Hi all,
I ran into this on radioreference - might be of interest to people on here. it is a discriminator based decoder for P25 (phase and 2) and it seems to support DSTAR as well. Runs under Linux/BSD.
Use at your own risk

My sound device under Ubuntu is actually /dev/dsp (not /dev/audio)
DSD decoded the P25 frames and displayed the frame data fine after that (though the BER was pretty high)

Just wondering what sort of transmissions here in oz such a program would be useful for, couldnt tell whether it was simply a software based scanner for unencrypted digital transmissions or if it does more then that..
