phone amplifier gain to match the
microphone and your voice level.
set the [
METER
] switch to the
“ALC” position and close the
PTT
switch. Speak into the microphone in
a normal voice level, and adjust the


The microphone gain of
the AM mode has been programmed at the factory
to a level that should be satisfactory for most situ-
ations. However, using Menu item “
051 A3E MIC
GAIN ”, you may set a different fixed value, or
choose the “MCVR” option, which then lets you
use the front panel [
MIC
] knob to set the micro-
phone 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 used on SSB will be satisfactory.

The relative Microphone Gain level will show for
3 seconds in the lower right corner of the Main
Display whenever the inner [
MIC ] knob is turned.
Alternately, the 3-second display feature may be
changed to show in the
SUB DISPLAY- III

dow via Menu item “ 018 DISP INDI ”. Addition-
ally, you may disable the 3-second display feature
via Menu item “
017 DISP LVL IND ” See page
