[Elecraft] K3/KPA500/KAT500 SWR problem

[Richard Solomon]

OK, so now we have heard from a few folks that have this problem.

As a soon to be purchaser of a similar set-up, I am quite concerned.
What is the solution to this problem ?

I read one post about putting the Tuner in Manual mode, but I also
read that another user has had the problem in Manual mode.

How does one fix this ?
