ARISSat-1 Transmissions over North America Thursday PM
During the 2320Z pass of ARISSat-1 over North America this evening a number of changes to the 2m FM transmissions were noted.
1) Male voice for telemetry means that the female voice files on the SD card could not be read 2) No greetings, mean that the greetings stored on the SD card could not be read. 4) MET of 2M while the satellite was still in a long period of sunlight - satellite must have reset during sunlight 4) FM transmissions consisted of voice ID, male telemetry and SSTV image in rotation
Please send your BPSK telemetry into the server.

Gould,
For what it's worth, the linear transponder sounded good. I had a quick QSO with K3SZH.

Hmmh, interesting. The 02:30z pass this evening over CM98 sounded like normal low power mode. Female announcement, switched to foreign language (sounded German), SSTV picture (canned), few minutes of silence, then more talking, then silence to LOS. No voice telemetry, and I'm not set up to record the digital stuff.
This was a directly overhead pass (on the correct side of vertical for a change!). Next pass is in 27 minutes, 15 degrees up to the North West (my good horizon shot). Will report back what I hear.

Hi Gould,
Ok, 04:01z pass over CM98 in Northern Calif... Max elevation 15.6 degrees, to the North North West.
Pass started with a foreign voice (Russian, I think). Then there was a USA welcome message (with the USA Secret Word), and an SSTV image. Not sure which one, as there was too much noise and QSB to copy. I think there was some silence, followed by voice telemetry. Signal strength came way up just in time for a clear copy.
MET = 53 min IHU Temp = +30c Control Panel Temp = +31c Battery voltage = 35.74v Current = -12ma
This was followed by 2 min of silence, and English spoken announcement (not sure which variety of English), some children chanting, and another break for silence. The pass ended with SSTV right at LOS (no copy on the picture - way too much noise).
Seems like a normal low power pass...

I listened during part of the same pass here in DO33. Due to ARISSat's position and my location, I wasn't able to hear more than a few seconds of the transmission. It was up to S8 on my radio's S meter but it was noisy for much of it.
I heard part of the children's segment followed by a few seconds of open carrier and then no signal.

Do we know which callsigns were sent out over CW? There's a limited set of 32 CW Ids that are sent when the SD card is not available. Also, did we get any of the stock SSTV images?
Are we still seeing this? I pulled the one of the latest STP files (201108182126711), and it's indicating that call signs are being sent from the SD card currently, and the MET is 1h 7s.
I didn't instrument the FM mission enough to be able to tell from the telemetry stream if it's getting more from the SD card or not, unfortunately.
