[Elecraft] Re: K2 + K3 SO2R?

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.

73,
