[Elecraft] KX3 won't go above 10W

[Fred Soop]

I have looked at the power issue (even though I'm not yet a KX3 owner) and with NiMH cells at 1.2 V, the 8 cell internal battery holder would only be 9.6 V. I'm considering an external battery pack with (2) 6 cell holders for 12 cells total. That would be 14.4 V total. A single series diode would bring that down to 13.7 V. The NiMH cells do start at 1.5 V with full charge for a short time, so some additional series diodes would be needed with a fresh charge and could be switched out as the cell voltage drops to 1.2 V. A voltmeter and rotary switch with 5 diodes would do the job.
