[Discuss-gnuradio] DVB-T/T2

With Rons help I got the DVB-T/T2 flowgraphs up and running.


DVB-T works great, no issues at all, while DVB-T2 is somehow flaky in reception.


When using a cheap DVB-x tester, the DVB-T2 constellation is phase shifted. I have no real world T2 signals to compare, but at least the tester shows normal constellation views when looking at S and T signals off the air.


This is how things look:




The flowgraphs are almost original, just adopted to the USRP B210, and I added channel slider...


Any ideas what I could tweak?
