KX3 calibration questions - after EEINIT

[Andrew Moore-3]

After performing an EE INIT on the KX3 #797, per page 43 of the manual, I
understand you can avoid recalibration by restoring a saved config file via
the KX3 Utility.

However, my KX3 is showing some odd behavior with the power level setting
(resets to 0.0 W upon changing ATU MD between auto/bypass) that appears to
be solved after an EE INIT, but comes back after reloading my saved config
file, so I'd like to simply do an EE INIT followed by a manual restore my
Menu settings to my liking (CW mode B, etc...)

The manual states that if I don't restore from a saved config file, I need
to perform calibration.

However, it appears that most calibration values have been preserved: REF
CAL, gain/phase for KXFL3, TXCRNUL, TXSBNUL, etc.

I do notice that TX GAIN and TX BIAS have changed and that I'm not allowed
to enter those manually, but I can run the automated calibration.

So am I correct in thinking that all I need to do after EE INIT is run the
TX GAIN and TX BIAS automated calibrations?  Or are there dependencies I'm
not aware of that will invalidate other settings after doing gain/bias?

Thanks,
--Andrew, NV1B

Andrew,

Apparently your saved configuration contained the error too.
You mention TX Gain and TX Bias in that order, I suggest that the TX
Bias be done first because the bias will change the gain.

In fact, I would do all the calibrations in the order shown in the manual.
