Chances are that it might be copper 'tinsel' (thin flat copper strips, twisted with cotton thread) to give the cord a lot of flexibility. If it IS tinsel, any time you attempt to solder to it (as-is) you'll burn the threads first and they'll foul the copper for taking up solder. The ONLY way I've found to satisfactorily solder to tinsel is to wrap the tip of the tinsel with a VERY FIND BARE COPPER WIRE (like a single strand of stranded #24 wire... e.g a #30 or so bare copper wire). Wrap the turns around the tip of the tinsel and wrap the turns up against each other. Once wrapped, solder to the wrapped wire. This will quickly accept solder and transfer the heat to the copper in the tinsel quickly enough that it'll accept solder before the threads get to burn. Good luck, Merry Christmas, Tom Hammond N0SS ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
