[Elecraft] KX3 freq stability module request

[Brendon Whateley]

No the temperature calibration is not done at the factory.  You basically put the radio in the fridge/freezer and then go through  process with an accurate reference signal to correct for drift as the temperature comes up.  It is only needed if you have need of very tight frequency control -- as is required by some digital modes.

near the bottom, you can see the application note.
