Hi Marcus,
I have tested downgrading UHD to 3.15 and it works ! (I’ve tried with
UHD 4.4 as well but its doesn’t work)
Now that the reception works everytime in a full-duplex communication,
I observe that the TX/Rx antenna creates a lot

I performed some tests with a spectrum analyser and a signal generator
as you have suggested and the problem seems to be in the RX side. Here
are the results :

Hi Marcus,
I have performed some tests physically looping TX/Rx to RX2 of the
same channel, and results are the same. I tried as well to turn off
and turn on the USRP between 2 consecutive tests, and It doesn’t seem
to change anything.
