OK, found a problem. The output of a 9700 is not a true IQ signal, but you get two "humps" on foxtelem a left and right "hump". if you are decoding from the "left" side you get zero decodes, decode from the "right" side and it decodes from a wav.
Now I need a sat with a live signal.

Kevin,
I just played your recording through 1.08p. Recovered 25 frames, which is about what you expect. More evidence there is another variable involved.
