1. Selecting the Operating Mode
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 ap-
plied 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 opera-
tion, press the [ AM ] key.

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 op-
tional MD-200 Desktop Microphone, you may use
A8X
the 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
microphone jacks (the front panel's three-pin XLR
("Cannon") connector, and the rear panel's 8-pin
round connector), and either jack may be chosen in-
dependently for SSB, AM, and FM operation.

3. Press the microphone's PTT (Push To Talk) switch to
begin transmission; speak into the microphone in a
normal voice level.
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
adjust 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 satis-
factory.
Please adjust the MIC gain con-
trol to set the ALC within this range.
