[Elecraft] K3 Drift

[Harry Yingst via Elecraft]

Nearly all radios have some drift.
You can minimize it by leaving the radio on or allowing it to be on a while before using it.The high stability option does make it better and a GPSDO will essentially eliminate it.

Drift is most pronounced in the digital modes and in the upper bands.
Another culprit is having a cold shack in wintertime, the initialturn on until warm-up can show a fair amount of thermal drift

KV6X has noticed his temperature controlled crystal is drifting in his K3.
I notice it too. This is a new thing. I have never seen a post about K3
drift. Anyone had this problem??
