Yes, but one screw-up on the remote sensing system and it will take
advantage of the voltage overhead on the pass transistors and likely
wipe out every piece of equipment. I strongly do not advise it.
And you make a valid point for NOT using remote sensing.

I have thought about doing that. Just requires a 2 wire hookup with small
gauge wire. But I run all of my small items like the remoterig box, LP-pan
box, VHF/UHF rig and so forth off of the main supply and if I have a larger
than anticipated voltage drop on rig power cable the voltage on the other
tings could go fairly high. The power supply is a HB thing with at least a
50 amp capacity and plenty of voltage overhead before pass transistors.
(Used to run 2 HF rigs before downsizing.)

Why hasn't anyone used remote sensing at the radio voltage input?
As far as I know all of the Astron supplies don't have external sense
wiring. Many so called professional grade high current supplies provide
For external connection of the voltage sense back to the regulator chip.
I've toyed with this idea a bit but haven't had the time dig in to the
Astron supply I have. If this were implemented then one could maintain
13.8 volts or whatever you desired at the radio power supply inputs,
Regardless of the current draw.
