Re: [AMRadio] Noise Update
A couple of years ago a friend of mine suddenly had a wide band HF noise problem. It was found that the TV cable in his neighbor's yard had a broken shield.

Re: [AMRadio] Noise Update
I had the same thing happen in my house. I sounded like a small signal gas engine running. At first I blamed it on the neighbor snow blower. I took a am portable radio and traced it down. Turned out to be a 13" portable tv. It would not come on. I unplugged it and the noise left. If you want it, it's by the road. Trash pick up is in the morning.

Re: [AMRadio] Noise Update
cMike, Sad to say but I just experienced the worst case scenario with a fire in the business below my workshop downtown here on the 21st. The previous night I had heard a nasty arcing noise while listening to 75 mtrs. It was not constant enough to locate but by its strength and type knew it was nearby. Well, I was awakened at 9:00 AM the next morning with the news that the building downtown was on fire !! It was controlled after a couple hours and the following day the Fire Inspector determined that it was caused by a shorting coffee maker cord that had showered sparks on flamable materials nearby causing the blaze. The rear of the business, my Neice's pet shop, was completely gutted and I had major smoke and water damage in my rooms directly over it. The fire had climed up thru the walls to an attic crawlspace over my area and the water used totally soaked my test gear, radio gear and everything else. I was lucky with no actual fire burn damage but the smoke and water has probably ruined all the electronics that I have including shelves of manuals and handbooks. I had just put my old VK II back on the air a couple days earlier. So check out any serious noises not just foe QRN reasons but to prevent a real fire ! Bill, KB3DKS -Original Message- From: Mike Duke, K5XU Thanks to those who offered great information about using various noise canceling systems. Today my power company was at last able to speak directly with the owner of the home where my noise is originating. The home owner and I were able to determine which breaker causes the noise to disappear. He's checking to see what is connected to that breaker, and said he would call me back "soon." While the problem isn't fixed yet, at least there is dialogue.
