1. The operating mode is selected using the [ MODE ]
buttons to the left of the Main Tuning Dial knob, and
the VFO (A or B) to which the selection is applied is
selected by the [ A ] or [ B ] button above the [ MODE ]
buttons. Usually, the [ A ] button glows Red, signifying
that the Main band (VFO-A) is be-
ing adjusted. Similarly, pressing the
[ B ] button will cause its indicator to
blink Orange for five seconds, sig-
nifying Sub band (VFO-B) adjust-
ment. Therefore, press the [ A ] or [ B ]
button to select the desired VFO,
then press the [ LSB ] or [ USB ] but-
ton to select one of the SSB modes.
For AM operation, press the [ AM/
FM ] button repeatedly until the im-
bedded LED glows red.

By convention, LSB is used in the 7 MHz and lower
Amateur bands for SSB communication, and USB
is used on the 14 MHz and higher bands (the 10
MHz band is used for CW and data modes only).
When the [ AM/FM ] button glows orange, it indi-
cates that FM operation is engaged.
2. Rotate the Main Tuning Dial knob to adjust the oper-
ating frequency. Alternatively, you may use the [ UP ] /
[ DWN ] scanning buttons on the MH-31
crophone to sweep up or down the current band.

The "
" 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.
4. 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 of full scale
deflection) on voice peaks.

The microphone
gain of the AM
mode has been pro-
grammed, at the
factory, to a level
that should be satisfactory for most situations. How-
ever, using Menu item "050 A3E MICGAIN
set a different fixed value, or choose the "Ur
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.
5. Release the PTT switch at the end of your transmis-
sion. The transceiver will return to the receive mode.
