The reliable place to measure the voltage at the K3x is using the supply
voltage display meter in the radio. I was surprised to find mine was
significantly low. I thought it was voltage drop but changing the
supply cable didn't make much difference.
Turns out the Astron power supply was more than a volt low and the meter
on the supply had been cranked up to make it appear to be correct. I
used two separate VOMs to set the power supply and then adjusted the
meter to make it agree.
Moral of the story: don't rely on the meter on the power supply and
assume a low reading at the radio is due solely to voltage drop.

the radio to the ground screw on the power supply.
That's for "bonding". Where do you pick up "ground" - at the radio, at
the PS, or at some other point?
