A scary FCC letter is all you'll get out of the FCC today. There's no teeth in Part 15 enforcement when it comes to anything but power line noise, and BPL proved that not solid either. I have not hea
Manassas had an early BPL system that caused HF interference. But this more like a area full of wireless mesh routers. It is not BPL. But the switching power supplies could cause interference just li
Tom, If you have a UPS or two or more, shutting down the house power does not stop a RF noisy UPS. You must remove the batteries from the UPS units. I have one UPS in the ham shack and my telephone c
True if it's 40 over S-9 on 6 meters & up. False it's 40 over S9 only on 160 meters and zero s-units on 10, 15 &/or 20 meters. It is frequency dependent if power line noise. Conduction can bring RFI

I agree Mike. The toilet water flush reference is way off topic. The solar-nuclear reference (also off topic from LED bulbs) is a bit closer to root cause of the problem needing to replace shrinking
Four 8ft ground rods spaced further apart would be better. Up to 16ft apart max. Bonded together underground as well. Add a few more rods, and you could reach the AC panel's ground to bond it all tog
If it's not local to your location and many are hearing it, once it's been reported to the FCC it won't be on long enough to stay in any database. If it's only local to your location, then it won't b
I searched the RFI reflector about LG brand inverter compressor refrigerator's RFI issues, but haven't found any comments on Linear Inverter or Smart Inverter refrigerators in the RFI archives nor ma
We have CenturyLink with FTTH (Fiber To The Home). The market this with wireless cable inside the home using wireless TV boxes that radiate RFI noise from AM band on up to 400Mhz. Tried ferrites on a
This is supposed to be an RFI reflector, not a politics reflector. Right? The reality is, we suddenly have FCC action possibly for the first time on this issue. That doesn't really fit your narrative
Mark, I recommend you ask for their department or group responsible for their FCC licensed 2-way radio and microwave radio systems. Ask if they have a telecommunications group maybe within their Info

John, Seems we can always get more turns around a toroid ferrite (several) than you can on a snap on ferrite (maybe one). This would make snap-ons less effective than a toroid core based on number of
