Re: [IRCA] Cable connectors

[Russ Edmunds <wb2bjh@xxxxxxxxx>]

In this case you used two feedlines, one for each side of the balanced output. Each consisted of the auto cable, center conductor pulled and the insulated wire pulled through. The center tap of the inductive link coil on the loop went to the braid, and the braids of the two pieces were soldered together every foot, then that went to ground on the FET amp.
