if using the optional MD-200A8X Desktop Microphone, you may use the Up/Down
scanning buttons to sweep up or down the current band.
2. Press the microphone’s 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, rotate the [RF PWR] knob so as to set a
maximum (carrier) power output of 25 Watts.
1. In the SSB mode, adjust the microphone amplifier gain to match the microphone
and your voice level, set the [METER] switch to the “ALC” position, close the PTT
switch, speak into the microphone in a normal voice level, and adjust the [MIC]
(gain) knob so that the ALC voltage (displayed on the right meter) stays within the
ALC zone of the meter (up to 2/3 or full scale deflection) on voice peaks.
Advice:
The microphone gain of the AM mode has been programmed that should be
satisfactory for most situations at the factory. However, using Menu item “049 A3E
MICGAIN,” you may set a different fixed value, or choose the “Ur” option, which
then lets you use the front panel [MIC] knob to set the microphone gain in the AM
mode. In this case, the [MIC] knob should not be advanced to the point where the
ALC meter deflects. In many cases, the same setting as used on SSB will be
satisfactory.
2. Release the PTT switch at the end of your transmission. The transceiver will
return to the receive mode.
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 [MIC] knob adjustments into a dummy load or antenna system
presenting an impedance very close to 50 Ohms.
Rotate the [RF PWR] knob to set the desired power output. Clockwise rotation of
the [RF PWR] knob will increase the power. The adjustment range is between 5
Watts and 100 Watts, and you should always use the minimum power necessary for
maintaining reliable communications.
