AMSAT-UK 12TH COLLOQUIUM

HR AMSAT NEWS SERVICE BULLETIN 075.02 FROM AMSAT HQ
SILVER SPRING, MD, MARCH 16, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-075.02

The 12th AMSAT-UK Colloquium will be held at Surrey University, Guildford,
Surrey, U.K., from Friday 25th to Sunday 27th July 1997. This year's event
will comprise three days of technical and operational matters only; there
will be NO "political" subjects.

Amsat-UK invites authors to submit papers, about amateur radio space and
associated activities, for this event and for the "Proceedings" document
which will be published at the same time. It is normally preferred that 
authors present the papers themselves rather than having someone else read 
them in the authors' absence, but AMSAT-UK also welcomes "unpresented" 
papers for the document.

Abstracts of Papers should be submitted as soon as possible; the final date
for acceptance has not yet been finalized but is likely to be 15 June 1997
in order that the "Proceedings" document be available to participants.

Submissions should be sent *ONLY* to G3RWL, via the following routes:

Internet e-mail:  g3rwl@amsat.org
Packet Radio:     G3RWL @ GB7HSN.#32.GBR.EU
Satellite:        AO16/19/22/23/25
Terrestrial mail: R W L Limebear G3RWL
                  60 Willow Road
                  Enfield EN1 3NQ
                  United Kingdom.
AMSAT-UK also invites anyone with requests for Program Topics (and possible
authors) to submit them as soon as possible to G3RWL as above. Invitations
for papers on specific subjects will be included in the final call, at the
end of April.

Information about the Colloquium will shortly be available on the World
Wide Web pages at the University of Surrey on:
http://www.ee.surrey.ac.uk/CSER/UOSAT/amateur/colloq97.html

A change to the booking requirements has been made this year] such that 
AMSAT-UK will accept unregistered day attendees subject to space, but they 
will not receive a free lunch. As usual, facilities will be available for 
attendees who wish to arrive at UoS on the evening before the event starts.

This year a healthy coverage of microwave-related material pertinent to 
the advent of the P3D satellite will be presented, and that there will be 
microwave test equipment available on the Friday evening for people to
check 
their home projects. Availability of application forms to attend the
Colloquium will be publicized later in the year.

NOTE: All other inquiries about colloquium-97 should be sent] to the
AMSAT-UK 
office: AMSAT-UK London e12 5EQ

MIR MISSION UPDATE

HR AMSAT NEWS SERVICE BULLETIN 075.03 FROM AMSAT HQ
SILVER SPRING, MD, MARCH 16, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-075.03

U.S. astronaut Jerry Linenger, KC5HBR, has reached the halfway point of his
mission aboard the Russian space station Mir, today is his 62nd day in
space. For his two Russian crew members, its their 33rd day.
The primary oxygen generation system has been off-line for a week
now. The Electron system shut itself down last week due to excess build up
of air. Both Electron systems are having problems, Electron 2, which was
their primary system has a filter bypass problem, some spare parts will be
coming up on the next Progress cargo ship. Electron 1, in the Kvant 1
module is having pump problems. Spare parts are a problem, but some are
being manufactured right now.

Scheduled Activities
--------------------
Apr 6- (TENTATIVE) Progress M-34 Launch.

Apr 8- (TENTATIVE) Progress M-34 docking.

RS-16 LATEST

HR AMSAT NEWS SERVICE BULLETIN 075.04 FROM AMSAT HQ
SILVER SPRING, MD, MARCH 16, 1997
TO ALL RADIO AMATEURS BT
BID: $ANS-075.04

B.J. Arts, WT0N, reports that during the March, 14th, 1740 UTC pass over
North America, RS-16's 10 meter, 29.408 , 29.451 MHz, beacons were not
heard. The 70 cm, 435.504  MHz and 435.548 MHz, beacons were active at that
time. The 435.504 MHz beacon was very strong, an S-9. The 435.548 beacon
was very weak, an S-1. WT0N tried the passband on 2 meters, 145.915 -
145.948 MHz, and listened on 10 meters, 29.415 - 29.448 MHz . He did not
hear his downlink signal and assumes that the transponder is not yet
active.

Here is the example of 435 MHz CW telemetry, received by UA3CR on the
12.03.97 orbit number 134, over Moscow. 
Below are some important parameters:

MIR: 
(New frequencies implemented 1 January 1997:
Uplink 145.2 MHz FM
Downlink  145.8MHz FM) 
Note, the above split is used for both packet and voice operation.

SAFEX, MIR 70cm Repeater
(Uplink 435.750MHz FM, Downlink 437.950MHz FM, 
Subaudible tone 141.3 Hz)
The repeater operational and active..

RS-10: 
(Uplink 145.865-145.905MHz CW/SSB, Downlink 29.36-29.4MHz CW/SSB) 
RS-10 has strong downlink signals.
[ANS thanks Mark Herrick, KL0AD, for this report.]

RS-12: 
(Uplink 21.21-21.25MHz CW/SSB, Downlink 29.41-29.45MHz or
145.91-145.95Mhz CW/SSB) 
The sat continues to provide excellent downlink signals in both T- 
and K-mode. 
[ANS thanks Dick Montgomery, N3DV, for this update.]

RS-15
(Uplink 145.858-145.898MHz CW/SSB, Downlink 29.354-29.394MHz CW/SSB) 
RS-15 was a little weak on the downlink and the satellite spin puts a twist
in, but you can time the important exchanges around that "null".
[ANS thanks Mark Herrick,  KL0AD, for this report.]

Be aware that RS-15 has battery charging problems. When the satellite is
in the dark it has low output power..
[ANS thanks Geoff Perry  for this report.]
(Hint: If SSB doesn't work for you, try CW. CW is very easy
to hear on the downlink!)

RS-16
RS-16's 70 cm, 435.504 Mhz beacon on RS-16 operational. The 10 meter beacon
is not active at this time. Transponder is not operational.

FO-20 
(Uplink 145.9-146.0MHz CW/LSB, Downlink 435.8-435.9MHz CW/USB) 
Operating normally. Strong downlink signal.

KO-23 
(Uplink 145.85, 145.9MHz FM, Downlink 435.175MHz FM,
9600 Baud FSK.) 
KO-23 operating normally.

KO-25:
(Uplink 145.87MHz FM, Downlink 436.5MHz FM,
9600 Baud FSK.)
KO-25 operating normally. 
[ANS thanks Jim Weisenberger, AA7KC, for his reports on
KO-25 and KO-23.]
 
AO-27:
(Uplink 145.85MHz FM, Downlink 436.8MHz FM) 
Operating normally and lots of activity heard over
North America and Europe.
As of NOV 2, the AO-27 schedule is as follows:
  TEPR 4 = 16 = 8 Minutes in Length
  TEPR 5 = 52 = 18 Minutes in Length

  TX-3 is on Mid Power during TEPR 5.

This will have the TX turn on 8 Minutes after the satellite
enters the sun for a duration of 18 Minutes. This is a "back to US
Latitudes"operation.

N4USI, AO-27's current Command Station sends his thanks all for
their messages about the satellite turning on later than expected. He
reports he's deliberately letting the "turn on" time drift later
(for about 4-5 Minutes) so stations in the southern latitudes can also
have a chance to work AO-27.  Every few months he will be letting the
turn on time drift like this to give more stations a chance to make
contacts thru the satellite.

Menendez, EA1BCU, for this update.]
