Hi all, I have to generate a narowband signal around 13.57MHz using LFTX/LFRX frontend (no LO), but don't want to use a high samplerate due to CPU constraints. I suppose the Interpolator + DUC/DDC on the FPGA can translate the narrow baseband to this center frequency, but I don't know to set the

Rensi, I have never run into this problem. What happens if you physically disconnect the USRP and boot the device? This has to be a driver problem as obviously GNURadio isn't running when your are just logging in. Sounds like a problem between the UHD drivers and the USB chipset. Boot in safe
