[Elecraft] KX3 clock & battery. (Was KX3 clock will not, set from KX3 utility)

[Walter Underwood]

From the instructions for the KXBC3, page 2:

“Only a few microamperes of current are required to keep the clock running when the KX3 is off. This is supplied by either the external power supply or the internal batteries.”

I believe the KX3 always uses the source with the higher voltage, whether it is internal or external.
