This is the Second Call for Papers - Those who wish to present papers at this event, should forward their request together with a title by April 1 1997. Topics may include all relevant Amateur Satellite disciplines. Abstracts are required by June 1 1997 with final versions by August 1 1997 (so that they may be printed in the proceedings). We also encourage those not able to attend to send papers for inclusion in the proceedings of the symposium Submissions and esquires should be made to:- Wayne Chandler, VE3WHC by internet: ve3whc@amsat.org (apologies to those who tried and could not get in earlier) By Mail Wayne Chandler Box 6, Carlisle, Ontario Canada.

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.

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.

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.

RS-10: (Uplink 145.865-145.905MHz CW/SSB, Downlink 29.36-29.4MHz CW/SSB) RS-10 has strong downlink signals.

[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.

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.
