m...I suppose this is more repair than homebrew, but since at least it's in the
right spirit I hope you'll indulge me...

Took a lightning hit on the power line about a week ago. *The ham antennas
were disconnected so the ham gear survived, but some of my computer &
consumer gear wasn't so lucky.

Many PC Board designs incorporate 'thin' foil paths that are intentionally
used as fuses... *linking an input ground foil group to a power supply foil
group is one such usage. *The hit may have blown a trace that isn't
immediately visible.

I suffered the effects of a near by strike last year. *The induced field
blew out a myriad of low-level input circuits on everything from wireless
phones, to the 1000BT inputs on my server, and 24 port switch, monitors....
not the P.S., remote ant tuners, on and on... *Didn't loose a single power
supply or fuse. As a testament to ICOM engineering my IC-7800, at the time
connected to two antennas, suffered no damage. *My Elecraft K2, *connect to
a coax run that terminated at an outdoor antenna switch but was not
selected, came through OK too.

Lightning came do some pretty strange things to electronic equipment.
I once repaired a Radio Shack color computer that had 4 or 5 lines of
it data bus vaporized without damaging anything else. After the
damaged area was repaired with jumpers the computer worked fine. To me
the fact that the innards of this computer survived is as impressive
as the service panel that gets blown out of the wall and across the
room or the tree that is completely stripped of bark. The damage was
done directly beneath the uP chip.
