I understand that this can be done, by an external clock (GPS diciplined OCXO), with the 10Mhz and 1PPS inputs. is there any way I can tell the two usrp2's to start together, instead of using the timestamps to synchronize them? -- View this message in context: http://old.nabble.com/synchronizing

Dear List, I was trying to implement some LAPACK/BLAS(liblapack as included in Ubuntu) wrappers for GNURadio since I haven't found anything to do matrix/vector operations in GNURadio but I haven't found out how to do a clever conversion from Fortran's (more precise the f2c) way of dealing with com
