[Discuss-gnuradio] RFX900 MIMO on old usrp, gives failed to set frequency

[Martin Dvh]

Hi all,
I am trying to use an RFX900 MIMO on an old usrp board (rev 3 serial 309)
this doesn't seem to work.
(Failed to set frequency)

when I try it on a rev 4.1 board all works fine.

Are the old rev 3 usrps not able to supply the 64 Mhz to the RFX or is there 
some other problem?

Greetings,
Martin
