Although the XCVR2450 doesn't do full duplex, the WBX does, and current UHD avoids the problem I described in my previous message. However, the WBX has enough internal leakage between tx and rx that we gave up on single-daughterboard full duplex. We now use a USRP2 with a WBX for tx and a USRP N210 with a DBSRX2 for rx.
As for examples, I'll try to clean up my C++ app and post it later this week. GRC works fine full-duplex, too, I believe.
