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.

Subject: [Elecraft] IO Problem
I have an unusual problem may some one can help with
My K2/100 has stopped talking to my computer.
I have tried 2 computers thinking it was the serial port but no
I redid the cable and still nothing
Finally I changed the amp lid with the QRP lid and it all works fine.
I have a KAT 100 tuner as well and the rig does talk to the tuner and
everything on the amp and tuner works. ie power, tune, antenna switching.
The rig just doesnt talk to the computer. Like I said it works with the
IO on the qrp lid and the settings on the computers are correct and the IO
is on on both the KIO and the K100
Any thoughts
