A good trick for sure. I often work a group with a station a mile away on 40 
meters. I back the rf gain down a bit, and shorten the a g c delay just enough 
so the receiver doesn't take quite as long to recover. That way, can hear the 
weak sigs.

On c w, a good trick is to disable the rf gain altogetherif that feature is 
available.
