[Elecraft] [KX3] KX3 Supply Voltage reading low

[Arlen Fletcher]

Greetings all!

My KX3 has the set of internal NiMH batteries and currently reads 9.9v while idling (I haven’t charged the batteries recently). When I power the KX3 from an external 12V SLA battery - which reads 12.2V on my Fluke DMM - the KX3 reports 10.2V while idling. I might expect the KX3 to report slightly less than 12.2V if there is a diode on the supply input (I haven’t checked the schematics), but 2V seems like a significant difference. I’d welcome any feedback from the list on this issue.

Thanks!
