Erik, I too have the 4.766GHz spur as described by Andrew. as purchased from R&L a couple months ago. The attached plot #1? is with a terminated input, Spur Removal? ON. No change with the external antenna. I don't see any other spurs. Plot #2 is the same with the Spur Removal OFF.

Can you check if you see similar spurs at 1069 MHz, 2138 MHz
and 4276 MHz?
I assumed these where solved but if you still see them I have
to do some more work.
