AMSAT NEWS SERVICE BULLETIN 012.S2 FROM AMSAT HQ
SILVER SPRING, MD, JANUARY 12, 2003
TO ALL RADIO AMATEURS
BID: $ANS-012.S2
OSCAR-11
Downlink: 145.826 MHz FM (1200-baud AFSK)
Mode-S Beacon: 2401.500 MHz
Launched: March 1, 1984 by a Delta-Thor rocket from Vandenberg Air
Force Base in California. Status: Semi-operational.
OSCAR-11 is currently operating in a default mode, controlled by the
watch-dog timer. The satellite transmits continuous ASCII telemetry
for about seven days on 145.826 MHz, followed by about 14 days of
silence. The mode-S beacon on 2401.500 MHz is ON continuously.
At the present time, ground control are unable to command the
satellite, due to low temperatures affecting the command decoder.
They will attempt to command the satellite when the command decoder
temperature has risen to 15C.
The following operating schedule is currently suspended.
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)
The ASCII bulletin is currently a static message, detailing modes and
frequencies of all active Amateur Radio satellites.

(using 1200-baud Manchester FSK)
Downlink: 437.026 MHz SSB (1200-baud PSK)
Mode-S Beacon: 2401.1428 MHz
Broadcast Callsign: PACSAT-11
BBS: PACSAT-12
Launched: January 22, 1990 by an Ariane launcher from Kourou,
French Guiana. Status: Semi-operational, the digipeater command is on.

UOSAT UO-22
Uplink: 145.900 FM 9600-baud FSK
Downlink: 435.120 MHz FM
Broadcast Callsign: UOSAT5-11
BBS: UOSAT5-12
Launched: July 17, 1991 by an Ariane launcher from Kourou,
French Guiana. Status: Operational.
Several have reported not hearing UO-22.
On November 21, 2002 Chris Jackson, G7UPN reported:
UO-22 is operating OK at the moment. Some new software has been loaded to
try and keep the downlink operating most of the time. It seems that after
around 60000 charge/discharge cycles the Nicad batteries are starting to
show their age!
The downlink will be switched off from time to time over certain parts
of the globe. This is required to allow the attitude control system to
operate correctly since the power system cannot supply enough power to
support both the transmitter and the magnetorquers.
More information on the satellite is available at the following URL:

and Jim Weisenberger, AA7KC, for status information]

ITAMSAT IO-26
Uplink: 145.875 145.900 145.925 145.950 MHz
FM (1200-baud)
Downlink: 435.812 MHz SSB
Broadcast Callsign: ITMSAT-11
BBS: ITMSAT-12
Launched: September 26, 1993 by an Ariane launcher from Kourou,
French Guiana. Status: Semi-operational, the digipeater function is on
and open for APRS users.
On November 18, 2002 Alberto, IK2BD reported:
The current configuration of IO-26 allows only limited telemetry in MBL
(safe)
mode. To enable full telemetry and digipeating, we must re-load the full IHT
high level software suite. This was delayed several times, but we plan to do
that in the near future. When the IHT code is running, the bulletin will
announce that.

IO-26 information]

PCSAT NO-44
Uplink/downlink: 145.827 MHz 1200 baud AX-25 AFSK via W3ADO-1
Aux/Uplink: 435.250 MHz 9600 baud via PCSAT-2 (off)
APRS Downlink: 144.390 MHz (Region 2)
Launched: September 30, 2001 aboard an Athena-1 rocket from the
Kodiak, Alaska launch complex. Status: Operational.
PCSat is a 1200-baud APRS digipeater designed for use by
stations using hand-held or mobile transceivers. Downlinks feed a
central web site < http://pcsat.aprs.org >. The APRS-equipped
PCSat was built by midshipmen from the U.S. Naval Academy
under the guidance of Bob Bruninga, WB4APR.
A new version of PCSAT.EXE has been posted at:

Broadcast callsign: MYSAT3-11
BBS: MYSAT3-12
Launched: September 26, 2000 aboard a converted Soviet ballistic
missile from the Baikonur Cosmodrome. Status: Operational at

AO-49 RUBIN-2 (SAFIR-M)
Uplink 435.275 1200-baud AX.25
Downlink 145.825 9600-baud AX.25
(optional voice message)
Broadcast callsign: DP0AIS
Launched: December 20, 2002 aboard a converted Soviet ballistic
missile from the Baikonur Cosmodrome. Status: Operational.
"SAFIR-M" is a German amateur radio payload onboard the small German
scientific satellite "RUBIN-2".
SAFIR-M was built by the German amateur radio association
"AATiS e.V." (German acronym for "Arbeitskreis Amateurfunk
und Telekommunikation in der Schule", which means: 'working group
for amateur radio and telecommunications in schools').
SAFIR-M is designed as a "store and broadcast" system for APRS
based messages, dedicated for the use of schools in combination
with the existing WX-Net and planned buoy experiments in Germany.
Martin DG8UAU has written a small software program "SAFIR-M Decoder"
to allow decoding of the received DATA0 frames. It is available at:
http://amend.gmxhome.de in the section Aktuelles.
Details on SAFIR-M can be found at:
