OSCAR-11 Report March 27, 2006

AMSAT News Service Bulletin 092.04
April 2, 2006
BID: $ANS-092.04

The following OSCAR-11 report was provided by Clive, G3CWV:

On 01 March OSCAR-11 achieved 22 years in orbit, and in spite of numerous problems, it still continues to transmit good signals.

During the period 14 February to 26 March 2006 the VHF beacon on 145.826 mHz. has been heard from 22 February to 04 March, and from 14 to 24 March.

Signals have been very consistent and excellent copy has been obtained on all passes received. If the current mode of operation continues, the beacon should switch ON around 04 April 2006.

The on-board clock continues to show a very large accumulated error. On 24 March it was 22.14308 days slow. However, the clock is now very stable. During the last month it gained 2.5 seconds, which is approximately half the monthly gain, observed when the satellite was fully operational! The observations of clock errors suggest that the clock may slow or stop when the battery voltage is low.

All the analogue telemetry channels, 0 to 59 are zero, i.e. they have failed. The status channels 60 to 67 are still working.

The satellite is now in continuous sunlight until around 06 May, when eclipses will start again. This should help the satellite to continue transmitting, although continuous sunlight can cause problems due to excessive temperatures. Power supply problems can be caused by poor pointing attitude, i.e. the sunlight illuminating the ends of the satellite, instead of the solar arrays.

The watchdog timer now appears to have resumed operation on the 20 day cycle. During the last two months the ON/OFF times have been very consistent, and many observations show this to be 20.7 days, i.e. 10.3 days ON followed by 10.4 days OFF. However, at any time, poor solar attitude, and battery problems, may result in a low 14 volt line supply, which may cause the beacon to switch OFF prematurely, and reset the watchdog timer cycle.

I am indebted to Bob, G4VRC, Gustavo, LW2DTZ, Mike, DK3WN, John, K7RQN and John, G4PWG for their reception reports. All have reported good signals from the VHF beacon. Many thanks for those reports.

The Beacon frequencies are -

VHF 145.826 mHz. AFSK FM ASCII Telemetry

UHF 435.025 mHz. OFF

S-band 2401.5 mHz. OFF

Listeners to OSCAR-11 may be interested in visiting my web site which contains an archive of news & telemetry data. It also contains details about using a sound card or hardware demodulators for data capture. There is software for capturing data, and decoding ASCII telemetry. The URL is:

11. Student Inspired by Amateur Radio Contact

A student who participated in a SAREX contact with astronaut Ken Cameron in 1994 is now an Air Force Academy graduate. She dreams of becoming an astronaut and attributes much of her interest in flying to her participation in that contact years ago. As a little girl, she was able to ask her question, "How does a fish swim in space?" Today she is a pilot and she continues her flight training in flying fighter jets.

Space Probe VOYAGER 1 Received by AMSAT-DL Group

AMSAT News Service Bulletin 092.06
April 2, 2006
BID: $ANS-092.06

On March 31, 2006 an AMSAT-DL/IUZ team received the American space probe VOYAGER 1 with the 20 m antenna in Bochum. The distance was 14.7 billion km. This is a new record for AMSAT-DL and IUZ Bochum. The received signal was clearly identified through means of Doppler shift and position in the sky. The receive frequency was exactly measured and compared with the information provided by NASA.

This distance equals approximately 98 times the distance between Earth and Sun. VOYAGER 1 is the most distant object ever built by mankind. This again proves the superior performance of the Bochum antenna. Most probably this is the first time VOYAGER 1 has been received by radio amateurs.

VOYAGER 1 was launched on September 5, 1977 by NASA. It transmitted the first close-up pictures of Jupiter and Saturn. In 2004 VOYAGER 1 passed the Termination Shock Region, where the solar wind mixes with interstellar gas. VOYAGER 1 today is still active, measuring the interstellar magnetic field.

The following radio amateurs were involved:

Freddy de Guchteneire, ON6UG
James Miller, G3RUH
Hartmut Paesler, DL1YDD
Achim Vollhardt, DH2VA/HB9DUN

Special thanks to Thilo Elsner, DJ5YM of the IUZ Bochum, Roger Ludwig of Jet Propulsion Laboratory (JPL), Pasadena USA and the Deep Space Network Tracking Station in Madrid, Spain for their cooperation.

BID: $ANS-092.07

A coordinated effort by AMSAT-Florida is underway to establish a regional AMSAT net in Central Florida. The Central Florida AMSAT Net began operation last Thursday, March 30 at 19:30 ET on the N4HHA 443.100 mHz repeater located in Orlando, and will continue meeting every week on this same day and time. Preparations are being made to link the Orlando repeater to the NI4CE repeater system that provides coverage throughout west central Florida. More information on this network may be found at www.ni4ce.org. When completed the net should be accessible from a large portion of Central Florida, and in many areas on multiple frequencies. Future plans call for the net to be available via Echolink.

Special thanks go out to the owners and operators of the repeater systems on which the net is held, without which this net could not be possible.

Amateur Radio Satellite News Archive Announced

AMSAT News Service Bulletin 092.08
April 2, 2006
BID: $ANS-092.08

For many years, Richard, G3RWL prepared monthly bulletins of Amateur Radio Satellite news. The bulletins were usually broadcast on the last Sunday of each month, in the AMSAT-UK 80 meter net. They were also distributed via packet radio and as hard copy. Many of the early bulletins were produced before the internet was available.

Clive, G3CWV, has now obtained a complete set of these bulletins which were broadcast from May 1985 to July 2004

This is a very detailed and useful archive, especially for research and preparation of lectures. The archive comprises 239 text files, one for each month, which are zipped into four packages for convenience. Also included are some reports of the AMSAT-UK Colloquium and reports about individual satellites.

Upon making the archives available, Clive stated "I would like to congratulate Richard for a fine achievement in preparing these bulletins and to thank him for granting permission to distribute the archive."

The archive may be downloaded from Clive's web site. See:
