Fine Business Steve - that's what open source is all about. That modem
and protocol is so sensitive you might be about to pick up our South
Australian balloon telemetry from over there ;)

I found the 4FSK modem project kind of fascinating, especially since the
interleaving and scrambling was added. So, one thing led to another and
I copied it into a local project. It does things a little different, in
that I made the fsk a dynamic library.
I also used the newer codec2 golay code, just to make sure on avoiding
the restricted licensing.
Then a strange thing happened (probably too much kool-aide) I rewrote
the kiss-fft to use c99 complex math. Many times I wanted to use
kiss-fft, but I didn't want to use a real/imaginary structure and
sin/cos. I just wanted to use complex exponents. I know it's probably
old age...
So, anyway, today after the BBQ, I came in to see if the last changes
would work, and presto I got the same packets as David did on his
original version.

Now all I need is a drone and a camera...
Thanks David and Brady for an interesting FSK project.
