And if it was a defective cable or wiring setup on the scope, it would be present on antenna #2 and in fact everything else I hooked up to my scope. Antenna #2 shows none of the 60-hz harmonics, for whatever reason. It also has nothing to do with the ground on my other equipment, since no other equipment is involved when the scope is put on the antenna. It's just a bunch of hash that has 60-hz harmonics and garbage overlaid on it. I received about a dozen emails from other guys who tried the same thing and observed the same sorry mess coming in on their antenna, even those with fairly rural locations. I realize that the low-frequency garbage I see on the scope isn't getting through the receiver to my headphones; my original post was mainly just to lament the sad state of the ether, filled with so much ugly junk. As a side note, however, I must say that I hear more HF noise on antenna #1 than on #2, so it's tempting to believe there's a link between all the LF noise it picks up and the HF noise. Anyway, if you are having a cheerful day and are looking for a downer, scope all your antennas and see what you find. 73, Tony KT0NY ______________________________________________________________ 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
