Hey SWL - markro92 ,
I'm now playing around with VCM/ACM, does your software support it?
I've created a basic sample using GnuRadio and DVB-S2 VCM module (https://github.com/drmpeg/gr-dvbs2).
After required conversion from fp32 to int16, it looks as the app correctly finds the modcod, but does not always recognize pilots (they're on) and correct roll-off (0.2).
Also, no output to file and the constellation looks 'combined'.
