Jim Sanford, WB4GCS, Eagle Project Manager has authorized expenditure
of funds for purchase of components and construction of four proto-
types of the Eagle UHF receiver designed by John Stephenson, KD6OZH.
The boards will be distributed as follows:
+ One to Juan Rivera, WA6HTP, for acceptance testing followed by
limited vacuum and thermal testing.
+ One to be demonstrated at Dayton.
+ One to the SDX folks for their development.
+ One to be put through the ATP either by Jim, or wherever anyone
else wants to evaluate. This will then become available as needed
for demonstrations or SDX development.
Events leading to this decision:
+ Design by John and Peer review.
+ Development of ATP by Juan and peer review.
+ Assembly of a procurement, construction, and test team of Project
Oscar members under Juan's leadership.
+ PCBoard layout by John. Peer review of schematic to board correl-
ation in progress.
+ Development of costed Bill of Materials (BOM) by the Project Oscar
team. This was a LOT of work, and actually resulted in some tweaks
to the design and component selection.
+ Peer review of the BOM in progress.
To get an idea of the thoroughness that each module for the satellite
will undergo, look at Juan's action list on Eaglepedia:

The March 2007 issue of the RSGB magazine RadCom features a superb
article entitled "Getting Started on Amateur Radio Satellites" by
John Heath G7HIA. It is an excellent introduction to the exciting
world of Amateur Satellite Communications.
The Radio Society of Great Britain and the author have generously
agreed to allow AMSAT-UK to put the PDF of the article on the web
and it can be seen at http://www.uk.amsat.org/
Click on "How Do I Start" on the left hand side of the home page
then click on "Getting Started on Amateur Satellites (RSGB article)"

Ray Hoad, WA5QGD, AMSAT-NA Orbital Data Manager reported this week,
"I am pleased to announce that AMSAT's request to re-distribute AFSPC
Keplerian elements from Space-Track has been approved for another year.
Our USSTRATCOM Form 1 request to distribute the Keps was approved as
of April 5, 2007. Thanks to Mayor Matchett and his group. We are 'good
to go' for another year."
Clive, G3CWV, said, "OSCAR-11 switched ON early 01 April, as expected.
Good steady signals on the 145.826 MHz downlink. This is the last ten
day operational period before eclipses start on 20 April. The eclipses
continue until 23 August. If the satellite behaves as it did last year,
it is unlikely to be heard for any length of time, during the eclipse
period."
A press release by Charles Simonyi, KE7KDP, the next ISS Space Tourist
scheduled for launch on April 7 reported, "In further support of the
ARISS program, Dr. Simonyi additionally will perform maintenance on
various pieces of ham radio equipment on the ISS. This work will include
testing one radio set to isolate an antenna problem with the equipment
and reprogramming the default settings on a second unit to correct a
configuration problem." (via G0SFJ) The configuration problem is
thought
to be "one that can be reloaded from a computer via a serial
port on
the front of the radio, without disassembling anything. All
that is
needed is the computer, crew training, and scheduled crew time
to do
it. (via W8AAS)

1. ISB School Contact Successful
On Tuesday, March 27, students attending the International School
of Brussels (ISB) in Belgium participated in an ARISS contact via
the telebridge station NN1SS in Greenbelt. An audience of 200 students,
parents and teachers watched as sixteen students posed one question
each to Sunita Williams, KD5PLB. ARISS delegate Gaston Bertels, ON4WF,
gave a presentation on amateur radio and the ISS to the students who
showed much enthusiasm. At least two of the children asked numerous
questions on how to become an amateur radio operator.
ISB audio as well as pictures are available on:
http://www.ariss-eu.org/2007_03_27.htm
An ARISS contact was completed with St. Michael's Primary School in
Daceyville, New South Wales, Australia on Monday, April 2. Approximately
180 children in grades K-6 are enrolled at St. Michael's. National
television and newspaper coverage is expected.
Glenden State School in Glenden, Queensland, Australia completed an
ARISS contact on Wednesday, April 4, 2007. The school will incorporate
the
contact into the science, social studies, art and math curricula
for
students in Preschool - Grade12. All students will contribute to a
space
museum by designing space art, posters and travel brochures. They
may
also design a space station and robotics for a space vehicle or
write
letters to NASA concerning careers available in the space
industry.
Parents and the community will be invited to Space Week to
observe the
products of these activities. Nights of star gazing and
poetry contests
will also be held.
2. Upcoming School Contacts
Salt Creek Primary School in Salt Creek, Australia has been approved for
an Amateur Radio on the International Space Station (ARISS) contact on
Thursday, April 12 via the telebridge station W6SRJ in California, USA.
Salt Creek is a small rural school with an enrollment of twenty students
located 80 km north of Kingston in South Australia. The school serves
the sheep and cattle farmers in the area. Audio from this contact will
be fed into the EchoLink AMSAT (101 377) and JK1ZRW (277 208) servers,
as well as into the IRLP Discovery Reflector 9010.
3. Astronaut Training Status
On Tuesday, March 27, Paolo Nespoli received the basic ISS Ham school
contact training in preparation for anticipated school contacts to be
conducted while he is visiting the ISS during the STS-120 (10A) mission.
He was familiarized with both the Ericsson system located in the FGB
and the Kenwood system located in the Service Module. Nespoli will be
operating under his Italian amateur radio call IZ0JPA.
4. McArthur to Attend ARRL Expo 2007
The American Radio Relay League (ARRL) ran a web story covering Bill
McArthur's attendance at the ARRL Expo at the Dayton Hamvention 2007
which will be held May 18-20.
