SPACE FAIR PART 1 SUCCESSFUL
HR AMSAT NEWS SERVICE BULLETIN 109.01 FROM AMSAT HQ
SILVER SPRING, MD, April 19, 1998
TO ALL RADIO AMATEURS
BID: $ANS-109.01
Keith Pugh, W5IU, AMSAT-NA Vice President of Operations, tells ANS the
preliminary operations of Space Fair '98 at the Riverside Applied Learning
Center last week met with great success. W5IU reports the "introductory
talks with ninety young students was very rewarding, and following the
talks, communication demonstrations were performed on two AO-27 passes and
one Mir pass, with lots of interest from the kids." Riverside Applied
Learning Center is an elementary school for 'special kids' in the Fort
Worth, Texas area. The school has placed emphasis on learning about outer
space this year.
That evening, approximately 200 students and parents from the school
attended a 'Mir Visual Sighting Party' and were treated to a "perfect 60
degree elevation Mir pass," said W5IU. Keith reports the kids were told to
come in their pajamas so that they would be ready for bed when it was over.
"With the degree of enthusiasm the pass generated, I would venture that
they didn't go to sleep until much later," said Keith.
The second part the fair is scheduled for Friday, April 24th, at the
school. W5IU will be on the air live from the school operating through the
active analog satellites between 13:30 and 20:30 UTC. Keith also invites
digital operators to send messages to W5IU via AO-16, LO-19, UO-22, KO-23,
and KO-25. Messages from foreign stations will be especially interesting
for the students as they plan to display the message traffic live and plot
the location of each sender as the messages arrive.
Stay tuned to ANS for an update report on Space Fair '98.

MIREX SCHOOL DAY TEST
HR AMSAT NEWS SERVICE BULLETIN 109.02 FROM AMSAT HQ
SILVER SPRING, MD, April 19, 1998
TO ALL RADIO AMATEURS
BID: $ANS-109.02
According to MIREX President Dr. Dave Larsen, N6CO, the MIREX team has
authorized a special MIREX School Day test on April 27, 1998 between 10:00
and 23:00 UTC. The purpose of the test is to improve the understanding of
students about the Mir station and demonstrate the factors involved in
space communications using amateur radio. Of the many schools invited to
participate, even schools for the deaf and disabled will be able to
experience the event through their computer displays.
N6CO reports there is no limit to the number of stations that can
participate, since any amateur radio station at any school may monitor the
downlink of the test. All stations will be able to capture and log
communications from both Mir itself and schools authorized to transmit. Due
to the limited capacity on the uplink, however, the number of stations
authorized to transmit will be limited to under 100 per footprint area.
A special version of packet software called MIRMON has been donated by Bob
Bruninga, WB4APR, for unlimited use during this experiment. MIRMON will
capture all position reports, bulletins and messages and give schools a
consistent display of the event. The software may be downloaded along with
further test details and a replay of the last such experiment on the Naval
Academy/MIREX web page using the following URL:
http://web.usna.navy.mil/~bruninga/mirex.html
Schools with at least a 146 MHz, 25 watt FM radio, omni antenna and
conventional TNC should be successful. MIREX is asking individual amateurs
in North America desiring to participate to monitor the test in receive
only, or to visit a school and set up a demonstration station to qualify
for test transmit authorization. Due to the small number of foreign schools
that have indicated they will participate in the test, N6CO has indicated
that home stations outside of the USA are also welcome to participate in
the demonstration.
Schools without current ham radio equipment can monitor the event via the
Internet. The MIREX team is trying to find dedicated ground stations, (at
least one per continent), that can link their receiver to the MIREX growing
network. Currently, stations in the USA, Mexico and Spain under
construction.
For additional information on MIRMON or school data, contact Bob Bruninga,
WB4APR, at:

BID: $ANS-109.03
NASA has awarded Matthew Bordelon, KC5BTL, with its coveted Space Flight
Awareness Award for his leadership and technical contributions to the US
space program. The award, known as the Silver Snoopy, was presented to
KC5BTL recently at the Johnson Space Center.
Bordelon, who's the principal investigator for the Space Amateur Radio
Experiment, or SAREX, received the award from astronaut Don Thomas, KC5FVF.
The award letter cited Bordelon's "distinguished project leadership and
outstanding technical contributions to the highly critical space shuttle
orbiter upgrade effort." It also mentioned his efforts in training and
mission support for the SAREX program.
Bordelon said the award pin was flown on STS-63. The Space Flight Awareness
Award is given to less than 1% of NASA's civil servant and contract
workers. Recipients are nominated by NASA management.
AMSAT-NA VP Keith Baker, KB1SF, sends congratulations to KC5BTL from the
worldwide AMSAT community, noting that Matt is highly deserving of the
award, and adding, "way to go Matt!"

1.2 GHZ THREAT
HR AMSAT NEWS SERVICE BULLETIN 109.05 FROM AMSAT HQ
SILVER SPRING, MD, April 19, 1998
TO ALL RADIO AMATEURS
BID: $ANS-109.05
The ARRL has learned that the second civilian frequency for the global
positioning system (GPS) could wind up within Amateur Radio's secondary
allocation at 1.2 GHz. A decision on whether the new, second frequency will
be 1205 or 1250 MHz is expected to be made sometime in August. An
allocation at 1250 MHz could mean the end of amateur radio in the band 1240
to 1260 MHz. The Amateur Radio 23-cm band runs from 1240 to 1300 MHz.
In February 1997, the Department of Transportation (DOT) and the Department
of Defense (DOD) announced an agreement assuring civilian GPS users of a
second frequency considered essential for critical civilian GPS uses.
According to a DOD news release, the White House Commission on Aviation
Safety and Security, chaired by Vice President Al Gore, "called for the
establishment of a second civil frequency as part of a broader program to
maintain US leadership in aviation and satellite technology."
More information on the 1.2 GHz threat is available at the following URL:

In response to many requests for information about methods of decoding
OSCAR-11 signals, Clive, G3CWV, has added a package of information to his
web site. The site also contains some software
for capturing data and decoding ASCII telemetry and WOD. There is an
archive of raw data for analysis, which is continually being expanded, as
new data is captured. There are also some audio files, including a
Mode-S recording. The audio files are examples of each type of data
transmitted by OSCAR-11. The files should help listeners identify the
various types of data, and give an indication of the signal quality
required for successful decoding. The URL is:
http://www.users.zetnet.co.uk/clivew/
During the period of March 21st to April 15th excellent signals have once
again been received from the 145.826 MHz beacon.
The 435.025 MHz beacon is normally off. However it can sometimes be heard
when the satellite is being commanded by ground control. The data
transmitted is mainly binary.
The mode-S beacon is on, transmitting an unmodulated carrier, but telemetry
indicates that it has partially failed, delivering half output power. Three
reports of Mode-S reception have been received, from Mike, WL7BQM, Ed, K9EK
and Jim, KK3K.
Reception reports should be sent to:
