Sounds from Amateur Radio Satellites 1996-2005

 

This section is dedicated to satellites built and operated by Radio Amateurs. Satellites built by AMSAT organizations around the world and were called AMSAT-OSCAR. Those built by Russian Hams and were mostly called Radiosputnik. In order to build and launch the satellites AMSAT needs members and friends to contribute and raise funds. If you are not yet a member of AMSAT please consider to join us and to support the activities. You can find several links to AMSAT on my links page.

Fuji OSCAR 29
JAS-2
#24278
(1996-046B)

Fuji Oscar 29 is a LEO (low earth orbit) satellite with a size of 44cm width and 47cm height. Its weight is 50 kg. The communication systems include beacons, a digital store-and-forward BBS message system, an analog communications transponder and Digi-Talker.
The beacons are:
- 435.795 MHZ - CW beacon with 12 wpm and 100mW output
- 435.910 MHz - PSK digital or Digi-Talker
The analog transponder (JA, 1 Watt) uses the following frequencies:
- 145.900-146.000 MHz uplink
- 435.800-435.900 MHz downlink (inverted)
The digital transponder (JD, 1 Watt) uses the following frequencies:
- 145.850 MHz, 145.890 MHz, 145.910 MHz 1200bps AFSK uplinks
- 145.870 MHz 9600bps FSK uplink
- 435.910 MHz 1200bps BPSK or 9600 bps FSK downlink
- 435.910 MHz Digi-Talker FM Downlink

Synthesized voice running twice as fast as it should be, recorded by KD4APP on Aug 24rd 2003

After a long period of deactivation in January 2010 the analog transponder of FO-29 with a downlink transmit power of 5W was switched back on. Excellent signals were reported as demonstrated also in enclosed recording of a SSB contact of SQ7DQX and PE0SAT. Recorded on January 29th by Matt SQ7DQX.

On December 30th 2014 at 20:00 UTC Roland PY4ZBZ and Luciano PY5LF managed to have a contact in CW via a cross-satellite link via FO-29 and AO-7. PY5LF transmitted on 432.150 MHz to AO-7 in CW mode. AO-7 retransmitted the CW signal on 145.950 MHz which was received by FO-29. Finally FO-29 retransmitted the signal on 435.850 MHz which was received by PY4ZBZ.Please note that Doppler shift was minimum as the satellite transponders are inversed and thus compensated nicely.Audio recording and spectrogram screenshot kindly provided by Roland PY4ZBZ.

Mexico OSCAR 30
UNAMSAT-B
#24305
(1996-052B)

Mexico OSCAR 30 was a LEO (low earth orbit) satellite and a secondary payload launched with COSMOS 2334 (Parus #86).
MO-30 was built by the Autonomous University of Mexico (UNAM). This Cubesat had the size of 15x15x15cm and a weight of 10.7kg. The successful launch followed the unsuccessful launch and destruction of UNAMSAT-A in 1995..
It featured a store-and-forward PACSAT protocol suite communication system. The uplink was 1200 bps AFSK on 145.815 MHz, 145.835 MHz, 145.855 MHz ad 145.875 MHZ. The 1200bps BPSK downlink with a transmit power of 200-300mW was on 437.206 MHz (with a secondary downlink on 435.138 MHz). UNAMSAT-B operated for 46 days sending telemetry. Due to a flaw in the receiver the satellite did not receive ground commands which were necessary to stabilize the satellite's orbit.

Enclosed audio recording of MO-30 is from an unknown source.

Mar 4th 1997

RS 17
Sputnik-40
Sputnik-Jr
#24958
(1997-058C)

In memoriam to the first man made satellite Sputnik-1, which was successfully launched 40 years before, this little satellite was launched by hand during an EVA (Extra Vehicular walking in space) from the MIR space station. The RF signal sounded like a beep-beep as the transmitter with a power of 100 to 200 mW was keyed on/off. The RF carrier on 145.820 MHz was FM modulated and the frequency of the audio signal varied with the temperature inside the satellite. Recorded in FM on November 3rd 1997 12:45 UTC by IK1SLD. For confirming the reception by a QSL card the award was given.

Nov 16th 2000

The 2m beacon signal was recorded by DK3WN on November 17th 2000 08:30 UTC when AO-40 was in a distance of 43000km.

The UHF-SHF transponder of AO-40 had an excellent performance. Enclosed contact of W7LRD and VE2DWE was recorded on August 26th 2002 by VE2DWE. He used for the 435 MHz UHF uplink 5W and a 40 element crossed yagi and for the L-band downlink a BBQ grill antenna with an AIDC 3733 2.4 GHz downconverter. Recording kindly provided by VE2DWE.

Telemetry beacon recorded by DJ1KM, member and strong contributor to AMSAT-DL. Reinhard passed away in Oct 2006.

QSO of Don KD4APP and Stuart GW3XYW, recorded by Don on March 11th 2003. Kindly provided by Don KD4APP.

QSO of Frank DL6DBN and Andreas OE1DMB in German language. Recorded and kindly provided by OE1DMB.

AO40 transmitted its 400 bit/s beacon also on the 24 GHz downlink. Note the spin fading due to the fact, that both, the receive system and the 24 GHz transmitter, used linearly polarized antennas. Received and kindly provided by Michael OH2AUE.

In this recording you can hear the CW signal of DK1KQ on the 24 GHz downlink while he was using the L-band uplink. Received and kindly provided by Michael OH2AUE.

Michael also copied DB6NT in SSB on the 24 GHz downlink while he was using the L-band uplink. Recorded and kindly provided by Michael OH2AUE.

On May 7th 2002 the U/K-band transponder was used by Charles G3DWG and Mike N1JEZ for the first transatlantic QSO with a joint 24GHz downlink. Please note the rather low doppler shift due to the fact that they used the transponder while AO40 was at apogee (distance was about 61000 km). The output power of the K-band transmitter was estimated to have dropped to about 600-800mW. Recorded and kindly provided by Mike N1JEZ.

On February 23rd 2003 the S1/K-band transponder was tested. In enclosed recording of the 24 GHz downlink you can hear Charles G3DWG and Domenico I8CVS + testing the SSB transponder. Charles was transmitting on the U-band uplink while Domenico was transmitting on the S1-band uplink at 2401 MHz (10 Watt into a 1.2m dish). Recording kindly provided by Mike N1JEZ.

This is a contact between I8CVS +, IW1ERR and I5UXJ during orbit 867 and MA241 on September 20th 2002. Uplink was at 1268 MHz, downlink was at 2401 MHz (Mode L/S). Recorded and audio file kindly provided by Domenico I8CVS +.

This are another 2 contacts on August 31st 2002 in LS-Mode. The first is between Jon ZS6JON and Frans PA3CQE, the second is between Jon JS6JON and Rob PE1ITR. The contacts were recorded by Frans PA3CQE. Audio file kindly provided by Rob PE1ITR.

Her are some very special goodies. They were not recorded while AO40 was in orbit but during the various integration tests and the final prelaunch tests in Kourou.
The first audio file is a test of the LEILA function in CW conducted by OH2AUE during pre-launch tests.
The second audio file is a test of the LEILA function in SSB conducted also by OH2AUE in Kourou.
The third audio file was a test of the built in microphone of AO40 by DB2OS (tapping the support frame).
The forth audio file was another test of the micro. You can hear Peter DB2OS "talking to the bird".
The fifth audio file was a test of the microphone already done during one of the integration tests in Florida. All three momentum wheels have achieved synch to the programmed test values. Analyzing the audio spectrum with a PC FFT program you can see the frequencies and thus calculate the rotation speed of the wheels directly.
The sixth audio file is the 400bd PSK beacon recorded during thermal vacuum tests in Virginia.

The seventh audio file is also the 400bd PSK beacon received on 70cm band during tests on June 26th 1999. If you decode this file with the AO40RCV freeware then you can decode 4 blocks of data which I enclose also a s a text file.

This is the last special from AO-40. You can decode this audio file with the P3T software. The result is great fun as you can see from the telemetry that all RF transmitters are turned OFF, only the IR laser is turned ON. This was probably the only time that the IR laser was ever actually received and demodulated + decoded. The laser was never tested in space. Michael OH2AUE made this recording during the launch preparation and final tests in Kourou.

All these recordings were kindly provided by Michael Fletcher OH2AUE.

This first pan-European student micro-satellite was built by a distributed team of university students and radio amateurs throughout Europe. It was sponsored by ESA and launched together with 5 Cubesats on a russian rocket KOSMOS-3M (ROCKOT) from the Plesetsk Cosmodrome in Northern Russia. The amateur radio payload had downlinks on 437.250 MHz (FSK, 9k6 AX.25) as well as 2401.835 MHz (FSK, 38k4 AX.25, 3 Watt).

Oct 27th 2005

 Unfortunately the satellite was operational only for 5 orbits and then shut down due to a lack of power. The 9600bd packets transmitted every 18 seconds were recorded on October 27th 2007 at 09:13 UTC on 437.250 MHz in FM by Ian Ashley ZL1AOX. Besides you can also read the decoded data of this transmission.

This is a recording of the "safe mode" pulse beacon. This came on when the battery volts fell too low for the main system to operate and was heard by a number of amateurs. Recording kindly provided by Graham G3VZV.

The enclosed audio file is a test of SSETI Express in the "UHF-S Band FM voice transponder" mode. It was performed at ESA ESTEC facilities during integration and test of the satellite sub systems. The test was performed on February 23rd 2005 at 22:31 UTC by Graham Shirville PA0/G3VZV. Many thanks to Graham for providing this unique recording.
