I just went to the shack to actually check mine ... I was guess at the 5K1 from memory

Mine has 680R for R9 just like the Chinese diagram, I think most of the "normal" software is set up for 1K0 ... it is marked here on the upper row, second one in.

You may be aware of this already but there is a schematic diagram of the "black" ADF4351 boards. I found it on a Chinese and downloaded it. I have it and the one for the ADF5355 PCB on my website at:
I found that the topology and component numbering agrees with boards I have. Some of the component values deviate from the diagram. ;-)
