The suggestions to try a dummy load first are right on. Do you have the
built in ATU, or just the KXPA 100? If you have the ATU I would try both
antenna outputs.
If I had to guess what the problem is I would guess that you didn't seat
the antenna connector from the back panel correctly to the atu board (or
main board if you don't have the ATU) when you were assembling the amp.
This is most likely to be the cause if you still get high SWR faults
when attempting to transmit into a dummy load.

The high SWR happens even when the AL80b or Palstar tuner is not
connected. In other words when coax from the kpxa100 goes direct to
the K4KIO Hexx beam with nothing in between to confuse the amp except
a barrel connector.
Yes you can drive a larger amp with the kx3 and KXPA100. It is covered
on page 19 of the manual in paragraph titled Keying an External
Amplifier.

Am I reading this correctly? You are driving an AL80B with the KXPA100
being driven by the KX3? That's quite imaginative if that's correct. The
SWR fault is coming from the AL80B input circuit not your antenna (the KXPA
can't see the SWR on the other side of the AL80B). probably something bad
in the input circuit of the AL80B causing the high SWR...
