Wanted Air Phone Freq's

Post by BigJimsP » Mon, 28 Nov 1994 15:20:18

Just in case it is not legal, will someone tell me where not to tune my
scanner, and what type of modulation method I should avoid.

I have used the old seat back Airphone on many of airplane, but always
wondered if my conversation was being easily intercepted by fellow scanner
listeners.

I would appreciate any info.


Thanks

    of the converstion, and transmit a continuous tone when idle. From
    one to three channels are assigned in a particular area.
        Service is used on private aircraft.

[D
using the 800 mhz version. VERY easy to intercept the air to ground
side, at least here in the heartland. Just search 894>896 MHz
in 5 KHz steps in the AM mode and there they are! Dozens at peak
times, less at others. Cost is a consideration of course!
