Arissat-1 sstv too weak for my station to copy.

Since the battery deteroriation, in sunlight or not, I am no longer able receive clear sstv images on 145.950 with my usual pre-amp/vertical antenna setup. Signals are too weak despite multiple passes and incident angles. My copy was fantastic when ARISSAT first transmitted, now nothing clear. If no fix, the satellite sstv is no longer accessible from my location or setup.

signals

For ARISSat-1, the answer is that the satellite can now only operate in sunlight as it appears the battery can no longer support a charge. Operations are supported by the solar panels only now.

For ISS, (just a guess) Russians probably powered it off to support an experiment and forgot to power it back on. Should come back after the next school contact (scheduled for Aug 25).

Loud & clear signal from ARISSat-1 here

Not the same thing here ;) On a 18:02Z pass over the area where I am right now (Arén, Spain, IN92pg) I was able to receive an incredibly clear signal from ARISSat-1, not very strong but as I've said very clear and very loud, with almost no fading or static noise while the sat was overhead (in fact I think it's been the ARISSat-1 pass in which I've received the clearest signal of all). So all I can say is that when it passed over here it was fully active and in High Power Mode.
