The only important thing about unbalanced audio cable is that it the shield has low DC resistance. The calls for a decent copper braid shield. Mini coax like RG176 works fine. So does ordinary RG58. But remember, I said COPPER BRAID, NOT ALUMINUM FOIL! AND -- resistance isn't even that important if you follow the simple instructions on bonding all the chassis together with short pieces of copper. I use either the braid stripped from coax (equivalent to #12 - #10) or an equivalent piece of THHN (house wire). To understand all this, see the Ham Interfacing Power Point and the chapter on solving problems in the shack in my RFI Tutorial. http://audiosystemsgroup.com/publish.htm 73, Jim K9YC ______________________________________________________________ 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
