* SAREX NEWS *
==============
The latest in a series of Shuttle Amateur Radio EXperiments (SAREX)
can be described as being a success.  Although some hardware problems
prevented the reception of SSTV and packet radio by the crew of
Atlantis, many new milestones were created on this mission.

Amateur fast-scan television was successfully received from ground
stations by the SAREX equipment on board Atlantis.  STS-37 marks
the first mission where fast-scan television was ever received on
a manned spacecraft.  The only other time video images were received
in space occurred during the second SAREX mission, carried on STS-51-F
in August 1985, when amateur slow-scan television (SSTV) was received
on the space shuttle Challenger.

SSTV transmissions made by the SAREX equipment carried on STS-37
were successfully received by many ground stations within the
footprint of Atlantis.  These images, transmitted on 145.550 MHz,
showed many details of the extra vehicular activity made by the crew
of STS-37.

STS-37 also marks the first time in history when a shuttle crew
consisted entirely of licensed amateur radio operators.  The performance
and utility of amateur radio on STS-37, as well as on previous STS
missions, help to ensure an opportunity for a permanent and continuing
amateur radio presence in space, including the planned space station
"Freedom".


* NOAA-D NEWS *
===============
NOAA-D is scheduled for launch on 14-May-91 at approximately 15:52 UTC.
This weather satellite will become known as NOAA-12 after launch and will
replace NOAA-10 as the operational morning descending weather spacecraft.

* OSCAR-11 NEWS *
=================
A recent status report of OSCAR-11's on-board computer (OBC) follows:

* RS-12 NEWS *
==============
This past week, long-time OSCAR satellite enthusiast Pat Gowen (G3IOR)
reported he made a rather remarkable QSO with a ZL station from his QTH in
Norwich, England.  The QSO, made over a long-haul DX path, was accomplished
using the Mode K and T transponders flying aboard RS-12.  Pat mentioned that
he had always hoped someday to make a satellite contact with a ZL station
using AO-10 or AO-13 but they were never quite visible to both regions
simultaneously.  With the advent of continuous Modes K and T operations on
RS-12, this may start to become a very popular bird to work DX!  Also, with
the simplest of equipment requirements, it could become very popular with
novice satellite users.

The following table is a summary of the RS-12 Mode KT frequencies:

Uplink   :  21.210 -  21.250 MHz
Downlink :  29.410 -  29.450 MHz
Downlink : 145.910 - 145.950 MHz

Beacons  :  29.4081 MHz (or  29.4543 MHz)
           145.9125 MHz (or 145.9587 MHz)
