Interestingly enough, the public references long ago published the shuttle comm frequencies. Summarizing from:
http://spaceflight.nasa.gov/shuttle/reference/shutref/orbiter/comm/orbcomm/ S-band PM forward link frequencies: 2,106.4 MHz (primary) or 2,041.9 MHz (secondary) S-band PM reverse link frequencies: 2,287.5 MHz (primary) or 2,217.5 MHz (secondary) S-band PM forward link frequencies, military missions: 1,831.8 MHz (primary) or 1,775.5 MHz (secondary) S-band PM reverse link frequencies: 2,287.5 MHz (primary) or 2,217.5 MHz (secondary) - same as civilian S-band FM downlink: 2,250.0 MHz Ku-band forward link: 13.755 GHz Ku-band reverse link: 15.003 GHz UHF AM frequencies: 296.8 MHz, 259.7 MHz, 243.0 MHz (emergencies only) and 279.0 MHz (EVA only) Now it's certainly possible that this is misinformation, except for the UHF frequencies 296.8 and 259.7, which many hams (including myself) have personally verified. --Phil --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
