We are using the latest stable gnuradio (3.1) code by check out using the following command: ( as given in the Build Guide) svn co http://gnuradio.org/svn/gnuradio/branches/releases/3.1 gnuradio
We are running it on Fedora Core 7 (fc7) with kernel version 2.6.21-1 (2.6.21-1.3194.fc7 ). We varied the rx-gain to different values and 90 being the highest, but that did not help much ! We can generate signal and receive it using usrp_fft.py script, but benchmark_rx.py is not receiving it. We also tried changing the distance between two USRP boards between 1 and 3 m, even that did not fetch anything. Please provide your inputs if you can figure out what could be going wrong. Thanks, Ashwin.
