I believe the KX3 does have a diode in the line. Bottom line, the radio doesn’t care what your Fluke says, it uses its own voltmeter and acts on it. I owned a KX3 for a while and felt a bit behind as the radio was introduced with NiMH battery technology just as LiPO battery technology was just coming into full bloom. If the voltage range were just bumped up to 16-17 Volts. A nice 4X? Pack would be great. A 3X pack is barely enough.
Think the KX2 is now a better deal. But my portable days are over. Sadly.
