strange microphonic feedback at loud RX volume

Post by 26mb04 »

Has anyone else had this problem? I was at work last night with one of my newly-fixed handhelds (Icom F4062) and there was an annoying feedback sound at high volume RX. Turning the volume down cleared the noise, but then I couldn't hear anything above the ambient noise. It's annoying, the sort of problem I'd expect on TX if anything (with sidetone etc), but not RX.
