Neat!!! I've wondered what that would be like to take an FM RX up on a plane with you. Back in 1988, as a birthday gift, I got a 30min local plane ride over the famed ex-P.O. drop of P.O.Box 452-land. However, instead of an FM radio, I took along one of those Citizen pocket-sized LCD B&W TV. That, and my Dad bummed me his camera to take PIC's of areas of interest. Anyway, most hilltops there are about 2,400ft ASL, and I believe that we, (Myself and the pilot.), were about 3,000ft above ground. The pilot wouldn't allow me to extend the TV's antenna, so with a retracted 3" antenna, here's what it received. All of the county PBS UHF TV translators for WNED-TV, Buffalo. That's UHF. On VHF-high, only thing RX'ed was Buffalo's CH7 WKBW-TV CATV quality. Nothing else, like CH11 CHCH-TV, or any of the Rochester, NY stations. On VHF-low, nothing, not even a hint of Buffalo's CH's 2 and 4. Still, a neat experiment. Makes me only wonder what I would have RX'ed if I was allowed to extend the telescopic whip, or even stick it out the window.
