Don,

Yes, you should be concerned for the health of your K1.  If you have the
KAT1 installed, the wattmeter diodes can be zapped by a charge like
that.  Use a resistor between the antenna and the counterpoise and if
you can find a way to ground the K1 case, that would be good too.  It
does not need to be a wonderful ground, but even a 1 foot rod into the
earth will help bleed off the static charge.

The charge is most likely coming from "wind static" - there does not
have to be much breeze to create it.
