Getting FM radio signal strength

GNU Radio

Is there any way I can the signal strength from a radio station that it
is
tuning into? I am trying to implement a scan mode so I can get all the
FM
stations.

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,

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
