ADF4351 control wiring

[g8gtz]

There's a comment been posted on the UK microwave group about the Radcom article on Page 72 in the June issue.

I hope you all notice that that the control bus from the Arduino to the ADF4351 does NOT use
a nice twisted set of wires unlike the power supply.
I found out the painful way that twisting the control bus wires will guarantee it wont work!

Just to be aware - it may apply to the Portsdown as well....
