[Elecraft] K3 - Power cable voltage drop

[Karin Johnson]

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.
