You might want to look at some of the DROK buck converters.? I
think they have one that will do what you want, & they are
very power efficient.

I think you'd be best served by using a regulator to turn
13.8v into 9v, rather than trying to redesign the radio to
natively run on 13.8v. I imagine a suitable circuit could be
installed in the 18650 battery case on the side of the zBitx
case, rather than putting such a heat source inside the case.

Personally, I plan to use the battery powered option, but I
do understand the desire to operate from a standardized 13.8v
power source...
