You might also try playing with kalibrate http://thre.at/kalibrate it will scan for GSM base stations and use the results to determine the current local frequency error in your USRP. If you have an independent means of determining this error frequency, and compare this with the results of kalibrate, it would pretty much nail the identification question.
Some tips 1) The proper USRP / DBSRX gain setting is important 2) The gain setting and the frequency error may change if you move to a different frequency band... 3) You have to manually specify the proper USRP clock frequency to kalibrate (unless you've modified the hardware clock) Max _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
