Decoding FFSK ?
Decoding FFSK ?
I've noticed a local group are using some kind of FFSK on the end of their transmissions,
From what i can find its a 1200bps system, heres some info; http://warps.com.au/what_is_warps.pdf
My question is, has anyone used some software to decode such data before?
I would be interested to know if i could get my hands on some to test and attempt to decode
Cheers

Perfect candidate for GNUradio companion. Even has built in FSK blocks and scope sinks to help you out

Have you considered trying any of the Amateur Radio APRS (Automatic Position Reporting System) software.astro_boy wrote: . . My question is, has anyone used some software to decode such data before?

Gnuradio looks really in depth! maybe im getting myself into something way beyond what i can understand.
As for the APRS, no i didn't think about that.
I'll have to see if there are any programs that might do what im after.
