[Elecraft] Sudden jump in SWR when power above 80 watts

No. When I moved the balun inside, it went from a 30' length of coax to a 4' length. No change in the SWR jump.
Likewise no difference in the jump when changing from a 4:1 to a 1:1 balun.
It's difficult to change the open wire feedline length: If I shorten it, it won't reach the antenna, if I lengthen it, it performs poorly laying on the ground ;-)
I doubt that the 3' length of coax from the K3 to the Palstar makes a 2:1 SWR difference between the two tuners on 80m.
