Hi, The experiments with mode 6000 are going pretty well. Another local HAM (PE1ITR) even managed to work our repeater with just a HackRF. Compared to analog FM it seems to perform pretty well.
But I would like to take it a bit further and try to introduce some FEC. Since the currently used codec2 mode only needs 3200bps there is still plenty of room. I was thinking about a rate 2/3 code (687 code bits for 458 data bits), but I am a bit puzzled with the ldpc octave code. How exactly do I generate the needed matrix (and ofcourse the C and header files)?
