Hello, ISS Status report for 4/13/2011 says: "...Dmitri performed hardware deactivation & close-out activities on the TEKh-43 Radioskaf-B "Kedr" test microsatellite in the MRM2 Poisk module which had been connected to an 825M3 Orlan battery..." So, we are done for now. More to come in July. Stay tuned. http://www.nasa.gov/directorates/somd/reports/iss_reports/index.html 73, Armando N8IGJ

Hopefully, this is the last of the equipment. I found an old FODTrack board. It is built, but it is not in an enclosure. Last time I used it with InstanTrack, it worked fine. I still have the Icom AG-25 2m preamp and an unmodded CalAmp 31732. FODTrack: $75 OBO AG-25: $90 OBO CalAmp 31732: $30 OBO (Mod details are here: http://www.qsl.net/n9zia/wc0y/index.html) Posting on QTH.com also. 73, Joel - W4JBB

Re: Space-track downloads working?
by Richard John K7MDH 13 Apr '11

Thanks for the info, the change to https: explains everything. I have just discovered that I can manually download a compressed file from Space-Track, extract the text file, and manually update Nova from the text file. Looks like Celestrack could make that process a lot easier, so I will explore that next. Nova hasn't been upgraded since 2008 ( and it had so many little bugs to fix !! ) so I'm not going to sit around waiting to see if they put out a new version. Thanks again, Richard K7MDH

ARISSat-1 battery.

Hi Nitin / Vince. Although the non appearance of ARISSat-1 has been a little disappointing, in the overall scheme of things we are still looking at a major AMSAT achievement here. There is after all a satellite awaiting 'launch' on the ISS. We know it's a success because so many people have named it and want it to be identified as belonging to them. We even have some working telemetry decoding software 3 months ahead of launch. - Yipee. I'm really not sure what all the confusion over the last few days tells us. Prepared press releases full of mistakes, a complete lack of preperation following the long period of testing which left the battery delpleted. No plan B to charge it during the sleep period - One wonders if the switches were even returned to the correct positions when it was last turned off. Despite a turbulent last few days, the main event is yet to come and as long as the designers have anticipated it being deployed with a completely flat battery, then we can all sit back and wait for July more prepared from this rehearsal than we would have been.

Maybe in two months pass the time since it should launched, even though it was off there might have been a small drain on the batteries and now they're in a discharge state. KB7ADL

schrieb Greg D. am 2011-04-13 07:18: > I did hear a frequency drifting carrier around 145.920 that disappeared about the time the Station set, but the carrier was RISING in frequency, which is inconsistent with a satellite. We had a reasonable pass at 22:59 UTC here at OE6XUG, Austria JN77, and we heard something similar: Rising carrier, and something that could have been BPSK. The only recording device was a digital voice recorder, I hope the compression leaves something for identification or decoding.
