It doesn't need much swr increase to trip, A rise to 1.7:1 will do it
despite that swr fine for use.
You did not comment on the SPE indicated swr. Can you see it rise just

open....I inserted a barrel connector and all is well....except on
stuck on 160.....tomorrow, in between other projects, I think we will
