First, 100% shield is meaningless. What matters is shield RESISTANCE. Second, RG58 that has copper braid shield works quite well. You buy some RG58, you buy some Switchcraft or Neutrik RCA connectors, and you solder the connectors onto the cable. Premade RCA cables have very flimsy shields (or are often not shielded at all, but rather have a single wire inside the jacket), and they are usually made of cheap metals (or thin metal coating) that causes dissimilar metal problems and/or high contact resistance when plugged into your radio. Switchcraft and Neutrik RCA connectors are widely available from real industrial electronics vendors like Allied, Newark, Digikey, etc. They aren't cheap, but they are far more robust, and their contacts are made of good metals that don't have these problems. Another point. Study my Ham RFI tutorial and the power point on Ham Interfacing, which show you how to kill hum and buzz simply by bonding all your equipment together and getting power for all of it from the same outlet. http://audiosystemsgroup.com/publish 73, Jim Brown K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
