XM2 300HP Cable UPS commonly used by Comcrap Xfinity here has a well documented filtering issue. Getting Comcrap to admit to it was impossible. So I asked the local power company to come out and verify that it was the source of tremendous noise. I already knew what the problem was and had been in touch with Alpha. Our power company ever so politely told Comcrap to fix it or they would cut power to the unit.
So it's not unheard of for a power company to disconnect due to RFI.

Again, interfere with big telco or licensed providers and there will be repercussions. Although this was concerning cellular telephone bands (read here "big $$") it has an interesting parallel with regular non-grow fluorescent ballasts. I've also found several external power supplies for small televisions, larger plasma televisions (these are well known and horrible) electronic washing machines and even plug into the wall USB chargers. I kept finding a cell phone charger that I had tossed several times, plugged in yet again. I killed it with a 20lb sledge.
I am very fortunate that I have great neighbors. I was able to replace switching supply wall warts with real iron and be done with it . It took a while but it was worth it .
I started out with a constant S9 noise floor, it's now less than S3 at night and none of it local.
Last but not least was the grow-op down the street. We're legal here within limits so that wasn't the hook I used. He seemed like a decent neighbor otherwise so I confronted him with...
"... I'm in no way opposed to what you're doing in your own house other than the noise it puts in my radio. However if I can recognize and find the source of the noise with nothing more than a transistor AM radio, how long is it before the neighborhood tweakers, thieves, and zombies figure it out ?
How about I help eliminate the noise and you get to keep your family, house and investment safe? "
We found an economical and easy way to fix the problem in short order. He's still a great neighbor .
No I don't smoke the stuff . Draw your own conclusions about how I feel about marijuana use. You'd be wrong .
The European Union (EU) has a great way of dealing with imported noise generating crap. They prosecute the importers,the wholesalers, the retailers, the end user, the carrier the brings to their boarder and the manufacturer . It didn't stop the production of this RFI producing crap one bit. It just gets shipped to the US where the toothless and clueless Federal Clown Commission is powerless to do anything about it even if they understood the problem. When congress and the department of Justis (Just Us) stripped the FCC of it's enforcement powers it wasn't because of their well documented incompetence it was they stood in the way of dollars, big dollars.
I just find it curious that all this began to happen hand in hand with international trade agreements that were put in place to strengthen the dollar against foreign currency.
I'm unsure whether to quote Paul Harvey or Kurt Vonnegut in closing . Either or both seem appropriate.
...and now you know the rest of the story.
...and so it goes.
