Jack, I had a similar thing happen and it turned out to be a tree branch had
grown into the antenna path and when on high power the antenna was arcing to
the tree branch.  Might not be a tree branch but look for any signs of
possible arching in the antenna, feed line or connectors.

After 5 years of perfect operation, now a very strange issue

Bypass SWR 3 or 4:1

KAT500 tunes to 1.3:1

Switch amp to operate, operating SBB on first voice KAT500 goes full scale
swr and amp faults on high swr

Never had a issue before, antenna is g5rv

Any ideas appreciated.
