Leigh,
The KAT3 is internal and very tightly coupled to the 10-W or 100-W
stage. While you could in theory interpose an external amplifier
between the 10-W stage and the KAT3, we haven't tried it, and it would
require special firmware support.
I really wouldn't recommend this. The KPA3 is a high-performance 160-6
m 100-W module with excellent heat sinking, monitoring circuitry, two
fans, and its own circuit breaker. This results in very smooth
high-power operation, while an ad-hoc solution external to the radio
might not.
We also don't plan to support the KAT100, for [very good] reasons I
outlined in my earlier posting on the auxBus. This will be added to the
FAQ.

I operate my K2 with an external amp but use the KAT100. Will the
K3/10 and KAT3 combination be able to work with an external amp inline
or are the connections available only internally?
I realize there may be more advantages to the integrated K3/100 than
with the K2+KPA100 but this mail thread is about sharing an amp
between the K2 and the K3, and while we now know the KPA100 can't do
this, I would like to find out if the K3/10+KAT3 can support a
two-port box in the middle.
