I'm not sure which part of what I did managed to make the machine confused enough to lose the bias setting... Had I known ahead of time that the error indicated that I would have just run that calibration .. but did whatever caused that problem step on other calibration data?

Also the KX3 has to be powered by a power supply and not the internal batteries for the TX Gain to calibrate. Glad you're making headway. I had no problems with kit number 21.
