The control station is actually performing some tests to the satellite. The satellite is sending telemetry on 437.125 MHz and it's digipeater still turned on. Overseas stations: If you capture any LUSAT-1 telemetry and send it in raw-mode to the satellite control station, you'll receive a certificate for your collaboration. These telemetry reports can be sent either via packet radio to LU8DYF@LU8DYF.BA.ARG.SOAM and LU8DYF@ANY-ACTIVE-SATELLITE, or via Internet to: lu8dyf@asarin.org.ar If you intend to use the satellite, please remember that the BBS is NOT LOADED and it will NOT be operational for the next 2 weeks (approx.). The LUSAT-1 recovery team want to thanks all the stations that sent LUSAT-1 telemetry data in RAW format. The overseas stations that are going to receive the Special Award are: 1) Mr. Norimasa Okamoto (JN2LHU) from Gamagori city, Japan. 2) Mr. Bent Bagger (OZ6BL+OZ7SAT) from Denmark. 73's de Eduardo Sweet, LU7AKC (LUSAT-1 recovery team) packet: lu7akc@lu7akc.#col.cf.arg.soam e-mail: lu7akc@asarin.org.ar ------------------------------ Date: Mon, 30 May 1994 18:20:18 MET From: ihnp4.ucsd.edu!dog.ee.lbl.gov!agate!howland.reston.ans.net!xlink.net!nntp.gmd.de!dearn!esoc!estec!sbadessi@network.ucsd.edu Subject: RS10 trans-Atlantic contacts.

I helped the Raleigh Amateur Radio Society with a successful SAREX contact in '92. In our application we pointed out that we had already made one SAREX demonstration to the school, without a scheduled contact. I've seen other schools try this before applying. (The attempt was not successful -- we didn't even hear the shuttle, but that didn't matter.) We maximized the number of students exposed by setting up stations at several schools, linking them together by repeater. The entire contact was also broadcast on the local repeater, and monitored in a dozen more schools, and countless offices. And we promised a big publicity effort (my job). That was very successful, with a live telecast on the local FOX affiliate, and two nights of coverage on the news of the other market stations, plus lots of radio news and newspaper coverage. I generated several press releases that I faxed to the media, but it was the followup phone calls that got their attention. Once they realized the potential of the story, they were eager to cover it. Our "earth" station was a good OSCAR-type satellite station, with 400 watts RF out to a circularly polarized, steerable antenna. The antenna was important. The power was overkill. The 5-watt signal from the shuttle was "pegging the needle" for most of the pass. The first and last minutes of signal were distorted by doppler effect. We were late in recognizing and compensating for that. Our contact lasted 8 minutes... almost horizon-to-horizon. We had 4 kids, and each got to ask at least 4 questions. Before and after the contact, our "control station" on the repeater described what we were doing, and what people could expect to hear. I have a professionally produced videotape of both our "dry run" practice exercise, and the contact itself. If you would like a copy, I'll make you one for the cost of duplication and handling ($12). It will be a good way to see how it happens (at least here in Raleigh) and spur interest with club members in your area. 73, and good luck with your application (and contact!), Gary Pearce KN4AQ 4400 Bleeker Ct.

Apparently, one of the crew members is the uncle of a couple of the students at the school. I'm not sure at the moment exactly which shuttle mission they're interested in but I think it's early next year. We have the application and there shouldn't be any problems with technical expertise but what else should they (the school) send in with the application? I would think some kind of proposal that addresses how they intend to fit it in with the curriculum would be in order. Can anyone offer any advice on how to proceed with this? I'd be interested to hear from anyone who has participated in a SAREX school sked. Any info (logistical, technical, etc.) will be appreciated. Thanks & 73...
