We may not know the tune but the encore is sad and familiar: The cost to
repair the damage is equal to the deductible on your homeowner's insurance
policy. "Ask me how I know."

Indeed there IS rhyme and reason, but some of us haven't learned the
tune! :)

I had a weird thing happen with my K3 this morning. I tried to check into a

Thanks for an interesting thread, which elicited some good technical replies as
well as some undeserved and rather haughty tut-tutting, presumably about

Jorge,
In short, no. As has been stated repeatedly lightning protection is the
responsibility of the owner, not the radio vendor.
Can we move on to other topics please?

Asked, answered (no, there isn't a more robust device); it's up to the
station owner/designer to protect the station, not a manufacturer.
Let's move on please.

After a lightning strike took out my shack computer, all of the Ethernet

John,
Remember the "Cone of Silence" in the old TV show Get Smart... There is
a "Cone of Protection" for lightening, although it was not as funny as
the "Cone of Silence" was... See:

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
Lightning is like wildfires which burn some houses or land but not
others. There is no rhyme or reason why some devices are not damaged
and other are. I suspect that most items were damaged but not made
inoperable.
Couldn't the argument be made that the computer or USB hub should do

Since there is zero voltage measured
on either terminal 1 or 2 of transformer

there. It could be that RFC4 is now open.
Keep tracing the voltage along that +12V
rail back to the point where it supplies
