Thanks to everyone for the quick responses and product suggestions. When bought a MicroHAM Micro2R years ago to replace a Top Ten DXDoubler I used the old Top Ten cables. For years I had rotator controller noised getting into my headphones and I recently noticed that the headphone cables were not shielded. I stared over making new cables using better headphone wires and the rotator ramp noise is now completely gone. My next step is to add mic cables to this device and I wanted to do it properly. K9YC's detailed explanation was exactly what I was looking for. I was not sure use if I should I should buy one or two conductors and if two what to do with the shield. This morning I purchased a 2 wire Belden mic cable and I will probably buy the Foster connector that W3FPR listed. Also thanks to K4TAX and KY5G for their excellent suggestions.
