I don't know if this is a problem, but you're not checking for errors after any of the calls. This should be: r = ur.tune(0, r_subdev, 24e8) Eric _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
