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.
