Yeah, although we do get the FCC to do some enforcement anyway. What is needed is a campaign to identify aggregious devices and report them to the FCC. ARRL has filed a few complaints about illegal d
Yes, and in response to a related question about how to approach a neighbor, this can be the real stumbling block. First, that neighbor does not have our understanding of the RFI issues. To our neigh
We did have a good case against Home Depot, although for a number of reasons, this didn't get followed up. We also had a problem with a Walmart device, but they stopped selling it after stockout, as
Part of the problem is that "enforcement" of harmful interference is handled by the Enforcement Bureau, which we have working somewhat well. The emissions and marketing violations are enforced by the
That is great data, Mike, thanks. In this case, it doesnt even look like a ham located nearby would have harmful interference, although there may be some noise. This actually matches my own experienc
It really is not that simple. I own "old construction" and my house is in pretty constant need of maintenance. Some people want a new home and in some areas, all of those come with CC&Rs. In some are
We have come a long way, but still have a ways to go. Fortunately, we are dealing with a company that is holding space for all of this and willing to work towards better and better solutions. The ini
I don't know why the FCC didn't follow up, but the lack of follow-up was on our end. A lot was going on at the time. Now that we can test again, I want to pick up on this, so poor W1VLF is going to h
As I said in another email, a chess game is not usually won in a single grand move. It is a gradual accumulation of advantage. I make those moves within the realm of the achievable and that sets the
W1VLF is in a relatively quiet neighborhood. He, too, had loud spikes every 200 kHz, which did go away when they replaced the optimizers. The inverter at his QTH is still noisy, so he is working with
It is far from that simple, Cortland. "Enforcement" is a very broad term that can range from the advisory letters routinely mailed by the FCC in response to complaints about harmful interference to t
Its a little more complicated than that, Dave. ARRL is funded to do this sort of thing and members expect that for their membership dues, ARRL will do what it takes to help ensure as much of a noise-
And even what is not connected to the system, but nearby. Any radiation from the system can be capacitively coupled or induced in nearby wiring and re-radiated. Grounds can be resonant or not resonan
<We were able to isolate the noise from the solar panels and associated electronics by covering the panels and seeing it disappear.> This is no different from the noise change that occurs when the su
I agree, but I like magic, so that's my story. Yes, one can actually do real science and come up with answers, but that often involved multiple interrelated phenomena that are best sorted out with ex
< That has yet to be determined Ed. Tom Simpson (SE engineer) believes the RFI could be caused by the solar panels themselves which he said has happened in the past.> If that were the case, and I and
Part 18 is primarily for intentional emitters that do not carry information. There are a number of ISM frequency bands allocated for ISM. Within those bands, no licensed user is offered any protectio
When it comes to appliances, there may be nothing to enforce. Appliances are categorically exempt from any specific emissions limits under Part 15. A refrigerator with removed filtering components ma
What may help this in the relatively short run is that the IEEE EMC Society is developing an IEEE Recommended Practice that describes the steps that a power utility should take in response to complai
The ARRL Lab received a report of interference from a Class D audio amplifier that had been installed about 500 feet from an amateur. We purchased a set of them, set them up in our C63.4 conducted-em
