with that sort of power level, you are looking at several devices failing, and
making the system deaf as a post.
KK4QDZ - Now with Extra Class Priv's, and a tiny KX3 to enjoy them!

"Maybe it was something with the setup."
That's an understatement.
Running kilowatt-level power on the same band to two antennas only 20
feet apart is simply crazy. I don't know what input protection the
KX3's have, but they almost certainly kicked in and being inherently
non-linear they would have generated all sorts of high level trash on
the front end. It would be interesting to see the math, but I think
you're lucky you didn't blow the heck out of both front ends in spite of
the protection.
