Hi, not having access to my setup for now but for the beginning you could try recording the spectrum with your USRP and then use the file source to decode the signal offline. There is a script file apps/capture.sh that I usually use to capture data. You may tweak it for your needs (frequency, gain).
Sometimes it was reported that on old cpus the processing power is not enough so that the result is an overflow (you directly see a long OOO message in this case). Try to see if this is the case.
One way to reduce the overhead is to run the receiving flow directly from command
line instead of gnuradio-companion (e.g. ./top_block > out.txt) after you have generated the flowgraph. The gnuradio-companion cannot cope with big amount of data when the blocks gets out a lot of
text.

Hi all,
I am using ubuntu 13.04, GNURADIO 3.7.
I cannot transmit or receive using two (USRPN200 + XCRV2450 d.board+VERT2450 antennas) devices for DVB-T project.
Here is the dvb-t project:

It will be very helpful and appreciated if you help me. If someone tested it or can do it, please let me know. As far as I know someone tested it with N210 model.
I think this failure is due to high noise/interference or smt. else. However I tested it already with all possible configurations. I also attach my .grc files.
