Thanks for that Hans,
My other two u3s both have park set to 2 and 15000000 so I just set this one the same when doing initial set up.
If I set to park mode 3 this turns park mode off between transmissions if I read it correctly. I'll try it and see. I have two u3s with the OCXO kit fitted so if it works I'll switch it off on both OCXO kits.
The universe is made up of Protons, Neutrons, Electrons but contains only one M0RON.
