HALDIMAN OPERATIONS II.A. ORBITER FREQUENCIES DATE: PAGE DIRECTORATE AUGUST 26, 1987 8 ORBITER COMMUNICATION FREQUENCIES ARE MUCH HIGHER THAN RADIO STATION FREQUENCIES, AS INDICATED BELOW. THREE FREQUENCY RANGES ARE USED BY THE ORBITER: UHF, S-BAND, AND KU-BAND. THE FIVE ORBITER RF SYSTEMS ARE NAMED BY THEIR FREQUENCY RANGES: UHF SYSTEM, S-BAND PM SYSTEM, S-BAND FM SYSTEM, S-BAND P/L SYSTEM, AND KU-BAND SYSTEM. ORBITER FREQUENCIES* In WWII , we had VS "Secret codes" for RADIO STATION FREQUENCIES* radio freq. KU 85 RADIO STATIONS Bod mix are from those 80 - 120 MHz codes. UHF (AIR-TO-AIR) S-BD PM, FM, & P/L KU BAND 240 - 300 MHz 1,750 - 2,300 MHz 13,000 - 15,000 MHz 80 120 ...
