Software Defined Transponder Prototype On-the-Air

AMSAT News Service Bulletin 233.04
August 21, 2005
BID: $ANS-233.04

At the labs of CNS Systems, Inc. in Md.  (W2GPS business), W2GPS, W3IWI,
and N4HY made the first on-the-air tests using a prototype software
defined transponder on 16 August 2005. A sucessful three way QSO was
conducted in a 45 Khz wide transponder. An audio clip of this first QSO
is available at 

At the AMSAT Symposium in Louisiana, the plan is to have both the Mode B
and the Mode A transponder fully functional and usable by all.   We will
show the power of using software defined radio for the transponders by
having 1/2 of the transponder divided into two or three FM channels and
the other half fully linear whilst adding 400bps AMSAT standard beacon
in the middle, AND on command, switch it to fully linear, etc.

We will incorporate the Stella AGC algorithms developed by Howard,
G6LVB, adapted to our hardware for the demonstration in Lousiana.
Expect to be able to conduct SSB, CW, FM, etc. QSO's on Mode A, Mode B
and Mode LS if time permits.

AMSAT Website Technical Review Team Formed

AMSAT News Service Bulletin 233.05
August 21, 2005
BID: $ANS-233.05

Barry Baines, WD4ASW, AMSAT's VP-Marketing & User Services is pleased to
announce that our Website Technical Review Team, under the leadership of
Gould Smith, WA4SXM has been formed.  Gould serves as Director-Field
Operations and is the author of a number of AMSAT books.  He is well
qualified to handle this important task with the assistance of a very
capable team that he has formed.  The team that Gould has developed
consists of AA2TX, KO4MA, KQ6EA, N8FGV, and VA3DB.

The team has begun a systematic look at the content of the AMSAT website
for technical issues, and is assigning a priority to identified items.
The first areas the team is addressing are the Glossary and the Mode J
operation article.  When appropriate, they will seek input from other
individuals who may be knowledgeable in particular areas.  Two members
of the team will OK articles for technical content with final approval
from Gould before he forwards them for inclusion on the website.

"Our team is excited about updating the technical content of our
website" says Gould Smith, WA4SXM.  "However, this will take some time
and will require thoughtful evaluation.  In looking at the Glossary for
example, we have found through our initial research that even the
experts sometimes disagree on proper definition of technical terms.  We
want the AMSAT website to be a trusted and reliable source."

Emily Clarke, W0EEC serves as Director-Website and will be working
closely with Gould to implement changes as they are developed.

Should website visitors wish to suggest areas of current website
technical content for the team's consideration or are interested in
submitting suggested technical changes or updates, they can do so by
contacting Gould Smith, WA4SXM  using his AMSAT e-mail alias.  Please
put 'Website Technical Review' in the subject line.  Gould and  several
members of the team will be attending the AMSAT Symposium in Lafayette,
LA (7-9 OCT 2005) and are interested in hearing comments from attendees
concerning their thoughts on the updating of technical content of our

1. ARISS Student Pursues Astronaut Career

Stephanie Radcliff was a student at Daviess County High School (DCHS) in
Owensboro, Kentucky when the school experienced an ARISS contact on May
31, 2001. She had prepared three questions to ask astronaut Susan Helms,
KC7NHZ, that day, including one concerning future space explorations.

Four years later, on August 12, 2005, Stephanie returned to her alma
mater to speak to the students there. She is now a graduate of
Emory-Riddle University, and holds a degree in the aerospace field.  She
has taken the first steps toward becoming an astronaut and hopes to be
accepted for astronaut training.  Harold Wilson, the coordinating
teacher of the DCHS - ARISS contact, remarked that it was the ARISS
contact which inspired Stephanie to pursue this career choice.

2. PCSAT2/MISSE5 Status

The PCSAT2 PSK-31 transponder was turned on. It uses an uplink on 29.402
+/- 1 KHz and downlink on 435.275 +/- Doppler using FM . For more
information, see: http://www.ew.usna.edu/~bruninga/pec/pc2ops.html 

3. ARISS International Meeting

ARRL ran a story on the ARISS International face-to-face Meeting held at
the University of Surrey. The article, entitled, "ARISS Delegates Urged
to Cast Eye on Future of Ham Radio in Space," may be found on their
website. See: http://www.arrl.org/news/stories/2005/08/12/106/?nc=1

ARISS delegate Rosalie White is currently working on the minutes of the
U.K. meeting. They will be posted on the ARISS and AMSAT websites in the

August 2005.

4. Australian News Article on Astronaut's Father

The Australian newspaper, The Age, ran a story on Adrian Thomas. Thomas,
father of astronaut Andy Thomas, was waiting apprehensively for word of
Discovery's landing. A ham friend of his had been listening to NASA's
channel, and called to let him know that the shuttle was heading for a
safe landing in California.  "Ham radio call ends father's anxious
wait," may be found at:

OSCAR 11 Report - 15 August 2005

AMSAT News Service Bulletin 233.08
August 21, 2005
BID: $ANS-233.08


                   15 August 2005

OSCAR-11 is back! I received the good news, on Saturday morning, while
at the AMSAT-UK Colloquium.  This was entirely unexpected!  On Sunday
morning Bob G4VRC played me a recording of an early morning pass
received that day.

During the period 21 July to 14 August 2005 consistent signals have been
heard from 30 July to 08 August. Signals seem to be weaker than usual,
confirmed by the many reports received. However,since I last heard the
satellite on 30 April, I've reinstalled my antennas , which makes
comparisons difficult.

Many thanks for all the recent reports of OSCAR-11 including those from
KU7Z (who heard it first), KB2M, VK6XH, HK7MKE, KA2UPW, JE9PEL, G1OCN,

All the analogue telemetry channels, 0 to 59 are zero, ie they have
failed.  The status channels 60 to 67 are still working. One bit in
channel 62, DSR mode, has changed from WRITE to READ.  DSR is the
Digital Store & Readout experiment. This could be significant if the
experiment is still drawing current, but the other status bit indicates
that it is switched OFF.

The on-board clock is now showing a very large error.  It has lost
approximately 19 days since 30 April.  During the recent data collection
period, the clock error has been changing at a decreasing rate.  The
size of the clock error and the rate at which it is changing is similar
to the duration of the solar eclipse periods. This suggests that the
clock might have been switching OFF during eclipses.

The eclipses have now ended, and the satellite should be in continuous
sunlight for the remainder of this year, and well into next year.  This
should help the satellite to continue transmitting, although continuous
sunlight can cause problems due to excessive temperatures. 

If the watchdog timer is still operating on a 20 day cycle, ie.
approximately ten days ON followed by 10 days OFF, then the VHF beacon
should resume transmissions around 18 August.

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 website which
contains an archive of news & telemetry data. It also contains details
about using a soundcard or hardware demodulators for data capture.
There is software for capturing data, and decoding ASCII telemetry.  The
URL is www.users.zetnet.co.uk/clivew/

the bulletin identifier $BID:U2RPT112.CWV, to prevent duplication.
