[Elecraft] Any way to automatically bypass K3 ATU when using KPA500?

[iain macdonnell - N6ML]

I think you're missing the point, Keith ... or maybe I am. If you tune
the KAT3 to match the amp, then it will not match the antenna when the
amp is out of line. Of course this somewhat begs the question; how is
the antenna being matched when the amp is active? Maybe it's close to
2:1, which is still acceptable, but the original poster wants to use
the KAT3 to get a better match when operating barefoot...
