What Can I Do About My Strong RF Noise?

You killed the main AC circuit breaker to your house, but still detect RF noise centered at your house? Battery operated devices (laptop?, electric car?), systems with battery backup, and batteries with DC-DC converters can still produce, perhaps radiate, RF noise. The solar panels might have DC-DC converters that can't be switched off. Try throwing a pool cover over them

I have a problem with strong and constant received noise, from S7 to S920.

I've shut off the power, both in my house and two neighbors' houses.

I took my portable rig with a Hustler antenna and searched the neighborhood. The noise seems to be at my house.

I've turned off the solar and main power day and night. It never changes strength, rain or shine, night or day. Not a street light either.

I'm using an MFJ 1798 vertical. I've had it for several years now. When I first installed it, the SWR was low. Now, something has changed. Now it's out of tune slightly, and I hear steady hash-like QRN. I called MFJ about the changing of the tuning, and they said the balun came partially unwound. It has not. Could my antenna system be the problem?

I have exhausted all of my ideas to solve this problem. Has anyone else come across a similar problem that you were able to solve from which you could share some insight? Can you recommend anything else that I should test or try in order to reduce or eliminate the QRN?
