Personally I'd try to correct the antenna issue so the tuner in the
KPA1500 performs as designed. The antenna should be able, with the
KPA1500 tuner, to cover then entire 75/80M band. Although I use the
KAT500, same equivalent circuit, I have no issue with full band coverage
on 75/80M.
As to the Palstar, I'd take Jim's advice, and find it a new home. Two
automatic tuners in line is a formula for disaster as I view it. If
you wish to use the Palstar all of the time, then set the one in the
KPA1500 to bypass all of the time.

The problem you will run into is if the antenna SWR changes above the threshold
for both the KPA1500 tuner and HF Auto bothtuners will initiate a retune and
the two will be fighting each other.
Example - ice, branches against antenna, etc.
For the bands where you need to use the HF Auto, you are better off leaving the
KPA1500 in bypass.

I think instead I'll go the route of always leaving it in line, but that
method would certainly work too! Thanks, Paul!

The HF-Auto (external automatic tuner) is bypassed everywhere except the
range of 3650 to 4000, and 7100 to 7300. I would like to automatically have
the KPA1500's tuner go into bypass at the above ranges,
One method (there are others) is to connect a dummy load to the KPA1500, and
do a TUNE for each bin in those ranges. The tuner will then learn to go into
BYPASS for those BINS.
