Things seem about normal. You can sometimes get periods when due to antenna alignment the signals are
weaker than you would expect, but is usually something which only applies to a single pass. Some
things to check are the source gain, and also make certain that the AGC is not selected. Many version
of SDR# ago, I found that if the AGC was selected, it greatly reduced the data recovery on AO-85.
Haven't checked lately.

<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.
