Tommy,

That is too much voltage drop. Check all your power connections to be sure they are tight. If the power supply terminals rotate even a little bit, open the power supply and tighten the terminals securely.

Since the KX2 power control tries to maintain the set power, if the voltage drops, it has to draw more current. That means your KX2 may be exceeding the current limits due to the reduced voltage.
