[Elecraft] VFO Drifts during Transmit

[Glenn Maclean]

Hi I have had my K2 for about 2 and1/2 years now. It has worked to
perfection up until today. I was having a CW QSO on 20 meters this
afternoon. My VFO started drifting un commanded during transmit. Yes the RIT
and XIT were off. I cycled the power on and off. The VFO was stable again.
Then after about 10 minutes after cycling the power back on the VFO started
drifting again during transmit. I can watch the numbers in the VFO display
change as I transmit.

Where do I start looking?
