Well since I am new here my post need to moderator approved. While waiting for my previous post about using the Tecsun PL 660, PL680 or PL880 for aircraft I pulled the trigger for about $65 new and shipped from an Amazon vendor. What sold me was the adjustable squelch and I think it can scan the airband as well. Not 100% sure on that but even so it's good anyway as the other don't scan either. I did have to give up SSB but for my budget and my location near MEM International airport with airband being my priority I think I made a solid choice. I will post my experience after it arrives.
