Status: Operational
AO-51 is currently in PBBS mode only using the V/U digital AX.25 mode so that it may provide support for tsumani recovery efforts in South Asia. Please see the Echo operational schedule for additional information.
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 Beacon |
29.502 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.

|
| Telemetry |
145.826 MHz FM 1200 bps AFSK |
| Beacon |
2401.500 MHz Carrier |
| Launched |
1 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.

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.

436.795 MHz FM |
| Launched |
26 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

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.

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 site at http://pcsat.aprs.org.

20 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.

Flight Engineer Salizhan Sharipov
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.

SSETI Express is nearing completion at the ESA technical centre in the Netherlands. Data modes will be primarily used for downlinking telemetry and data from the satellites experiments. ESA will be providing telemetry capture software for amateurs to use and will be offering a prize to the amateur station who provides them with the most telemtry after launch. The mode U/S FM voice transponder will require 67Hz tone access in a similar way to AO51 and will provide three channels of 256 bit telemetry encoded as DTMF tone bursts. S Band output is 3 Watts to 3 x 8dBic RHCP patch antennas. Launch is currently scheduled for not earlier than 18th May 2005. Latest information including integration photographs and a webcam in the cleanroom is at http://www.sseti.net - click on "missions" and then "express".
