I strongly recommend doing the temperature compensation. On 6 meters 
this will leave you something like just +/- 3 Hz of "hunting."

------------------
I have run tests on 6m at 5w simulating JT65 operation:
Before doing the Temp Comp drift was up to 54-Hz
After it was a couple Hz as Wayne stated.  My test shows a big "bump" 
in the drift curves which I suspect is a bad temp point in the 
compensation process.  I will repeat Temp Comp to see it this 
artifact disappears.

I have not tested at 2m.
