Hi Pep. I am using the djx11 in I/Q mode with fcdp-tetra_demod.py. I leave sample rate @ 96000 but low-pass filter (-L) 12.5Khz (gr firdes lp filter in complex gives + - 12.5khz = bandwidth of 25khz). this gives me excellent constellation and works fine on demod. I hope this helps. Regards. Graham.
