So, to clarify, you have a SINGLE USRP1, a SINGLE RFX900?

You flow-graph uses two independant UHD sources, which won't work. You need a single UHD source, configured for two output channels, and use the dual-DDC mode to extract your two frequencies (which, by the way, are far enough apart that this will barely work).
