Reggie - That is really dependent on two things: the power supply design and the current you are drawing. Are you using the same power supply for both the ts570 measurement and the k2 measurement? (Also if you have a light gauge wire between the power supply and the k2 and are using the K2

That is very odd indeed. You should measure at the other end of the wires, to see what the radio is seeing, but I'm afraid that would make it even worse. Can you measure the current being drawn? That would be an interesting figure. Are you certain RF isn't getting into the PS or the meter?

I would suggest that the problem is inside the power supply - perhaps something as simple as a poor connection on the inside of the output terminals. Even the drop you are seeing with the TS-570 seems excessive to me. We don't know the actual current being drawn, but it may be quite
