Re: [Discuss-gnuradio] Scanoo_rx: New GUI, Center Freq Hopping & SSB Modulation

[madengr]

Mike, thanks for the detailed explanation.  Is there a reason for doing the
channel selection via FFT/IFFT method as opposed to a frequency xlating
filter?  Maybe it's more efficient since you needed to do the FFT anyway for
the spectrum sense.

I see the frequency selection with the mouse is a feature of the WX FFT sink
(Freq Set Varname).  I wonder if the same functionality is in the QT sink.

Anyway, yours is a good example to wrap my head around how the Probe Signals
work.  Looks like it may be a better method than the message queues I was
experimenting with.  I was using a queue to grab the FFT data and compute
the max value.

Thanks,
Lou
