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

[Bill Johnson]

I have this setup.  It works well.  I would suggest a menu change to 5 watt
tuning with the KX3.  Do not tune everything at once.  Big error.  Do you
have a tuner in the KXPA100?  If so set on "Man" then tune the KX3 into the
KAT500.  This will stop what you are seeing.  Too many tuners going at once
will cause what you are seeing.  If that doesn't work, turn off the KX3
tuner and use only the Kat500.  Once tuned the rest should work.

73,

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
