Hi According to the instructions for the KX-1 Power Output Mod, bundled with the KXB3080 Module, the power mod is only to be used if the output of the KX-1 is low. They are talking about 3W or less with a 14 volt supply. My output with 12.6 volts is 4W, so I did not do the mod. I suppose if you did the mod with a normally functioning amplifier chain you might run the risk of overheating the PA.
