The PO for xverter bands can be on a per band basis. It is all in the config menus.

XVn PWR:
Sets upper limit on power level for XVTR band n. (Tap 1 – 9 to select band.)
H x.x (High power level) specifies a value in watts, and use of the main antenna
jack(s). This should be used with caution, as you could damage a transverter left
connected to these antenna jacks accidentally. L x.xx (Low power level)
specifies a value in milliwatts, which requires the KXV3 option. L 1.00 is
recommended for the K144XV internal 2-m module. (If CONFIG:PWR SET is
set to PER-BAND, the K3 will save the last-used power setting on each band.
This is especially useful for transverter bands.)

HOWEVER, it appears that 1mw is required for the K144XV.  I believe that is so the PO of K144 can be calculated by the K3 FW, as there is no direct measurement of the 144 PO.  Once the gain of the K144XV, I believe the calculation will be incorrect for display.
