[Elecraft] K-Line: Connections?

[Jim Miller]

I'm considering adding the KPA500 and KAT500 to my K3/P3. I've got a couple
of questions.

1. How does all this communicate with each other? Will it be through the
serial connections or some AUXBUS cabling? The two pictures on the website
don't show how this is done.
2. In talking with others about how they use their amps and tuners (not
Elecraft) they tell me about all they gyrations they go through to achieve
tuning. Will the K3/KPA500/KAT500 just do the right thing when the K3 tune
button is depressed, i.e. tune at 5W as it does at present? Or will it
require manual intervention?
