Compiled by The P/\NTHER I would like to introduce you to a new form of communications called Aeronautical Telephone Calls (ATC) which are basically cellular phones adapted for use in commercial airlines. The customer must either enter his/her calling card manualy or via magnettic stripe to place local or international calls. The following is information in regards to this subject and I think you will find it quite interesting.. Enjoy. __________________________________________________________________________ PART I - GENERAL INFO AERONAUTICAL TELEPHONE CALLS AIR-GROUND RADIOPHONE - These frequencies are used to provide Air to Ground RadioPhone service to Aircraft in Flight. AERONAUTICAL FREQUENCY ASSIGNMENTS CHANNEL GROUND PLANE -------------------------------------- 1 454.950 459.950 2 454.900 459.900 3 454.850 459.850 4 454.800 459.800 5 454.750 459.750 6 454.700 459.700 7 454.725 459.725 8 454.825 459.825 9 454.925 459.925 10 454.875 459.875 11 454.925 459.925 12 454.975 454.975 CALLING 454.675 459.675 AIRFONE MOBILE TELEPHONE CHANNELS The AIRFONE Company has recently been authorized to use the 849 to 851 MHZ and 944 to 946 MHZ reserved Land Mobile Frequencies for Commercial Air-To-Ground telephone service on a developmental basis over the next two years. It is expected that the Federal Communications Commission will establish this as a permanent service later this year. GROUND STATIONS AIRCRAFT ________________________ ________________________ 849.0000 TO 851.0000 MHZ 894.0000 TO 896.0000 MHZ 944.0000 TO 946.0000 MHZ 899.0000 TO 901.0000 MHZ The mode of Trnsmission is SSB and a receiver must be capable of this mode of reception. Channel spacing is .006 MHZ and the specific channel ranges will be listed under each ground station location. __________________________________________________________________________ PART II - COMMUNITY LISTINGS In the UHF (454 to 459 Mhz) Air-Ground Radiophone the ground station on 454.XXXX is noted followed by the Aircraft frequency 459.XXXX. The new experimental Air-Ground Radiophone (849-851 and 944-946 Mhz) Listings show the range of frequencies for both the ground station and the aircraft. These frequencies are assigned on a .006 Mhz spacing and each location is assigned a block of 32 frequencies . Due to the limited range of the ground stations it is suggested that the aircraft frequencies (894-896) and (899-901) be monitored. NATIONWIDE ---------- SERVICE LICENSEE CODE/CALLSIGN FREQ1.

The Voice channels are currently Analog here in LA but for how long? Hurry B4 they Go Digital! Are there control channels? Which scanner can receive SSB transmissions? Will DTMF signals come through when the magnettic strip is used or will it be encoded? If you need ATC frequencies for any of the 50 U.S. States please contact UMF for a list.
