Re: [amsat-bb] The end of daytime HF?
Why are they only installing the proper RFI suppression methods on the installations that someone complains about?
They should be putting these RFI suppressors on ALL of their installations. The cost of the necessary components must be negligible compared to the total cost of the installation. Is that modern business practice nowadays?

I have an ongoing RFI case with the solar panel manufacturer, Solar Edge. Their field engineer, Tom Simpson, has handled many RFI cases in the past so they are aware of the problem.
My case is on schedule for repair and Tom assures me that the RFI will be negligible once the proper RFI suppression methods are installed. The RFI emanates from a neighbors solar panel system about 150 feet from my home.

Unfortunately, yes. It's a big problem by me, using cheap materials from China where lip service is paid to our Codes and standards in order to carve out a profit margin without regard to the consequences. Often materials purchased for electrical work at the big box stores had supplies where the UL stamp was just a mark without the devices actually meeting the standards, and now they don't even do that. So, after the Home Depots et al have put many of the niche electrical suppliers out of business, now there's very few stores to turn too to get the good stuff anymore.
I had no idea how bad the solar panel QRM was by me until we had a hurricane knock out the local power grid for a day or so. I was delighting in the absolute quiet the blackout brought until we had dawn and then the noise started. It's really bad by me on Long Island, NY and the #1 source of cold callers are solar suppliers taking advantage of people who don't care what goes up on their roof. The biggest topic at the clubs by me and the SDR groups I follow is noise mitigation, and how we're looking for different ways to handle ever increasing levels of QRM. It certainly is a big deal for those of us seeking to get on 630 meters and lower.
I wish to thank Bob WB4APR for bringing this up, it certainly is something to rally the troops over, especially with the current attitude at the FCC.
