I am looking for some guidance with my prc 351. I have a loud pop or crackling sound on the audio both transmit and recieve thru the full range of the radio. This problem deveolped after I have used the radio for several months without any trouble. The noise is not present on the sidetone as heard in the handset. I have checked the audio connections, substituted handsets, check for corrosion around the audio connections, changed batteries and antennas. Would anyone have any other suggustions. do you know if there is a particular module that may be at fault.
thanks in advance for any help,
