Anyone looking for a good handheld radio should check out the JHP nav/com at http://www.acespilotshop.com/pilot-supplies/handheld/jhp-520.htm or other suppliers. With a good aircraft antenna I have picked up radio transmissions from as distant as 180 miles and on a recent trip I communicated with our local tower from 85 miles out. A.S. sells an adaptor to easily plug in to aircraft power. Great price for a good radio. Use an adaptor to plug headset into radio or I plugged a two place intercom into the radio and headsets in to the intercom. I didn't have room for a panel mount so mine is mounted below panel between my knees. https://dl.dropboxusercontent.com/u/32133949/IMG_8619.JPG Good location.
