[Elecraft]K2 + K3 SO2R?

[Leigh L Klotz, Jr.]

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.
