Re: [Discuss-gnuradio] FW: LFRX Board as Audio analyzer

[Matt Ettus]

You need to turn off DC offset correction.  DC offset correction results in a narrow spectral hole around DC.

Hi,

I am trying to do some audio analyzing with the usrp and lfrx board which claims to be dc-to 30mhz.
However it seems that the frequency response form  dc to let say 100hz is not flat (lacks)

I have set the USRP source on 0Hz..

Is this just a fact or am I doing something wrong.
