Yes - that's it, operator error, -20 to 0 gets peaks at 40 to 300. Interestingly, if you set it back to 255 with self.usrp._write_9862(0,16,255) you get a signal at peak 500. 500 is 4.4db over 300, not quite the 5.5 extra of 25.5 over 20.0, but it's there. usrp_siggen.py from examples (inadventantly?) uses 255 since it doesn't set_pga(). Anyway, that anomaly doesn't explain the missing output - back to Sherlock mode. --Chuck _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
