Nothing is changed in the shack except in using a 4:1 balun instead of a 1:1.
The timing is similar.
Tomorrow I’ll reinstall that and see if it persists.
An arc outside is a thought too. I will check my open wire feed
It sounds like you may have the KAT500 set for AUTO. Change it to MAN and it
should perform much better.
The rapid signal changes associated with SSB operation can cause issues with
the sampling of the power in the directional coupler,
causing readings that make the KAT think it needs to do a
Something arcing over on voice peaks would do what you describe. Are
there any weak insulators or spots where something might arc?

It might help if we knew more about the antenna system; what antenna,
balun, power rating of them vs. power running, RF feed back in shack,
any other info might help us point at what to look at...
I used to have some similar events, and got rid of them with a
combination of toroids and
I've been having my tuner go to high swr a random voice peak.
The utility shows the right settings after a drop out but the Amp Key Interrupt
box is checked.
And the swr showing on the LEDs is high.
Not sure what is going on.
I get it back to operating at low swr by doing a tune.
