David,
Be careful about checking for 13.8 under load because you don't yet know
how much voltage drop you have in the power cable.
Check the difference between load and idle at whatever voltage you have
right now.
You MUST keep the maximum supply voltage to less than 15 volts.
What I am saying is that if you have significant voltage drop in the
power cable, then setting the voltage under load to 13.8 *may* result in
greater than 15 volts no load.
If you have significant voltage drop in the power supply to KXPA100
power routing, fix that first.

Hi Don,
Thank you for the reply. Is there an ideal voltage under TX/ load?
13.8V under load is easy, so is 14.5+. If there's advantage to running
higher voltages, I can, but if there is no advantage I'll just target
13.8 under load and call it a day and not worry about dropping voltage
for other components.
