What does your test setup look like? Are you using USRP1? USRP2? USRP-N210? Using UHD? Are you tests over-the-air or with cables? Are you using attenuators in the cabling? -- Principal Investigator Shirleys Bay Radio Astronomy Consortium http://www.sbrac.org _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
