Tom,
The suggestion from Jim Brown was to replace the cable to the computer
with twisted pair cable (CAT-5 will do, but shielded twisted pair is
better) Both RXD and TXD should be paired with a conductor going to pin
5 (Signal Ground).
If you do not have a computer connected, the computer cable (the RS-232
part of the AUX I/O) is NOT your problem.
The AUX I/O signals between the K2 and the KAT100 are usually not a problem.
Is the KPA100 mounted on the K2 or in the EC2 enclosure with the KAT100?
If you have the KPA100 mounted on the K2, remove the right side panel
and dress (fold) the ribbon cable and the speaker cable up into the area
above the Control Board. If left to its own resources, the signals on
the ribbon cable can couple into the KSB2 board.

Just completed and tested a KAT-100 in the EC2 enclosure. Like the K2 and the
KPA-100, I turned it on, and everything worked fine.
I think I may be seeing some digital noise getting into my K2 from the addition
of the outboard tuner. I saw some discussion recently about noise from the RS-
232 cable in the K2. Have others seen any problems with noise when adding the
KAT-100? If so, any tips on minimizing or eliminating it?
