I believe that this grc file has suffered bit rot due to new developments in the code, specifically gr-digital component.

Its often very nice to make a simple GRC app that sends and receives a test tone. Be careful if you plan to loopback TX into RX port on the daughterboard. Use low gain and lots of attenuation! -josh _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
