If the K3EXREF is left unconnected to an external frequency reference, it should not affect any calibrations. If it is connected to a ref oscillator, it would affect your reference freq calibration - in that you wouldn't really need to do it at all.
I would go without it until you get the basic radio together, just the same. "Should not" isn't that same as "won't". I was one of the Field Testers for the ref board, and I went through the process both ways: as a "new build", and again as an add-on. Neither of them was affected by the presence of the ref board. Others may have differing opinions. 73, matt W6NIA On Sat, 13 Oct 2012 10:56:05 -0700 (PDT), you wrote: >I'm building my second K3 with the K3EXREF option and I wonder if anyone can >tell me if it would be a problem to install the K3EXREF during initial >construction, at the same time as the KREF3.
