[Elecraft] K3 ref osc calibration question

[Andrew Moore]

I'm performing a calibration on my K3's TXCO (5 ppm version).
K3 is new/recent build, serial 44xx

K3 owner's manual, Rev. L, page 49.
"Method 2 (zero-beating)"

I'm using an Elecraft XG2 signal generator at roughly 14.060 MHz

Procedure says to enter CW mode and tune to the specified frequency (in this
case, I don't know it, as every XG2 is probably a little different)

Since I don't know the exact frequency, can I spot it with the Spot
function, and then proceed to the REF CAL adjustment?  Or is there a catch
22 here, as the spot function may not be accurate until the TXCO is
calibrated?
