SAREX TEAM RECEIVES NASA AWARD

HR AMSAT NEWS SERVICE BULLETIN 229.01 FROM AMSAT HQ
SILVER SPRING, MD, AUGUST 17, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-229.01


On Tuesday August 12, the Shuttle Amateur Radio EXperiment (SAREX) team
received a NASA Johnson Space Center Group Acheivement Award.  This award
was given to the SAREX volunteers to recognize the superb efforts put forth
on the STS-94 mission.  The award was given during the STS-94 mission
debriefing session.  SAREX Principal Investigator Matt Bordelon, KC5BTL,
accepted the award for the SAREX team.  The citation on the award reads,
"For your outstanding support during STS-94 that allowed us to contact 17
schools around the world and make multiple contacts with Mike Foale aboard
the Space Station Mir."  AMSAT Vice President for Manned Space Programs
Frank Bauer, KA3HDO, said this to his team of AMSAT volunteers when he
informed them of their prestigous achievement: "The STS-94 crew was duly
impressed with the preparedness of the SAREX schools, the tremendous bridge
contacts, the great contacts with Mike Foale and the smoothness of the
STS-94 SAREX flight operations.  I want to thank you all for your
tremendous support on this and all the activities that you do for SAREX,
Mir and ARISS.  You consistently make me proud".  

AMSAT extends its congratulations to the entire SAREX team for their
efforts which led to the reception of this NASA award.
 
ANS thanks Frank H. Bauer, KA3HDO for this good news.

SB SAT @ AMSAT  $ANS-229.02
TWO NEW WISP FILES UPLOADED

HR AMSAT NEWS SERVICE BULLETIN 229.02 FROM AMSAT HQ
SILVER SPRING, MD, AUGUST 17, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-229.02

Roy Welch W0SD, Manager of AMSAT's Software Exchange announces that
Chris Jackson G7UPN / ZL2TPO has asked him to upload UPDKEPS 2.00C and
PROCMAIL 2.00E.  Roy says that these two
updates fix the problem of the Keplerian elements not being
automatically updated.  As far as he knows, this is the only fix
contained in these two files.  He notes that they should both be
installed at the same time.   The files are named PM200D.ZIP and
UPDK200C.ZIP.  They will be uploaded to satellite KO-23 and have been
put on the AMSAT ftp site at:

ftp://ftp.amsat.org/amsat/software/win32/wisp

W0SL says that these files are updates to WiSP32 for Windows 95.  He
cautions everyone to, as always, retain the old versions until comfortable
that the new versions are working OK. 

ANS Thanks Roy Welch W0SL for this information.

AO-27
(Uplink 145.85 MHz FM, Downlink:
436.792 MHz FM (As of April 1, 1997)
Operating normally.  (See ANS Bulletin 215.05.)
This information can be found at www.umbra.com
AO-27 TEPR (Timed Eclipse Power Regulation) States are as follows
As of July 6, 1997
  TEPR STATE      Time      TX Status
 ----------------------------------------
       1           n/a         OFF
       2           n/a         OFF
       3           ---         OFF

       4           21          OFF
       5           17          ON at Med Power
       6           ---         OFF

The TEPR States are defined as follows:

Tepr 1, Started when the satellite Enters the Eclipse
Tepr 2, Started at (tepr 1 time) after the satellite enters the eclipse
Tepr 3, Started at (tepr 1 time) + (tepr 2 time) ...

Tepr 4, Started when the satellite enters the Sun
Tepr 5, Started at (tepr 4 time) after the satellite enters the Sun
Tepr 6, Started at (tepr 4) + (tepr 5) ...

TEPR states 1,2 and 3 happen during the Nighttime
passes and TEPR states 4,5 and 6 happen during the Daytime passes. These
occur during EVERY pass, not just over the U.S.A.

The times assigned to the TEPR states are chosen for the health of the
satellite over operation convenience.  Therefore, during parts of the year
the satellite will turn on late or turn off early as seen by ground stations.

Users are asked not to transmit on 145.85 MHz if they do not hear the
satellite's downlink so as to avoid possible interference to other
satellite uplinks and downlinks on adjacent frequencies.

WEEKLY SATELLITE REPORT PT 2

BID: $ANS-222.07

AO-10
(Uplink 435.030-435.18 MHz CW/LSB, Downlink 145.975-145.825 MHz
CW/USB)
Operational. Very active over North America, with strong downlink
signals

OSCAR-11
(Downlink 145.825 MHz. FM, 1200 Baud PSK. Beacon 2401.500 MHz..)
Operating normally.

The operating schedule is unchanged.

         ASCII status (210 seconds)
         ASCII bulletin  (60 seconds)
         BINARY SEU (30 seconds)
         ASCII TLM (90 seconds)
         ASCII WOD (120 seconds)
         ASCII bulletin (60 seconds)
         BINARY ENG (30 seconds)

There are  also  additional  status  blocks  after  each  bulletin  is
transmitted, and between ASCII TLM and WOD.

The  mode-S  beacon  is  ON, transmitting an unmodulated carrier, but
telemetry indicates that it has partially failed, and delivering half
power.  Any reports of reception on 2401 MHz.  would be most welcome.
Please e-mail g3cwv@amsat.org.

The 435.025 MHz. beacon is normally OFF.  However it can sometimes be
heard  when  the  satellite is being commanded by ground control, i.e.
within range of Guildford, UK.  When the 435 beacon is  transmitting,
the  145  beacon  is  normally  OFF.   The data transmitted is mainly
binary.

OSCAR-11  users  are  welcome to visit Clive Wallis' web site.  It contains
some software for capturing data, and decoding ASCII  telemetry and WOD.
There  is  an archive of raw data (mainly WOD) for analysis, which is
continually being expanded, as new data is captured. The URL is -

AMSAT-OSCAR-16 (PACSAT)
(Uplink 145.9, 145.92, 145.94, 145.86 MHz FM, 1200 bps Manchester FSK
Downlink 437.0513 MHz SSB, 1200 bps RC-BPSK 1200 Baud PSK.
Beacon 2401.1428 MHz.)
Operating normally.
Graphic information about WOD/Telemetry values can be found at:

[ANS thanks Miguel A. Menendez, EA1BCU, for this report.]

DO-17(DOVE)
( Downlink 145.825 MHz FM, 1200 Baud AFSK.
Beacon 2401.220 MHz.)
The DOVE s-band signal is 1200 PSK with no carrier suppression.  The
modulation is about 20 dB below the carrier.  You should hear what sounds
like a carrier with lots of Doppler.  If you receive equipment is working
well you will hear the 'buzz' from the flags and an occasional change in
the sound of that modulation as a telemetry beacon is sent.  If it's
working really well and you run the received audio through a PSK demod
then a tracking notch filter (DSP) you will clearly hear the flags and
modulation. In the northern hemisphere there will be deep fades about
every 30 seconds due to the rotation of the satellite.  In the southern
hemisphere there will probably be some fades but not nearly as deep
because the antenna points down when below the equator.

WEBERSAT (WO-18)
(Downlink 437.104 MHz SSB, 1200 Baud PSK AX.25.)
