[Elecraft] Static Discharge Through K-Pod

There has been very low humidity this week, and I have had some shocks at
home.

When we got lots of static discharge shocks after walking on my
mother-in-law's carpet, I put some 1 Meg Ohm resistors under the light
switch cover screw for her to touch in the winter before the switch.  Silly
idea but it worked to discharge all the static but so slowly as to not
experience the shock.  There might be a similar solution to touching the
K-Pod.

My K-Pod arrived today, and my only annoyance is that the cables are too
short for both the radio line and the 12v line.
