HF/VHF Noise can be managed and eliminated/reduced if you take the time to locate it. I have had several cases of power line noise. All of them have been resolved by working with the utility (using their report process) and following up with the Tech. I have had a problem with one solar system (the DIY Type), and the noise has been eliminated. There are multiple professionally installed solar systems in my area, and I have had ZERO RF problems with them. Operators of Grow Lights can be a pain in the butt, and usually they get a letter explaining their problems are just beginning if they don't install some filtering or replace the non-compliant ballast(s). You located the noise but you can't get someone to answer the door??? The County tax assessor will provide the property owner's name, and the Internet will provide his/her mailing address (for a Fee). The ARRL can help guide you when it comes to written communication with a property owner. Most consumer products that will impact your station receiver are in YOUR house. Ferrite Beads/Toroids are your friends If you operate HF, you will need a mobile/portable receiver and a Loop Antenna to locate noise sources. Sharpen your FOX Hunting skills!!! If you have a Noise problem, lift your butt out of your chair and DO SOMETHING ABOUT IT!!!!
