I have a muff on the mike , if it was any closer I'd have to swallow it !
There are slits on both sides of the mike .
When using the radio the transmissions are noisy but undestandable , the
intercom is another story ,I can squelch out the noise but when speaking the
squelch opens and all you hear is engine noise ( not electrical
interference)with a voice in it . What I need to do is filter out the
background noise somehow. Any suggestions? Peter.
