MIR STAFF CHANGE
HR AMSAT NEWS SERVICE BULLETIN 215.03 FROM AMSAT HQ
SILVER SPRING, MD, AUGUST 03, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-215.03
NASA announced this week that Astronaut Wendy Lawrence (Cmdr, USN)
has been replaced by her backup, Dr... David Wolf, for the next long
duration stay on the Russian MIR space station. The change will
enable Wolf to act as a backup crew member for spacewalks planned
over the next several months to repair the damaged Spektr module on
the Russian outpost.
They stated that reason for the change is that Lawrence does not fit
in the Orlan suit which Russian cosmonauts use for spacewalk tasks
and never undergone spacewalk training. It was stated that Wolf does fit
in the Orlan suit. Lawrence will continue training in the backup role
according to normal procedures, in the unlikely event that she is needed.
To enable Wolf to complete spacewalk training at the Gagarin
Cosmonaut Training Center outside Moscow, the launch of Atlantis
on the next Shuttle-MIR docking mission, STS-86 in September,
could be delayed approximately 10 days. Wolf had been scheduled
for launch in January on STS-89 as the prime crew member for the
final long duration increment on the MIR.
NASA will be conducting their normal safety reviews in
preparation for the transfer of a U.S. astronaut to MIR as was
done before the last shuttle docking mission. This review will
include an evaluation of all the events that have occurred aboard
the MIR since the last docking mission. That final determination
is expected at the conclusion of the formal U.S. review process at
the shuttle program Flight Readiness Review in September.
NASA and Russian space officials have discussed a variety of
options for backup spacewalk capability since the Spektr module
was damaged in the collision of a Progress resupply craft on June
25. It was jointly agreed by both sides that it would be mutually
beneficial to have all three crew members on the MIR qualified for
spacewalks in the event additional assistance is needed from the
U.S. astronaut on the station.
"The Russians usually only fly two people trained for
spacewalks," said Frank Culbertson, Manager of the Shuttle-MIR
Phase One program. "Because of the number and the nature of
spacewalks under consideration by the Russians to repair the
Spektr, we have discussed at length the advantage of having
another astronaut qualified for those tasks."
Culbertson added, "The fact that Wendy does not fit in an
Orlan suit is not unusual. When first selected to fly on the MIR,
it was absolutely normal that she would not be considered to be a
spacewalk qualified crew member. Only because of subsequent
events have requirements on board the MIR changed. As a result,
the joint decision was made to have all three crew members on
board qualified to handle spacewalking tasks."
Lawrence was informed of the decision by Culbertson, who is
in Russia for meetings with Russian space officials.
Because of her knowledge and experience with MIR systems and
with crew transfer logistics for the MIR, NASA will fly Lawrence
on STS-86 in September which will deliver Wolf to the Russian
station. Wolf is fully trained on both MIR and Soyuz capsule
systems.

A0-27 HARDWARE AND USE
HR AMSAT NEWS SERVICE BULLETIN 215.05 FROM AMSAT HQ
SILVER SPRING, MD, AUGUST 03, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-215.05
Michael Wyrick, N4USI, AO-27 Control Operator answers the following
question regarding operation of AO-27:
WHEN CAN AO-27 OPERATE?
The Satellite contains batteries and solar panels and is could run the
transmitters during ANY portion of a pass. Due to power budget limits,
the AO-27 Transmitter can not run all the time. If it did, the batteries
would run down in a week's time. Therefore the AO-27 TX is on only for 17
Minutes a pass. This is a difference in the Amateur and Commercial sides.
The Eyesat-1 commercial Transmitter could be left on all the time at
different power levels.
WHAT HARDWARE IS ON-BOARD?
The Satellite contains 3 Transmitters and 7 Receivers. It also has 5 FSK
demodulators, 2 GMSK demodulators, 2 GMSK modulators, 1 G3RUH modulator, 1
AFSK modulator and 3 analog modulators for sending received analog to any
of the 3 transmitters. There is NO DSP on-board.
WHAT ARE THE DIFFERENCES BETWEEN THE AMATEUR AND COMMERCIAL
SIDES OF THE SATELLITE?
For all practical purposes any RX can be switched to and demodulator and
any TX can be switched to any modulator. AO-27 and Eyesat-1 can both be used
to send Packet (any of the modulations the modems support) and Voice. There
is no real difference from the Amateur AO-27 side and the Commercial
Eyesat-1 side as far as modems are concerned. Both AO-27 and Eyesat-1 can
run the AO-16 microsat style software and can be used as a digital-store-
and-Forward satellite. The Commercial TXs have 16 power levels and the
Amateur TX has only 4 levels.
WHAT CAN THE ANALOG MODE DO?
The Analog mode simply hooks the discriminator of the Receiver to the
varactor of the Transmitter. Tests before launch showed about 30 KHz can be
passed through in this mode. If you can fit it into 30 KHz (well almost)
you can send it through AO-27. Slow-Scan TV, 1200 baud GMSK, 1200 AFSK,
Lets not forget Voice, DOVE (DO-17) Telemetry and a host of other modes have
been sent through AO-27 in Analog mode.
WHAT SHOULD WE BE SENDING THROUGH AO-27?
AO-27 in Analog mode is not a very good way to send Packet. There are
enough packet satellites out there that do a better job. Voice is the
preferred use as it reaches the most people. But from time to time, other
modes should not be ruled out. The slow-scan TV worked very well, and I for
one like to see new ways to use the satellite that we did not think of when
we built it.
SO IF WE SHOULD NOT USE PACKET, WHO IS SENDING
PACKET TO AO-27?
1) The uplink 145.850 is very close to other satellite uplinks. LO-19 has
Uplinks at 840 and 860 that pass through the Analog passband. When LO-19 is
in the sky at the same time AO-27 is, you can hear uplinks from ground
stations.
2) There is ground based packet station that don't pay attention to band
plans, it comes up on the Analog passband. (you can decode some packets with
a TNC to see who).
WHAT CAN WE DO?
Just enjoy the satellite when you can. Most people enjoy making contacts
and don't worry about the interference picked up by the receivers. If we
had built deaf receivers so only 5 KW EIRP could make it into the satellite,
there would be far less contacts from low power stations and many of you
would never have known that AO-27 was available.
If you do happen to decode a packet callsign, just drop them a nice note.
I have called several stations that were using packet and some that were
using simplex voice that never knew they were operating on a satellite
frequency. If you demand they move, you might be surprised just how strong
their signal becomes in the following weeks.

K2BSA MIR CONTACT
HR AMSAT NEWS SERVICE BULLETIN 215.06 FROM AMSAT HQ
SILVER SPRING, MD, AUGUST 03, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-215.06
K2BSA, the official callsign of the Boy Scouts of America used at the
National Boy Scout Jamboree in Fort A.P. Hill Virginia, has for the last
week been contacting amateurs on all frequencies including satellites
RS-12, FO-20, and FO-29. Over 30,000 scouts are attending the Jamboree
and many of those have been introduced to amateur radio, earned their
Radio Merit Badge, or have passed their amateur exams.
Of particular interest was the contact arranged with Mike Foale, KB5UAC,
aboard the MIR space station on the morning of August 1st. Over 200
scouts, some hiking for more than an hour from their campsites, came to
the K2BSA demonstration station at 4:30 am EST to witness the contact.
Mike was able to talk to 10 scouts during the MIR pass. He also had a
conversation in Russian with one of the visiting scouts from
Siberia.
During the contact, Mike made note that this was the first time that he
was able to make a group contact and that this was the first time that
the Moscow ground station could simultaneously listen to the contact.
Mike also mentioned that he was involved with scouting in Germany at one
time. This was the first ever amateur contact between Scouts at a
National Boy Scout Jamboree and a Scout in orbit.
Scouts were amazed at the strong signals and that MIR could be viewed
with the naked eye. A staff member overheard one of the scouts
commenting after the MIR contact, "this kind of makes you want to look
up in the sky more often..."
Thanks to Dave Larsen, N6CO, president of the MIREX team, for arranging
the MIR QSO. This contact has made a significant impact on the scouts
that is sure to be felt around the country as the scouts return to their
hometowns on August 7.

OSCAR-11
(Downlink 145.825 MHz. FM, 1200 Baud PSK. Beacon 2401.500 MHz..)
Operating normally.
An uneventful month for OSCAR-11. During the period 20-June to
17-July excellent signals have once again been received from the
145.826 MHz. beacon. The improved signals may be partly due to
increased power output resulting from lower beacon temperatures. In
the UK the change to Summer time, and the lighter mornings make the
early morning passes more socially acceptable. There is less
electrical interference and splatter from mobile radios in the early
mornings than in the afternoons.
The mode-S beacon has been heard by Dean, AL7CR in Anchorage, Alaska,
and from Joe , K0VTY, located near Omaha, Nebraska. Joe used a 60 cm
dish, Down East converter, into a Kenwood TR-781, with a Time Wave
DSP-9 filter. Telemetry nominal. The battery voltage generally around
14 volts. The internal temperatures reached minimum values
(battery -0.4C telemetry electronics -1.6 C), and have now started to
rise. The minimum value of solar illumination was about 72% of full
sunlight. Temperatures should now increase, as the solar illumination
reaches a peak of about 97% in October.
Two WOD surveys of channels 10, 20, 30, 40 (+Y, -X, +X array
currents, array voltage) dated 07-June, and 25 June respectively,
have been transmitted.
A single AMSAT-UK bulletin by Richard G3RWL has been uploaded. This

like a carrier with lots of Doppler. If you receive equipment is working
well you will hear the 'buzz' from the flags and an occasional change in
the sound of that modulation as a telemetry beacon is sent. If it's
working really well and you run the received audio through a PSK demod then
a tracking notch filter (DSP) you will clearly hear the flags and
modulation. In the northern hemisphere there will be deep fades about
every 30 seconds due to the rotation of the satellite. In the southern
hemisphere there will probably be some fades but not nearly as deep
because the antenna points down when below the equator.
