I've had quite a few problems which I think are caused by poor phase noise on the XCVR2450 -- it's an all in one chip with a local oscillator on board etc - the 2400 appears quite a bit better (20dB if I remember correctly!)
The schematics are in an odd place for this board - I could only find a link under the USRP1 page http://gnuradio.org/trac/attachment/wiki/USRP/xcvr2450_rev1.1.pdf Tim On Tue, Oct 27, 2009 at 6:41 AM, N.
