Re: [Discuss-gnuradio] Is that possible combining usrp_fft.py and usrp_spectrum_sense.py to do spectrum analysis and observe in GUI in a wider frequency range?

[Brook Lin]

I have figured out why it failed to set freq. Now my question is still how
can I get one GUI with one plot and show all the spectrum, say all FM
stations.

Thanks
