Craig, When I was in the Army in the late 50s, We used WD1TTwhich sounds likeĀ WD1. I see that someone has it on eBay.
73..Price W0RI These are two different kinds of wire. WD1 is designed for the old tip and ring phone systems of the 40's-60's and consists of two twisted seven conductor wires, three galvanized steel and four tinned copper conductors. WD1A came out in the 70's and is smaller and joined together like zip cord. It has the same conductor combination as WD1. They also have different impedances so their feedline matching is different.
