As ANS editor, I would like to apologize for the lack of ANS bulletins over
the Memorial Day holiday and the recent delay in transmission of ANS

AMSAT NEWS SERVICE
ANS 157
ANS is a free, weekly, news and information service of AMSAT North
America, the Radio Amateur Satellite Corporation. ANS reports on the
activities of a worldwide group of Amateur Radio operators who share an
active interest in designing, building, launching and communicating
through analog and digital Amateur Radio satellites.
AMSAT-NA is pleased to announce that recent and future development
in amateur radio satellites will be presented in San Diego, California
--October 8-11, 1999-- at the 17th Space Symposium and
AMSAT-NA Annual Meeting. More information is available from
Symposium chair, Duane Naugle, KO6BT, at:

This ANS bulletin set is dedicated to communications and FM pioneer
Frank Gunther, W2ALS, of Staten Island, New York, who died May 31st
at age 91. Gunther was in the vanguard of shortwave, two-way and FM
radio system development for military and public service applications.

SATELLITE PIONEER K2ZRO TO BE HONORED
AMSAT NEWS SERVICE BULLETIN 157.01 FROM AMSAT HQ
SILVER SPRING, MD, JUNE 06, 1999
TO ALL RADIO AMATEURS
BID: $ANS-157.01
The Kopernik Observatory located near Binghamton, New York
celebrated the observatory's 25th anniversary over the weekend with a
special event amateur radio station that also honored the memory of one
of the observatory's founders - Kaz Deskur, K2ZRO.
Kaz Deskur died in 1984. Deskur's widow and family attended as
honored guests along with keynote speaker Dr Joseph Dervay, a NASA
astronaut-physician.
Amateur Radio club station KB2UYF is located at the observatory, and
paperwork has been submitted to the FCC to change the station's call
sign to K2ZRO.
Deskur was a satellite pioneer who operated the observatory's ham
station under his call sign for many years. In the early days of the
OSCAR and AMSAT programs, K2ZRO was a familiar call sign on many
satellites. Kaz designed the original OSCAR-LOCATOR, a device many
'old-timers' used to track a satellite before the advent of personal
computers and software tracking programs. For many years AMSAT
sponsored an engineering award in Kaz Deskur's honor.
The Kopernik Observatory is establishing a special 'Wall of Honor for
Amateur Radio Satellites' to honor Kaz Deskur. All hams that knew or
worked with him are invited to send their QSL cards for display on this
wall. QSL cards may be sent (in an envelope) to:
Kopernik Space & Science Education Center
30 Front Street
Binghamton, New York
13905
Hams at Kopernik also will be active on June 19th, hoping to make many
contacts during the ARRL's Kid's Day event - with operation planned
on several satellites including FO-20 and AO-27.

1999 DIGITAL COMMUNICATIONS CONFERENCE
AMSAT NEWS SERVICE BULLETIN 157.02 FROM AMSAT HQ
SILVER SPRING, MD, JUNE 06, 1999
TO ALL RADIO AMATEURS
BID: $ANS-157.02
Many digital satellite operators will be on hand in Phoenix, Arizona this
September for the 18th annual ARRL and TAPR Digital
Communications Conference.
TAPR's Greg Jones, WD5IVD, will chair this year's conference.
The conference is an international forum for radio amateurs in digital
communications (including via satellite), networking and related
technologies - to meet, publish their work and present new ideas and
techniques for discussion.
Conference highlights include a full day of papers, breakout sessions
and selected topics for the beginner to advanced amateur digital
enthusiast.
Symposiums will include the latest in APRS information moderated by
Steve Dimse, K4HG, and featuring satellite regular Bob Bruninga,
WB4APR. The Saturday banquet will feature Geoff Baehr, N6LXZ, Sun
Microsystems chief network officer as guest speaker.

SAREX MISSION NEARS
AMSAT NEWS SERVICE BULLETIN 157.03 FROM AMSAT HQ
SILVER SPRING, MD, JUNE 06, 1999
TO ALL RADIO AMATEURS
BID: $ANS-157.03
As the International Space Station mission of STS-96 draws to a
very successful close, thoughts now turn to the next SAREX mission,
STS-93. This mission is tentatively set for a late July launch and is
scheduled to include both voice and packet operations.
AMSAT Vice President for Human Spaceflight, Frank Bauer, KA3HDO,
tells ANS that currently the International ARISS team is busy with the
development and qualification of hardware for ISS. The team will be
delivering the first ham equipment (the Initial Station) to NASA this July
for launch on STS-101 in December.
Initial Station hardware is being built and qualified by a multinational
team with members from Russia, Italy, Germany and the United States.
KA3HDO tells ANS that he is "quite proud of the international
cooperation that is occurring to bring all this hardware to flight status."
Meanwhile, ARISS team member Will Marchant, KC6ROL, reports
that five schools are currently scheduled to have dedicated contacts with
the crew of STS-93. Crewmembers are also expected to support random
voice contacts and packet operations on 144 MHz.

BID: $ANS-157.04
ANS news in brief this week includes the following:
** With the May/June issue of the AMSAT-NA Journal due to arrive very
soon, plans are underway for the July/August issue. Featured articles will
include an ARISS Update, A Chat with Andy Thomas, Don't Fear the
LEO's and an OPAL, PanSAT, StenSAT and VoxSAT overview. ANS
reminds satellite operators that AMSAT-NA membership includes the
Journal. -ANS/Russ, K5NRK
** A formal copy of the AMSAT Phase-3D Dayton Hamvention news
release has been placed in the 'News Release' area of the AMSAT-NA
web page. Check it out! -Paul, KB5MU
** Several news agencies have reported that Mir's current crew will
abandon the Russian space station in August, and the orbiter will circle
Earth unmanned until early next year. It is then expected the aging
station will burn up in the atmosphere. Repeated attempts to raise
money to continue support have failed. -AP/CNN/Morrock News
** When John Glenn returned from his historic shuttle flight last
November, it took him four days to regain his balance. But the fact he did
was one of the first concrete results to emerge from the mission. Using
knowledge gained from Glenn's mission and an extensive study of how
other NASA astronauts recover their sense of balance, researchers hope
to develop techniques to predict and prevent falls among elderly men
and women. -Florida Today
** Investigators using the Mars Global Surveyor spacecraft revealed a
new and complete look at the surface of Mars recently as they showed
off the most detailed elevation map yet made of the red planet. Over 27
million elevation measurements were assembled to produce the global
view. -Sky & Telescope

payloads, digital store-and-forward communications and mode L/S
transponders.
G7UPN reports that due to the increase in satellite temperature over the
past several days the 437.025 MHz 38k4 downlink is off again. "This
transmitter is generating too much heat now that the satellite is in
