Hi Martin,
I'm receiving a sat signal via USRP N210 interfaced to a pc with ubuntu.
Before when I run the usrp_spectrum_sense.py it shows the following output :
linux; GNU C++ version 4.8.2; Boost_105400; UHD_003.009.git-171-g51bc00ee
-- Opening a USRP2/N-Series device...

Using Volk machine: sse4_2_64_orc

Now some how the frequency does not change it printing the same frequency. (freq 1000460000.0)
So it seems the FFT not going to the right frequency so then I can't get the max power !
Thanks
