450 MHz Air-Ground Mobile Phones
Below are the frequencies for the 400MHz air-to-ground telephones found in private Aircraft.
The transmissions on these frequencies are FM. Cities throughout the country have been
allocated anywhere from one to three of the channels listed below. Those channel allocations
are listed below. Keep in mind that not all the allocated channels may be in use in a
particular area.
When monitoring these frequencies, be aware that the ground stations repeat the airborne half
of the converstion, but transmit an annoying continuous tone when not in use. If you are within
range of the ground station and want to avoid the tones but hear both sides of calls when
they're made, you can do so by programming both frequencies into your scanner. Lock out the
ground frequencies when scanning, and when a call is received from a plane, manually step up
to the ground frequency to hear both sides. If you are out of range of the ground station,
you will only be able to hear the plane side of the conversation. This service is used on
private aircraft.
