Re: IC-F121 Power on beep
U can also turn the volume down. The control is behind the microphone jack, just unplug the mic and look in the jack it is mounted on the board at the back of the jack.

Re: Icom F121 Receiver Sensitivity Problems
the problem is the 2nd BPF, the 450khz filter. They are a bit of a pain to change as the entire ckt board has to be removed because the filter is mounted on the bottom of the board.
