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 signal’s 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.
When the optional DMU-2000 Data Management Unit is connected, you may
observe the effect of your compression level adjustments by viewing the wave-form
on the “Oscilloscope” page.
