I will try a simple low dropout regulator for mine.

Glen,
There a number of down converters from which you could choose to run the
KX3 off of a higher supply voltage - and they are inexpensive. Below is
the ebay listing for one such device. I have this one on order to test. I
have yet to get it and can not validate it yet. Do note that the output
voltage has to be 1.5 volts below the input voltage. Most important will
be the RFI it may generate.

Hi All,
I have a KX3 and am doing some SOTA activations.
I have obtained a 4S LiPo battery which is somewhere north of 16 V with
full charge.
I would like to get a DC-DC regulator as a more elegany solution than
series diodes.
I have searched and searched but no solid outcomes.
Anyone have any input on where to find such a regulator?
Many Thanks,
Glen
