[Elecraft] Static Discharge Through K-Pod

Greetings, All!

I'm getting static electricity shocks through my K-Pod case, and I need
some suggestions for mitigation.

Background:  I keep my K-Pod on my operating desk just to the right of the
shack computer mouse. I've noticed when I walk over to the desk and grab
the mouse, the K-Pod will beep.  Further investigation shows I'm getting
static electricity discharge from my finger through the K-Pod, this morning
I even noticed an arc from my pinky finger to the K-Pod case. When the
K-Pod beeps, the D1 and D2 lights will cycle.

The shack is carpeted, and I have a rolling chair on one of those plastic
chair mats (which can probably go away if necessary,) I suspect that mat is
probably contributing to the static problem.

Obviously, I don't want static electricity discharging through my K-Pod and
then through my K3. I'd welcome any ideas for static mitigation
strategies.  I was thinking some sort of grounded mouse/keyboard mat, which
used to be more common, but seem hard to find these days.
