I promise you, you DO NOT want the FCC asking you to cease and desist with RFI. It is the end consumer who is ultimately responsible for making sure what they own and operate does not interfere with another single device or consumer.
The FCC will kick in your door and take every computer, TV, toaster, blender, microwave, calculator, wristwatch, tablet, and EVERYFUCKINGTHING you own that is electronic or electric except major appliances and may take your smart fridge if they like it.
They will take every grow light you have and any pumps or fans or any other electric or electronic device you have for grow control like co2 monitor and relay, timers, EVERYFUCKINGTHING, and leave your tomatoes and marijuana plants and take you to jail and THEN alert the police to your other activities.
They have an inferiority complex because they have just as much authority as the FBI, NSA, and any other alphabet soup agency but are overshadowed because those police agencies are cool and garner respect and make huge busts and get national attention all the time. So they make EVERYONE an example. A nuclear example.
I'd rather not argue and spend 20 bucks and keep idiots off my property the easy way. AND keep the FCC the fuck away from me. I have more money in radio equipment than I do grow lights. I want to keep it all.
