Mike,
As the instructions indicate, you only have to do it once.
That is for initial aging of the crystal.
If you are getting only 1 Hz drift on 40 meters, note that the frequency
stability spec for the KX3 is +/- 1 ppm for a temperature range of 0 to
50 degC. So you may not be able to do a lot better, much depends on the
temperature range inside the enclosure.
If you are running it at more than 5 watts, you might do well to invest
in an aftermarket heatsink.

Hello Elecraft !
I want to run the KX3 Extended VFO Temperature Compensation procedure again
as I still get +/- 1 drift on 40 meters wspr. The instructions say: "If
using the Elecraft XG50 *for the first time*, an 8 hour power-on aging
cycle is recommended but not required." I did this the first time I ran the
procedure.
Q: Is the 8 hr warm up recommended *every* time you run the procedure? Or
was that just once, for the new XG50?
