AMSAT at Dayton - Report From the Show

AMSAT News Service Bulletin 140.02
May 20, 2007
BID: $ANS-140.02

As this bulletin is being released AMSAT members are enjoying a fun
filled weekend at the 2007 Dayton Hamvention.  AMSAT is having a
successful weekend showing the amateur radio community our special
aspect of communications while at the same time demonstrating how
satellite techniques are within the reach of interested operators.

Taking up 5 Hamvention booth spaces AMSAT was able to demonstrate
a half scale model of the Eagle satellite, the Eagle 70cm receiver,
a full scale model of the Echo satellite, prototype ARISS antennas 
for the ISS, prototype SuitSat-2 antennas and helmet control box, 
and live tracking software interfaced with a working LVB tracker 
connected between a computer using a serial or USB connector
and the Yaesu 5400/5500 rotor controller box driving an az-el rotor 

AMSAT's latest publications and this year's AMSAT Dayton fashions 
were also available.  These can be ordered via the AMSAT store on 
our web page after the Hamvention.  All of this was brought out
through the efforts of a team of approximately 25 volunteers. 
Thanks a million guys and gals!

After the booth was setup on Thursday afternoon prior to the offical
opening of the Hamvention on Friday, the team enjoyed the annual
AMSAT Pizza 'n Suds party at Marion's Piazza.  This was a well
attended party with about 50 satellite afficionados in attendance.

Keigh Pugh, W5IU coordinated the AMSAT satellite demonstrations. His
team was able to run 6 demonstations on Friday, 7 on Saturday, and
at press time an additional 5 demonstrations were planned for Sunday
morning.  SO-50, AO-7, AO-51, AO-27, and VO-52 were used for QSOs.
Numerous comments were received at the booth about how well the
demonstrations were presented, how remarkably well the signals were
received, and how the individual now better understood satellite
operating having seen it in person.

The AMSAT booth enjoyed a visit from Bill McArthur, KC5ACR, ISS 
Expediton 12 Commander who was at the Hamvention in support of 
planned ARRL activities.

The AMSAT Forum on Friday featured outstanding list of speakers and
topics of interest to all AMSAT members. The forum drew over 100
interested radio amateurs.  Barry Baines, WD4ASW, AMSAT-NA Corporate 
Secretary moderated the session.

The first speaker was Rick Hambly, W2GPS, President, AMSAT-NA who
presented the "Summary of AMSAT-NA Activities in 2007".  Rick re-
minded everyone in attendance of AMSAT's vision of HEO Satellites
are our primary mission.  AMSAT will assist LEO efforts undertaken
by the educational community and other amateur radio groups.

Rick continued with a list of achievements for 2006 including the

 + AO-51 has now passed 2 years of continous operation. Software
   upgrades and testing are now in progress to further improve
   this satellite and the operator's experience.

 + SuitSat-1 captured the world's attention and helped promote
   amateur radio.

 + SuitSat-2 development is currently underway and will feature
   an SDR transponder.

 + AMSAT-NA support for AMSAT-DL's P3E provides funding, and staffing
   for design, testing, and integration.

 + Eagle satellite development is on-going concurrently with P3E
   and the satellites will both share common modules and software.

 + AMSAT's education outreach provides mentoring to student's who
   are designing, building, and launching satellites.

 + The AMSAT Lab in Maryland was opened.  The clean room equipment
   is currently being installed.

Bob McGwier, N4HY, AMSAT VP-Engineering, spoke on behalf of Peter 
Guelzow, DB2OS, to describe progress for AMSAT-DL's Phase 3-Express
(P3E) satellite.  P3E will provide a critical test bed for proof
of concept of critical systems needed for the planned P5A mission
to Mars.  P3E is being built in an AO-13 spaceframe but will feature
new electronics and software.  It will also include the same Soft-
ware Defined Transponder planned for AMSAT Eagle.  Launch oppor-
tunities are currently being explored.

Bob then continued with an Eagle Status Update.  His slides showed
how the Software Defined Transponder will be integrated in Eagle.
He discussed the exceptional increase in radio performance that
the SDX technology will bring.  Details were also discussed about
the HELAPS power amplifier, phased array antennas, and the break-
though with getting the first 70 cm receiver debugged and working
and currently starting performance testing.  Bob described the
features of the Advanced Communication Package.  More details of
Eagle will be provided in future issues of the AMSAT Journal.

Next was Gould Smith, WA4SXM, AO-51 Command Station, who spoke
about "AMSAT-NA Satellite Operations and AO-51 Update."  Gould
descibed the work of the AO-51 Operations Group who are currently
writing and testing new software to be uploaded into AO-51.  He
also gave everyone an overview of an AO-51 command station.

Frank Bauer, KA3HDO, AMSAT-NA Director-Human Space Flight, gave an
impressive presentation of "ARISS and Future SuitSat Missions."
Frank was able to include mission audio clips, SuitSat audio
clips, and NASA video of SuitSat.

According to records, ARISS school contacts from the International
Space Station have reached over 15,000 students.  Also, every ISS
crew between Expedition 14 now on orbit through Expedition 19 in
2009 will have a licensed amateur radio operator aboard.

SuitSat-2 is currently under development.  Work continues as the
team awaits official approval by the various space agencies for
a planned deployment in February, 2008.  The SuitSat-2 project
includes these features:

 + Expanded education outreach with prepared lesson plans.

 + Software Defined Transponder capable of supporting SSB, CW,
   FM voice, SSTV, and CW IDer.  An uplink passband at approx-
   mately 145.9 MHz and downlink passband at approximately
   437.6 MHz is being proposed.

 + SSTV support for up to 4 cameras.

 + Solar panels in addition to battery power to support the
   radio payload plus additional sensors, and 4 experimental

Lou McFadin, W5DID demonstrated a prototype SuitSat-2 helmet
mounted antenna for 2M and 70cm.  He also showed the proven
safety interlock control box used by the astronauts to activate

Howard Long, G6LVB continued the ARISS discussion by showing the
new amateur radio equipment which will be included in ESA's
Columbus Laboratory module to be attached to the ISS in early
2008.  This will feature a linear transponder with L-band uplink
and S-band downlink.

The "Under the Wings" Banquet held in the Air Force Museum was con-
sidered a major success.  In addition to the meal on Friday evening
over 300 participants were able to also enjoy touring the museum
displays.  We received many enthusiastic compliments at the booth 
the next day for this joint AMSAT/TAPR event.

Watch for more details, including photos coming in the next AMSAT

OSCAR-11 Report 16 May 2007

AMSAT News Service Bulletin 140.04
May 20, 2007
BID: $ANS-140.04


OSCAR-11 might switch ON around 18/19 May and possibly 8/9 June.  
However, due to solar eclipses the satellite is likely to switch OFF, 
almost immediately, probably after less that one orbit.  This brief 
period of activity could occur when the satellite is over any part 
of the world.

Any reception reports would be grately appreciated. Please send to 
the address below or post to amsat-bb. 

Recently the satellite's 145.826 MHz beacon was heard from 22 to 28 
April. The beacon switched ON as expected. This short period was of 
special interest since the solar eclipses started on 21 April and 
steadily increased each day, reaching a duration of 12.6 minutes 
when the beacon switched OFF. Thus it was an rare oportunity to 
study the effect of solar eclipses on the satellite.

Good signals were heard on most passes, although they became weaker 
towards the end of the ON period. Good copy of the telemetry was 

Peter, ZL3TC reported hearing the satellite switch ON, after coming 
out of eclipse at 08:14 on 28 April.   These observations suggest 
that the satellite's electronics may be suffering from low power 
supplies, before the watchgog timer cycle finally resets.

Clive summarized, "I am indebted to Ian ZL1AOX, Peter ZL3TC, David 
G8OQW, Jeff KB2M, Edward BX1AD, Sil ZL2CIA, Dave G1OCN, John K8YSE 
and Grant VK4JAZ for their reports. Many thanks!"

The Beacon frequency is VHF 145.826 MHz with AFSK FM ASCII Telemetry

Listeners to OSCAR-11 may be interested in visiting Clive's website. 
If you need to know what OSCAR-11 should sound like, there is a short 
audio clip for you to hear. The website 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 captur-
ing data, and decoding ASCII telemetry.  The URL is:

+ A message received from the GO-32/Techsat Ground Control Station 
  said, "The debugging session for GO-32 is not over yet. We think 
  we will need 2 more weeks. During this time, BBS's services will 
  be suspended from time to time. Further more, in some cases the 
  BBS content will be lost without warning.  We apologize for the 
  inconvenience to all GO-32 BBS's users. We hope to return the 
  satellite to full operation soon."

+ Microwave Update 2007 is planned for October 18-19-20 in Historic 
  Valley Forge near Philadelphia, Pennsylvania.  This event will be
  hosted by the Pack Rats--Mt Airy VHF Radio Club. Full info and

1. Successful School Contacts 

On Wednesday, May 9, students attending Sunset Mesa Schools in 
Albuquerque, New Mexico participated in an ARISS contact. Nine 
students were able to ask one question each of astronaut Sunita 
Williams, KD5PLB.  The Sandoval County Amateur Radio Emergency 
Service (SCARES) assisted with the contact and gave a presentation 
on ham radio to the 400 students. Two local television stations 
covered the event. KOB, News Channel 4 ran an article on the contact. 
See: http://kob.com/article/stories/S81164.shtml?cat=515

Escola Secundária de Estarreja in Portugal experienced an ARISS 
contact on Wednesday, May 9. Sunita Williams, KD5PLB, answered 11 
questions put to her by seven students, all licensed ham operators, 
as approximately 200 students looked on.  The contact was covered 
by nationwide and local television stations, a newspaper and a 
radio station.

An ARISS contact was completed with Barrhaven Public School in Ottawa, 
Ontario on Tuesday, May 15. The school is forming a space club which 
is open to first through fifth graders. Through this club, students 
will learn about the Space Station via the internet and guest speakers. 
They will track the ISS and plot its course. They will learn how to 
speak on the radio and work on related art projects such as posters, 
banners and murals.  A contest will be held to create a mission patch 
which will be used on T shirts for the children. The media will be 
notified of the event. The audio for this event will be fed into the 
EchoLink AMSAT (101 377) and JK1ZRW (277 208) servers. 

Kenneth J. Carberry Intermediate School, a 2004 NASA Explorer School, 
located in Emmett, Idaho completed an ARISS contact on Wednesday, May 16. 
Students will research and create a Space Program timeline. They will 
research ISS astronauts and the countries involved with the Space 
Station, and determine the research being carried out onboard. They 
will also design posters to announce the upcoming event.

2. Upcoming School Contacts

Toyon Elementary School in San Jose, California, a 2004 NASA Explorer 
School, has been slated for an ARISS contact on Monday, May 21.  
Students will determine what experiments are being conducted on the 
ISS. They will research the astronauts and their backgrounds and 
write compositions based on their findings. A contest will be held 
to select questions which will be asked of the astronaut. A poster 
contest will be held and the posters will be displayed around town. 
Students and their families will be invited to the school’s Family 
Science Event which will feature guest speakers and hands on activities.
