I'm not sure I understand correctly what you mean. You mean that the result for a given frequency was not stable in your case across many measurements? In our case this situation was repeating, but the application doing the recording was restarted for each measurement. > As far as I remember the issue was because we were not using the > LO-Sharing.

GNU Radio didn't configure LO-Sharing the way it was specified? -- Best Regards, Piotr Krysik _______________________________________________ USRP-users mailing list USRP-users@lists.ettus.com http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com
