Unless you have an 'RF in the shack' condition that creates mic
feedback, I can't think of anything that would be caused by the addition
of the KAT100 - except for the additional data traffic on the ribbon
cable to the KPA100 needed to talk with the KAT100, and dressing that
cable will help if that is the cause.
There have been problems with KPA100 oscillation that was triggered by
particular reactance/resistance combinations seen by the amplifier; and
this may be created by adding a KAT100 (or using a particular feedline
length). I experienced this myself.
The latest KPA100 mods are supposed to have addressed this problem, so
it is worth verifying that you have them installed.
