A couple of things.
1) If you're capturing at 10 Msps, you need to resample to the DVB-T
sample rate of 9.142857 Msps. You can do that with a rational resampler
block set to interpolation = 64 and decimation = 70.
2) That's not a very good signal. It has a lot of multipath and poor SNR.

Hello,
Once again I am asking for some help with the DVB-T functionality of GNU
radio.
I am using complex binary files recorded with a USRP at 10 Ms/s. The DVB-T
rx example chain can't decode it at all. I have changed every setting
according to Hungarian transmit parameters (64QAM, 1/4 GI, 3/4 co
Thanks everybody for all the suggestion!
I think that modyfing an audio card it's the cheapest and more-than-enough
solution at the moment ;-)
