OSCAR-11 Report March 27, 2006
AMSAT News Service Bulletin 092.04
From AMSAT HQ SILVER SPRING, MD.
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:

3. Successful ARISS Contact with Italian School Children
On March 21, children from three schools participated in the ARISS contact
held at 1°Circolo didattico Giuseppe Settanni in Rutigliano, Italy. Two
elementary schools, "1°Circolo didattico Giuseppe Settanni" (500 pupils) and
"2°Circolo didattico Aldo Moro" (475 pupils) and one middle school,
"Alessandro Manzoni" (615 pupils) participated. Bill McArthur, KC5ACR,
answered 17 questions that were relayed to him by amateur radio operator
Michele Mallardi, IZ7EVR. Audio and video links were made from the radio
shack at the "Giuseppe Settanni" school to the assembly halls of the two
other schools where students, teachers, military representatives, civilian
authorities and Princess Elettra Marconi, daughter of Guglielmo Marconi,
watched. Five television stations (RAI3, Telenorba, Telepuglia, Telebari and

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.

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.

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.

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:
