AMSAT's External Relations Team Update
AMSAT News Service Bulletin 114.01
From AMSAT HQ SILVER SPRING, MD.

To All RADIO AMATEURS
BID: $ANS-114.01
AMSAT's External Relations Team handles AMSAT interactions with outside
groups such as government agencies, educational groups as well as other
amateur radio and AMSAT groups around the World. This Team has been
busy preparing for several upcoming events.
Work is continuing in support of the petition for reconsideration AMSAT
filed regarding orbital debris. Refining our positions as well as
resolving some highly divergent model predictions are some of the issues
being worked. No time line for action has been set by the FCC yet,
however AMSAT must be ready to respond promptly when asked.
Preparations are also underway for several upcoming conferences. The
Small Payload Ridesharing Conference will be held in Denver this year.
The focus of this conference is developing increased launch
opportunities for small satellites and secondary payloads. Another
upcoming event is the combined Cubesat workshop and Small Satellite
Conference in August. This year AMSAT will have a table in the
exhibitor area at the conference. Planning for materials, demos and
volunteers is now underway.
A final area that will be getting additional attention in upcoming
months is developing an "educational program" for AMSAT. Several ideas
have been proposed. Exactly how this will develop will depend greatly
on the passions brought to the program by those who volunteer. Anyone
interested in helping in this area is encouraged to contact Lee McLamb,
KU4OS, at ku4os@amsat.org

Meet Astronaut Tony England, W0ORE during Hamvention 2005
Friday May 20, 11:00 AM - noon, AMSAT booth
Friday May 20, 7:30 to 9:30 PM, AMSAT Banquet at the Amber Rose Restaurant
Here is your chance to meet Dr. Tony England, the second astronaut to use
ham radio in space!
Come by the AMSAT booth Friday morning for a terrestrial encounter.
In 1985, Tony first went into space onboard the space shuttle Challenger.
During his eight-day mission, he was a NASA Mission Specialist, responsible
for conducting many of the experiments in the onboard laboratory. The
mission included a ham radio payload called SAREX, the Shuttle Amateur Radio
Experiment.
AMSAT President Rick Hambly, W2GPS will also be available at the AMSAT booth
during Tony's Friday 11:00 am - noon visit.

FM operation on a linear transponder not good practice
The possibility of FM operation through the linear transponders on board
the soon-to-be-launched VUSAT was announced recently by AMSAT-India. The
Advisory Panel to the IARU Satellite Advisor, Hans van de Groenendaal,
ZS6AKV, considered this during its regular Echolink consultative meeting
last weekend. The group pointed out that FM is an inefficient use of
spectrum and power and recommended strongly that FM should not be used
on linear transponders. In many countries with large amateur
communities, FM on a linear transponder is a totally unacceptable mode
of operation and discouraged at all times.
The IARU Satellite Advisor and the Panel have suggested to AMSAT India
not to publish FM as a user option for the linear transponder, and to
discourage the use of FM through these transponders, especially in
countries with large amateur populations.
The IARU Satellite Advisor and his panel meet on Echolink on a regular
basis to review requests for frequency coordination. The main objective
is to advise satellite builders on spectrum use in order to achieve
harmonious use of the limited spectrum and to avoid or minimize
interference.
“We have carefully chosen our meeting time to enable team members in the
US, Europe and Australia to talk to each other at a reasonable time of
the dayö, ZS6AKV said. It is quite a challenge, when it is midday in the
USA it is late evening in Europe and Africa and very early the next
morning in Australia.
Over the past few years the team has developed a number of guideline
papers for satellite builders and operators. For more information visit

ARISS Status
April 18, 2005
1. New Hampshire School Contact Successful
On Wednesday, April 13, Maple Avenue Elementary School, in Goffstown,
New Hampshire, had a successful contact with Leroy Chiao, KE5BRW.
Students asked twenty questions in front of an audience of two hundred
students, teachers, parents, and six local dignitaries. Three newspapers
and a television documentary producer were in attendance to cover the event.
Echolink was also used for this contact. The audio transmission from a
webcast was fed into the AMSAT and EDU_NET servers. Twenty-one
connections were made, and stations from the U.K., U.S.A., Australia,
Holland, Slovakia, and Switzerland listened in.
2. California School Contact Successful
Fort Ross Elementary School is a small school with an enrollment of 50
students, located in Cazadero, California, a remote area ninety miles
north of San Francisco. On Friday, April 15, the children experienced a
successful contact with the ISS. The students were able to ask Leroy
Chiao, KE5BRW, 15 questions before the space station went over the
horizon. Approximately 85 people attended the event including a
reporter from the local weekly north coast newspaper, the Independent
Coast Observer.
3. Upcoming School Contacts
Schulhaus Feld 1 in Richterswil, Switzerland is slated for a contact
with Leroy Chiao on Tuesday, April 19, at 07:36 UTC. (Note the change in
date and time.)
Two ARISS contacts have been scheduled with ESA Italian astronaut
Roberto Vittori, as follows:
Istituto Tecnico Industriale Liceo scientifico Tecnologico “G.
Marconiö in Civitavecchia, Italy and Ist.Tecn.Comm.Einaudi-Mattei &
Ist.Statale Istr. Sup. Malignani In in Palmanova, Italy will share a
contact with the ISS, as they are linked via Skype (internet
telephony). The students from each institute will take turns asking
questions. The event is scheduled for April 18 at 08:45 UTC.
The European Space Research Institute (ESRIN), is slated for a
contact via telebridge station NN1SS on April 20 at 12:39 UTC.
4. ARRL Article on Flory Contact
On April 8, Flory Academy, a NASA Explorer School, spoke to the ISS via
amateur radio. ARRL covered the contact in an article entitled, “School
Community Cooperation, Student Activities Enhance Space QSO Experience.ö
See: http://www.arrl.org/news/stories/2005/04/13/2/?nc=1
