The gr-dvbt2 DVB-T2 transmitter has now been tested with a real receiver  
(a PCTV 292e USB stick). The BBC 32K/256QAM mode works fine on  
bladeRF (40.2 Mbps in an 8 MHz channel). CPU usage is about 60%  
on all four cores of an Intel E5-1607.

I’ve added links to test streams in the README for others to test with  
(including a 4K/64QAM stream that requires less CPU).
