Any intercom within a radio with only one microphone
circuit (rather than one per headset) is not a proper
intercom. Any paralleling of mikes will cause problems if
you parallel a DC set (low impedance) with almost anything
else (high impedance).
And as Carl says a lack of squelch also makes it not much
use as an intercom.
So always use a separate intercom.
Richard Holder who hasn't done any fibreglassing but
certainly knows about radios, headsets. electrics and ANR :-)
