The space shuttle press kit is at http://www.osf.hq.nasa.gov/shuttle/(sts#)/, substituting the mission number where (sts#) is shown (e.g., http://www.osf.hq.nasa.gov/shuttle/sts69/).
For up-to-date and detailed information call the following:
The Space Shuttle transmits on three frequency bands: UHF, S-Band, and Ku-Band.
The UHF frequencies are simple AM voice and are very easy to copy. These
frequencies are used for launch and landing operations, EVA operations, and as
an additional voice downlink when other channels are in use for the current
ground station has no S-Band capability.
The frequencies in use are:
The S-Band system is one of the primary Orbiter downlink bands. The voice channels are digital slope delta modulated and are multiplexed in with the rest of the Orbiter telemetry and is very difficult to copy. Much of the downlink TV is on S-Band also, but is wideband FM and should be easy to copy. The frequencies are:
The Ku-Band system is used in conjunction with the tracking and data relay satellites and is used much more heavily in Spacelab flights than in others. The data rate is very high (50 Mbit/s). These transmissions are directed to TDRS satellites in geostationary orbit on a frequency of 15.003 GHz.
Shuttle Audio Retransmissions
You can also telnet "spacelink.msfc.nasa.gov" and follow the menus to a listing
of repeaters in the USA that offer this service. Retransmissions of Shuttle audio on amateur radio frequencies
