What would be useful is for oscope is to have the X axis scaled according to 
the actual viewed frequency, not the frequency after downconversion.  This 
would be the same as the fft program displaying in -X to X MHz instead of 
showing the acutal tuned frequency on the axis.

In other words, make oscope look like a real oscilloscope display rather than 
the downconverted display now.  I have some other ideas; I need to look at 
QtDSO (which works with the Velleman PCS64i) and see what would be required 
to do the same with the USRP code.
