Yes true. However seeing they way some hams configure their stations,
building or modifying and implementing a power supply with voltage
sensing, is of serious questionable nature. Likewise, in conditions
where power supplies are buried under the desk. One needs to see the
volt meter when

Typically, there are small resistors at the power supply between the output and
sense terminals to prevent the voltage from rising if a sense wire opens up.

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.

What, never had a carrier
I do use voltage sensing at the rear of the radio. Astron supplies can be
modified easily to do this - they already have sense wires tied to the
voltage output terminals. Basically you disconnect them there and run leads
(keep em short) to the radio. On transmit, my K3s drops less than 1/10 a
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

As far as I know all of the Astron supplies don't have external sense

The ACC cable can be connected through a simple Y cable (I think I bought
