You'll want a fairly good skirt on the receiver.  I'm not sure a BC 
348 would work.

I use my R4C's.

I generally watch the S meter without listening, although I do 
sometimes monitor on the other receiver for a few seconds. I 
always wear headphones anyway, so I can hear my TX audio on 
the monitor in my main rig.
