DBSRX and USRP2

Hi,

I am using USRP2 and DBSRX board to receive 2.23 GHz signal. I am using
GRC
blocks USRP2 source connected to the FFT sink.

I have modified the DBSRX board as mentioned on the wiki (removing
resistor
from R193 and soldering it to R194). But still I don’t receive any
signal at
any frequency. All I see is the noise floor of the device itself.

Can someone please advise?

Thanks in advance,
Amee
