Actually, it looks like it doesn't. It messes things up when I call it from my Mac, but on my ubuntu machine it just has no effect. I'll just ignore it for now. OS issues are the plague of my project right now. Thanks again, Morgan On Fri, Jun 10, 2011 at 3:40 PM, Tom Rondeau wrote: > On Fri, J

When I switched to Ubuntu the majority of my problems went away. I've got no idea what was going on with the Windows machine, but I never got any erro

Hi Everyone, I've been playing around with GNURadio and a couple of USRPs lately, but I've run into some problems. I'm using a modified version of the benchmark_ofdm_tx.py and benchmark_ofdm_rx.py scripts. I updated them to use uhd, and I'm using them with two N210s. Each N210 has a WBX daughterbo
