Hi Mark,
Glad you're collecting frames! I haven't really seen a drop lately-at least I haven't noticed. There is variability, usually due to changes in times of the pass (e.g., is the transmitter even on at very odd hours in the night?), and sometimes they can share a footprint, so you typically get frames from one but not the other. So frames can vary.
I have from time to time seen that a restart of Foxtelem is necessary; I don't do it daily, but close...not sure if the decoder just needs a restart from time to time, or what. It's pretty stable and consistent, for sure. I just do it more often than necessary so I can keep a watch on daily frame rates (basically resetting the counter...)
You can watch what others are getting framewise here (thanks to spiffy coding by Chris AC2CZ!) A bit of clicking and you get an idea of daily/weekly/monthly frames captured.

Hope it clears up for you. Not sure this was any help, but I tried ;)

For weeks I have been successfully capturing 30-60 telemetry frames per pass on AO-91 and AO-92 with FoxTelem v.1.08z5.
But suddenly, over the past week or two, I'm lucky to capture 10-20 frames in a pass -- sometimes as few as 1 or 2 frames for a 25 degree elevation pass! The eye just doesn't seem to want to lock up, even when the downlink signal is very strong.
Nothing has changed in my station. Is something different with the DUV signals of the satellites, or with the program, or some screwy Windows update, or something else that I'm missing? Anyone else seeing the same? -- Mark D. Johns, KØJM AMSAT Ambassador & News Service Editor Brooklyn Park, MN USA EN35hd
