[Elecraft] The KIO2 unit in my K2 has died

[Clark Macaulay]

Hi, Paul.

I had the same problem a few years back.  Unless you can see a carbon trace
somewhere, it's likely to be the diodes or the microprocessor.  I replaced
the microprocessor purchased from Elecraft and that fixed it.  You may want
to try snipping and replacing the diodes, first.  I purchased two
microprocessors just in case it ever happened again: my K2 is the QRP radio
for the station with connection to logging software.  The K3 was
untouched.

As I recall, the lightning strike took out the uVerse modem and a board in
my PC.  After that, I changed to using WiFi for the PC instead of a cable
just to eliminate one path for future lightning strokes.
