Since you're using USB, you might want to be sure you have the TX EQ

Filing, cutting or otherwise breeching the plating

With an ohmmeter, everything will look shorted in the LPF section. If

Ed,
The LED bargraph indicates approximately 1/2 watt per bar, so yes, 2
bars = 1 watt, 6 bars = 3 watts and so on.
The KXAT1 will remember the tuning for each band, so after you do an
initial TUNE to match an antenna on any one band, there is no need to do
a tune after switching bands.
Okay thanks Don.
