HI all… 

My K3 suffered some EMP damage from a recent T storm… I’ve found L4 on the KIO3 
remote IO board open with evidence of heating on it….not sure what else may 
have been nuked.

If I turn on the radio with the KIO3 in  the radio boots up but then switches 
between TX and RX about 1/ sec … everything else seems normal.
If I try to connect via RS232 it just goes into TX … 

If I pull the board all appears functionally normal.

Has anyone experienced this similar issue when the IO gets damaged?

Does anyone have a spare KIO3 board that they may have pulled and saved when 
upgrading to the USB IO set up, or any suggestions as to what else may be 
damaged , like U1 ?

Thanks in advance
