Thanks all for the input - very nice of you.
I studied it a little closer and discover another clue. SatPC32
tracks the Doppler just fine. It's SatPC32ISS that's lost it's
mind. If I watch the download frequency in SatPC32ISS update it
starts deviating from the correct frequency within a second or two
after starting SatPC32ISS. It starts at the correct base
frequency I have in the Doppler.SQF file (derived from tuning to
GreenCube in SatPC32) but then at different rates per run session
it takes off and starts jumping up in frequency in steps way to
large, until it's jumping in some cases as much as 10-20 KHz are a
time! Obviously, after a jump or two I'm off frequency too far to
operate. Most of the times the jumps are small so I didn't notice
them at first, thus the drift off the correct Doppler-adjusted
frequency is too small to notice other than in the waterfall where
the signal starts drifting to the left.
My install of SatPC32ISS is new, I just updated to V12.10. V12.9
was acting the same way. Now I just need to figure out what's
making SatPC32ISS lose it's mind.
