Although the KAT500 would like 20 watts to get a good tune it should be able to tune down to 10 watts (from an email long ago from Elecraft). Maybe you can try turning the KXPA100 off and setting the KX3 to 10-15 watts (depending on the band) and then tune the KAT500.

Thank you to the three people that responded to this so far but each of you accused me of having my friend run three tuners in a row. 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. Thank you KEN.
