Help :Usrp2_fft.py fails to gives the correct output

Hi Eric ,
We here have just got introduced with gnuradio and are seeking support
on
few problems with usrp2 .

We are unable to get the correct output of usrp2_fft.py after
installation and upgrading to 11370s (fpga and s/w) . No carrier freq
seen
only noise at ~ -100 dB for different values of decimation , gain and
few
fft sizes.

We tried the following command under two paths -

/usr/local/bin

with root permissions

./usrp2_fft.py -f 20M -d 8 -g 1 --fft-size 1024

we tried decimations 4,16,32,50; gain 0,1,10,20 and fft-size
512,1024,8192

/home/gnu1/gnuradio/gr-utils/src/python

./usrp2_fft.py -f 20M -d 8 -g 1 --fft-size 1024

we tried decimations 4,16,32,50; gain 0,1,10,20 and fft-size
512,1024,8192

We have also applied all suggestions on forums to see if it works ,
unfortunately without any success
