Some lightning musings....
My K3s network interface board took a surge on the USB part of the board
a few years ago and toasted a diode and maybe a transistor (I forgot),
RS232 was unaffected. Elecraft replaced the board and returned the old
one. One of my to-do list items is to replace those components. My
primary radio is now a TS-890 but the K3s is on duty for JS8Call 7x24
(when no storms are forecast.) Still salivating over a K4 BTW.
As far as lightning, one of my most unusual personal experiences was
when we had a sailboat (40' ketch with the mainmast 50' off the water)
at a typical Florida marina. Next to us was about a 35 or 40 foot
powerboat and next to him was another sailboat. So one would expect the
powerboat is protected by virtue of the two tall lightning 'rods' on
either side of him.
Uh, no. We had a very close lightning strike, none of our electronics
were damaged and the other sailboat was also unaffected. The powerboat's
electronics were toast, all of them. He couldn't believe it nor could
we. We suspect he took an electrical surge via the shore power cord but
that's just a wild guess. We heard of sailboat that took a strike and
the next morning when they started the engine they discovered the
transmission was internally fused together .
