Somehow my set-up for ARISSat BPSK decoding is not working.
My I kindly ask for your suggestions ?
Using an FCD HDSDR I record the passes.
When I play back I see this freq spectrum.
Should such a result (S/N Ratio wise) be enough for the decoder to work ?

Well, I'm back from the CM79/CM89/CN70/CN80 grid expedition. It was

Answer: Yes.
In the upper left corner of the main screen are the option selection boxes.
There is an M which when selected will give you multitrack and show
multiple footprints. You can select the particular ones by opening the
Satellite Menu, and selecting the one you want by clicking once.
Let me echo Clint Bradford, K6LC's question:

Not missing anything. Guess you didn't see my tongue in my cheek. in

There appear to be two different TV camera views that have some parts of

I viewed the ARISSAT SSTV gallery website
(http://www.amsat.org/amsat/ariss/SSTV/) and viewed images that had a green

And I say 'maybe'
With the rudeness that has become the standard on the fm sats, it is an
every day event where you hear someone call, you respond to that particular
call, and someone will climb all over the pass calling someone else.
In Jon's case he is just asking for some help on a call sign.
