seconds to save the new setting and exit to normal operation. LOCK You may lock the setting of the Main Tuning Dial knob (for VFO-A frequency tuning) and the [CLA/VFO-B] knob (for VFO-B frequency tuning), to prevent accidental. To lock out the Main Tuning Dial knob and the [CLA/VFO-B] knob, just press the
[LOCK] button that is located to the right of the Main Tuning Dial knob. To unlock the Dial setting, and restore normal tuning, just press the [LOCK] button once more. DIMMER The illumination level of the display may be adjusted via the Menu item 005 DISP DIM VFD, if you desired. To adjust the illumination level:
1. Press the [MENU] button to enter the Menu mode. 2. Rotate the [SELECT] knob to select Menu item 005 DISP DIM VFD. Advice: Press the [SELECT] knob to toggle the Menu item display between 005 DISP and DIM VFD. 3. Rotate the [CLAR/VFO-B] knob to select desired illumination level. 4. Press and hold in the [MENU] button for two seconds to save the new setting and exit to normal operation. Convenience Features 38 Vertex Standard Co., Ltd. FT-950 Operating Manual
[(VFO-B)RX]
Indicator/Switch, green 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, 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 dont 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 engage the use of the [CLAR/VFO-B] knob for Amateur band selection. The My Bands feature allows you to select several Amateur bands, and make only those bands available for selection via the [CLAR/VFO-B] knob. This feature can be very useful in a contest, where the 10/18/24 MHz band are not used, or if you do not have antennas for some bands. My Bands Setup 1. Press the [MENU] button to engage the Menu mode. 2. Rotate the [SELECT] knob to select Menu item 090 TUN MY BAND. Advice: Press the [SELECT] knob to toggle the Menu item display between 090 TUN and MY BAND. 3. Rotate the [CLAR/VFO-B] knob to choose a band that you wish to skip (omit) from 39 Vertex Standard Co., Ltd. FT-950 Operating Manual the band-selection loop (when using the [CLAR/VFO-B] knob for band selection). The available choices are 1.8/3.5/5/7/10/14/18/21/24/28/50/GE (General Band). 4. Press the [ENT] button to set the omission command to ON. The E (Enable) notation at the right of the band notation will change to d (disable). 5. Repeat steps 3 and 4 to select/deselect as many bands as you like. Note: The ON command sets the selected band to be skipped, while the OFF command sets the selected band to be included in the band-selection list. Return the d notation to E to restore operation on a previously-deleted band. 6. Press and hold in the [MENU] button for two seconds to lock in the new configuration and exit to normal operation. Advice: The My Band feature affects both the VFO-A and VFO-B. My Band Operation 1. Press the [BAND] button at the left of the [CLAR/VFO-B] knob; the imbedded LED will glow orange. 2. Rotate the [CLAR/VFO-B] knob to choose the Amateur band on which you wish to operate. Only those Amateur bands that have not been skipped will appear as you scroll through the bands. To disable the My Band Operation, press the [BAND] button again; the imbedded orange LED goes out. Advice: The My Band feature affects both the VFO-A and VFO-B. 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 bands 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 MHzCW Mode, then press the [14] MHz band button;
2. Program 14.080 MHzRTTY Mode, then press the [14] MHz band button;
3. Program 14.195 MHz, SSB Mode, then press the [14] MHz band button. 40 Vertex Standard Co., Ltd. FT-950 Operating Manual With this configuration, successive momentary presses of the [14] MHz band button will allow you to toggle sequentially through these three VFOs. C.S (Custom Switch) An often-used Menu mode selection may be brought out to the front panels [C.S]
button. C.S Setup 1. Press the [MENU] button to engage the Menu mode; the Menu list will appear on the display. 2. Rotate the [SELECT] knob to select the Menu item you want to be able to access via the [C.S] button. Advice: Press the [SELECT] knob to toggle the Menu item display between Menu item number and group and Menu Function. 3. Press and hold in the [C.S] button for two seconds to lock in your selection. 4. Press and hold in the [MENU] button for two seconds to save the new configuration and exit to normal operation. Menu Selection Recall via [C.S] button Press the [C.S] button. The programmed Menu item will appear on the display. You may now rotate the
[CLAR/VFO-B] knob to change the setting of this menu item. Press and hold the
[MENU] button for two seconds, when you are done, to save the new configuration and exit to normal operation. Rotator Control Functions When using a YAESU model G-800DXA, G-1000DXA, or G-2800DXA rotator (not supplied), it is possible to control it from the front panel of the FT-950. 1. Press and hold in the [ENT] button (one of the [BAND] Switch) for two seconds. The frequency display area will change over to the Rotator Control configuration. 2. Press either the [3.5(2)] button or the [7(3)] button to rotate the antenna. Pressing the [3.5(2)] button will cause rotation to the left (counter-clockwise), while pressing the [7(3)] button will cause rotation to the right (clockwise). 3. Press the [14(5)] button or the [18(6)] button to control the speed of rotation. Pressing the [14(5)] button will cause slower rotation, while pressing the [18(6)]
button will speed up rotation. Usually, you will be using the 100% setting. 41 Vertex Standard Co., Ltd. FT-950 Operating Manual When you are through exercising rotator control, press the [ENT] button momentarily. 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 to 180. If not set properly the FT-950 display will not show the correct direction.
When the rotator control indicator needle does not indicate the precise antenna direction, adjusts the indicator needle precisely to the antenna direction via the Menu item 012 DISP RTR ADJ. More Frequency Navigation Techniques Keyboard Frequency Entry You may enter operating frequencies directly into the current VFO, using the front panel [BAND] buttons. Example: Enter 14.250.00 MHz 1. Press the [ENT] button to engage the direct frequency entry process. Now, beginning with the 10 MHz 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
(which have the frequency-entry digit or decimal point on the right side of the slash bar). 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 the new operating frequency will appear on the display. Advice: If you attempt to enter a frequency outside the operating range of 30 kHz ~ 56 MHz, the microprocessor will ignore the attempt, and you will be returned to your previous operating frequency. If this happens, please try again, taking care not to repeat the error in the frequency entry process. Using the [CLAR/VFO-B] knob You may change the current VFO frequency in 1 MHz steps. If you press the [BAND]
button located in the bottom left of the [CLAR/VFO-B] knob, the 1 MHz steps will be 42 Vertex Standard Co., Ltd. FT-950 Operating Manual applied to the current VFO frequency. The imbedded LED in the [BAND] button will glow orange in the latter case. When tuning in 1 MHz steps, clockwise rotation of the [CLAR/VFO-B] knob will increase the frequency, while counter-clockwise rotation will decrease the frequency. Using the [UP]/[DWN] buttons of the supplied MH-31B8 Hand Microphone The [UP]/[DWN] buttons on the supplied MH-31B8 Hand Microphone may also be used for manually scanning upward or downward in frequency, respectively. The microphones [UP]/[DWN] buttons utilize the tuning steps of the Main Tuning Dial knob; moreover, when the microphones [FST] button is pressed, the tuning rate increases by a factor of ten, in a manner similar to the effect of the transceivers front-panel [FST] button. Advice: In the AM and FM modes, you may independently set the tuning steps when using the [UP]/[DWN] buttons. To set new tuning steps, use Menu items 087 TUN AM STEP and 088 TUN FM STEP. 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-950s 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 ??) Three automatically-selected Roofing filters, in bandwidths of 15 kHz, 6 kHz, and 3 kHz, are provided in the 69 MHz First IF, right after the first mixer. These filters provide narrow-band selectivity to protect the following IF and DSP stages, and the filters automatically-selected bandwidths may be manually changed by the operator, if desired, for special operating circumstances. 43 Vertex Standard Co., Ltd. FT-950 Operating Manual CONTOUR Filter (See page ??) The DSP Contour filter is a unique capability providing either nulling or peaking of tunable segments of the receiver passband, so as to suppress interference or excessive frequency components on an incoming signal, or to peak those tunable frequency segments. The amount of nulling/peaking, and the bandwidth over which it is applied, are adjustable via the Menu. IF SHIFT (See page ??) The passband center frequency response of the IF DSP filtering may be adjusted using this control. IF WIDTH (See page ??) The width of the IF DSP filtering may be adjusted using this control. IF NOTCH (See page ??) The IF Notch filter is a high-Q notch filter that can significantly reduce, if not eliminate, an interfering carrier. DNF (Digital Notch filter) (See page ??) 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 ??)
(DNR) feature utilizes sixteen different The DSPs Digital Noise Reduction 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, which concurrently will allow the signal to rise up out of the noise. AGC (See page ??) The AGC system is highly adaptable to changing signal and fading characteristics, making reception possible under the most difficult conditions. ATT When extremely strong local signals or high noise can still degrade reception, you can use the [ATT] button to insert 6, 12, or 18-dB of RF attenuation in front of the RF amplifier. 44 Vertex Standard Co., Ltd. FT-950 Operating Manual 1. Press the [ATT] button several times to set the desired attenuation level, per the chart below. OFF: Attenuator is Off 6 dB: The incoming signal power is reduced by 6 dB
(Signal voltage reduced by 1/2) 12 dB: The incoming signal power is reduced by 12 dB
(Signal voltage reduced by 1/4) 18 dB: The incoming signal power is reduced by 18 dB
(Signal voltage reduced by 1/8) 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. 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 (or add more attenuation) by pressing the [ATT] button to a more 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.
-Tune Filter (Requires the optional RF Tuning Kit) The RF Tuning 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 Tuning Kit 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. 45 Vertex Standard Co., Ltd. FT-950 Operating Manual 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.
-Tune Operation 1. Press the [-TUNE] button. The LED inside the [-TUNE] button glows orange. The [SELECT] knob works as the -TUNING knob. 2. Press the [SELECT] knob to activate the -Tune filter. The tuning position of the
-Tune filter will appear in the Tuning Offset Indicator on the display. Advice:
The -Tune circuit will automatically align itself onto your operating frequency.
Remember that -Tune only operates on the 14 MHz and lower bands. 3. Rotate the [SELECT] knob to peak the response (background noise) or reduce interference. Advice:
The amount of change in the center frequency of the -Tune filter, when rotating the [SELECT] knob by one click, can be configured using Menu item 032 GENE T DIAL.
If you have performed manual adjustment of the -Tune filter center frequency, you may press the [CLEAR] button to re-center the filter response on your current operating frequency. 4. Press the [SELECT] knob (momentarily) once more to disengage the -Tune filter;
the tuning position of the -Tune filter disappears from the Tuning Offset Indicator on the display. In this mode, only the fixed bandpass filter for the current band will be engaged. Advice: The -Tune Filter selection will be memorized independently on each VFO stack of the VFO-A and VFO-B. Advice:
The -Tune filters are the most advanced, selective RF preselector filters ever incorporated into an Amateur Radio transceiver. The RF selectivity provided by
-Tune can be of tremendous value in ensuring quiet, intermod-free reception even in the most crowded bands on a contest weekend. The -Tune filters provide RF 46 Vertex Standard Co., Ltd. FT-950 Operating Manual 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 -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 as to make it impossible to hear band noise when -Tune is engaged (highly unlikely), just switch it out, which has slightly less insertion loss.
As you tune around on an amateur band with -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(-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 -Tune filter on your operating frequency, and eliminate any offset, press the
[CLEAR] button. Quick Note: The permeability-tuning concept utilized in the -Tune circuit dates back many decades, as it was incorporated in such classic transceivers as the FT-101 and FT-901 series, in addition to the FT DX 400 and similar models. The -Tuning Kit uses a same circuit of our flag ship model FTDX9000 which is the highest development of this circuit concept ever employed in an Amateur transceiver. IPO (Intercept Point Optimization) The IPO feature allows the operator to optimize the characteristics of the receiver front end, depending on the current noise level and the strength of incoming signals. Press the [IPO] button several times to set the desired characteristic of the receiver front end, per the chart below. AMP1: Amplifies the incoming signal path using a low distortion RF preamplifier
(gain: approx. 10 dB). AMP2: Amplifies the incoming signal path using a 2-stage low-distortion RF preamplifier (total gain: approx. 17 dB). Bypasses the RF preamplifier, yielding direct feed to the first mixer. ON:
The selected receiver RF preamplifier will be indicated in the IPO column of the Block Diagram Display on the display. Advice:
The IPO selection will be memorized independently on each VFO stack of the 47 Vertex Standard Co., Ltd. FT-950 Operating Manual 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 ON position 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. AUTO 15 kHz 6 kHz 3 kHz AUTO Advice:
As you repeatedly press the [R.FLT] button, you will observe changes in the notation in the R.FLT column of the Block Diagram Display on the display, denoting the Roofing Filter currently in use.
Typically, this selection will be set to AUTO.
The Roofing Filter selection will be memorized independently on each VFO stack of the VFO-A and VFO-B. 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.
The AUTO mode Roofing Filter selections are shown below:
AM/FM/FM-PKT 15 kHz 6 kHz LSB/USB/PKT CW/RTTY 3 kHz
When the Roofing filter mode is set to AUTO and the Noise Blanker is turned On, the Roofing Filter bandwidth will automatically be set to 15 kHz, as this setting provides the most effective noise blanking. However, you still may override the 48 Vertex Standard Co., Ltd. FT-950 Operating Manual automatic setting, and select a more narrow Roofing Filter. Noise blanking may be compromised, however, with a tighter Roofing Filter in the line. Terminology: A Roofing Filter, as its name implies, places a Roof over the receivers 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. IF Noise Blanker (NB) Operation The FT-950 includes an effective IF Noise Blanker, which can significantly reduce noise caused by automotive ignition systems. 1. Press the [NB] button momentarily to reduce short-duration pulse noise such as from switching transients, automobile ignitions and power lines. The NB icon will appear in the display to confirm that the Narrow-NB is operating. Press and hold in the [NB] button for two seconds to reduce longer-duration man-made pulse noise. The NB icon will blink for five seconds, and thereafter will appear continuously, to confirm that the Wide-NB is operating. 2. Adjust the Noise Blanker level via the Menu item 067 RGEN NB LVL to the point where the offending noise is best reduced or eliminated, if desired. See box below for details. 3. To end Noise Blanker operation, press the [NB] button once more. The NB icon will turn off, confirming that the Noise Blanker is no longer in operation. Advice:
The Noise Blanker operation will be memorized independently on each VFO stack of the VFO-A and VFO-B. However, the Noise Blanker level is in common.
When the Roofing filters mode is set to AUTO and the Noise Blanker is turned ON, the Roofing Filter bandwidth will automatically be set to 15 kHz. The Roofing Filter may be changed to a narrower selection, as described previously, although Noise Blanker operation may be compromised somewhat when using a narrower Roofing Filter. Adjusting the Noise Blanker Level 1. Press the [MENU] button to engage the Menu mode. 2. Rotate the [SELECT] knob to select Menu item 067 RGEN NB LVL. 49 Vertex Standard Co., Ltd. FT-950 Operating Manual Advice: Press the [SELECT] knob to toggle the Menu item display between 067 RGEN and NB LVL. Rotate the [CLAR/VFO-B] knob to the point where the offending noise is best reduced or eliminated. 3. Press and hold in the [MENU] button for two seconds to lock in the new setting and exit to normal operation. CONTOUR Control Operation The Contour filtering system provides a gentle perturbation of the IF filter passband, so as to suppress or enhance certain frequency components, thus enhancing the sound and/or readability of a received signal. 1. Press the [CONT] button. The LED inside the [CONT] button glows orange. The
[SELECT] knob works as Contour knob. 2. Press the [SELECT] knob to activate the Contour filter. The current null (or peak) position of the Contour filter will appear in the CONTOUR indicator on the display. 3. Rotate the [SELECT] knob to achieve the most natural-sounding audio reproduction on the incoming signal. 4. Press the [CLEAR] button to move the null (or peak) position to center. 5. To cancel Contour tuning, press the [SELECT] button once more. The graphic disappears from the CONTOUR indicator on the display, confirming that the Contour filter is no longer operation. Advice:
The Contour filter selection will be memorized independently on each VFO stack of the VFO-A and VFO-B.
The Contour filters level (either nulling or peaking) may be adjusted using Menu item 068 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 069 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 50 Vertex Standard Co., Ltd. FT-950 Operating Manual 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. Reference to Figure (B), this show an indentation of the Contour filter is center of the passband. The Contour filter is placing a low-Q notch (per the setting of Menu item 068, referenced above). Counter-clockwise rotation (to the left) of the [SELECT] knob causes the indentation to move towered a lower frequency within the passband, while clockwise rotation (to the right) causes the indentation to move toward a higher frequency within the passband. By removing interference or unwanted frequency components on 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 can, when adjusted aggressively, impart an unnatural sound to an incoming signal. Oftentimes, though, 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 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 vary the DSP filter passband higher or lower, without changing the pitch of the incoming signal, so as to reduce or eliminate interference. Because the carrier tuning frequency is not varied, there is no need to re-tune the operating frequency when eliminating 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] button glows orange. The
[SELECT] knob works as the IF SHIFT knob. The center position of the IF passband appears in the SHIFT indicator on the display. 2. Rotate the [SHIFT] knob to the left or right to reduce the interference. 3. Press the [CLEAR] button to move the filter passband to center. Advice: The center position of the IF passband will be memorized independently on 51 Vertex Standard Co., Ltd. FT-950 Operating Manual each VFO stack of the VFO-A and VFO-B. Referring to Figure (A), note the depiction of the IF DSP filter as the thick line, with the [SELECT(SHIFT)] knob in the 12 oclock position. In Figure (B), an interfering signal has appeared inside the original passband. In Figure (C), you can see the effect of rotating the [SELECT(SHIFT)] knob so as to reduce the interference level by moving the filter passband so that the interference is outside of the passband. WIDTH (IF DSP Bandwidth) Tuning (SSB/CW/RTTY/PKT Modes) The IF WIDTH tuning system allows you to vary the width of the DSP IF passband, so as to eliminate interference. Moreover, the bandwidth may actually be expanded from its default setting, should you wish to enhance incoming signal fidelity when interference on the band is low. 1. Press the [WIDTH] button. The LED inside the [WIDTH] button glows orange. The [SELECT] knob works as the WITDH knob. The current bandwidth appears in the WIDTH indicator on the display. 2. Rotate the [SELECT] knob to the left or right to reduce the interference. 3. Press the [CLEAR] button to set the bandwidth to default. Advice: The IF Bandwidth will be memorized independently on each VFO stack of the 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 widen the bandwidth. The default bandwidths, and total bandwidth adjustment range, will vary according to the operating mode:
SSB Mode: 1.8 kHz ~ 3.0 kHz (default: 2.4 kHz). CW Mode: 500 Hz ~ 2.4 kHz (default: 2.4 kHz) RTTY/PKT Modes: 500 Hz ~ 2.4 kHz (default: 500 Hz) 52 Vertex Standard Co., Ltd. FT-950 Operating Manual Using IF SHIFT and WIDTH Together 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. Advice: For best interference reduction, the WIDTH and SHIFT features are the primary tools you should use. After narrowing the bandwidth (WIDTH) and/or adjusting the center of the passband (SHIFT), the Contour control may also yield additional signal-enhancement benefits on the net residual bandwidth. Whats more, the IF NOTCH Filter (described later) may also be utilized, in conjunction with the three other filter systems, to significant advantage. NARROW (NAR) One-Touch IF Filter Selection Pressing the [NAR] button provides one-touch, mode-specific selection of a narrow IF DSP filter setting that does not depend on the setting of the [WIDTH] knob. Pressing the [NAR] button once more returns the bandwidth control to the WITDH/SHIFT system. The factory default bandwidths are:
Operating Mode SSB CW RTTY/PKT-L/PKT-U PKT-FM AM FM (28/50 MHz Bands) 500 Hz ~ 2.4 kHz* (2.4 kHz) 500 Hz ~ 2.4 kHz* (500 Hz) 100 ~ 500 Hz* (500 Hz) 100 ~ 500 Hz* (300 Hz) 200 Hz ~ 1.8 kHz* (1.8 kHz) 1.8 ~ 3.0 kHz* (2.4 kHz) 16 kHz 9 kHz 16 kHz 9 kHz 6 kHz 9 kHz
[NAR] Switch OFF ON
*: Depends on the [WIDTH] knob
(): Default Bandwidth Advice:
When the narrow bandwidth is selected, the NAR icon will appear in the display.
Even if the [NAR] button has been pressed so as to engage the narrow filter, you may adjust the IF bandwidth by rotating the [SELECT(WIDTH)] knob (requires 53 Vertex Standard Co., Ltd. FT-950 Operating Manual pressing the [WIDTH] button), and IF SHIFT still is operational (requires pressing the [SHIFT] button). For many applications, you may find that simple pressing the
[NAR] button instead of adjustment of the [WIDTH] knob, may be satisfactory for interference reduction
When you press the [NAR] button in the FM mode, both the transmit and receive bandwidths are narrowed. IF NOTCH Filter Operation (SSB/CW/RTTY/PKT/AM Modes) The IF NOTCH filter is a highly-effective system that allows you to slice out an interfering beat note or other carrier signal from inside the receiver passband. 1. Press the [NOTCH] button. The LED inside the [NOTCH] button glows orange. The [SELECT] knob works as Notch knob. 2. Press the [SELECT] knob to activate the Notch filter. The current null position of the NOTCH filter will appear in the NOTCH indicator on the display. 3. Rotate the [SELECT] knob to adjust the null position of the Notch filter. 4. Press the [CLEAR] button to move the null position to center. 5. To cancel the NOTCH filter, press the [SELECT] button once more. The graphic disappears from the NOTCH indicator on the display, confirming that the NOTCH filter is no longer operation. Advice:
The IF NOTCH Filter selection will be memorized independently on each VFO stack of the VFO-A and VFO-B.
The width of the IF NOTCH null may be adjusted using Menu item 072 RGEN NOTCH W. Both Wide and Narrow selections are available, with Narrow providing the least disruption of the desired signal.
When the optional DMU-2000 Data Management Unit is connected, the effect of the IF NOTCH filter may be observed on the Audio Scope (on the Oscilloscope page). The Notch will be observed as a dip in the noise platform observed. Whats more, the Waterfall display may be used to observe the effect of the IF NOTCH filter, which will appear as a white area in the colored background area. The performance of the IF NOTCH filter is shown in Figure (A), where the effect of rotation of the [SELECT(NOTCH)] knobs is depicted. In Figure (B) you can see the notching effect of the IF NOTCH filter as you rotate the [SELECT(NOTCH)] knobs to 54 Vertex Standard Co., Ltd. FT-950 Operating Manual eliminate the incoming interference. Digital NOTCH Filter (DNF) Operation The Digital NOTCH Filter (DNF) is an effective beat-cancelling 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 effective notching tool in the receiver section. 1. Press the [MENU] button to enter the Menu mode. 2. Rotate the [SELECT] knob to select Menu item 070 RGEN DNF. Advice: Press the [SELECT] knob to toggle the Menu item display between 070 RGEN and DNF. 3. Rotate the [CLAR/VFO-B] knob to select ON. The DNF icon will appear in the display. 4. Press and hold in the [MENU] button for two seconds to save the new setting and exit to normal operation. To disable the Digital NOTCH Filter, just repeat the above procedure, rotating the
[CLAR/VFO-B] knob to select OFF in step 3 above. The DNF icon will turn off, confirming that the Digital NOTCH Filter is not active. Advice: The Digital NOTCH Filter selection will be memorized independently on each VFO stack of the VFO-A and VFO-B. 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 071 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 experienced. 1. Press the [MENU] button to enter the Menu mode. 2. Rotate the [SELECT] knob to select Menu item 071 RGEN DNR. Advice: Press the [SELECT] knob to toggle the Menu item display between 071 RGEN and DNR. 55 Vertex Standard Co., Ltd. FT-950 Operating Manual 3. Rotate the [CLAR/VFO-B] knob to select the setting that most effectively reduces the noise level. The DNR icon will appear in the display. 4. Press and hold in the [MENU] button for two seconds to save the new setting and exit to normal operation. To disable the DNR system, just repeat the above procedure, rotating the
[CLAR/VFO-B] knob to select OFF in step 3 above. The DNR icon will turn off, confirming that the DNR system is not active. Advice: The Digital Noise Reduction will be memorized independently on each VFO stack of the VFO-A and VFO-B. RF Gain (SSB/CW/AM Modes) The RF Gain controls provide manual adjustment of the gain levels for the receiver RF and IF stages, to account for noise and/or 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, as well, the S-meter will appear to be pegged against the right edge of the analog S-meter scale. Quick Point:
Reception frequently can be optimized by rotating the [RF GAIN] knob slightly counter-clockwise to the point where the incoming noise level is just about the same as the stationary meter needle position as set by the adjustment of the [RF GAIN] knob. 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 Attenuator features, all affect the 56 Vertex Standard Co., Ltd. FT-950 Operating Manual system receiver gain in different ways. As a first step in dealing with high noise 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 so as to optimize performance fully. Audio Pitch Control (SSB mode) The FT-950 enables to adjust the receiver audio response by shifting the carrier point during the SSB operation. 1. Press the [MENU] button to enter the Menu mode. 2. Rotate the [SELECT] knob to select Menu item 065 A3J LSB CAR or 066 A3J USB CAR. Advice: Press the [SELECT] knob to toggle the Menu item display between Menu Item Number & Group Name and Menu Function. 3. Rotate the [CLAR/VFO-B] knob to adjust the desired receiver audio response. 4. Press and hold in the [MENU] button for two seconds to save the new setting and exit to normal operation. AGC (Automatic Gain Control) The AGC system is designed to help compensate for fading and other propagation effects, with characteristics that can be of particular value on 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 operation, we recommend the AUTO mode. Additionally, you may disable the AGC by pressing and holding in the [AGC] button for two seconds. 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, for example). The AUTO mode selections are:
Operation Mode AUTO AGC Selection 57 Vertex Standard Co., Ltd. LSB/USB CW AM FM RTTY PKT(FM) PKT(LSB) FT-950 Operating Manual SLOW FAST FAST FAST SLOW FAST SLOW Advice:
The AGC selection will be memorized independently on each VFO stack of the VFO-A and VFO-B.
If the AGC receiver-recovery time is set to the Off by pressing and holding in the
[AGC] button, the S-meter will no longer deflect. Additionally, you will likely encounter distortion on stronger signals, as the IF amplifiers and the following stages are probably being overloaded. Quick point: Several aspects of AGC performance may be configured via the Menu. However, because AGC can have such a profound impact on overall receiver performance, we generally do not recommend any changes to the AGC Menu selections until you are thoroughly familiar with the performance of the FT-950. Terminology: Automatic Gain Control, or AGC, is a circuit that senses the incoming signal strength, and then limits the gains of the RF and IF stages so as 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. Mute Feature There may be occasions, when you want to silence the receiving audio of the FT-950 temporarily, such as to concentrate on whats being received on the other receiver or telephone call. The Mute feature makes this simple to accomplish. Press the [(VFO-A)RX] Indicator/Switch while receiving the VFO-A frequency or Memory channel. The FT-950 will be silenced and the green LED in the [(VFO-A)RX]
Indicator/Switch will blink. To restore reception, just press the blinking [(VFO-A)RX] Indicator/Switch once more. While receiving the VFO-B frequency, press the [(VFO-B)RX] Indicator/Switch. The 58 Vertex Standard Co., Ltd. FT-950 Operating Manual FT-950 will be silenced and the green LED in the [(VFO-B)RX] Indicator/Switch will blink. To restore reception, just press the blinking [(VFO-B)RX] Indicator/Switch once more. Advice: If you press the [POWER] switch momentarily while the transceiver is turned on, the transceivers audio will be muted for three seconds. SSB/AM Mode Transmission 1. Press the [BAND] button corresponding to the Amateur band on which you wish to operation. 2. Press the [SSB] button for SSB operation. For AM operation press the [AM/FM]
button repeatedly until the AM icon appears in the display. Advice: By convention, LSB is used in the 7 MHz and lower Amateur bands for SSB communication, and USB is used on the 14 MHz and higher bands (the 10 MHz band is used for CW and data modes only). 3. Rotate the Main Tuning Dial knob to adjust the operating frequency. Alternatively, you may use the [UP]/[DWN] scanning buttons on the MH-31B8 Hand Microphone to sweep up or down the current band. 4. Press the microphones PTT (Push To Talk) switch to begin transmission; speak into the microphone in a normal voice level. Advice:
The TX indicator will light up in the frequency display area, confirming that transmission is in progress.
When transmitting in the AM mode, set a maximum (carrier) power output of 25 Watts via the Menu item 112 TGEN AM CAR. See below Box for details of the setting. 5. Adjust the microphone amplifier gain to match the microphone and your voice level: press the [METER] switch repeatedly to select the ALC meter, close the PTT switch, and speak into the microphone in a normal voice level. In the SSB mode, adjust the [MIC GAIN] knob so that the ALC meter stays within the ALC zone of the meter (up to half scale deflection) on voice peaks. In the AM mode, adjust the [MIC GAIN] knob so that the ALC meter does not deflect at the voice peak. 6. Release the PTT switch at the end of your transmission. The transceiver will return to the receive mode. 59 Vertex Standard Co., Ltd. FT-950 Operating Manual 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 an impedance very close to 50 Ohms.
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, and you should always use the minimum power necessary for maintaining reliable communications.
When performing tests (such as the setup of the [MIC GAIN] knob), be sure to check the frequency before transmitting, so as 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, and you may choose the technique(s) that best suit your operating needs:
Pressing the microphones 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 ??. Adjusting the AM Carrier 1. Press the [MENU] button to enter the Menu mode. 2. Rotate the [SELECT] knob to select Menu item 112 TGEN AM CAR. Advice: Press the [SELECT] knob to toggle the Menu item display between 112 TGEN and AM CAR. 3. Close the PTT switch without the microphone input. rotate the [CLAR/VFO-B]
knob to adjust the PO meter reading is 25 W. 4. Press and hold in the [MENU] button for two seconds to save the new setting and exit to normal operation. 60 Vertex Standard Co., Ltd. FT-950 Operating Manual Using the Automatic Antenna Tuner The Automatic Antenna Tuner (hereinafter referred to as the ATU) built into each FT-950 is crafted to ensure a 50-Ohm load for the final amplifier stage of the transmitter. We recommend that the ATU be used whenever you operate on the FT-950. Advice:
The ATU of the FT-950, being located inside the station, 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 feedpoint itself. When designing and building your antenna system, we recommend that every effort be made to ensure a low SWR at the antenna feedpoint.
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 HF amateur bands (6 m band: 25 Ohms to 100 Ohms, corresponding to an SWR of 2:1 or less). 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 TUNER 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 two seconds to begin automatic tuning. The transmitter will be engaged, and the TUNER icon will blink while tuning is in progress. When the optimum tuning point has been reached, the radio will return to receive, and the TUNER icon will again glow steadily (instead of 61 Vertex Standard Co., Ltd. blinking). FT-950 Operating Manual 4. While tuning around the band using the Main Tuning Dial knob, you will observe that the TUNER icon blinks momentarily every 10 kHz. This momentary blinking indicates that a new tuning window has been entered. If you want to save tuning data associated with this 10 kHz window, repeat step 4 (above) for each such window. On bands like 1.8 MHz where the impedance may change rapidly, the storage of a number of tuning points is recommended. 5. To disconnect the ATU from the transmit line, press the [TUNE] button momentarily. The TUNER 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. 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.
The momentary flickering of the TUNER icon occurs whenever you cross over into a new 10 kHz ATU memory window. 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 already have completed the tuning process. About ATU Operation Figure 1 depicts a situation where normal tuning via the ATU has been successfully completed, and the tuning data has been stored in the ATU memory. The antenna system as seen by the transmitter is shown. 62 Vertex Standard Co., Ltd. FT-950 Operating Manual In Figure 2, the operator has changed frequency, and the HI SWR 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 conditions exists (above 3:1), corrective action must be taken in the antenna system to bring the impedance closer to 50 Ohms. Besides the fact that the ATU will refuse to memorize settings on frequencies where the SWR exceeds 3:1, the high SWR may indicate a mechanical failure in the feed system, and such failures can lead to the generation of spurious signals causing TVI, etc. About ATU Memories SWR (Post-tuning) Less than 1.5:1 The tuning settings are committed to the ATU memory. SWR (Post-tuning) Greater than 1.5:1 Tuning data will not be retained in memory. If you return to the same frequency, the tuning process must be repeated. SWR (Post-tuning) Greater than 3:1 The HI SWR LED will light up, and tuning settings, if achieved, will not be memorized. Please investigate and resolve the high SWR condition before attempting further operation using this antenna. 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 during SSB transmission. However, the bandwidth may be varied by the operator, so as to provide different levels of fidelity or talk power, according to your preferences. Heres how to adjust the transmitted bandwidth on SSB:
1. Press the [MENU] button to engage the Menu. 2. Rotate the [SELECT] knob so as to select Menu item 064 A3J TX BPF. Advice: Press the [SELECT] knob to toggle the Menu item display between 064 A3J and TX BPF. 3. Rotate the [CLAR/VFO-B] knob to select the desired bandwidth. The available selections are 1-30 (100-3000 Hz), 1-29 (100-2900 Hz), 2-28 (200-2800 Hz), 3-27 63 Vertex Standard Co., Ltd. FT-950 Operating Manual
(300-2700 Hz), 4-26 (400-2600 Hz) , 3000WB and the default is 3-27 (300-2700 Hz). A wider bandwidth will provide greater fidelity, while 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 two seconds to save the new setting and exit to normal operation. Advice:
The Transmit Monitor is very helpful way of verifying the effects on fidelity of changing the bandwidth. Pressing the [MONI] button 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. Quick Points:
The higher fidelity associated with wide bandwidth will be particularly enjoyable on the low bands, during local rag-chew QSOs.
The 3000WB setting is a special hi-fidelity setting, whereby the transmitted bandwidth is in excess of 3 kHz. This selection, in conjunction with judicious adjustment of the Parametric Microphone Equalizer (see next chapter) can provide truly outstanding fidelity and very natural-sounding audio.
When using the wider bandwidth selections (especially 3000WB), the apparent power output from the transmitter may seem lower. This is because the available power from the transmitter is being distributed over a wider bandwidth, and the power detection circuitry does not compensate for the effect of the bandwidth selection (it is calibrated in the default 2.4 kHz bandwidth). 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. 64 Vertex Standard Co., Ltd. FT-950 Operating Manual Quick Point: The Parametric Equalizer is a unique technique for adjusting the signal quality. Because the three ranges may be adjusted so precisely, it is possible to craft a response that provides a more natural and pleasant sound than you have ever experienced before. Effective talk power can also 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 Gain:
Q:
adjusted. The amount of enhancement (or suppression) within each band may be adjusted. 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 as not to cause interference to other users during adjustment. Advice:
We recommend you consider connecting a dummy load to one of the Antenna jacks, and monitor your signal on a separate receiver, so as 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 monitoring your transmitted signal. 3. To adjust the Parametric Microphone Equalizer while the speech processor is disabled, press the [PROC] button until the MIC EQ icon appears in the display. To adjust the Parametric Microphone Equalizer with the speech processor engaged, press the [PROC] button until the MIC EQ and PROC icons appear in the display. 4. Press the [MONI] button, if you want to listen on the FT-950s internal monitor. 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 100; 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. 65 Vertex Standard Co., Ltd. FT-950 Operating Manual 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 effects of the changes you are making. Because the overall effect on the sound will change with each adjustment you make, you should make several passes through each adjustment area, to be sure that you are achieving the optimum setting. 9. When you have completed all adjustments, press and hold in the [MENU] button for two seconds to save the new settings and exit to normal operation. If you only press the [MENU] button momentarily to exit, any changes you performed will not 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 users voice will be different, often requiring different settings. Activating the Parametric Microphone Equalizer 1. Adjust the [MIC GAIN] knob for SSB use, as described on page ??. 2. Press the [PROC] button momentarily. The MIC EQ icon will appear in the display, confirming that the Parametric Microphone Equalizer is engaged. Advice A blinking MIC ICON icon indicates the Parametric Microphone Equalizer menu settings have all been set to OFF (091 TAUD EQ1 FRQ, 094 TAUD EQ2 FRQ, 097 TAUD EQ3 FRQ. 3. Press the PTT switch on the microphone, and speak into the microphone in a normal voice level. 4.

Press the [METER] button repeatedly to select COMP (Compression) meter. 3. Press the [PROC] button repeatedly until the MIC EQ and PROC icons will appear in the display, confirming that the Speech Processor is engaged. 4. Press the [PTT] switch on the microphone, and speak into the microphone in a normal voice level. Observe the deflection of the meter needle on the COMP meter scale. 67 Vertex Standard Co., Ltd. FT-950 Operating Manual 5. Adjust the compression level of the Speech Processor via the Menu Item 109 TGEN PROCLVL so that the meter needle deflects to not more than 10 dB on the COMP meter scale. See Box at the right for details of the setting. 6. To switch the Speech Processor off, press the [PROC] button once more. The MIC EQ and PROC icons will turn off, confirming that the Speech processor is turned off. Advice:
Excessive advancement of the compression gain will result in a degradation of the transmitted signals signal-to-noise ratio, thereby reducing intelligibility at the other end of the circuit.
The Transmit Monitor is very helpful way of verifying proper adjustment of the compression level. Pressing the [MONI] button 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 adjustments.
You may set the RF power output via the Menu item 111 TGEN TX PWR, whether or not the Speech Processor is engaged.
You may adjust the Parametric Microphone Equalizer when the speech processor is engaged, using Menu Items 100 through 108. See page ?? for details.

72 Vertex Standard Co., Ltd. FT-950 Operating Manual
If you are using the speaker for monitoring, instead of headphones, excessive advancement of the [MONI] knob can cause feedback to occur. Additionally, this feedback can cause the VOX system to hang up in a loop, making it impossible to return to receive. Therefore, we recommend the use of headphones, if at all possible, or the minimum usable setting of the [MONI] knob, if the speaker must be used.
Because the Monitor feature utilizes a sampling of the transmitters IF signal, it can be very useful for checking the adjustment of the Speech Processor or Parametric Equalizer on SSB, and for checking the general signal quality on AM and FM. Split Operation Using the TX Clarifier (VFO-A Operation) 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 9.99 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:
To listen to the pile-up calling the DX station, so as to find the station currently being worked, you may press the [RX CLAR] button. Once you have zeroed 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 stations 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 not lost, and will be available if you turn the TX Clarifier back on. To clear the Clarifier offset, press the [CLEAR] button. 73 Vertex Standard Co., Ltd. FT-950 Operating Manual 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. Clarifier Offset Bar Indicator A visual depiction of the relative offset of the Clarifier may be displayed, using the Bar Indicator. 1. Press the [MENU] button to engage the Menu mode. 2. Rotate the [SELECT] knob to select Menu item 006 DISP BAR SEL. Advice: Press the [SELECT] knob to toggle the Menu item display between 006 DISP and BAR SEL. 3.

When you are finished, press and hold in the [MENU] button for two seconds to save the new setting and exit to normal operation. CW Convenience Features CW Spotting (Zero-Beating) Spotting (zeroing in on another CW station) is a handy technique for ensuring that 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 panels [SPOT] button, the Spot tone will be heard and the frequency display will show the Spot tone frequency. This tone corresponds to the pitch 80 Vertex Standard Co., Ltd. FT-950 Operating Manual of your transmitted signal, and if you adjust the receiver frequency to match the pitch of the received CW signal to that of the Spot tone, your transmitted signal will be precisely matched to that of the other station. Release the [SPOT] button to turn the Spot tone off. Advice:
In a tough DX pile-up, you may actually want to use the SPOT system to find a gap in the spread of calling stations, instead of zeroing in precisely on the last station being worked by the DX station. From the DX side, if a dozen or more operators (also using Yaesus 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 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. Quick Points:
The CW Spotting process utilizes the Spot tone or the Tuning Offset Indicator. The actual offset pitches being set by the Menu item 045 A1A PITCH (see page ??). The offset pitch may be set to any frequency between 300 Hz and 1050 Hz, in 50 Hz steps, and you can either match tones audibly (using the [SPOT] button) or align 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 its default OFSt setting. 81 Vertex Standard Co., Ltd. FT-950 Operating Manual 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 throw the interfering stations frequency in a direction that may lend itself more readily to rejection. 1. To start, lets 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 the VFO-A, and press the [CW]
mode button once more. The CW and LSB icons will appear in the display, indicating that the LSB injection side has now been selected. 3. Press the [CW] mode button once more to return to the normal (USB) injection side and cancel CW Reverse operation (the CW and USB icons will appear in the display). In the illustration, Figure A demonstrates the normal CW injection setup, using the USB side. In Figure B, CW Reverse has been engaged, so as to receive using LSB-side injection to eliminate interference. The beneficial effect of switching sidebands can clearly be seen in this example. Notes:
When CW Reverse is engaged, the Tuning Offset Indicator action will concurrently be reversed as to its indication.
When the incoming signal pitch tone is properly aligned, the central red marker lights up whether or not CW Reverse is engaged. CW Delay Time Setting During semi-break-in (not QSK) operation, the hang time of the transmitter, after you have finished sending, may be adjusted to a comfortable value consistent with your sending speed. This is the functional equivalent to the VOX Delay adjustment used on voice modes, and the delay may be varied anywhere between 30 msec and 3 seconds via the Menu item 044 A1A DELAY. 1. Press the [BK-IN] button to enable CW transmission (Menu item 043 A1A BK-IN must be set to SEni). 2. Press the [MENU] button to enter the Menu mode. 82 Vertex Standard Co., Ltd. FT-950 Operating Manual 3. Rotate the [SELECT] knob to select Menu item 044 A1A DELAY. Advice: Press the [SELECT] knob to toggle the Menu item display between 044 A1A and DELAY. 4. Start sending, rotate the [CLAR/VFO-B] knob so that the hang time is as you prefer for comfortable operation. 5. When you are finished, press and hold in the [MENU] button for two seconds to save the new setting and exit to normal operation. CW Pitch Adjustment You may allow adjustment of the center frequency of the receiver passband, as well as the pitch of your offset CW carrier, to the tone you prefer via the Menu item 045 A1A PITCH. The tone may be varied between 300 Hz and 1050 Hz, in 50 Hz steps. 1. Press the [MENU] button to enter the Menu mode. 2. Rotate the [SELECT] knob to select Menu item 045 A1A PITCH. Advice: Press the [SELECT] knob to toggle the Menu item display between 045 A1A and PITCH. 3. Rotate the [CLAR/VFO-B] knob to select the desired tone. 4. When you are finished, press and hold in the [MENU] button for two seconds to save the new setting and exit to normal operation. Advice: You may confirm the Spot tone frequency when pressing the [SPOT] button. The frequency display will shows the Spot tone frequency. 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), so as 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. Contest Memory Keyer The FT-950 in capable of the automatic sending of CW messages (as you might do in a contest). Two techniques for message storage are available: you may either send the desired message contents using your keyer paddle (Message Memory), or you may input the text characters using the Main Dial Tuning knob and [CLAR/VFO-B] knobs

FT-950 Operating Manual recommend that 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.
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 transmitters 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. 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. Quick Point: When you have configured Menu item 114 TGEN VOX SEL to dAtA, the transceiver will operate in a VOX mode, and it is not necessary to connect a PTT line.

Very high Q is made possible by the narrow-band design. Three RF Tuning Kit 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 RF stage is especially helpful in 132 Vertex Standard Co., Ltd. FT-950 Operating Manual preventing IMD and blocking. Installation Assemble the RF Tuning Unit according to the RF Tuning Kit Installation Manual supplied from the RF Tuning Kit. Interconnections to FT-950 Connect each cable (supplied from the RF Tuning Kit) between the RF Tuning Unit and the FT-950 Transceiver. Advice:
The RF connecting cables are color coded (black and gray) to assist in properly connecting the RF IN and RF OUT jacks. (see illustration)
Miss-connection will not damage the RF Tuning Kit. However, improper operation may occur.
Connect the color-coded control cable(s) between the CNTL OUT and CNTL IN jacks (see illustration). Confirm all connections before turning on the transceiver.
If the FT-950 does not operate and the frequency display blinks sometimes, confirm and correct the CNTL IN and CNTL OUT connections on the RF Tuning Unit.
The order of connecting multiple RF Tuning Unit is not important. Operation Please see page ?? on this Operating Manual. 133 Vertex Standard Co., Ltd. General Rx Frequency Range:
