INSTALLATION AND INTERCONNECTIONS ANTENNA CONSIDERATIONS The FT-950 is designed for use with any antenna system providing a 50 Ohm resistive impedance at the desired operating frequency. While minor excursions from the 50-Ohm specification are of no consequence, if the Standing Wave Ratio (SWR) present at the Antenna jack is greater than 3:1, the transceiver’s Automatic Antenna Tuner may not be able to reduce the impedance mismatch to an acceptable value.
INSTALLATION AND INTERCONNECTIONS GROUNDING The FT-950 transceiver, like any other HF communications apparatus, requires an effective ground system for maximum electrical safety and best communications effectiveness. A good ground system can contribute to station efficiency in a number of ways: It can minimize the possibility of electrical shock to the operator.
INSTALLATION AND INTERCONNECTIONS CONNECTION OF ANTENNA AND POWER CABLES Please follow the outline in the illustration regarding the proper connection of antenna coaxial cables, as well as the DC power cable. The DC power connector for the FT-950 must only be connected to a DC source providing 13.8 Volts DC (±10 %), and capable of at least 22 Amperes of current. Always observe proper polarity when making DC connection: The RED DC power lead connects to the Positive (+) DC terminal.

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.
BASIC OPERATION:RECEIVING ON AMATEUR BANDS LOCK You may lock the setting of the Main Tuning Dial knob (for VFO-A frequency tuning) and the [CLAR/VFO-B] knob (for VFO-B frequency tuning), to prevent accidental frequency change. To lock the Main Tuning Dial knob and the [CLAR/VFO-B] knob, 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, press the [ LOCK ] button once more.
CONVENIENCE FEATURES USING THE VFO-B VFO-B operates similar to VFO-A, which you should be familiar with by now. However, the [CLAR/VFO-B] knob, instead of the Main Tuning Dial knob selects the frequency for VFO-B (See box below for tuning rate). The two VFOs make simple transmit/receive split frequency operation possible. Use various combinations of the four VFO red and green transmit and receive switches to set up split frequency operation. The [SPLIT] button also sets up split frequency operation.
CONVENIENCE FEATURES “MY BANDS” OPERATION When operating on an Amateur Band, it is possible to use the [BAND] button to engage the [CLAR/VFO-B] knob for Amateur band selection. The “My Bands” feature allows you to skip some Amateur bands, and make only your preferred 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 bands are not used, or if you do not have antennas for some bands. “My Bands” Setup 1.
CONVENIENCE FEATURES BAND STACK OPERATION The FT-950 utilizes a triple band-stack VFO selection technique, that permits you to store up to three favorite frequencies and modes onto each band’s VFO register. For example, you may store one frequency each on 14 MHz CW, RTTY, and USB, then recall these VFOs by successive, momentary presses of the [14] MHz band button. Each Amateur band key may similarly have up to three frequency/mode settings applied.

Now, beginning with the first digit of the frequency (the leftmost digit), we will enter the required digits of the frequency. 2.
INTERFERENCE REJECTION RECEIVER OPERATION (FRONT END BLOCK DIAGRAM) The FT-950 includes a wide range of special features to suppress the many types of interference that may be encountered on the HF bands. However, real world interference conditions are constantly changing, so optimum setting of the controls is somewhat of an art, requiring familiarity with the types of interference and the subtle effects of some of the controls.
INTERFERENCE REJECTION ATT When extremely strong local signals or high noise, still degrades reception, you can use the [ATT] button to insert 6, 12, or 18-dB of RF attenuation in front of the RF amplifier. 1. Press the [ATT] button several times to set the desired attenuation level, per the chart below.
INTERFERENCE REJECTION μ-TUNE FILTER (REQUIRES THE OPTIONAL RF μTUNING KIT) The RF μTuning Kit provides ultra-sharp RF selectivity for the front end of the transceiver. Very high Q is made possible by the narrow-band design. Three RF μTuning Kits are available. The MTU-160 covers the 1.8 MHz band. The MTU-80/ 40 covers the 3.5 and 7 MHz bands. The MTU-30/20 covers 10.1 and 14 MHz bands.
INTERFERENCE REJECTION μ-TUNE FILTER (REQUIRES THE OPTIONAL RF μTUNING KIT) ADVICE: The μ-Tune filters are the most advanced, selective RF preselector filters ever incorporated into an Amateur Radio transceiver. The RF selectivity provided by μ-Tune can be of tremendous value in ensuring quiet, intermod-free reception even in the most crowded bands on a contest weekend.
INTERFERENCE REJECTION 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, according to the chart below. [IPO] Button Block Diagram Display : Amplifies the incoming signals, using a low distortion RF preamplifier (gain: approx. 10 dB).
INTERFERENCE REJECTION 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.).
INTERFERENCE REJECTION 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 “ ” icon will appear in the display to confirm that the NarrowNB is operating. Press and hold in the [NB] button for two seconds to reduce longer-duration man-made pulse noise.
INTERFERENCE REJECTION CONTOUR CONTROL OPERATION The Contour filtering system provides a gentle perturbation of the IF filter passband. The Contour is set to either suppress, or boost specific frequency components, and thus enhance the sound and readability of a received signal. 1. Press the [CONT] button to activate the Contour filter. The LED inside the [CONT] button glows orange and the current “null” (or “peak”) position of the Contour filter will appear in the CONTOUR indicator on the display.
INTERFERENCE REJECTION IF SHIFT OPERATION (SSB/CW/RTTY/PKT/AM MODES) IF SHIFT allows you to move the DSP filter passband higher or lower, without changing the pitch of the incoming signal, and thus reduce or eliminate interference. Because the carrier tuning frequency is not varied, there is no need to re-tune the operating frequency to eliminate the interference. The total passband tuning range for the IF SHIFT system is ±1 kHz. 1. Press the [SHIFT] button. The LED inside the [SHIFT] button glows orange.
INTERFERENCE REJECTION 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, to reduce or 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 functions as the WITDH knob.
INTERFERENCE REJECTION 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 [SELECT(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) [NAR] SWITCH “ON” “OFF” 200 Hz ~ 1.8 kHzÚ 1.8 ~ 3.0 kHzÚ (1.8 kHz) (2.
INTERFERENCE REJECTION 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 to activate the Notch filter. The LED inside the [NOTCH] button glows orange and the current “null” position of the NOTCH filter will appear in the NOTCH indicator on the display. The [SELECT] knob functions as the Notch adjustment knob. 2.
INTERFERENCE REJECTION DIGITAL NOTCH FILTER (DNF) OPERATION The Digital NOTCH Filter (DNF) is an effective beat-canceling filter that can null out a number of interfering beat notes inside the receiver passband. Because this is an Auto-Notch feature, there is no adjustment knob associated with this filter. ADVICE: If a very strong interfering carrier is encountered, we recommend you first use the IF NOTCH filter, as it is the most effective notching tool in the receiver section. 1.
INTERFERENCE REJECTION 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 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.
TOOLS FOR COMFORTABLE AND EFFECTIVE RECEPTION AUDIO PITCH CONTROL (SSB MODE) The FT-950 permits adjustment of the receiver audio response by shifting the carrier point during SSB operation. 1. Press the [MENU] button to enter the Menu mode. 065 2. Rotate the [SELECT] knob to select Menu item “065 A3J LSB CAR 066 A3J USB CAR CAR” or “066 CAR”. ADVICE: Press the [SELECT] knob momentarily to toggle the Menu item display between “Menu Item Number & Group Name” and “Menu Function”. 3.
TOOLS FOR COMFORTABLE AND EFFECTIVE RECEPTION AGC (AUTOMATIC GAIN CONTROL) The AGC system is designed to help compensate for fading and other propagation effects. The AGC characteristics can be individually set for each operating mode. The basic objective of AGC is to maintain a constant audio output level once a certain minimum threshold of signal strength is achieved. Press the [AGC] button repeatedly to select the desired receiver-recovery time constant.
SSB/AM MODE TRANSMISSION [POWER] Switch [METER] Switch [VFO-A(RX)] Button [MIC GAIN] Knob 1. Press the [BAND] button corresponding to the Amateur band on which you wish to operate. 2. Press the [SSB] button for SSB operation. For AM operation press the [AM/FM ] button repeatedly until the “ ” icon appears in the display.
SSB/AM MODE TRANSMISSION ADVICE: ALC meter deflection may be caused by excessive drive power, but also by reflected power detected in the antenna system. If the impedance presented to the transceiver is different from 50 Ohms, ALC meter action may be observed that is not related to the proper setting of the [MIC GAIN] knob. Therefore, we recommend that you make the [MIC GAIN] knob adjustments into a dummy load or antenna system presenting impedance very close to 50 Ohms.
USING THE AUTOMATIC ANTENNA TUNER The Automatic Antenna Tuner (hereinafter referred to as the “ATU”) built into each FT-950 is designed to ensure a 50Ohm load for the final amplifier stage of the transmitter. We recommend that the ATU be used whenever you operate on the FT-950. ADVICE: Because the ATU of the FT-950 is located inside the station, it only adjusts the impedance presented to the transceiver at the station end of your coaxial cable feedline.
USING THE AUTOMATIC ANTENNA TUNER ABOUT ATU OPERATION Figure 1 depicts a situation where normal tuning via the ATU has been successfully completed, and the tuning data has been stored in the ATU memory. The antenna system as seen by the transmitter is shown. In Figure 2, the operator has changed frequency, and the “ ” icon has appeared. The operator presses and holds in the [TUNE] button for two seconds to begin impedance matching using the ATU.
ENHANCING TRANSMIT SIGNAL QUALITY PARAMETRIC MICROPHONE EQUALIZER (SSB/AM/FM MODE) The FT-950 includes a unique Three-Band Parametric Microphone Equalizer that provides precise, independent control over the low, mid and treble ranges in your voice waveform. You may utilize one group of settings when the speech processor is off and an alternate group of settings when the speech processor is on. The speech processor feature is described in the next chapter.

Press the [PROC] button momentarily. The “ ” icon will appear in the display, confirming that the Parametric Microphone Equalizer is engaged.
ENHANCING TRANSMIT SIGNAL QUALITY USING THE SPEECH PROCESSOR (SSB AND AM MODES) The FT-950’s Speech Processor is designed to increase “talk power” by increasing the average power output, (via a 100 TAUD PE1 FRQ 103 sophisticated compression technique) and adjusting the audio quality to the menu settings (“100 FRQ”, “103 TAUD PE2 FRQ 106 TAUD PE3 FRQ FRQ”, “106 FRQ”. The result is improved intelligibility when conditions are difficult. 1. Adjust the [MIC GAIN] knob, as described on page 56. 2.
ENHANCING TRANSMIT SIGNAL QUALITY ADJUSTING THE SSB TRANSMITTED BANDWIDTH (SSB MODE) For transmission on SSB, a default bandwidth of 2.4 kHz is provided. This bandwidth provides reasonable fidelity along with good talk power, and is typical of the bandwidth used for decades for SSB transmission. The bandwidth may be varied by the operator, to provide different levels of fidelity or talk power, according to your preferences. Here are the steps to adjust the SSB transmit bandwidth: 1.

CW CONVENIENCE FEATURES CW SPOTTING (ZERO-BEATING) “Spotting” (zeroing in on another CW station) is a handy technique to ensure you and the other station are precisely on the same frequency. The Tuning Offset Indicator in the display may also be moved so you can adjust your receiver frequency to center the incoming station on the pitch corresponding to that of your transmitted signal.
CW CONVENIENCE FEATURES USING CW REVERSE If you experience a difficult interference situation, where an interfering station cannot readily be eliminated, you may wish to try receiving using the opposite sideband. This may move the interfering station’s frequency in a direction that may lend itself more readily to rejection. 1. To start, let’s use a typical example where you have set the CW mode (using the default “USB” injection). 2.
CW CONVENIENCE FEATURES 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 Menu item 044 A1A DELAY “044 DELAY”. 1.
