Even
if the

of
your
antenna
system
is about
3:1,
the
built-in tuner matches the antenna system to 50 Q.
MONITOR

(p. 33)
Monitors your transmit signals.
Use this switch with
the [MONITOR GAIN] control.

Use this switch
with the [MIC GAIN] control.
TRANSMIT/RECEIVE
SWITCH
Manually switches from receiving to transmitting or
vice versa.

(p. 5)
Measures

Do you have a question about the IC -765 and is the answer not in the manual?
Questions and answers
how to adjust the transmit bandwidth
To adjust the transmit bandwidth on the Icom IC-765, you can select between LSB and USB modes depending on the frequency band:
- USB is automatically selected on bands above 10 MHz.
- LSB is automatically selected on bands below 7 MHz.
- Push the [SSB] button again to switch between USB and LSB.
The SSB selectivity (bandwidth) is fixed at 2.2 kHz at –6 dB. There is no direct control to manually change the transmit bandwidth beyond selecting USB or LSB.
