AM Car Radio Reception Problem
I posted regarding this a few months ago and since then have found the root
cause of the reception. The symptoms are an overpowering hum at the low end of the am band. It is being caused by 3-phase power lines. I can follow the line for several miles in any direction with any of my vehicles and get the interference. I contacted the power company and they are supposedly looking for the cause. Has anybody had success getting this type of problem resolved? Do I have recourse if the power company doesn't fix the problem? |

Tell them where their signal is being interfered with, what it sounds like, that it seems to be following power lines (if it does), etc. If it is BPL having broadcasters not so happy about it could be a very good thing. If it's not BPL it should be fixed anyway and broadcasters have a little more pull with utility companies than individuals. Lawyers on retainer, ya know. |

Keep in mind, also that the high tension lines are NOT necessarily owned (or even controlled by utilities! Further, some of these are feeders for the interstate power grids, in the U.S./Canada. For example, B.P.A. , or Bonneville Power Administration, is a Federal agency, generateing , and selling their power to various utilities. One, that I have had experience with is the 500KV line they ran to Malin, Oregon, from the Columbia River dams! A telephone line paralleling it for about 4 miles, could measure 400 Volts of Escape (induction) at a office 25 miles away! Also, many of these are D.C. (not A.C), to avoid the situation just described (power loss via radiation/induction)- these can run hundreds of miles! There can be other things also, can cause problems with open wire circuits paralleling broadcast stations (yeh, I Know, it ain't supposed to happen, especially in transposed circuits)! In sum total, you may have to investigate just WHO owns this line, and contact THEM- Your local utility may have little to do with them- except use the energy they supply! Jim NN7K |
