Hi Steve,
I haven't been copying AO-85 telemetry for the last few weeks, but I have not heard any reports from our engineering team that there are any anomalies with the telemetry. The presence or absence of sunlight over the northern hemisphere or anywhere else should not affect the signal strength of the satellite, at least not noticeably.
A quick look at the telemetry leaderboard http://www.amsat.org/tlm/leaderboard.php?id=1&db=FOXDB indicates that there are as many stations as usual copying telemetry in the last 90 minutes. So while everything I've said here doesn't conclude that AO-85 is working OK I don't see any obvious indications that there would be a problem on the satellite end of things.
I'm sure that others here can help with suggestions for troubleshooting on your station end, I'm not taking a cop-out here but it is in fact suppertime so here I go for now, stomach wins over hobby! :-)

I just tried to get telemetry from AO-85. The pass had max elevation of 76 degrees here. In the past I would get lots of data on a pass like this, but lately I've been getting nothing. I can see the signal on the "waterfall" (using SDR#) but the signal is too weak to decode. Is anyone else having this problem? Is the signal normally low when the northern hemisphere is dark? What's happening?
I've asked this before and didn't get any responses. Please send a couple of responses so I have some idea if there is some problem in my set up here.
Thanks!
