If you run a uhd_fft.py, tuned to the correct frequency, do you receive
a spectral plot that looks
“reasonable” ?

answer to marcus:
yes the spectral plot is reasonable, but still have no sound.
thanks

I spent pretty much all day yesterday trying to tune FM on an N210, I
get peaks where I’m expecting stations but just silence.

Have you tried setting the gain value higher also what antenna are you
using?

Probably a signal magnitude issue then. Don’t forget that UHD scales
everything into
{-1.0,1.0}. If you’ve adapted some of the “classic” examples to UHD,
you may need to
put a multiplier block right after the UHD source.
