What is the voltage off-load when it is set like that?

But the K3 power switch is a "soft" switch isn't it, so some electronics are
still connected to the supply even when the switch is off?

Mine consumes 30VA even when no load is present, so for the sake of the
environment everything here now gets switched off at the mains when not in
use.

The supply cable for the K3 certainly uses less copper than the ones
supplied with JA radios. The PowerPole connectors seem a bit wimpy to me as
well.
