Re: Electric Corridors and Health My only concern living close to high power lines would be the potential for radio interference when receiving weaker signals.
However if you're not into radio type stuff then I guess that doesn't really matter. |

Cordova, TN | It's been a while, but what I remember is that it might completely wipe-out AM stuff, but FM stuff was mostly unaffected. |

Yes, FM is mostly unaffected as it is naturally very noise-immune.
However it can wreak havoc on AM transmissions at virtually any frequency. I've run into that a number of times with my job and have had to pinpoint the powerline hardware that was the source of the noise so that the utility could come and repair them.
A damaged/dirty insulator, loose hardware, or an arrestor that is breaking down can render any AM receiver in its proximity virtually unusable pretty much all the way up to microwave frequencies. Even minor arcing produces impulse noise across pretty much the whole spectrum, getting weaker as you go up in frequency. |

I've run into that a number of times with my job and have had to pinpoint the powerline hardware that was the source of the noise so that the utility could come and repair them. When I lived in Plantation my home was about 400 feet east of 2 135Kv transmission lines and they rendered receiving anything west of me on HF impossible and to the east was sketchy as well and that was with a 11 element log periodic with about a 20 dB front to back ratio.
Tried using a long wire antenna for north and south orientation, pffft no way Jose...

| Back in the mid-60s, I was an enthusiastic ham (K5JKX) and lived only a couple of miles from the local TV antenna farm, where both channels 4 and 9 had powerful transmitters. The difference between their carrier frequencies was exactly 144 MHz -- and because of dirty power-line insulators, they mixed to form a jamming signal that totally blocked the lower end of the 2-meter band!
