The thread for QAM modulation is here:

The amateur radio digital television community is pretty fragmented right now with folks using DVB-S, DVB-S2, DVB-T, 64-QAM and ATSC. For bladeRF (also Ettus B2X0 and hackRF) we've tried to cover all the formats with at least a transmitter. DVB-T and ATSC also have GnuRadio receiver implementations, but the ATSC receiver requires a high-end CPU to achieve real-time decoding.
Here's the list of repositories:
https://github.com/BogdanDIA/gr-dvbt
https://github.com/argilo/gr-qam
https://github.com/drmpeg/gr-dvbs
https://github.com/drmpeg/gr-dvbs2
And a couple of utility repos:
https://github.com/argilo/sdr-examples
https://github.com/drmpeg/dtv-utils
ATSC is built in to GnuRadio. The updated ATSC receiver was released with GnuRadio 3.7.4, and resides in a new directory called gr-dtv.
There's a DATV (Digital Amateur Television) Yahoo group.

Clayton (argilo) VE3IRR has a nice blog entry about his DVB-T experiments.
