The only thing that has a flat 1:1 SWR from 80m to 6m is a good quality
dummy load.

Greetings,
I joined this list today, after sending a message to Elecraft support,
describing a similar problem. I have an Icom IC-7610, with the KPA500
and KAT500, and my SWR spontaneously climbs into the red sometimes
during transmissions. It takes some effort to correct it, and I
typically lose a QSO in the process. The relays go nuts trying to
re-tune, and sometimes produces a fault condition. Usually, I can
correct it by restarting both the amplifier and tuner. I have a Comet
CHA-250HD, which has a almost a flat 1.1 SWR from 80m to 6m. I don't
need a tuner while barefoot. However, when I first hooked up the
KPA500, the SWR was not flat, and added the KAT500 this week, which
led to my SWR issue.
I hope the cause and resolution can be determined.
