ANY ham rig needs that. :)  At 100W, the K3 draws about 20A keydown. Do 
Ohm's Law on the wiring between the power supply and the K3. The simple 
answer is short, fat copper, straight from the supply to the radio. AND 
good quality connectors. Those power distribution strips can easily drop 
a volt or so. I run #10-2 to my radios.
