The gain settings were 0 for tx and rx and the attenuation was 10dB. I
increased the gain values but I still had the same problem.
Thanks!

What type of daughtercard do you have?
How are you setting the frequency?
Try increasing the RX gain only.
How are you detecting the signal on the RX end?

Hi there,
My name is Maria and I am contacting you as I have a really strange
problem when I try to use the tx and rx of my USRP X310 at the same
time to tx a simple CW signal at 3.5GHz and receive the same CW
signal at the rx (an attenuator is connected between the two ports).
The problem is that no signal is received, just noise. I know the
two USRP blocks are working since if I do not change anything from
the gnu radio script and I just connect the rx to a signal generator
and the tx to a signal analyser, I can visualize the proper signal
on GNU radio and on the spectrum analyser. Is there anything else I
need to take into account when the two ports are connected to each
other?
Thank you very much in advance.
Best regards,
Maria Jesus
What gain settings are you using on the TX and RX? How much
attenuation?
