SSTV ON RS-12/13 MODE KT

SSTV Enthusiasts Send Pictures Through RS-12/13

VE4AMU reports that there are several RS-12/13 users who are currently
sending SSTV pictures through RS-12/13.  RS-12/13 is in Mode KT and VE4AMU
says that the SSTV modes used are the 12, 24, and 36 second ROBOT color and
AVT 24.  VE4MAU notes that it is a little harder to send pictures through
RS-12/13 because of the doppler-shift one encounters with this "low-earth-
orbiting" OSCAR.  Also, he says you should expect some "noise" mixed in with
the picture on the downlink frequency of 29.440 MHz.  VE4AMU wants to
invite all SSTV and RS-12/13 enthusiasts to join him on an uplink of 21.240
MHz, with the downlink signal on 29.440 MHz, +/- doppler.  If you would
like to set-up a schedule with VE4AMU for SSTV operations on RS-12/13, send
him a message to his local packet radio BBS: VE4AMU@VE4KV.#WPG.MB.CAN.NOAM.
For more information about SSTV in general, see the January '93 issue of
QST or join the SSTV Net on Saturday mornings at 14.230 MHz where pictures
and information is exchanged.

[The AMSAT News Service (ANS) would like to thank VE4AMU for this bulletin
item.]

AMSAT OPERATIONS NET SCHEDS

AMSAT-NA Operations Net Schedule

AMSAT Operations Nets are planned for the following times.  Mode B Nets
are conducted on AO-13 on a downlink frequency of 145.950 MHz and the Mode
J/L Nets on a downlink of 435.970 MHz.

 Date           UTC    Mode     Phs       NCS     Alt

 11-Jan-93       0400   B        21      W9ODI   N7NQM
 16-Jan-93       2200   B        36      W5IU    WA5ZIB

Any stations with information on current events are especially welcomed
to join the AO-13 Operations Net.  In the unlikely event that either the
Net Control Station (NCS) or the alternate do not call on frequency, any
participant is invited to act as the NCS.

Slow Scan Television on AO-13

SSTV sessions will be held on Saturdays and Sundays (UTC) at Mean Anomaly
count 50.  The downlink is on Mode B only at 145.960 MHz.  OPSNETS will
take priority so look for SSTV activity immediately after they conclude.

CURRENT OSCAR STATUS REPORT

HR AMSAT NEWS SERVICE BULLETIN 002.03 FROM AMSAT HQ
SILVER SPRING, MD JANUARY 2, 1993     BID: $ANS-002.03
TO ALL RADIO AMATEURS BT

Current OSCAR Status Reports: 01/02/93

FO-20: Date: 01/02/93: FO-20 is in Mode JA SSB mode on Wednesdays UTC.  At
all other times the Mode JD BBS will be in operation.  Mode JA Uplink pass-
band is 145.900-146.000 MHz.  Downlink passband is 435.900-435.800 MHz.
Mode JA is an inverting transponder.  The Mode JA beacon can be heard at
435.795 MHz.  [G3IOR]

AO-13: Date: 12/26/92: PLEASE NOTE THE FOLLOWING MESSAGE FROM VK5AGR:
L de VK5AGR 25-DEC-92 21:00 UTC - The last session of magnetorquing
to change AO-13's attitude from 134/6 to 130/0 commenced on
25-DEC-92 at 21:04 UTC i.e. Orbit 3471 MA 237. As the Sun Angle has
been sitting around the -40 to -45 degrees, the Mode-B transponder
operation has had to be restricted to 55 MA units. After the
completion of this 1 perigee magnetorque the Sun Angle will
steadily improve each day so full Mode-B operation will be
reintroduced as soon as possible. In the interim Mode-B will be
switched ON from MA 15 to MA 90 and again from MA 170 to MA 240.
The omnis will be ON from MA 170 through perigee to MA 15.
Don't rely on gossip and rumor! Continuous up-to-date information
about AO-13 operations is always available on the beacons, 145.812
MHz, 435.658 MHz and 2400.646 MHz in CW, RTTY and 400 bps PSK.


KO-23: Date: 01/02/93: Operating normally.  No images as of 12-Dec-92.
The AMSAT Keps in $ORBS-333 are GOOD for KITSAT as Object #22077.  [WH6I]

AO-16: Date: 01/02/93: Operating normally with the new software.  Using
raised cosine transmitter with a downlink frequency of 437.050 MHz. [WH6I]

LO-19: Date: 01/02/93: Operating normally with broadcast bulletins on
Mondays.  [WH6I]

UO-22: Date: 01/02/93: WH6I reports that UO-22 appears to be operating
normally this past week0.  [WH6I]

UO-11: Date: 12/26/92: G0/KO5I has uploaded a new bulletin on UO-11 dated
15-DEC-92. Monitor UO-11's telementry beacon on 145.820 MHz.  [G3IOR]

AO-21: Date: 01/02/93: Good signals from the the CW beacon on the 22-Dec-92
but no audio or AFSK packet transmission on the 2M downlink frequency of
145.987 MHz.  AL7MK tried to make a voice transmission but without success.
[AL7MK]

RS-10/11: Date: 01/02/93: RS-10/11 is still send its Christmas message on
the CW telemetry channel.  AL7MK reports that he made many contacts with
west coast stations from his QTH in Alaska on this Mode A OSCAR.  [AL7MK]

RS-12/13: Date: 01/02/93: AL7MK worked west coast stations when the band
conditions on 15M were "dead."  Witen 15M is open, too many "incidental"
stations are heard through RS-12/13 because these stations are unaware that
they are in the satellite's uplink passband.  This makes it difficult to
"sort" out who is really on RS-12/13.  [AL7MK]

The AMSAT NEWS Service (ANS) is looking for volunteers to contribute weekly
OSCAR status reports.  If you have a favorite OSCAR which you work
regularly and would like to contribute to this bulletin, please send in
your observations to WD0HHU at his CompuServe address of 70524,2272, on
INTERNET at wd0hhu@amsat.org, or to his local packet radio BBS in the
Denver, CO area, WD0HHU @ W0LJF.#NECO.CO.USA.NOAM.  Also, if you find that
the current set of orbital elements are not generating the correct AOS/LOS
times at your QTH, PLEASE INCLUDE THAT INFORMATION AS WELL.  The
information you provide will be of value to all OSCAR enthusiasts.
