1. The operating mode is selected using the [ MODE ]
switches to the left of the [ Main
Tuning Dial ] knob, and the VFO
(A or B) to which the selection is
applied is selected by pressing the
[ A ] or [ B ] switch above the Mode
keys. Press the [ A ] or [ B ] key to
select the desired VFO, then press
the [ LSB ] or [ USB ] key to select
one of the SSB modes. For AM
operation, press the [ AM ] key.

UICK OINT
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).
2. Rotate the [ Main Tuning Dial ] knob to adjust the
operating frequency. Alternatively, if using the optional
MD-200 Desktop Microphone, you may use the
A8X
Up/Down scanning buttons to sweep up or down the
current band.

Be sure to verify that the microphone you are using is
enabled for operation via the Menu. There are two mi-
crophone jacks (the front panel's three-pin XLR ("Can-
non") connector, and the rear panel's 8-pin round con-
nector), and either jack may be chosen independently
for SSB, AM, and FM operation. See the Menu list
below for details of the associated Menu Item:

3. Press the microphone's PTT (Push To Talk) switch to
begin transmission; speak into the microphone in a
normal voice level.

DVICE
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 ] control so as to set a maximum (carrier)
power output of 50 Watts.
Release the PTT switch at the end of your trans-
mission. The transceiver will return to the receive
mode.
4. To adjust the microphone amplifier gain to match the
microphone and your voice
level, close the PTT switch,
speak into the microphone in
a normal voice level, and ad-
just the [ MIC ] (gain) control
as follows:
SSB Mode
Adjust the [ MIC ] control so that the ALC voltage (dis-
played on the right meter) stays within the ALC zone
of the meter (up to 2/3 or full scale deflection) on voice
peaks.
For AM, the [ MIC ] control 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.
Please adjust the [ MIC ] gain control
to set the ALC within this range.
