My understanding is that even if you have a type-accepted radio for airband, you may only use a ground-based station to communicate with aircraft in DIRECT SUPPORT of aviation activities. The control tower obviously qualifies, and so do providers of aviation services such as fixed-base operators... but I don't know whether the experiments you want to run would qualify. It's been my experience from bumming around with some of my friends who are into kitplanes that the airband is pretty strictly monitored, and I'd hate for you to run into any problems. Of course, you may very well know more about the restrictions in your area than I do. Just my $0.02.
<br><br>Why not just run a 2m or 70cm rig from the plane? It's perfectly acceptable to do that as long as the aircraft is operating VFR and you have the approval of the pilot-in-command.<br><br>Josh<br><br><div><span class="gmail_quote">

Hummh... We all have these radios that tune the<br>118-137 MHz AM aircraft band... But what channels<br>are available to communicate plane to plane or<br>plane to ground?<br><br>Our aerospace department has a plane they fly
<br>occasionally for flight studies. What channel<br>can I talk to them on to coordinate some GPS<br>experiements for example? (That isnt too<br>crowded)<br><br>Here is the list I got on the web, I'm hoping<br>someone private pilots out there have made
