[Elecraft] [K1] VFO Drift Problem

[Michael Babineau]

Very interesting problem Matt.  The VFO in my K1 is stable once it has warmed up for about 5 minutes,
as long as the rig isn't out in the sun.  I have observed some significant drifting due to physical warming
while operating portable so I now know to keep it shaded.

Sometimes I wish for a K1.5 with a DDS VFO as my KX1 is rock solid from -25C to +30C (and yes I have operated portable in those condtions ;-) ) .
