Re: [Discuss-gnuradio] USRP network based spectrum analyzer

Thanks Marcus! I took your idea and ran with it but encountered a funny issue. I'm slightly confused about the output of the logpwrfft (which is giving me the output of gr_fft_vcc). I've been assuming that logpwrfft returns a vector of amplitudes in dB for each fft bin. Lets say my fft siz

I have a usrp and computer in a remote location without much network bandwidth available to the system and I'm using it as a spectrum analyzer. I'd like to run the fft on the remote system and then send the results to a connected client for display. This would allow me to get greater fidelity tha
