[Elecraft] Truth re. K2/100 freq drift?

[Tim and Nancy Logan]

Hi folks - 
My K2/100 seems to work just fine - outstanding as a matter of
fact....so I'm curious, what exactly are people experiencing regarding
frequency drift? Is it just on start up? Are you experiencing a
significant amount that affects practical operation or just measuring an
amount with lab equipment that most ops would never be aware of?
Comments from Eric or Wayne would be appreciated if you happen to be
reading. Thanks folks!
