[Commit-gnuradio] r6083 - gnuradio/trunk/gr-radio-astronomy/src/python

New Revision: 6083

Modified:
   gnuradio/trunk/gr-radio-astronomy/src/python/usrp_ra_receiver.py
Log:
Added GUI for post-detector offset and gain.  Previously these were carried
  on the command line only, as --calib_offset and --calib_coeff.  Now
  you can tweak them with the GUI, and the command line options have
  different scaling than previously.
