[Elecraft] Tuning procedure for KX3, KXPA100 and KAT500?

[Nr4c]

Sorry. But my solution to this problem was to use my K3S to teach my KAT500 all about my antenna first.  Now when I hook up the KX3 I don't have to tune the KAT500. It already knows the antenna. 


What do you see with a dummy load on KXAT100 with both ATUs By-Passed?  If not near 1:1, then start here and find out why. Once this checks, move dummy load to KAT500 output. Should also be 1:1 or nearly so.

The KX3 turns it's tuner off when it senses the KXPA100 is connected and turned on. There is a setting in the MENU to turn off the tuner in the KXPA100 which we did and have to keep watching as the equipment keeps wanting to turn it back on. The problem we are having is tuning the KAT500. Hi SWRs are sent back to the KXPA100 and it trips out. I was hoping there is someone out there that is making this work. I have a K3S myself and a KAT500 and they work perfectly together at 25 watts for tuning than the full 500 watts after it is tuned. My friend does not have a K3S so we need to make the KX3 and KXPA100 work.
