SpaceNews originates at KD2BD in Wall Township, New Jersey, USA.  It
is published every week and is made available for non-commercial use.

TO-31 was offically opened for general amateur use this past weekend.
This move allows amateur radio operators to use the store and forward
communications transponder on the spacecraft, and also download the high
resolution multispectral earth images taken by the satellite.

It is hoped that amateur radio operators will take advantage of downloading
the high resolution multispectral images available from TO-31 and keep other
traffic to a minimum.  Due to current limitations with on-board memory,
images will only be available on the satellite for a couple of days after
they are taken.  If other files (especially large files) are uploaded to
the satellite, this will ultimately increase the amount of time taken to
download images and they may therefore be deleted before they are completed.

Unfortunately, the transmitter is still causing some problems and the
downlink is not currently operating over most areas.  Amateurs in Europe
and South-East Asia will find the downlink on most of the time, and it will
remain on for between 15 and 30 minutes, depending on the operation of
the transmitter.  This will allow amateurs in areas close to the command
stations to access the satellite, but others will probably find the
transmitter off at most times.  In the coming weeks, it is hoped that
the transmitter will be able to be switched on over more areas to allow
many more amateurs to access TO-31.

During some of these tests, access may again be limited to command stations
only.  If at any time the BBS is "SHUT" (as displayed in WiSP etc) please do
not attempt to access the satellite as it may delay any commanding that is
being undertaken.

On 1983-Nov-28, astronaut Owen Garriott, W5LFL, was launched into
space on STS-9.  He brought along the first amateur radio station on a
crew-tended space vehicle.  Thousands heard Owen's downlink and hundreds
had a direct QSO with him.

Since that time 15 years ago, the internationally-based human spaceflight
amateur radio community has done some pretty tremendous things for amateur
radio and for education.  Frank Bauer, KA3HDO, of the SAREX Working Group,
wishes to thank and congratulate the hundreds of volunteers around the world
who have taken the dream that was shared by Owen, the ARRL, AMSAT-NA and NASA,
and turned it into a reality that has benefited the world-wide community of
radio amateurs as well as students in classrooms.  Through the efforts of
the individuals belonging to these organizations, we have amateur radio
stations that have flown on all Space Shuttles and on Mir, and we are
currently on the threshold of installing a permanent amateur radio station
on the International Space Station (ISS).  

On behalf of the SAREX Working Group and as a US Delegate to the Amateur
Radio on the International Space Station (ARISS) program, Frank Bauer looks
forward to the continued cooperation of all the international partners that
comprise ARISS as we jointly forge a new, exciting future for amateur radio
in space.

KITSAT-OSCAR-25 has returned to normal operation.  Alan, WA4SCA, reports
that KITSAT-OSCAR-23 seems to be back to normal after recently experiencing
some downlink problems, but reports downlink transmitter is now about 6 kHz
higher in frequency.

Hank Riley, N1LTV, has written a compact windows-based program called
"Sputnik telemetry Assistant" that interprets audio frequencies measured
from the transmissions made by Sputnik-41, and uses this information to
calculate the temperature on-board the tiny satellite.  The program does
this by interpolating between previously published frequencies and their
corresponding temperatures.  Results provided are rounded to the nearest
tenth of a degree in both Celsius and Fahrenheit.
The program is only 8 kilobytes in size (unzipped) and runs under Windows
3.x and higher.  The program was developed independent of the Sputnik 41
project management.  It has been carefully checked for accuracy, but is
not guarenteed to be bug-proof.

Hank's program may be retrieved from his HABLIC Web site:

front page.  Comments may be addressed to Hank at: h1riley@umassd.edu

AMSAT-LU is in its last phase for the launch of VOXSAT 1, its next satellite
for radio amateur worldwide service.  VOXSAT 1 will be placed inside a Russian
satellite (as AO-21 was), for launch next year.

The satellite will carry the following modes:

1 Cross Band FM repeater, (like AO-27), UHF up / VHF down.
2 Parrot UHF up / VHF down.
3 Broadcast Voice, FAX, SSTV, (like Sputnik 41).
4 CW Telemetry (using an FM carrier).

The VHF output power for the downlink repeater TX is two watts, and four
for the broadcast TX.

Further information on VOXSAT 1 may be found at the following URL:
