Hi Thomas >> I am in the U.S.
Ok, that's the problem. In the US the 900 MHz band isn't used for GSM traffic it is an ISM band. The relevant bands are GSM-850 and GSM-1900 in the U.S. I've updated the corresponding page to give details of the different bands. http://273k.net/gsm/find-a-gsm-base-station-manually-using-a-usrp/ Robert _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
