                           orbit operations.

       Note from Ron Parise, WA4SIR, on above S-band frequencies:
 "The S-band system is one of the primary orbiter downlink bands.
 The voice channels are digital slope delta modulation and are
 MUX'ed in with the rest of orbiter telemetry very difficult to
 copy.  Much of the downlink TV is S-band wide band FM and should
 be easy to copy.

       The Ku-band system is used in conjunction with the TDRS
 satellites, and is used more heavily during Spacelab flight than
 others.  The data rate is very high digital (50 Mbits/sec), and
 will be nearly impossible for you to demodulate and decommutate
 in your basement. Nevertheless, the shuttle transmits on 15.003
 GHz.  These transmission are directed toward the TDRS satellite
 with a high gain antenna, and cannot be copied from the ground.

       The UHF frequencies are fun to listen to, but are not
 heavily used except during EVA's.  You will almost always hear
 some activity on them during a mission, just be patient."
