I'll have to take another poke, I guess.  This has happened since I installed
  gnuradio (or perhaps wxPython--they were done at the same time).

It doesn't seem to matter whether I'm actively running a gnuradio app or not.

In other matters, I managed to get dbs_debug.py running, after changing the
  config on libfftw3--as you suggested.

The dbs_debug app always returns "could not lock" when changing frequency on
  the DBS daughterboard--my supposition is that the frequency-setter isn't
  waiting long enough for the "PLL locked" bit to come back before concluding
  that it isn't locked.  On a fast CPU, the PLL could take (relatively) and
  *eternity* to indicate lock.

Also, in dbs_debug, I found that keeping the scope_sink window around caused
  the application GUI to lock up as soon as the scope_sink window showed
  anything, so I took it out, leaving only the FFT display.

Now, if I can only find my SMA-to-other-stuff collection, I'll get the DBS_RX
  hooked up to a feedhorn, and see if I can see the GPS L1 signal :-) !!!
