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 of interferences to the
RX2 antenna in the same channel.
For examples, I tested sending :
*
1 sin signal of 50KHZ from channel 0 to channel 1, at center freq 1GHz
*
1 sin signal of 80KHZ from channel 1 to channel 0, at center freq 2GHz
The result is available in the picture attached (the green circles are
the carriers received, the red circles are the interferences caused by
the TX) . Is this a normal behaviour ? Is there any
configuration/customization that can be applied to attenuate those
interfereances ?
Thanks again for your support, it is really appreciated.

The center frequency labels on your QT GUI frequency sinks aren't
consistent with what the source is actually tuned to.
