It does not have that red dye in direct contact with the conductor. Those that I have done the autopsies on, did. There are not today, any surviving 1970's era microphone cables on cb radios of the era as the red wire in them, normally carrying the push to talk signal, will be found to have only a rust colored powder where the copper of the wire was. At Norfolk 2-way Radio, where I spent several years on the service bench, I probably replaced entirely, 3 hundred of those cables with the bright, almost magenta dye in the "red" wires insulation. Some of them more than once for this problem because we had a heck of a time trying to source cables with the older, darker red dye like Belden originally used. That darker red dye didn't have the chemical time bomb effect. By 1977 even Belden was shipping the Japanese cable.
That (Oct 1977) was about the time I moved $DAYJOB to New Mexico as the Chief Engineer at KIVA-TV in Farmington & I hardly had time to keep my own CB gear running. > sam > > On 10/8/2017 12:34 AM, Erik Christiansen wrote: > > On 03.01.12 23:32, gene heskett wrote: > >> But I have to get rid of the rest of those red sata cables.
