Ok, I was supposing that.


So in the python code of the receiver I've put:


tr=uhd.tune_request(self._freq,self._offset)

self.uhd_usrp_source_0.set_center_freq(tr)


where freq and offset are passed as parameters. In this way I got no error.


Now, the question is: which values are good for "offset"? Hz? KHz? MHz?

I've tried small values, like 50 Hz, but nothing changes.

Is there a way  to find it?


I'm sorry, but really I have not idea

Thank you again for your support

You want to move the DC-anomaly right out of your passband, so choose an offset that's slightly more than half your sample rate.
