Probably a signal magnitude issue then. Don't forget that UHD scales

you may need to
put a multiplier block right after the UHD source.

Have you tried setting the gain value higher also what antenna are you using? Nino ___ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
