I had been using a power pole strip to power everything. After seeing some discussion on this topic some time ago I found that in the string of 3 power pole connections in my setup at the time I was seeing around a 1 volt drop in the voltage on the K3 metering between receive and 100 watts keydown. That voltage drop was confirmed by my VOM so I wired the rig directly to the supply and the voltage drop was less than 0.25 volts. That is the way my rigs and VHF/UHF amps will be connected from now on with only a fuse inline. The low current stuff will stay on the power pole strip where they do just fine lighting up lights and stuff.
