TASK FORCE FOR FUTURE TECHNOLOGY
AMSAT NEWS SERVICE BULLETIN 255.01 FROM AMSAT HQ
SILVER SPRING, MD, SEPTEMBER 12, 1999
TO ALL RADIO AMATEURS
BID: $ANS-255.01
AMSAT-NA President Keith Baker, KB1SF, has been asked to be a
member of a working group to explore the future of Amateur Radio
technology. Under direction of the American Radio Relay League, the
working group along with a technology task force will explore ideas and
proposals for new technologies to carry Amateur Radio into the next
century. "It is a great honor for me to represent AMSAT-NA on
this group," said KB1SF, adding, "I am looking forward to becoming
an integral part of a forward-looking team that's now helping to chart
the future of our great hobby." Also appointed to the working group is
long-time ANS contributor Rich Moseson, W2VU.
The ARRL Board of Directors created the Task Force and the companion
Technology Working Group last January, and ARRL President Rod
Stafford, W6ROD, has appointed a number of leading amateurs to serve
on both panels. The Task Force and the Working Group will work hand-
in-hand to identify, evaluate, and promote the most promising 21st
Century technologies for Amateur Radio.
Chairing the Task Force is ARRL First Vice President Steve
Mendelsohn, W2ML. ARRL Laboratory Supervisor Ed Hare, W1RFI, will
serve as ARRL HQ staff liaison to both committees.
The Task Force invites information and concepts on a wide range of
technologies with the potential to improve Amateur Radio and welcomes
the submission of ideas and proposals from all parts of the amateur
community. The information gathered will be used to help formulate
League policy recommendations on a wide range of technical issues.
Amateurs are welcome to submit ideas using the form on ARRLWeb at:
http://www.arrl.org/news/ttf/ (or)
via e-mail to: ttfinput@arrl.org
Suggestions are requested by November 30, 1999.
[ANS congratulates KB1SF and W2VU and thanks the ARRL for this

AMSAT NEWS SERVICE BULLETIN 255.02 FROM AMSAT HQ
SILVER SPRING, MD, SEPTEMBER 12, 1999
TO ALL RADIO AMATEURS
BID: $ANS-255.02
The International Space Station's systems continue to function normally
this week with no major problems.
Troubleshooting has continued on one of the Space Station's six
batteries. This battery is scheduled to be replaced and may be returned
to Earth for examination. Flight control teams in Houston and Moscow
continue to analyze data related to electronics associated with the
battery.
A pump test scheduled for next week will transfer nitrogen through
portions of the Station's propellant system. The test is designed to
monitor the electrical system as it supports the pump and to check the
function of the pump itself. In late October the pump is to be used to
transfer propellant among the tanks aboard the Space Station and
prepare it for subsequent docking with the Russian-built Service Module.
The Service Module will be the third element of the Space Station and is
now scheduled for launch from the Baikonur Cosmodrome in November.
The Space Station is oriented with Unity pointed toward Earth and Zarya
pointed toward space in a slow spin to conserve fuel and maintain an
even temperature for both modules.
The Space Station is in an orbit with a high point of 244 statute miles and
a low point of 234 statute miles, circling the Earth every 92 minutes. The
complex has completed more than 4,550 orbits since launch of Zarya
last November.
Space Station viewing opportunities worldwide are available on the
Internet at:

ANS IN BRIEF
HR AMSAT NEWS SERVICE BULLETIN 255.04 FROM AMSAT HQ
SILVER SPRING, MD, SEPTEMBER 12, 1999
TO ALL RADIO AMATEURS
BID: $ANS-255.04
ANS news in brief this week includes the following:
** Current CQ-VHF Editor Richard Moseson, W2VU, (and frequent ANS
contributor) has taken on additional duties as the new editor of CQ
magazine. Dick Ross, K2MGA, announced Moseson's appointment six
weeks after the death of long-time CQ Editor K2EEK. Rich has been
involved in numerous projects, including creation of CQ's Amateur Radio
videotape series, management of CQ's 50th anniversary issue,
development of the magazine's various Web sites, and most recently the
launch of CQ VHF. Congratulations W2VU from AMSAT! -ANS, ARRL
** The FCC has relaxed rules governing the use of spread spectrum
techniques by radio amateurs and opened the door to the possibility of
international spread spectrum communication. Once the new rules
become effective (November 1st), hams will be able to use techniques
other than frequency hopping and direct sequence spreading. In
addition, the new FCC rules will permit U.S. hams to use spread
spectrum techniques to communicate with amateurs in other countries
that permit SS. This announcement may help to open operation on
PanSat/PO-34. -ARRL, ANS
** The University of Texas Amateur Radio Club recently became one of
the few college or university radio clubs to have equipment for 1.2 GHz,
with the equipment intended for weak signal terrestrial work. Check out
the project online at: http://n5xu.ae.utexas.edu/images/1296/.
-Ken, KM5FA
** Kennedy Space Center is offering educators and members of
industry the opportunity to learn more about emerging technologies at
the nation's spaceport through an educational conference to be held in
early October. The 2nd Annual Partners in Education and Research
Conference is designed to inform participants and help NASA identify
research experts for future partnerships. -NASA
** Sweden has cut its code requirement and number of license classes,
reducing code speed from 12 to 5 words-per-minute and dropping the
number of license classes from 4 to 2. The Class 1 license offers all
Swedish amateur privileges and requires the 5-wpm test, while the
Class 2 ticket is a no-code license for VHF and UHF only. -ARRL
** In a new set of observations astrophysicists have discovered that
an afterglow can start in gamma rays during a gamma-ray burst,
thus suggesting that more than one activity is causing what appears
to be a chaotic explosion. Gamma-ray bursts are one of the most
mysterious events in the heavens. Their cause remains unknown,
although recent observations have allowed scientists to start narrowing
the possibilities. NASA has more information at the following URL:
http://science.nasa.gov/newhome/headlines/ast10sep99_1.htm -NASA
** Images of the earthquake-struck regions of Turkey are being provided
by European ERS satellites and SPOT satellites of the French national
space agency CNES. The data provided by the satellite systems is being
analyzed at ESA's research institute located in Frascati, Italy. Information
about the extent of the affected areas and about the effects of the
catastrophe on the ground will give valuable information to public
authorities and organizations working to repair the damage. The satellite
system operators are making the latest data available directly to potential
users. ESA and CNES have pledged to pool their satellite-based
resources and provide timely, pertinent information on parts of the Earth
struck by natural or man-made disasters. --ESA
** An inexpensive satellite-based e-mail service for people in remote
areas of the world and for captains of small boats has been launched by
the European Space Agency. ESA said that the Intercontinental Retrieval
of Information (IRI) satellite system, has now been activated and will
allow e-mail messages to be sent from anywhere in the world using a
satellite modem connected to a PC. Messages can be sent to or from
Internet users, or between remote users of the system. -TechWeb
** Some doorstep astronomy from ANS: In the U.S. look northwest just
as twilight ends to spot the Big Dipper. Its handle curves leftward more
or less in the direction of bright Arcturus, the brightest star shining in
the west. The front two stars of the Dipper's bowl point upper right
toward rather dim Polaris, the North Star (due north). -Sky & Telescope
