UO-14 IN FM MODE
AMSAT NEWS SERVICE BULLETIN 058.01 FROM AMSAT HQ
SILVER SPRING, MD, FEBRUARY 27, 2000
TO ALL RADIO AMATEURS
BID: $ANS-058.01
The latest ARRL Letter reports UO-14 is proving that you can 'teach an
old bird new tricks'. The venerable British satellite recently was switched
to Amateur Radio operation -- in a FM repeater mode much like AO-27.
Chris Jackson, G7UPN / ZL2TPO reported on the AMSAT bulletin board
that UO-14 --launched in January 1990-- spent its first 18 months in
orbit operating as a store-and-forward satellite. It was then switched for
use by Volunteers in Technical Assistance, who used it for medical
messaging into Africa. "Since the computer which is used for
store-and-forward communications is no longer able to perform that task,
UO-14 is no longer usable in this mode," reported G7UPN. "It is, however,
possible to use the satellite as a single-channel FM voice repeater, and I
have configured the satellite to do this."
The satellite works as a FM bent-pipe repeater in full duplex. The uplink
is 145.975 MHz and the downlink is 435.070 MHz.
Houston AMSAT Coordinator Bruce Paige, KK5DO, says no more than
5-watts is required to make a contact with UO-14, and some have made
it with much less. "Cool satellite!" was the reaction of W1AW Station
Manager Joe Carcia, NJ1Q. ANS Principle Satellite Investigator Mike
Seguin, N1JEZ, told ANS "it's nice to have an FM bird around at night."
Operation is also reported to be heavy over other parts of the globe in
addition to North America. Both VK3JT and G7NFO reported several
contacts via UO-14.

ARISS CREWS RECEIVE TRAINING
AMSAT NEWS SERVICE BULLETIN 058.02 FROM AMSAT HQ
SILVER SPRING, MD, FEBRUARY 27, 2000
TO ALL RADIO AMATEURS
BID: $ANS-058.02
The first International Space Station expedition crew and its backup crew
have received training on the use of the initial U.S. provided Amateur
Radio ISS station. The equipment will be installed as part of the initial
ARISS effort on the International Space Station.
The training session was conducted at the Gagarin Cosmonaut
Training Center in Russia.
As part of the ARISS training effort, NASA's Matt Bordelon, KC5BTL, has
prepared a consolidated schedule for training in the United States and
Russia that will include familiarization with equipment, packet theory
and hands-on simulation. The ARRL reports that the training will focus
on general principles of ham radio as well as preparations to use
station equipment-operating modes, including software.
Bordelon has held an initial training session with astronauts and
cosmonauts that provided exposure to the actual hardware. Other
training has included information required to obtain an Amateur Radio
license.
The first ISS crew will include Bill Shepherd, KD5GSL and Sergei
Krikalev, U5MIR.

SILVER SPRING, MD, FEBRUARY 27, 2000
TO ALL RADIO AMATEURS
BID: $ANS-058.04
ANS news in brief this week includes the following:
** Peter, KD7MW, recently received his OSCAR Satellite WAS award.
Congratulations from ANS! -NN0DJ
** The Canadian special event call sign VC4X has been assigned for
use through March 26, 2000 -- to commemorate the 50th anniversary
of the 1950 Winnipeg Flood. -Derrick, VE4VV
** This year could be one of the worst for solar storms -- surges of
charged particles that knock out satellites, power grids and even
garage door openers. No one can predict which month or week will be
worst, but the sun is at the height of its 11-year cycle of storms, which
means the Earth can expect several barrages of excess charged
particles. -Reuters
** The Galileo spacecraft made its third and closest flyby of Jupiter's
volcanically active moon Io. The spacecraft passed only 199 kilometers
above Io's surface. Although battered by Jupiter's strong radiation,
Galileo continues to provide useful imagery and other data, now
operating under its second mission extension. -S&T
** Two Vermont hams, Bob, N1MEZ, and Lloyd, W1CX, have recently
departed for PJ8 land, vacationing for the next two weeks. They have
a tripod mounted VHF/UHF beam antenna and a pair of HT's with
receive preamp, and will attempt to operate AO-27 and possibly UO-14.
Operation may also take place on RS-13 (SSB) and RS-15 (CW). The
grid should be FK88. -Mike, N1JEZ
** Over the past six months, the Southern Hemisphere of Mars has
passed through spring and into summer. Spring started in early
August 1999 and summer arrived toward the end of December 1999.
On Earth, we are about to observe our first leap day with a year ending
in 00 since the year 1600, nine years before Galileo used his first
telescope! -S&T
** The restructuring of Amateur Radio licensing in Israel earlier this
month brought an extension of frequency privileges for some license
classes. The code-free Grade D license has had band access extended
to 50 MHz, 1.2 GHz and 5.6 GHz. The Grade A license now has access
from 2.4 - 2.45 GHz and 5.275 - 5.875 GHz. -AR Newsline
** Some North American doorstep astronomy -- the brightest star
nearly straight overhead as twilight fades is Capella. The brightest
light in the west-southwest is Jupiter and the brightest in the
south-southeast is Sirius. Sirius appears so bright because it's very
close as stars go, only 8.6 light-years away, and it really is bright,
putting out 22 times as much light as our Sun. -S&T

Uplink 145.850 MHz FM
Downlink 436.795 MHz FM
Operational, mode J.
Tony, W7EWC, tells ANS he plans to be active on AO-27 from the
Bahamas as W7EWC/C6A during the entire month of March. Markus,
HB9JNH, will be operating from Svalbard as JW/HB9JNH from March
2-5th.
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 AO-27 operations (at):

Downlink 435.120 MHz FM
Operational.
Chris Jackson, G7UPN, reports to ANS that UO-22 has now entered full
sunlight and the temperatures have increased considerably. Controllers
have turned the satellite upside down to point the critical systems to cold
space. This has reduced the temperature on various systems (such as
the batteries) by between 5 and 10 degrees. The unfortunate by-product
of this is that the downlink is now quite weak.
The satellite will remain in full sunlight until late March, when
controllers
will turn it back 'over' again. According to G7UPN "over the next few
years this situation will become worse as the no eclipse periods become
longer."
Only the 145.900 MHz receiver is usable for communications at the
moment.

Efforts were reported to be underway to bring GO-32 on line,
however no additional information has been received by ANS
since November 1999.
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.

PANSAT PO-34
Uplink/downlink frequencies have not been established.
The satellite is not currently available for general uplink transmissions.
PanSat, developed by the Naval Postgraduate School, was launched
from the shuttle Discovery during STS-95. PanSat spread-spectrum
digital transponders will be available to amateur radio operators in the
near future along with software to utilize this technology.
For more information, visit the official PanSat web site at:

PanSat was the featured cover article on the July/August 1999 issue of the
AMSAT-NA Journal (written by KD6DRA and N7HPR).

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.
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
Not operational. No operation in 1999 or 2000 has been observed.
MIR SAFEX II 70-cm QSO Mode
Uplink 435.725 MHz FM w/subaudible tone 151.4 Hz
Downlink 437.925 MHz FM
Not operational. No operation in 1999 or 2000 has been observed.
MIR PERSONAL MESSAGE SYSTEM (PMS)
Uplink/Downlink 145.985 MHz FM 1200 baud AFSK
Not operational.
DOVE DO-17
Downlink 145.825 MHz FM 1200 baud AFSK
2401.220 MHz
Non-operational.
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
Downlink 437.104 MHz SSB 1200 baud PSK AX.25
Non-operational.
WO-18 is reported to be in MBL mode after a software crash.
No additional information is available at this time.
SEDSAT-1 SO-33
Downlink 437.910 MHz FM 9600 baud FSK
The satellite is not currently available for uplink transmissions and
image and transponder recovery efforts have been unsuccessful.
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.
SedSat-1 has downlinked months worth of telemetry data on the
performance of its electrical power system parameters. The Nickel
Metal Hydride batteries on the spacecraft were experimental and
experienced some abuse due to a power negative situation. This
information has provided NASA with useful information. With the
exception of the imaging system and the use of the transponders,
SedSat-1 has been judged a success.
