There is an ELECRAFT Application Note Front Panel Microphone Circuit
Modification.

You have it on your K3?

|I have a situation with the CMP and ACL graphs indicating and a scratchy
|noise that happens many times when I press the PTT button pn my MH2  mic.
|If I tap it or speak into it the graphs return to normal and  the noise
|disappears  I grounded pin 2 on the mic  jack on the K3 and  there is no noise or
|graph indication.  I connected  my Kenwood  mic and it happens with it
|also. Could there be some RF feedback  getting into the mic circuit ?
