Gene,
Look at the top of the K2 - does it have a black finned heatsink? If
so, that is the KPA100.
If you have 2 BNC connectors at the ANT1 and ANT2 positions on the upper
rear panel of the K2, then the KAT2 is installed. BUT the KPA100 and
the KAT2 cannot co-exist since they occupy the same physical space.
Is there something you are not telling us - like is the KPA100 mounted
in an external enclosure?
In any case, even if you do have the KAT2, it will be automatically
bypassed and set to ANT1 if the KPA100 is detected.
The ATU must be located between the PA and the antenna - so you need the
KAT100 if you are using the KPA100. Having an ATU at the input of the
amplifier does no good because the amplifier input should present a 50
ohm load to the exciter.
