[Elecraft] New K2 problem ?ATU

[Byron N6NUL]

I would suspect water in the feed line or a bad connector first. You'll know more  when you can inspect the antenna.

You could try overriding the tuning power (in the manual) and see if it can even tune at full power instead of the normal 20 watts. I suspect it would have an issue that the lower power doesn't reveal.
