[Elecraft] K2 frequency error/drift figures

[Bob Lewis (AA4PB)]

The one variable that is rather difficult to control in comparison
between rigs is ambient temperature. Things like heating/ac
conditioning systems cycling, the amount of air flow around the K2,
etc. could all have an affect on the overall stability. The frequency
error I suspect may vary from rig to rig according to the resolution
of the CAL function. It will be different depending upon which part of
a band you are tuned to and probably from band to band.

It would be interesting if someone could run on in a temperature
chamber and see how it varies with temperature.
