[Elecraft] Improved KIO3A Immunity to EMP

[VE3GNO Daniel]

Hi 
I tried to use serial port isolator with 5 wires to get better lightning protection. I have 5 of these

with 5 wires dc separation. With my FT5K worked fine but for some reason with K3 is not working. I should investigate closer the root cause, maybe levels or maybe something else, that sounds like a plan for the next "electrostatic" season. THe idea to get separation on serial port makes me feel safer when comes to lightning.

Is this problem on anyone's radar screen at Elecraft?  We're in 
lightning season again, and while I've done everything I can think of, I 
live in fear of another U1 failure.
