[Elecraft] K3EXREF Query

[David G4DMP]

I have not seen any replies to this, Brian.

As I see it, the only way out is to go into REF CAL from the Config menu
and then press 2 to disable XREF until the frequency standard has
locked.

Like you, I have found that if XREF is enabled when the K3 is switched
on, the K3 drifts unacceptably for 15 minutes until the frequency
standard has settled down.
