A final update on this, as the problem is solved.
Jack looked at the logs and had a number of things to comment on, all very
helpful. I knew this was not going to be solved without a trip to the
remote base. It was not a simple software problem.
I am a big fan of looking at the facts (not
I wanted to say thanks to Jack for spending time after hours analyzing my
KPA500 log and providing some detailed analysis.
While I haven't solved the problem yet, I have enough clues that possibly
support my theory of a bad AC supply line.
I will likely get to my remote base over the weekend, so

It could also be tiny livestock nibbling at the wiring, making nests etc. (or

Perhaps outdoors you have had a ground go bad, or a connector go bad, to
all of a sudden have RF in the shack. Connection work loose, that kind of
thing. These could happen without your seeing SWR on the line you are
transmitting on.

Thanks Jack for taking the time to reply.
No faults are shown on the GUI. There is no connection to Pin 8 of the Aux
connector either.
I will try to pull a dump tonight when I get home. I will also do a trap
on the serial line to see if I can capture any data during a failure. That

Mike;
There is no event in the firmware that should cause power down other that
activating the power on/off signal, either through the front panel button or
the AUX/IO signal. Having said this, obviously something is going on.
You don’t report any faults being shown, but that doesn’t mean there
Not an SWR issue. I can see the SWR on the KPA500 and on the external W2.
Both would alarm if the SWR got above got above 3:1.
At least, for the moment, I have eliminated that.
It could be breakdown in an antenna switch, but that would again show up as
something other than the until powering
First thing that comes to mind - high SWR.

I run a remote base with a KPA500. The Amp is a 3 hour drive away.
I can control just about everything remotely without effort. The
installation has been rock solid for years (Flex 6300 / KPA500) and lots
of chokes everwhere.
Last week the unit worked fine. Today the KPA500 appears to shut
