I was on 80 meters and saw a HI SWR warning come on the KPA500 software, but not on the KAT500 software.  I clicked the "Clear Error" area and then received a Comm ERR.

I re-started the software and it gave me an error message saying it could not make contact with the KPA500.  I closed all the running programs on the remote PC, and then did a re-boot.  All is working well except for the KPA500 software.  I keep getting an error message telling me the KPA500 remote is not running and it can't find the amp.

Unless you have a way to remotely cycle the AC supply to the KPA500,
you're "SOL". I have a relay on the 220VAC supply going to mine, which
runs off the K3's ACC 12V output, so if I power-cycle the K3, the
KPA500 follows. It is necessary once in a while, when the firmware
hangs.
