Hi Marc, How much leakage are you seeing between TX and RX on a WBX board?
Yeah, GRC works fine for full duplex and it is very easy to set it up.

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. -Marc _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
