450 MHz Air-Ground Mobile Phones Below are the freuqncies 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 alllocations are listed below. Keep in mind that all channels may not 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.

The transmissions on these frequencies are AM, with the channels spaced 6 kHz apart. The ten blocks of 29 have been assigned to various areas of the country, and cities having the same block are separated by at least 300 miles. The allocations are listed below. The ground frequencies do not echo the airborne half of the conversation.
