My neighbor in high school worked on lightning arrestors for GE. I’m still sad
that I never asked to visit his lab.

Hi Bill,
No issue with that. In my mind though there is a big difference
between "surge" and "strike". These may have protected some guys stations

That indicates you either have a faulty 3,5 mm socket on the KIO3 or
maybe not the right plug (US vs. mm diameter, there was a discussion
about that a while back). The latter might well be the case as you

I disagree. While the bonding and grounding recommended as standard sound

I've had this happen a number of times after I've unplugged the serial
cable. Hasn't happened in a while though. The only way to fix it is
what you did, remove one of the batteries.

The alternative to disconnecting everything is to design your ham
station to tolerate lightning events.
There was a very good 3 part series in QST for June, July and August of
2002 that dealt with the design of a station for lightning protection.

The question is "how long are they?" - Ethernet cables are typically 6-20 feet
long. A jumper between the rig and amplifier, much shorter.
Length determines how well it acts as an antenna. The cables I worked with
were perhaps 20-50 feet long, and made good antennas. Some of the ethernet

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.
And another warning: Nearby (like next door) lightning will be picked up by
ANY long wires which end up acting as antennas.
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.
