Hey Jim. How about an antenna-line pad (maybe 40 dB or so) that you
could switch in when listening to unicom? The local guys would still
break squelch, but the guys 100 miles away wouldn't. And even with
step-ons, I suspect the hetrodyne squeal would be reduced. Make it
selectable by a pushbutton on the intercom. For safety, maybe it
could automatically switch itself out when you changed frequency or
radios. (How? I dunno. Maybe sense a change in the L.O. freq?)

You can also just tighten the squelch. The heterodynes will still be
there though, even if you rigged up a pad.
