What OS, version, distribution, architecture? Which version of the GNU Radio code? Are you feeding this with a signal generator? What's your input signal level? Which antenna port are you connected to? Have you tried running usrp2_fft.py? > If I try the lfrx or dbs daughter cards the set_center_freq response > appears incorrect.

Have you tried injecting a signal into the board and looking at it using usrp2_fft.py?
