The list has sustained a fairly long thread regarding grounding, lightning, NEC, and a myriad of related and semi-related subjects. For those with interest as this thread goes off-list:
Jim, K9YC, references Henry Ott in a couple of his web articles on grounding. Ott coined the phrase, "The hidden schematic behind the ground symbol." It turns out that the ground symbol [and ground in the real circuit/system] is a lot like infinity. We can't help but think of it as a defined place -- unfortunately, it isn't, and lots can happen on the way down that yellow brick road. So it is with grounding and radio. I highly recommend Jim's articles to anyone about to build Elecraft gear [or any other as well], or who is concerned about his/her station safety. They apply to any situation where a static charge could destroy or damage something [or kill you], from shuffling your feet on the carpet on a dry day to multi-gigavolt electrical displays in the sky, to how hum and noise find themselves into your transceiver, all because of that schematic behind the ground symbol. www.audiosystemsgroup.com scroll to the bottom and click on the Publications link. Usual Disclaimer: Jim's a friend, I know he is *very good* at this stuff, he offers it free, and I have no financial interest in his group. I just really don't want to hear about an electrocuted ham radio operator. 73, Fred K6DGW Auburn CA ______________________________________________________________ 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
