Thanks — now to see if I have that upgrade.  Or, I will just take the time to upgrade everything.

Supply voltage must be over 12.8 V on key-down as indicated by the KX3’s voltage display (tap DISP, rotate VFO B). Note: The KX3 will automatically reduce power as required if current, SWR, or temperature is excessive, or if supply voltage is too low. If a band other than 80-20 m is selected, power output will be cut back to 12 W max. It must then be manually set above 12 W after switching to 80-20 m.
