[Elecraft] zeroing K3 internal tuner

[zabarnick .]

Since I exclusively use balanced ladder line fed antennas, I have been
using an external Palstar balanced tuner rather than my K3 internal
KAT3 tuner. Recently, I've decided  to give the internal tuner another
try.

I find that on some bands, even though the KAT3 brings the SWR match
below 2:1, the transmitter output power is reduced from 100 watts to
the 60-70 watt range. I don't see this issue with the external tuner,
but I can almost always find a 1:1 match. Is this because my muti-band
non-resonant doublet is providing impedances that are too difficult
for the KAT3 to match? Or is something more sinister afoot?
