Hello,
I have a new USRP2 (no firmware upgrades), trying to run usrp2_fft.py with a decimation of 4. I can run higher decimation values (-d 8, -d 16) but -d 4 brings up the fft gui and shows no signal. Sometimes I get an 'S' but not always. I know using a BW of 25MHz is a lot of data, but was hoping to at least get the fft working. My computer is a Dell Optiplex 960 3.0GHz with 4G RAM. I am running Fedora Core 11. The on board GigE is Intel 82567LM-3. I tried ethtool -A eth0 rx on (to double check my flow control) with no luck. I have seen the chart: http://gnuradio.org/redmine/wiki/1/USRP2GigEReports and my next step is to get one of these cards and try it instead of my on-board NIC. But does anyone have other ideas? If you have successfully run usrp2_fft.py with -d4 can you please list your PC configurations/requirements? Thanks, all.
