Yes - that's it, operator error, -20 to 0 gets peaks at 40 to 300.

Interestingly, if you set it back to 255 with


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.
