It _is_ intended:
So forget about my question :)
Hmm, now I see, there is an option "constellation rotation" in the modulator block. Maybe this is not an accident, but wanted behavior?! I will check this evening...
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?
