Re: [Discuss-gnuradio] [USRP-users] getting noise for FM receiver with usrp e110 ?

[Mike Jameson]

The SBX has a frequency range of 400MHz to 4.4GHZ which is why you cannot tune to broadcast FM stations between 88-108MHz:

Hi everybody,

I'm trying to implement FM receiver on usrp e110. The daugtherboard used is SBX Board Rev 5.1.

As a result, I got only noise, I wasn't able to hear the local station at 103.5 Mhz.

And I got this error:

UHD Warning:

    The hardware does not support the requested RX frequency:

    Target frequency: 103.500000 MHz

    Actual frequency: 423.500000 MHz

>>> gr_fir_ccf: using armv7_a

>>> gr_fir_fff: using armv7_a

I attached a screenshot of FM receiver 's GRC.

Can you help me to detect if there are some parameters which are wrong ? 

Best regards,
