1. New York School Contact Successful
On Monday, May 16, students from Iroquois Middle School in Niskayuna, New
York spoke with John Phillips, KE5DRY, via the telebridge station, VK5ZAI,
in Australia, with the teleconferencing link donated by MCI. Paul Manning, a
seventh grader at the school, and nephew of Phillips, was among the twelve
students who asked 18 questions of the astronaut. The contact was broadcast
live by the in-school television station, WIRO. It was rebroadcast the
following day for the rest of the student body. In all, approximately 700
students, teachers, and visitors observed the event. John Phillips' brother
and sister-in-law attended, as did the television stations FOX23 and Time
Warner Channel 9. Both stations covered the event and ran stories on the
local news. The Spotlight, a local newspaper, followed up on Tuesday and
interviewed the students.
The audio for this event was available on the internet and fed through
Echolink and IRLP nodes. Echolink had seventy-eight connections, which
included 22 simplex and 12 repeater nodes and 2 conference servers.
Thailand, South Africa, Russia, Romania, and Italy were among the ten
countries listening in.
Twenty-one IRLP nodes were connected to the Discovery Reflector 9010.
Countries that participated included the USA, Canada, Norway, Germany,
England and Australia. One IRLP connection was made by Central Middle
School, an inner city school located in Victoria, British Columbia, Canada,
where twenty-four students and four teachers were amazed as they listened to
the ARISS question and answer session.
2. Upcoming School Contacts
Brigidine College in Sydney, New South Wales, Australia has been scheduled
for a contact on Thursday, June 2, at 09:30 UTC.
The audio will be fed through the Echolink AMSAT (101377) and EDU_NET
(77992) servers and IRLP Reflector 9010. It will also be available on the
internet. To join the event, go to:

4. ARISS International Teleconference Held
The monthly ARISS International Meeting was held on Tuesday, May 17. Agenda
items discussed included the ARISS face to face meeting in the U.K., to be
held August 1 & 2, third party traffic issues, the SuitSat Educational
Proposal, and the possibility of an ARISS contact with a school in Bejiing
during the 2008 Olympics.
5. SuitSat Educational Proposal
The SuitSat Educational Proposal was discussed and finalized during the
ARISS international teleconference. On Wednesday, May 18, the proposal was
released to the international delegates and to the NASA Education Office for
distribution to schools worldwide. It has also been posted on the ARISS
website at: http://www.rac.ca/ariss/suitsat.htm and to the AMSAT server at:

6. Dayton Hamvention 2005
The Dayton Hamvention 2005 was held this past weekend, May 20 - 22. AMSAT
and ARRL both had exhibition booths at the event, which draws crowds of
25,000 annually.
ARISS delegate Rosalie White, K1STO, gave a talk on ARISS at the Dayton ARRL
Expo, and accompanied inactive astronaut Tony England to the AMSAT dinner
where he gave a talk on space and youth.
ARISS Chairman Frank Bauer, KA3HDO, and ISS Ham Deputy Program Manager Mark
Steiner, K3MS, attended and gave a presentation entitled, "Human Spaceflight
Update: ARISS, the Moon and Mars."

7. Columbus Module
An Amateur Radio station will be located on the European Space Module,
Columbus. ARISS patch antennas, covering UHF, L-band, and S-band, will be
installed on the nadir of Columbus. ESA has agreed to cover the installation
cost of 100,000 euros. ARISS will need to pay 40,000 euros by mid June for
development and manufacturing costs, with another 40,000 euros due by year's
end. ARISS-Europe has extended a call for donations, and the progress can be
followed on the ARISS-Europe website.
See: www.ariss-eu.org/columbus.htm
8. Astronaut Training
On May 16, Kenneth Ransom of JSC provided ARISS training to astronaut Dan
Tani. He discussed school operations, packet capabilities, and cross band
repeater mode, as well as Field Day. Tani is tentatively scheduled to fly in
the spring of 2006 as a crew member of Expedition 13.
9. Field Day
Kenneth Ransom has invited Sergei Krikalev, U5MIR, and John Phillips,
KE5DRY, to participate in Field Day. This ARRL event is held annually the

Bangalore, India Students On Hamsat
AMSAT News Service Bulletin 149.02

BID: $ANS-149.02
On 17th May, International Telecommunications Day, the Little Lillys English
School, Bangalore during the Hamsat's 10:54 hours pass, spoke to other hams
in the country from their club station VU3LLE. A School made 18 element
arrow antenna was used for the ground station. Pics, sound and movie clips
are posted at www.amsatindia.com. I am sure such activities will pique the
young minds. Hamsat is really bringing space science right into the
classrooms.

OSCAR-11 Report - 25 May 2005
AMSAT News Service Bulletin 149.03

BID: $ANS-149.03
This report covers the period 18 April to 24 May 2005.
OSCAR-11 resumed transmissions on April 28, after its ten day period of
silence. The telemetry showed that ALL the analogue channels were zero,
although the status channels were normal.
The on-board clock was five hours slow.
Signals were fairly good, although at the present time, I cannot track the
satellite accurately owing to a stuck elevation rotator!
Good signals were also received on 30 April, with all the telemetry channels
showing zero values. The on-board clock was 4.45 hours slow.
Sometime between 30 April and 02 May the satellite switched OFF. This
coincided with the start of the solar eclipse season, which started on 27
April, reaching 10% of the orbit time by 02 May.
Nothing heard on 18 May when the satellite might have been expected to
resume transmissions. However, on 19 May Gustavo LW2DTZ (located near Buenos
Aries) reported hearing good signals at 22:11 UTC. Many thanks Gustavo for
that report.
It is possible that the satellite may still be controlled by the watchdog
timer, 10.3 days ON followed by 10.4 days OFF. Perhaps the eclipses may
cause the satellite to switch OFF early, after a day or two, when the
battery voltage is too low to operate the system.
If this theory is correct, the satellite might resume transmissions around
08 June, for a day or two. Commands from ground control could also affect
operation times.
The solar eclipses should reach maximum duration of 23% orbit time in
mid-June. The eclipses should finish in mid-August, when the satellite
enters a period of continuous sunlight for the remainder of the year.
Any reception reports would be appreciated. Please send to me direct
g3cwv@amsat.org, or post to post to AMSAT-BB.
The Beacon frequencies are -
VHF 145.826 MHz. AFSK FM ASCII Telemetry - Occasional operation?
UHF 435.025 MHz. OFF
S-band 2401.5 MHz. OFF

Listeners to OSCAR-11 may be interested in visiting my web site. This
contains an archive of telemetry data, including all the data received for
2005.
The web site contains details about using a soundcard for data capture, and
also details about using hardware demodulators. There is software for
capturing data, and decoding ASCII telemetry.
