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?
