There was a post to this maillist over a year ago which said
that the most frequent casualty of lightning strikes in the K3S
was the USB chip and associated circuitry. The recommended "fix"
was to unplug the USB cable from the back of the radio when it
was not in use.
Applying this fix to a remote station is an interesting
exersize. I think a 4 poll relay that grounds the connections to
the radio while letting the bus float might be the best
solution. It could be activated by the 12V output from the radio.

I posted a note yesterday that I took a power surge which
knocked out my PC and couldn’t connect to my K3S. Thanks to
all the input for you guys, it would appear that the IO board
on the K3S got fried. Still to be confirmed, but strongly
suspect true.
