The FT-950 is a leading-edge transceiver with a number of new and exciting features, some of which may be unfamiliar to you. [. . . ] Press the [ PROC ] button repeatedly until the " " and " " icons appear in the display, confirming that the Speech Processor is engaged. ADVICE: Blinking " " and " " icons indicate the Parametric Microphone Equalizer menu settings have all been set to "OFF ("100 TAUD PE1 FRQ "103 OFF" FRQ", 103 OFF 100 FRQ", 106 FRQ"). Press the PTT switch on the microphone, and speak into the microphone in a normal voice level. Observe the level indicated on the COMP meter scale. Adjust the compression level of the Speech Processor via the Menu Item "109 TGEN PROCLVL so that the PROCLVL" 109 meter needle does not indicate more than "10 dB" on the COMP meter scale. See Box at the right for details of the setting. [PROC] Button [MIC GAIN] Knob [METER] Button 6. To switch the Speech Processor off, press the [PROC] button once more. The " " and " " 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 signal's signal-to-noise ratio, thereby reducing intelligibility at the other end of the circuit. The Transmit Monitor is a very helpful way to verify proper adjustment of the compression level. Pressing the [MONI] button and then adjusting the [MONI] knob for a comfortable listening level while you are transmitting, you will be able to hear the difference in sound quality as you make adjustments. You may set the RF power output via the Menu item "111 TGEN TX PWR whether or not the Speech ProPWR", 111 cessor is engaged. You may adjust the Parametric Microphone Equalizer when the speech processor is engaged, using Menu Items "100 through "108 See page 117 for de100" 108". When the optional DMU-2000 Data Management Unit is connected, you may observe the effect of your compression level adjustments by viewing the waveform on the "Oscilloscope" page. Adjusting the compression level of the Speech Processor 1. Press the [METER] button repeatedly to select "COMP" (Compression) meter. Press the [MENU] button to engage the Menu. Rotate the [SELECT] knob to select Menu item "109 TGEN PROCLVL PROCLVL". 109 ADVICE: Press the [SELECT] knob to toggle the Menu item display between "109 TGEN and "PROCLVL PROCLVL". Press the PTT switch on the microphone, and speak into the microphone in a normal voice level. Rotate the [CLAR/VFO-B] knob so that the meter deflects to not more than "10 dB" on the COMP meter scale. Press and hold in the [MENU] button for one second to save the new setting and exit to normal operation. [SELECT] Knob [METER] Button [MENU] Button [CLAR/VFO-B] Knob Page 62 FT-950 OPERATING MANUAL 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. [. . . ] Similarly, locate the Coaxial plug (labeled ) installed in jack (J1029) on the MAIN Unit. Unplug the Coaxial plug ( ) from the MAIN Unit and plug it into the J7003 on the SCOPE Unit. Referring to Figure 4, lay out the Coaxial cables into the slits of the chassis. Replace the bottom case and its 18 screws.
