or put an antenna up at a remote site and work your righ remotely from the Internet with software, lease some space from a farmer outside of town for an antenna.

MFJ1026 noise canceller. What this does is receive the interference and feed it back in out of phase which cancels it out. This isn't some witchcraft but basic AC theory and RF is AC. They truly work.

Here's a guy with S9 of powerline noise on 14MHz using a MFJ 1026 which takes it down to nothing.

looks like you ain't getting much help,....... .

finding the source can be a learning experience.

the next thing you should do is to power your radio from a 12 v battery and open the main breaker on your electrical panel.

you really don't KNOW yet that it is from the power lines, it could be something else,.. neon signs, ,. a neighbor growing pot,.. something in your house, ect.

also,....does the noise change when it rains?

Yes there is somthing that can be done,

First you have to eliminate potential sources in your own home. That entails powering off the mains to your home and running the radio and current antenna from a battery. If you eliminate it then you can turn the power back on and figure out what device in your house is the culprit. If you still get the noise then the source is external of your home. Then it gets fun.

It could be coming from a neighbors house, a bad power line transformer or fuse or just the high voltage lines themselves if that's what you have running by your house. If your a licensed ham and believe the noise is coming from the power lines you can get the power company to send out their noise guy, like I did when I lived in Indiana, and have them locate the source. They replaced the transformer on the pole behind my home and the problem was solved.

If they won't come out for your issue and you can't locate the source, you could try a outboard DSP noise reduction unit. Failing all that you can learn to live with it or move.

This post is the steps you should take to find the problem.

It may very well be in your home.
I have had a simple CFL bulb cause a S7 signal in my HF radio before.....just one bulb, the other two in the same fixture did not make a sound.

This is also a way to go, yes they do work, Mole did a review on one of them here on the forum.
