[Elecraft] Unhook *ALL* connections before Lightning storm

This sounds like good advice.  However, every connector socket on my K3 
is populated, ditto the computer, ditto the KPA500, ditto the KAT500.

Pulling all wires when there is a potential storm threat is totally 
impractical.  Even if I did, I'm sure some of the connectors would 
simply not last.

I suspect others have similar situations.
