Hi!!
I'm trying to built a little radar with the USRP 2920 ..
but I have a problem.
I connect the two port of tghe USRP (TX1 RX2) with a low loss cable of 50 cm..
after transmitting a chirp signal, sometimes i found my signal on rx port shifted by 180 degrees .. totally reversed
it's possible that is a problem of the LNA on board of the USRP ?.

Ps
I Had this problem also with the USRP 1 of Ettus
