AMSAT-OSCAR 51 or Echo as it is more commonly known is a FM
satellite carrying 4 VHF receivers, 2 UHF transmitters, a multimode
receiver and a 2400MHz transmitter. It can handle voice and FSK data
up to 76.8Kbps. Echo was launched into a low, sun-synchronous polar
orbit approximately 850 km high. You must transmit a 67Hz PL tone in
order to access the Echo voice repeater.
Please note the change in operational phone downlink frequency to
435.300 MHz.

Mode A Downlink29.40 - 29.50 MHz CW/USB (non-inverting)
Mode A Beacon29.502 MHz (CW telemetry)
Launched 15 November 1974
Status: Semi-operational
AO-7 became non-operational in mid 1981 due to battery failure . In
2002 one of the shorted batteries became an open and now the
spacecraft is able to run off solar panels. For this reason it is
not usuable in eclipse and may not be able to supply enough power to
the transmitter to keep from frequency modulating the signal. Lately
AO-7 has favored Mode B almost exclusively.
Mode A is equivalent to Mode V/A
Mode B (8 Watts PEP) is equivalent to Mode U/V
Mode C is the same as Mode B however the power is 2.5 Watts PEP
There is also a 13 cm beacon at 2304.1 MHz, however this does not
get turned on as it is outside the Amateur allocation for 13 cm.
UoSat OSCAR 11 (UO-11)
Telemetry145.826 MHz FM 1200 bps AFSK
Beacon2401.500 MHz Carrier
Launched1 March 1984
Status: Semi-operational
OSCAR-11 now operates in a default mode, controlled by the watch-dog
timer. The satellite transmits continuous ASCII telemetry for about
10 days on 145.826 MHz., followed by about 10 days of silence. This
regular sequence might be interrupted by ground control, at any
time.
The mode-S beacon is ON continuously, even when the VHF beacon is
OFF, nominally transmitting an unmodulated carrier on 2401.5 MHz.
There is however a VERY low level of AFSK modulation, (now a
constant audio tone), which has been detected on strong signals.
Telemetry indicates that the beacon has partially failed, and is
delivering half power.
Radio Sport -15 (RS-15)
Uplink145.858 to 145.898 MHz CW/USB
Downlink29.354 to 29.394 MHz CW/USB
Beacon29.352 MHz
Launched26 December, 1994
Status: Semi-operational
RS-15's beacon is occasionally heard and may be quite strong at
times. At times the beacon is just a continuous carrier lasting up
to 30 seconds, at other times it seems to be sending CW. There have
been a few reports of hearing CW through the passband and Al N7EQF
has reported having a CW QSO.

AMRAD OSCAR 27 (AO-27)
Uplink145.850 MHz FM
Downlink436.795 MHz FM
Launched26 September 1993
Status: Operational
The AO-27 Team has reported that a new schedule has been uploaded.
If the batteries hold then it should continue to run. If the
batteries get too low then the software will turn the schedule off
and the control operators will have to compute another one. The
current schedule indicates that AO-27 is turned on for analogue
operations during a 6 minute pass on the ascending pass. As in the
past, the analogue mode is preceded and followed by 1 minute of
digital TLM. A TLM stream is also transmitted for one minute on the
decending pass.
The latest information on AO-27 from control operator Michael
Wyrick, N3UC (former N4USI), can be found at http://www.ao27.org/

Currently software is being uploaded to address software defects
that were uncovered, however the GO-32 team is very responsive and
outages have been quickly addressed. The GO-32 BBS server software
and other improvments became operational as of July 1, 2004. Emily,
W0EEC has reported that she was able to connect up to the BBS. Users
might be able to communicate GO-32 while the BBS is on and enabled.
Check the GO-32 Site and GO-32's beacons for updates.

APRS Downlink144.390 MHz FM (Region 2)
Launched30 September 2001
Status: Semi-operational
NO44 is going through periods of being non-operational and being
operational in sunlight. Its battery is too soft to provide the peak
current necessary to transmit a packet. It can still be heard
occassionally when sun angles are right (local noon in the northern
hemisphere), but cannot be used with any reliability. Users are
requested to not UPLINK to give better chance that control stations
can continue to control it. (Status provided by Bob, WB4APR, 13 July
2004). For more information visit the PCsat Website.
NO-44 is a 1200-baud APRS digipeater designed for use by stations
using hand-held or mobile transceivers. Downlinks feed a central web

Saudi-OSCAR 50/SaudiSat 1C (SO-50)
Uplink145.850 MHz FM
Downlink436.795 MHz FM
Launched20 December 2002
Status: Operational
SO-50 carries several experiments, including a mode J FM amateur
repeater experiment operating on 145.850 MHz uplink and 436.800 MHz
downlink. SO-50 is operational for 10 minutes when turned on by the
following procedure:
1) Transmit for 1-2 seconds on 145.850 MHz with a tone of 74.4 Hz to
arm the 10 minute timer on board the spacecraft.
2) Next transmit on 145.850 MHz (FM Voice) using 67.0 Hz to key the
repeater on and off within the 10 Minute window.
Note: Sending the 74.4 tone again within the 10 minute window will
reset the 10 minute timer.

Status: Operational
The ISS system has sometimes been turned on to Cross Band Repeat
mode. In this mode it functions as a Mode B-FM repeater. Amateurs in
the US and elsewhere have reported using the repeater with home
stations and handheld radios with great success. The crew is also
able to use the radio to transmit even when the system is in this
mode.
While the system is in cross band repeat mode the packet system is
turned off and vice-versa.
The ISS daily crew schedule can be found at
http://spaceflight.nasa.gov/station/timelines/. Remember that the
crew operates on UTC time. Also, all of the time line is NOT
translated from Russian and posted.
Current ARISS News is available at the ARISS page in this website.
