We switched it to 9k6 digital to try to figure out what happened. 9k6 sounds an awful lot like white noise.
My gut reaction is the reversed cell failed again, this time to a dead short, and the remaining cells were enough to keep it running through eclipse. We also saw a 10 degree C drop in battery temperature between the first and second pass, indicating some sort of big change. At this point we are going to observe for a bit to firm up our hypothesis, then we will try to load the software, get some WOD, and get the transmitters shutting off during eclipse. Observations right now from when the satellite goes into eclipse would be -very- helpful.
Exciting times, but I'm trying to guard my optimism.
