Just to make sure I understand the problem: when you change frequency, in RX is there any audio heard and is it only static? In TX there is audio, but only static, heard by the receiving station?
Does this happen on all bands (HF/VHF/UHF)? All modes (CW/USB/FM)? How often does this happen (always, usually, occasionally)? Is it worse on one band than others?
Does the frequency seem stable and accurate when listening to one frequency, with no slow or rapid drifting? Do you notice a change between when the radio is cold compared to warm?
When you transmit, what does the ALC indicator show (and in what mode)?
To test just the audio DSP circuit on the Logic board, try making a voice recording (page 96 in my user manual), then listening to it. Does the audio sound OK?
Any other details, such as what you were doing when the problem first appeared, etc. might help.
