I am currently exploring the multiple USRP Tx problem. I came across a thread from 2006 with someone working on similar problems... Has there been any progress on this? I don't want to duplicate any work.

Just copy the foo.rbf file to PREFIX/share/usrp/rev<N>/foo.rbf Eric _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
