Tom,
A Buddie Pole - homemade or otherwise - should tune near resonance on
the selected band with the coil taps. If it is horizontal, then make
both sides the same. Check the end of the coax that attaches to the
transceiver with your antenna analyzer - if it is far off resonance, it
may be out of range for the KX1 tuner.
The KX1 tuner is optimized to tune int the no-feeder antenna shown on
page 9 of the KXAT1 manual. The L/C ranges are limited - Inductance 0
to 4.7 uH in 7 steps and capacitance 0 to 470 in 7 steps. If an L
network with series L and shunt C within those ranges cannot form a
match then the load is outside the range of the tuner.
I suspect your homemade buddy pole is out of range and a balun will not
change that. Tune it up with an antenna analyzer and try again.
