AMSAT NEWS SERVICE
ANS 247
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 Portland, Maine
- October 27-29, 2000 - at the 18th Space Symposium and
AMSAT-NA Annual Meeting. The Symposium Chairman is
George Caswell Sr., W1ME.
The 2000 Symposium will include once top-secret details about
intelligence gathering methods used during the early years of the Cold
War. The Saturday banquet speaker will be Cargill Hall, chief historian
of the National Reconnaissance Office. He will discuss (for the first time
in public) overhead reconnaissance along with a history of CIA-NRO
activities.

ATLANTIS CLEARED FOR ISS FLIGHT
AMSAT NEWS SERVICE BULLETIN 247.01 FROM AMSAT HQ
SILVER SPRING, MD, SEPTEMBER 03, 2000
TO ALL RADIO AMATEURS
BID: $ANS-247.01
NASA has informed ANS this it has cleared the space shuttle Atlantis for
its upcoming launch to the International Space Station. The launch is set
for September 8th.
The flight should last just short of two weeks during which time the
seven member crew will unload space station supplies from both the
shuttle and a Russian Progress cargo ship. The progress supply ship is
currently docked to ISS.
NASA also reported that the spacesuits the Atlantis crew will use during
this mission are completely safe. Earlier this summer several spacesuits
were found to be contaminated with potentially flammable oil. NASA
engineers cleaned oily regulators in the emergency oxygen packs of
several suits and then checked the operation of its entire spacesuit
inventory. All the suits passed.
The suits, which cost $12 million each, should not be confused with the
orange spacesuits astronauts wear at launches and landings. NASA
needs all 12 'spacewalking' suits to complete construction of the space
station, with at least 20 spacewalks planned during the next 18 months.
The space agency will have under three minutes to launch Atlantis
on September 8th rather than the usual five to 10 minute window for
a space station linkup -- the shortest launch window ever for a shuttle.
NASA is attempting to trim the launch windows, thus using the least
amount of fuel to reach the station.
Amateur Radio operators worldwide are looking forward to the
successful launch of Atlantis as it puts ham radio operation aboard
the International Space Station one step closer. This Atlantis mission
will not feature Amateur Radio operation from the shuttle or ISS, but
ham radio is an important part of the mission as the Atlantis crew
is scheduled to deliver ARISS hardware. Initial equipment will include
2-meter and 70cm handheld radios, a TNC, a specially developed
headset and signal adapter module along with specially developed
power adapters and the interconnecting cabling.
This mission marks the 4th Shuttle flight to the International Space
Station and the 3rd Shuttle mission this year. Stay tuned to ANS for
further updates.

ANS reminds satellite operators that 'Microwave Update 2000' --the
mid-Atlantic States' VHF Conference-- will be held soon. The conference
dates are September 28-30, 2000. The Mount Airy VHF Radio Club will
serve as hosts.
Microwave Update will include the traditional surplus tour and
evening flea markets, along with noise figure testing and an equipment
tune-up clinic.
Presentations are scheduled by Al Ward, W5LUA, Dave Olean, K1WHS,
and Steve Kostro, N2CEI. Activities will also be available for
non-amateur family members.

ANS IN BRIEF
HR AMSAT NEWS SERVICE BULLETIN 247.03 FROM AMSAT HQ
SILVER SPRING, MD, SEPTEMBER 03, 2000
TO ALL RADIO AMATEURS
BID: $ANS-247.03
ANS news in brief this week includes the following:
** Russia has pledged to send eight spacecraft, both manned and
unmanned, to the International Space Station in 2001, according
to a release from Russian Space Agency director Yury Koptev.
-SpaceDaily
** A half-kilometer wide space rock is zooming past Earth barely
12 times farther from our planet than the Moon. In cosmic terms
it's a near miss, but there is absolutely no danger of a collision.
Instead, the encounter offers astronomers an unusually good
opportunity to study a near-Earth asteroid. -James, KD4KLA
** The U.S. government is getting ready to launch a new 267 million
dollar weather satellite it hopes will improve understanding of what
triggers storms, enhance flood forecasts and even offer faster search
and rescue response. The NOAA-L satellite is scheduled for launch on
September 20th from Vandenberg Air Force Base in California. It will
replace a six-year-old satellite that is drifting out of orbit as it ages.
-Florida Today
** Perry, WB8OTH, suggests satellite operators check out a web based
activities logger that is dedicated to satellite operation. The logger is
similar to VHF and HF spotter web sites currently in operation. Take a
look at http://dxworld.com/amsatlog.html. -AMSAT BB
** ANS principal satellite investigator N1JEZ reported that all QSL
cards requests received for the VE1/VO1 portion of his recent trip have
been processed and mailed. Mike also said the FP cards will be sent
soon. N1JEZ added "once again thanks for all the contacts. -ANS
** Starting September 1st, every U.S. amateur is required to fully
comply with the FCC's RF exposure guidelines. U.S. Amateur Radio
operators are required to understand the rules and, where necessary,
perform technical evaluations to determine that their stations are
compliant with the new regulations. Under the regulations, an amateur
station must not exceed the maximum permissible exposure limits for
transmitter operation which are both frequency and power-dependent.
-ARRL
** N9AVG, KE6QIS, W8ZCF, KD4DLA all reported on the AMSAT-BB
about a nice write up on the Science@NASA web site. The story is
about former astronaut Dr Owen K. Garriott, W5LFL, and the thrills
he experienced talking with hams 'down' on Earth. Checkout the
story at http://science.nasa.gov/headlines/y2000/ast21aug_1.htm?list.

** Need a list of Amateur Radio satellites, features modes? Check
out http://www.uk.amsat.org/satfreqs.htm. The web page also has
explanations of modes and the new letter designations to be used
on P3D. -Richard, G3RWL

Uplink 145.850 MHz FM
Downlink 436.795 MHz FM
Launched September 26, 1993 by an Ariane launcher from
Kourou, French Guiana
Status: Software updates underway.
Software upgrades to AO-27 are currently underway. Satellite operators
are asked to refrain from transmitting on the AO-27 uplink. Resumption
of service will be announced on the AMSAT-BB and in ANS.
Jim, K6CCC, reports he copied the AO-27 exciter as it passed near
his QTH recently. He reports a very readable signal and "although
not really very exciting to listen to as it's just an unmodulated carrier,
it was nice to be able to hear it."
An AO-27 question-and-answer page is available on the AMSAT-NA
web site. The URL is: http://www.amsat.org/amsat/intro/ao27faq.html.
AO-27 uses a method called Timed Eclipse Power Regulation (TEPR)
to regulate the on-board batteries. In simple terms, TEPR times how
long the satellite has been in an eclipse (or in the sun) and decides
what subsystems to turn on or off. The AO-27 pages on the AMSAT-NA
web site include an explanation of TEPR AO-27 operations (at):
http://www.amsat.org/amsat/sats/n7hpr/ao27.html

Mode-S Beacon 2401.500 MHz
Launched March 1, 1984 by a Delta-Thor rocket from
Vandenberg Air Force Base in California
Status: Operational.
OSCAR-11 celebrated its sixteenth birthday in space on March 1, 2000.
During the period through August 15, 2000 good signals have been
received from the 145 MHz beacon in spite of low battery voltage
for much of the time. The battery voltage observed during daylight
passes has slightly increased. The average value observed was
13.6 volts, with a range of 13.4 to 13.9 volts.
The internal temperatures have increased by 1.4C during the month
(at 0.4C and -1.0C for battery and telemetry electronics respectively).
This rise in temperature is expected as the solar eclipse times become
shorter.
The operating schedule is as follows:
ASCII status (210 seconds)
ASCII bulletin (60 seconds)
BINARY SEU (30 seconds)
ASCII TLM (90 seconds)
ASCII WOD (120 seconds)
