Re: [Discuss-gnuradio] getting FM radio signal strength

[ish13]

Ok I will look into that. Another question... I am not sure if you have seen
the code for the usrp_wfm_rcv.py code but in the code there is a little
section where it builds a FFT plot and displays the date.  Do you know if
there is anyway of getting the data that it is plotting?  

Thanks

Hi ish13,

this is one of the most commonly asked questions on this mailing list.
There is no simple way to get the absolute received power from the
sample values.
Try sticking to estimating SNR.

Have fun,
