I have had several instances of nearby impulse damage and surge voltage
on the AC line. It could have been very expensive but for insurance.
I would put in a plug for either the ARRL or Ham Radio Insurance
Associates equipment insurance. HRIA will cover up to $5000 in losses
for $136/yr including Mechanical Breakdown. The two policies are very
different so review them to decide which is best for you.
If you love your K Line as much as I do, you'll get it insured.

I did computer repair in Florida. I had a time share/multitasking system in a
law office that had thousands of dollars in damage after the building next door
got hit.
The terminals were plugged into serial lines back to the central system. So
were the printers. (Think: 6 processor unix type system with a network inside
the box)
The tops of ICs were all over the guts of every printer, terminal and the computer let
out the magic smoke. ALL of the terminals and printers had been "unplugged" -
but not from the RS232 connections.
The ONLY way to isolate the rig is totally unplug the thing: antennas, power
supplies and so on... same with your computers.
Down in Florida, there are code required surge MOV's in every circuit breaker
panel. All they do is eliminate something close by. They get vaporized by a
direct hit.

Subject: [Elecraft] Unhook *ALL* connections before Lightning storm
Hi all, I work on K3's all day and would like to advise/remind folks
that lightning comes in through ANY path it pleases, not just the antenna.
Time and time again folks say they unhooked their antenna but the
lightning took out the DSL modem, computer and K3 via the RS232 port!
Anything connected is a potential path...
Be safe! '73
