hi George, I noticed theses odd things several months ago. I am using USRP2s with XCVR2450. Since my UHD was upgraded to 003.004.000 or newer version, my USRP2s can't work in half duplex mode. When uhd_transmitter is instantiated later than uhd_receiver, tx works well but rx can't receive packets. When uhd_receiver is instantiated later than uhd_transmitter, rx could receive packets, but tx works with abnormal spectrum.
Now I have to use an old version (003.003.002) UHD. With this version, both tx and rx work well. So I doubt that there is a bug in version 003.004.xxx. Maybe Ettus can help us fix it.
