Out west we have the Pacific Dc Intertie, a 500KV system bringing power to So Cal from Oregon. Is anyone aware of any noise issues with that? Jeff W6JK Hi All Through the center part of Illinois they

I don't think you would have noise from the line except if there is a fault that is causing arcing at an insulator. I'd hate to live near the end points where the AC to D and Dc to Ac conversions are

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 t

Skip, I went on a road trip to Northern VE2 some years ago. There was an enormous transmissionline near the road we were on. I tuned in 1710 khz on the truck radio and there was dead silence...NO RFI

Not if you understand the physics and the details of how the lines are built and maintained. ARRL publishes Marv Loftness's book on AC power noise issues, which I added to my library a decade or so a

American Transmission Company built and activated a 345KW line right thru Madison, WI two years ago. Huge towers, huge green glass insulators. The line runs right past my XYL's office window, about 1

Many electric company employees' are from families that have worked in the industry for several generations. If they worked in the plants they would be near hundred+ megawatt generators for decades.

You don't step off a combine when harvesting under HVAC lines. You learn to jump off real quick. I think it is capacitive coupling. The larger combines pack a real wallop when under HVAC lines. I liv

Gents: The shock one would get under such circumstances was one of the reasons that early studies into the effects of HV AC lines were flawed. I believe even Brodeur's work cited this erroneous work.
