Re: [Elecraft] RFI on K3s

One can convert red/black zip wire pretty easily: zip wire separates by pulling the red side away from the black so you end up with two separate wires (you can even leave the power-pole connector on one end). Then twist the two wires to obtain twisted-pair. No waste of those existing power
