Interesting. Mine has never gone off near an airport with a rapcon, etc., but I'll bet it depends on how close you come to a given antenna / emitter. I'll actually bet it's the doppler transmitter, but who knows? And I can't figure out the one near ATL at all. Whatever. Thanks ... good information.
