[Elecraft] Lightning protection.

[Dave Baxter]

FYI.

RS232 (and other serial link type) LEMP (Lightning Electro Magnetic Pulse)
surge protectors are available from several vendors, and not that
expensive, compared to the cost of a rig, or top range PC.

Often wonder why (other than expence) fibre optic links are not used.  CAT
& audio over a LAN or USB FO link?

Would help general EMC issues too.
