 self.update_grid()
  File "/usr/local/lib/python2.7/dist-packages/g
nuradio/wxgui/fft_window.py", line 401, in update_grid

    baseband_freq - sample_rate/2.0,
TypeError: unsupported operand type(s) for -: 'MyFrame' and 'float'

You have several tracebacks,  but perhaps fixing this one will
 give you a head start on the others. 




> Your variable baseband_freq is not a float,  but an instance of class MyFrame.  Perhaps you had intended to call a method of that class,  instead of using the class instance.
