Re: [Discuss-gnuradio] Probe Avg Mag^2 - Display/Store values

[Cinaed Simson]

The fragment of the flowchart you sent was for a USRP.

For the HackRF, you need to use the Osmocom Source.

See the HackRF tutorials at

  https://greatscottgadgets.com/sdr/

which should get your started with Gnuradio and the HackRF.

And then the Gnuradio tutorials at

  https://wiki.gnuradio.org/index.php/Tutorials

for advance topics.

The bottom line is you can only calculate the relative power - see the
FAQ at
