POWER OUT NOW 15 WATTS MAX, 80-20 M: On 80-20 meters, the PWR control can
now be set as high as 15 W (max is still 12 W on other bands). 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.
Odds are it's the Voltage: this is what I usually run into.
