[Elecraft] 2 M Transverter Stabliization

[David Pratt]

Like you, John, I find the XV144 to be extremely stable after allowing a
few minutes for the oven to attain its operating temperature. I get the
correct offset without the need for any additional inductance to pull
the crystal.

A modification I have made though is to add a cooling fan similar to
that fitted to the XV432.  My XV144 is an early model, so I also drilled
vent holes in the top and bottom covers. I believe these are now
standard in later XV144 kits.
