hmm, that one's not in my Orbitron list.... If I add it's Keps to my "amateur.txt", they'll get wiped-out in the next update. Anyone know how to prevent this?

Hi Auke,
If you are listening for supposedly "dead" amateur radio satellites, then you might also want to listen for SSETI Express on 437.250 using NBFM. SSETI went silent shortly after launch. If it ever wakes up, you should hear 9600 baud data signals on 437.250. This will sound like white noise - slightly different than static.

Hello List,
With the recent "resurrections" of old sats lately, I have decided to do some listening for other old sats which might, one day, un-fail. I think that the most likely ones would be Oscar-6 and Oscar-8. According to what information I have found thus far, their original modes of failure were battery-shorts a-la AO-7/AO-40, therfore they might also un-short based on my extremely limited knowledge of their design(assumptions comparing to ao-7) and regain their power supply. The problem that I am having, is that I can't find much information about AO-6's beacon transmitter frequencies for which to listen. Can anyone here offer some information about the beacon transmitter frequencies used for AO-6, and perhaps any other tech info such as how they might behave without command-station intervention?

OOps! I just realized that it is indeed on the list, under it's other name: XO-53. My bad.
BUT, I still wouldn't mind finding out how to add custom TLE's into Orbitron's existing files permanently.

Hi All,
Yes the SSETI Express team would be really delighted to have any reception reports as most of the SSETI Express Groundstation network infrastructure around Europe has now been redeployed to track other satellites....
The data format one might hear would be one of the following depending on bus voltages:
a short, less than one second, burst of 9k6 AX25 telemetry either every 18 seconds - the Nominal Beacon or
a simple plain carrier Pulse Beacon with 1.6 seconds of CW like transmission every 30 or 120 seconds
More details are available here: http://www.sseti.net/the-express-mission/space-craft-beacon.html
Currently however the decoding software appears no longer available for download - I will try to see what can be done about that!
thanks
