if i have understand i need to use the --lo-offset of uhd_rx_cfile
i have gave various values to --lo-offset and only one value has moved the DC offset (--lo-offset=1G) and the plotfft gives many small spikes (maybe this is caused to aliasing, but i am not sure)
which is the rule (value of --lo-offset) to set the DC offset out of my band?
--lo-offset 1.0e6
