Fw: [Elecraft] IO Problem

[Gregg R. Lengling]

> Then you have different serial ports (KIO's), the one in your QRP lid and 
> the one in the KPA100.  Sounds like the RS232 tranceiver in the KPA100 
> failed.  The RS232 is not used to talk to the KAT100 that is done with 
> auxbus functions that are on the same cable but different pins.  That's 
> why the wiring is different on the 2 plugs, with the auxbus plug going to 
> the KAT100 and the RS232 plug going to your computer.
