I know this is about a long DC line, but I thought I would add something: All the experiences I have ever read by hams living near HV AC transmission lines carrying (for example) 69 kV or more seem to indicate that RFI seldom is radiated from them.
Instead, it's the local lines on wood poles --built and maintained by your local power company, that carry 6 to 8 kV-- that cause the vast majority of RFI problems. That sounds almost too good to be true, doesn't it? Somewhere, I'm sure that at least SOME unfortunate hams are having a miserable time living near those high lines. I wouldn't want to live near one! 73, Mike www.w0btu.com On Tue, Feb 10, 2015 at 11:52 AM, Ws9v <w...@royell.net> wrote: > > Through the center part of Illinois they have begun work at the government > level to install a 690,000 VDC power line ...
