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
