- ARLS008 STS-55 update
-
- STS-55 Space Shuttle Columbia is scheduled for launch on Monday,
- March 22 at 14:51 UTC. This will be a 9 day mission. Crew members
- include Steve Nagel, N5RAW, Jerry Ross, N5SCW, Charlie Precourt,
- KB5YSQ, Hans Schlegel, DG1KIH and Ulrich Walter, DG1KIM. SAREX
- operations take place on 2-meter voice and packet. Primary voice
- callsign will be N5RAW. Packet radio callsign is W5RRR-1.
-
- The 2-meter FM voice and packet downlinks for the SAREX station are
- on 145.55 MHz. See Page 42 February 1993 QST for details.
-
- Uplinks are: Voice Packet

- Europe 144.80 144.49
- 144.75
- 144.70

- Rest of World 144.99 144.49
- 144.97
- 144.95
- 144.93
- 144.91
-
- Note: The crew will not favor any specific voice uplink frequency.
- Your ability to communicate with SAREX will be the luck of the draw.
- Earth stations should listen to the downlink frequency and transmit
- only when the Shuttle is in range. Listen for any instructions from
- the astronauts as to uplink frequencies in use during the current
- pass. Also, listen to the uplink frequencies before transmitting to
- avoid interference to other users.
-
- Schlegel and Walter will make contacts with European schools using
- an additional ham radio station designated SAFEX (Spacelab
- Amateurfunk Experiment) in the German spacelab module. We can
- compare the performance of the US SAREX window mounted internal
- antenna to the SAFEX antenna mounted externally on the spacelab
- module in the payload bay. An official Antenna Test is planned for
- orbits 61 and 62. The crew will transmit on 145.55 MHz using the
- SAREX antenna on Orbit 61 and the SAFEX antenna on Orbit 62. Hams
- in Southeastern USA can take signal strength readings of the
- received signal for both passes. To figure times for the orbits,
- add 3 days 18 hours 3 minutes to launch time for Orbit 61 and 3 days
- 19 hours 37 minutes for Orbit 62. Listen to W1AW after the launch
- for exact time of liftoff.
