Ignacy, I sent you a more detailed message direct. Have you got a VHF yagi you could more accurately pinpoint its direction? If so, does the VHF noise match the HF noise? Helps a lot if the noise goe

At what distance would one typically notice residential solar system noise on HF? I'm lucky so far, none around me. And to tell the truth I am not aware of any in the area. I'm in SW TN. My county is
