AMSAT's Board of Directors met on 5 October in San Francisco, CA and
approved the following Eagle communications payloads:

+ A SSB/CW (etc.) transponder with uplink on U-band and downlink on
  V-band.  System design has a goal that it be usable over 75% of
  the orbit by an AO-13 or AO-40 capable ground station.

+ A SSB/CW (etc.) transponder with uplink on L-band and downlink
  on S1-band (2.4 Ghz).  An AO-13 or AO-40 capable ground station
  will be able to use this payload.

+ A low rate text message system, like SMS.  It will operate on
  U/V-bands and be usable over 75% of the orbit by a small terminal
  on the ground.

+ These transponders will be implemented using Software Defined
  Transponders (SDX).

Eagle will also carry an advanced communications payload (ACP).  Using
advanced signal processing and RF techniques, the ACP will allow:

1) Voice communications on S2-band (3.4 Ghz) uplink and C-band (5.8 Ghz)
   downlink using a single 60cm dish.  The satellite antennas will be
   electrically steered to reduce spin modulation and allow use over 75%
   of the orbit.

2) An additional, fix-pointed, uplink will be available at L-band.
   This L-band uplink will require a separate uplink antenna at the
   ground station.

3) High rate data communications, such as streaming video, using a 2m
   dish on S2/C bands.

4) AMSAT will develop and make available an affordable ground segment
   for the ACP SYSTEM.

Additional information will be posted on amsat.org in the near future.

ARISS, the Amateur Radio on the International Space Station program,
an amateur radio project sponsored in North America by the ARRL, AMSAT,
and NASA reported on the outcome of planning meetings held recently.

Sponsorship of the ARISS program is moving from NASA Headquarters to
Johnson Spaceflight Center (JSC) in Houston.  ARISS International Chair
Frank Bauer, KA3HDO, ARISS International Secretary-Treasurer Rosalie White,
K1STO, Deputy Chair, Mark Steiner, K3MS, and NASA ISS Ham Radio Project
Engineer Kenneth Ransom, N5VHO recently held planning sessions with various
JSC offices.

One future goal which will capture the imagination of many includes the
exploration of an ARISS role in the "Moon, Mars and Beyond" initiative.
They cited Amateur Radio's potential as a valuable tool to people living
on the moon for several months at a time.

Amateur radio will continue to be available on the ISS.  In addition to
the exploration initiatives just beginning construction projects will
continue to take place on the Space Station.  While NASA foresees busy
work schedules for the astronaut construction crews they also note that
more astronauts will be available to get on the air.

BID: $ANS-281.04

Since being recovered due to sufficient sunlight on its solar panels
PCSAT-1 should remain NORMAL OPS for the next few weeks until it exper-
iences an overload and resets.  Then we lose it till December.  The US
Naval Academy Satellite Laboratory team requests that amateur radio
users please adhere to these fundamental principles:

1) No unattended operations
2) No connections to or through PCSAT-1
3) UI digipeating and APRS packets only typically at 1 minute rates or so
4) Watch pcsat.aprs.org for live activity
5) Use the path of VIA PCSAT-1 or VIA ARISS
6) Minimize all packets after dark!

PCSAT-1 acts just like any terrestrial APRS digipeater.  It willrespond
to all of the existing and legacy paths that are used on APRS. They are:
 RELAY
 WIDE
 WIDEn-N
 TRACEn-N
 and ARISS

If people want to keep track of their success on FINDU.COM, see:
http://pcasat.aprs.org then they should not use a n-N path and should
change their SSID so that their station call is unique for this space
application.  Otherwise, as soon as they use the same station again on
terrestrial APRS, then the posit via the satellite will be overwritten.

Recent packets digipeated via PCSAT can also be viewed on-line at the
PCSAT url mentioned above.  The web site also includes a map showing
the reported positions of stations digipeating APRS packets via PCSAT.

Enjoy PCSAT-1 and APRS! Make contacts, QSO, enjoy!

NASA is calling on college undergraduates interested in performing
reduced gravity experiments onboard the agency's "Weightless Wonder"
aircraft to submit their proposals by Monday, Oct. 30.

Each proposal will be evaluated for technical merit, safety and an
outreach plan. The selected proposals will be announced Dec. 11 and
flown in 2007. Selected teams may also invite a full-time, accredited
journalist to participate with them to document the experience.

The Reduced Gravity Student Flight Opportunities Program at NASA's
Johnson Space Center, Houston, has given undergraduate teams the chance
to research, design, fabricate, fly and evaluate reduced gravity experi-
ments annually since 1995. This will be the first time students can
design their experiment for lunar gravity, which is one-sixth of Earth's.

NASA's modified McDonnell Douglas DC-9 jet aircraft will give flyers
the feel of space, as it performs a series of steep climbs and freefalls
over the Gulf of Mexico, creating multiple periods of reduced gravity.
Each parabolic maneuver produces about 25 seconds of weightlessness, and
by changing its flight path, the jet can produce periods of lunar gravity.

Square Mile Array Heading for Quiet RF Environment in Southern Hemisphere

Australia and Southern Africa have been short-listed as the countries
to host the Square Kilometre Array (SKA), a giant next-generation radio
telescope being developed by scientists in 17 countries.

The SKA will be a set of thousands of antennas, not a single giant
instrument, spread over 3000 kilometres, but with half of the antennas
located in a central region 5 kilometres across. The SKA will be 50
times more sensitive than the most powerful radio telescopes we now
have. It will peer deep into the cosmos to pick up signs of the first
stars and galaxies to form after the Big Bang.  If there are extra-
terrestrial intelligences out there in the Milky Way with airport or
ionospheric radars, the SKA will detect them.

For Australia, the core site is proposed to be at Mileura station,
about 100 km west of Meekathara in Western Australia. Other dishes
would be distributed over the Australian continent with the possibility
of extension into New Zealand. In Southern Africa, the central location
would be at the Karoo site in the Northern Cape region of South Africa,
about 95 km from Carnarvon, with further dishes located in South Africa
itself and in neighbouring African countries.

A key requirement of the core site is that there must be a very low level
of man-made radio signals, because interference will mask the faint cosmic
radio waves the telescope is designed to detect. South Africa and Australia
are both making excellent progress towards protecting these unique environ-
ments with radio-quiet zones that will limit the use of radio transmitting
equipment.

Further analysis of the short-listed sites will now be carried out, with
the final decision on which of the two sites will host the SKA expected
towards the end of the decade.

1. Swiss School Contact Update

On Friday, September 22, Thomas Reiter, DF4TR, spoke with students
from the Gymnase Intercantonal de la Broye in Payerne, Switzerland.
The students gathered at the Musee de l'aviation militaire, the Swiss
Air Force Museum. This was a highly publicized event and was attended
by many VIPs including representatives from education, ESA and the
Swiss Astronautics Society as well as Swiss astronaut Claude Nicollier,
HB9CN.  It received extensive media coverage from numerous newspapers,
television stations (Nord Vaudois, Suisse Romande) and radio stations
(Fribourg). The video was streamed over schoolnet.ch/ariss. It is esti-
mated that approximately 650,000 heard of the contact via the radio
and television broadcasts.  For more details on the contact, go to:
http://www.ariss-eu.org/2006_09_27.htm

2. Upcoming School Contacts

The ARISS team continues to work on scheduling the Expedition 14
school contacts.

3. ARRL Article on Three ARISS Contacts

ARRL wrote an article covering the three contacts made from the ISS on
September 22. “Civilian Space Traveler, Astronauts Pull Off ARISS Ham
Radio Triple Header” may be found at:
http://www.arrl.org/news/stories/2006/09/27/101/?nc=1

4. School Teacher Makes General Contacts with ISS

A teacher (callsign N8MS) from Coloma Junior High School, located in
Southwest Michigan, had an unscheduled contact with the International
Space Station on Tuesday March 21, 2006 when Bill McArthur answered
12 of his students’ questions. His class was also able to contact
Anousheh Ansari during her stay on the ISS and have her answer a
few questions. The audio from his most recent contact may be heard on
Anousheh’s space blog,
http://spaceblog.xprize.org/2006/09/28/n8ms-ham-radio-contact/

5. Arizona Class Listens to Space Participant on Radio

A teacher from Pueblo Magnet School in Tucson, Arizona wrote to say
that he and his students listened to space participant Anousheh Ansari
with a very simple radio station, and could hear her for a short while,
although they did not connect.  He felt this opportunity of hearing
someone on the Space Station motivated his students and that it was a
very good lesson for them in tracking space vehicles. 
 
6. ARRL Article on Expedition 13

ARRL posted a short story covering Expedition 13 crew members returning
to Earth. See: http://www.arrl.org/?artid=6830
