8819Re: Aircraft band
- Nov 13, 2013When transmitting from an FM radio to an AM radio, try shifting your
transmit frequency up or down from 5K to 10K Hz. This will better fool
the detector in the distant AM receiver. I have done this and it works
well for short ranges, but not so well for long distances like 5-60 miles.
As you probably know, 121.5 is still monitored by FAA ground stations,
but no longer by the satellites (last I heard). So the 121.5 frequency
might not be dependable if you need to use it from a down airplane.
