FM Rx clicking and other sound problems

I noticed such clicks in the FMN modulation not only at the end of transmission but also during Rx, even when the volume is turned to zero. After switching to FM the problem disappears.

FMN is a abbreviation for 12.5kHz bandwidth, if the radio experiences over deviation there is likley to be clipping on the audio
