Hey Buly (and anyone else)
I’ve got an RST intercom
and an ICOM radio (don’t
remember the number but only 1 year old). When the engine is off I can
hear and Xmit fine. Turn the engine on and I can still hear fine (i.e.
no
noise) but when I key the mic there is a ton of noise in my headset and
in the
broadcast. It’s not high pitched just a mid-range noise.
I ruled out the
alternator by taking the belt off –
noise was still there.
So why noise only when I
transmit? Any thoughts?
