I think Ed (W1RFI) has cautioned us that the FCC long ago decided not to address radiated emissions below 30 MHz and that they are unlikely to do so in the future. As far as theyre concerned, the HF

What it boils down to is that 1) Rules were adopted many years ago, with the usual influence from big money. 2) Rules were based on the assumption that nothing exists other than the power line for co
re: "the FCC long ago decided not to address radiated emissions below 30 MHz " I didn't say it had to be an FCC accepted rule. I gave an example of a 'service' that has such specs. I propose somethin

Tony, In POWER line RFI issues with hams on HF bands, the only part of PART 15 that applies is the harmful interference clause. This has worked effectively for decades. So I am assuming, and I could
I was considering allies in this fight. I thought of Elon Musk but he has written off AM as an entertainment medium. He has phased out AM radios in this cars: <https://www.wsj.com/articles/your-tesla
Well, I was pretty clear that this is addressed primarily as harmful interference, irrespective of compliance with the emissions limits. The Part 15 rules do not require certification of ttis type of
Are the HFT guys (the High Frequency traders on Wall Street, you know, 'quants' et al) still testing on the HF bands, with the intent to use that medium to execute trades with less than the delays se

If you have access to a spectrum analyzer, look for spikes in the Civil Aviation Band. If you find any, report them to the FAA. They have ZERO tolerance for interference in their spectrum. Things hav

If EU's standards are the model for what we would like, should they be posted on web sites (like ARRL and our won) and be stated as "good engineering practice"? I have found in the past vendors will
Possibly, but EU has also take a tact that it also regulates immunity, which is not as good a regulatory paradigm as it might appear to be. In some countries, they decided that if they have immunity
Actually, the FCC really hasn't given up on HF. What I have said is that there are no radiated emissions limits for unintentional emitters below 30 MHz. (There are conducted limits onto the AC mains.
A solar system that uses >9 kHz would have to meet radiated emissions limits above 30 MHz and conducted limits onto the ac mains below 30 MHz. ________________________________ From: RFI <rfi-bounces@
JIm, We are in contact with Solar Edge and Tesla, the two major players. If you can summarize what you previously provided, we can make sure it gets into the hands of the engineers. Ed Thanks for you
Cooperation and coordination will almost always work out better than threats and bullying. What we have here is just one of the benefits of belonging to the primary protector of the amateur radio ser
