STS-47 SAREX Update

This is a SAREX update for STS-47 on September 13, 1992 at 18:00 UTC.

With approximately 24 hours of on-orbit operations, the Shuttle Amateur Radio 
Experiment (SAREX) is performing flawlessly, providing excitement and an 
educational experience to school groups and radio amateurs worldwide.  Just a 
few hours after launch, Mission Specialist, Jay Apt, N5QWL, checked out the 
SAREX station, which includes 2-meter voice and packet.  After the station was 
checked out, the Heathkit HK-21 TNC was configured for packet robot operations 
while the crew continued their activation, checkout, and initial operations of 
the Spacelab-J hardware.  In the scant few hours since the station was 
activated, over 632 packet contacts have been made.  In addition, three school 
groups, two in Australia and one in the U.S., have made superb horizon to 
horizon contacts with the crew.  These include the Australian Maritime College, 
which asked 7 questions, the Wesley College, in South Perth, where 9 questions 
were asked, and the Del-Mar Middle School in Santa Cruz, California.  At Del-
Mar middle School, 7 students asked 7 questions with over 150 students in 
attendance.  Two more Australian and three more U.S. school groups have yet to 
have their turn on the mike.  

As a reminder, the SAREX station on-board the Space Shuttle Endeavour has two 
radio amateurs on board.  This includes Dr. Jay Apt, N5QWL, and Dr. Mamoru 
Mohri, 7L2NJY.  The packet radio callsign is W5RRR-1.  The 2-meter FM voice and 
packet downlinks are on 145.55 MHz.

Uplinks are:		Voice		Packet

Europe			144.80		144.70
			144.75
			144.70

Rest of World		144.95		144.70
			144.97
			144.91

The following represents the latest Keplerian Element Set for Gil Carmen, 
WA5NOM.  The predictions from this set are within a few seconds of the actual 
orbit.  Spacelab-J is a life science and microgravity mission.  During 
microgravity missions, thruster firings are significantly curtailed.  Thus, an 
element set for STS-47 should be quite valid for several days.
