linux; GNU C++ version 4.6.3; Boost_104601; UHD_003.006.002-rc2

Going through GMR mailing list I have found that you posted same problem in Oct-2012.

I have follow the Mr,Sylvain advice and run uhd_fft utility, that is working fine and showing signal on screen.


Can u plz guide me how to resolve this issue.
(i am using Ubuntu 12.04 OS).

Thanxs
