kx3 foldback setting?

[Reginald J Mackey SR-3]

Is there a swr foldback setting in in the kx3? I can't find such. my friends kx3 keeps folding power back while swr is 1.1 or 1.2. I suspect it should not until at least 2.1. any help?

In that case, Rsther than SWR, the fold back is more likely due to low or drooping supply voltage. Could also be due to temperature, if you are running the radio hard.

Odds are it's PA temperature issue. I believe the
power will roll back when 60 deg-C is reached.

That should only happen in high duty cycle modes
(digital, FM, etc.), not in CW or SSB. If he's
getting roll back in SSB or CW there must be some
other issue.
