That was my first thought - so I laid out a new coax to the antenna.
That said, this morning everything works just fine. I can only figure
the KAT500 heard me say that it was leaving and it decided to work. Be
interesting to see how long this holds.

It is possible that you have bad coax, a bad connection or water ingress in
your antenna system. It would be interesting to see if a manual tuner
remains stable.

I have done the reading of the printout - some really crazy SWR numbers
for the antenna that I know are not correct.
So far as RF in the shack - I might consider that - if things had not
been working correctly until abut a month ago. Nothing has changed until

Since you are running KPA500 along with the KAT500 and you stated you don't
have a balun, I assume you don't have a common mode choke either.
I suggest a trip to http://audiosystemsgroup.com/RFI-Ham.pdf as I suspect
you have RF in the shack.

After a good tune, I would use the KAT500 utility to examine and record the
selected component values.
When the failure occurs, before retuning I would look at them again and see if
they are the same.
Also after a good tune, I would run up and down the band to cycle the relays and
see if thi
Bill,
After you do the initial TUNE (training the ATU), do you switch it to
MAN? If not try that and see if it corrects your situation.
If not, then it is time to contact support.

Have you checked your KAT500 with a dummy load instead of feed line?
This would tell you either your KAT500 or feed line to antenna (and antenna) is
in trouble.

KAT500.
The antenna in question is a simple 75 meter dipole fed with coax. You
tune the antenna at 3922, 2955 and 3975 - just for example. When you
return to those frequencies, a few hours later, the tuning is all off
