David,
There is no specific voltage, except that "higher is better".
A fused distribution block will add 6 connector junctions and you can
expect .001 ohms from each one.
At 15 amps draw, that alone contributes about 0.1 volt drop.

Hi Don,
I'm making sure not to exceed idle voltages like this. If I set the
power supply to 14.2V no load, it's 13.8V under load (100W out tune on
80M). I use 10 gauge cable, so I have relatively small voltage drop
even with the distribution block and fuses involved. I'm just trying
to find out what the optimal voltage under load is for TX cleanliness.
Is that 13.8V? Is higher voltage than this better? I appreciate the
input; I'm truly just trying to find out what 'ideal' looks like under
load.
