[amsat-bb] IC-9700 & FoxTelem 1.08p

[Kevin]

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.
