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... -- Current recv frame size: 1472 bytes -- Current send frame size: 1472 bytes Using Volk machine: sse4_2_64_orc gain = 19.0 2015-06-02 03:18:27.149244 center_freq 1000775000.0 freq *1000468750.0* power_db 5.58520464401 noise_floor_db -72.1895763839 2015-06-02 03:18:27.149282 center_freq 1000775000.0 freq *1000475000.0* power_db 6.39925714799 noise_floor_db -72.1895763839 2015-06-02 03:18:27.149342 center_freq 1000775000.0 freq *1000481250.0* power_db 11.4556676649 noise_floor_db -72.1895763839 2015-06-02 03:18:27.149409 center_freq 1000775000.0 freq *1000487500.0* power_db *14.7902792949* noise_floor_db -72.1895763839 2015-06-02 03:18:27.149454 center_freq 1000775000.0 freq *1000493750.0* power_db 13.7591168304 noise_floor_db -72.1895763839 2015-06-02 03:18:27.149492 center_freq 1000775000.0 freq *1000500000.0* power_db 9.48612353831 noise_floor_db -72.1895763839 2015-06-02 03:18:27.149531 center_freq 1000775000.0 freq *1000506250.0* power_db 5.03300407511 noise_floor_db - 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 !
