Bob, I think you are right. Your tuner is defective. There are two more
owners of 1.3k-FA live next to me . None of us has no issues. Tuners
work well up to 3 :1 SWR and beyond that if you tune them manually. I
have inverted L for 80m band and with tuner I can cover from 3.5 to 3.8
even though SWR is up to 5:1 some frequencies.

I've got the 1.3K with the internal tuner and am very dissatisfied
with the capability of the tuner. If I had it to do over again, I
would would get the amp WITHOUT the internal tuner. It won't tune
certain loads (e.g my beam on the low end of 20 where the SWR is only
2.1/! and on 30 meters with my vertical (same situation), and I also
find it there are many occasions where it won't tune down to a 1:1 or
close, but stays up around 1.6 which is about the limit the amp will
tolerate. The tuner REALLY needs some work - but then maybe my tuner
is defective. BTW, my KAT 500 had no trouble matching ANY of these
conditions.

Not all of Expert 1.3 are sold with internal antenna tuner. There are
amps without it. If I were in Jerry's situation I would purchase
internal antenna tuner from Expert for the sake of integration and speed.
