AMSAT NEWS SERVICE
ANS 248
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:
ko6bt@amsat.org (or) the AMSAT web site.

This ANS bulletin set is dedicated to the memory of Robert Funck,
KB5GQ. Bob had an abiding interest in VHF, was involved in repeater
coordination and served as a long-time representative to the Louisiana
Council of Amateur Radio Clubs, the frequency-coordination entity in
Louisiana. Funck was instrumental in developing the Amateur Radio
exhibit for the Louisiana World's Fair in 1984. Services were August
10th.

BID: $ANS-248.01
AMSAT-NA, the Radio Amateur Satellite Corporation, is sponsoring a
free Amateur Radio satellite workshop for colleges and universities. The
workshop will be held on Thursday, October 7, 1999, just a day before
the official opening of the 17th Space Symposium and AMSAT-NA
Annual Meeting.
The Workshop will provide a series of educational lectures to
participants interested in using the Amateur Radio Satellite Service in
their classroom and small satellite projects.
Scheduled Workshop topics will include:
* Amateur Radio satellites, who, what, where and when
* the role of Amateur Radio and the Amateur Radio Satellite Service
* ITU and FCC rules and regulations
* spectrum assignment and frequency coordination
* Amateur Radio in the classroom or laboratory
* an open forum for questions and comments
There is no fee to attend the workshop.
More information on the event is available from AMSAT-NA's
Educational Liaison, Steve Bible, N7HPR. Contact Steve by e-mail at:

Jeff Garrett, ZL1BIV and Ian Ashley, ZL1AOX, have recently released a
satellite compendium (on CD-ROM) --that is packed with information on
Amateur Radio satellites-- for use by beginners and experts alike. The
compendium is organized into 23 folders containing 858 files on topics
that include:
* images from the Phase 3D Laboratory
* Internet web sites for Amateur Radio satellite information
* past Amateur Radio satellite bulletins
* satellite telemetry files
* satellite tracking freeware
* sound card utilities
* technical articles on satellite topics
AMSAT-ZL has allowed its North American counterpart to make this
information available to satellite operators via distribution by the
AMSAT-NA office for a suggested donation. Proceeds from this project
will go to support satellite programs currently underway by AMSAT.

ANS news in brief this week includes the following:
** Space Port Nevada is ready for business. From Las Vegas,
SpaceDaily is reporting that it's "all systems go" to make the Nevada test
site America's newest threshold to space. More details can be found
at: http://www.spacedaily.com/spacecast/news/rlv-99r.html. -SpaceDaily
** Happy birthday to the Internet, unofficially celebrating its 30th birthday
this month. -ANS
** AMSAT's Martha Saragovitz reminds everyone that time is running out
to pre-register for the AMSAT Space Symposium and Annual Meeting.
The AMSAT office will be closed the week of September 27th. The last
day Martha can accept registration is September 23rd; after that date
registration will be accepted at the door only. Call Martha at
301-589-6062 for more information. The AMSAT office is also
closed on Monday, September 6th, Labor Day. -ANS
** Interested in working OSCAR Zero? Lance, W7GJ, has updated his
web site due to recent interest in getting on 2-meter EME. Changes
include simple antennas, updated tips on succeeding at EME and a
special page with suggestions for a small EME station (with equipment
that most satellite stations already have). The web site to begin finding
this information is http://missoula.bigsky.net/cri/w7gj. -MoonNet
** According to several news reports the first commercial SeaLaunch
is expected to soar into the sky by the end of September. The launch
vehicle is scheduled to carry a DirecTV satellite into orbit. -- SpaceDaily
** November's Leonid meteor shower will produce good displays this
year and next and strong storms of meteors in 2001 and 2002, that's
according to new research by Dr. David Asher, of Armagh Observatory
and Dr. Rob McNaught of the Australian National University. This is
good news for those satellite operators that also take part in
meteor-scatter communications. -ANS
** Residents of Monahans, Texas will forever remember March 22, 1998
as the day that a couple of meteorites plunked onto their town from the
sky. Their find eventually netted $23,000 when sold during an Internet
auction. The smaller piece made its way to the laboratories of NASA's
Johnson Space Center, whose scientists found something amazing
inside it -- liquid water. -Sky & Telescope
** Space Shuttle managers have reviewed the progress of electrical
wiring inspections and repairs on Endeavour and Discovery. Although
the work is progressing well, evaluations of the findings thus far are
continuing and managers have expanded the inspections based on
those findings. The time required to complete the work is still being
assessed. Managers do not plan to discuss target launch dates for
upcoming missions (including the International Space Station) until
more of the work has been completed, however it is anticipated that
no mission could technically be ready for launch before mid-October
at the earliest. -NASA
** Paul, KH6HME, reports working Clint Walker, W1LP/mm on 144 MHz
SSB to claim a new world distance record of 2954 miles. Signals
reportedly peaked S1. An unsuccessful attempt was made on 432 MHz.
-ARRL and NLRS
** ESA's new gamma-ray observatory, Integral, has passed an important
milestone in its development. The engineering model tests, which lasted
more than a year and which were to verify that all satellite subsystems
and instruments interface and function as a system, were successfully
completed recently. --SpaceDaily

MIR SPACE STATION
Ham radio activity aboard the Mir space station came to a close on
August 28, 1999 as the crew returned to Earth, leaving the station
unmanned. Mir is in a stable orbit with only essential systems running.
All Amateur Radio activities have ceased. Currently, the station is being
prepared for re-entry sometime in the first quarter of 2000, however, the
final fate of the space station has not been formally announced. Stay
tuned to ANS for further developments.
Current Amateur Radio equipment aboard Mir includes:
MIR SAFEX II 70-cm Repeater
Uplink 435.750 MHz FM w/subaudible tone 141.3 Hz
Downlink 437.950 MHz FM

DOVE stopped transmitting in March 1998. The 145.825 MHz and
2401.220 MHz downlinks are off the air and the satellite has not
responded to ground station control. No additional information is
available at this time.
WEBERSAT WO-18

Unknown status. ANS has not received any recent updates concerning
the current status of GO-32.
The TechSat-1B micro-satellite was successfully launched from the
Russian Baikonur Cosmodrome on July 10, 1998.
Last reported, the satellite does not have a continuos beacon, but does
transmit a 9600-baud burst every 30 seconds (for a continuous 3
seconds in length), on 435.225 MHz.
The TechSat team has constructed a home page about TechSat.

The satellite is not currently available for uplink transmissions and
recovery efforts have been unsuccessful over the past year.
Mineo, JE9PEL, reports he has again received minimal telemetry from
the satellite recently, dated August 30, 31 and September 1st.
SedSat-1, signifying Students for the Exploration and Development of
Space Satellite number one, was successfully launched and placed in
orbit on Saturday, October 24, 1998.

KITSAT KO-23
Uplink 145.900 MHz FM 9600 baud FSK
Downlink 435.175 MHz FM
Not operational. The downlink transmitter has not been operational for
any normal communication for several months.
ANS has learned (from HL0ENJ) that satellite downlink telemetry shows
two (or more) of KO-23's battery cells to be very unstable. Ground
control stations are operating KO-23 with only minimum systems.
Attitude control has been lost and power failures are being experienced
every two months. Control stations will try to verify current power status
during September and decide if recovery is possible.
