When my KIO3 got zapped, I had everything disconnected. Antenna and all

disconnected was the RS-232 link between the laptop and the KIO3. Somehow
Even in Europe (east of the Rockies somewhat...). Got still 2 spares in

Ah, lightning. Whoever performs an analysis of the KIO3 failure mode after
being struck by lightning might have what's necessary for a very lucrative
