Aaron,
The most common reason for a failure in the KX3 TX Gain Calibration is a
dummy load that does not present a good 50 ohm non-reactive load.
You can check your dummy load at 28 or 50 MHz with an antenna analyzer.
You apparently did not disconnect the KXPA100 when running the KX3 TX
Gain Cal procedure. Remove the KXPA100 and run with the KX3 and the
dummy load only.
If you do the manual procedure in the KX3 manual, it should be good for
all bands where it passed. If you used KX3 Utility, it quits on the
first band that produces an error.
After you get a successful TX Gain Calibration with the KX3 only, then
do the TX Gain Cal for the KXPA100 as indicated in Appendix B of the
KXPA100 manual. Your dummy load must be rated for 75 watts or greater.
73,
Don W3FPR

I have a KX3 and a KXPA100 and with the recent thread about running a
calibration I figured I needed to do likewise. The amp is a new addition to
my setup so I am still learning the details. Anyway, while running the KX3
Utility I get a failure during the calibration process (the output is
below). The amp is in bypass mode and I am using an MFJ-260C for the dummy
load attached to ANT1.
