Maybe so, but many an electric utility company whose noise has been well below S9+30 dB has received correspondence from ARRL, then from Riley. See http://www.arrl.org/tis/info/HTML/plc/FCC_enforceme

Hi, guys and gals, Well, it was me that done it, with the help of 160,000 hams who have helped make sure ARRL has resources to do this sort of thing. Thanks to all who helped make it happen. I couldn

So far, from our best info, about 60% of the cases are resolved. A few are poised to go to more rigorous enforcement steps, but that needs to be done absolutely flawlessly, at least for the first few

Glad to hear it. You are one of the 60%. Five years ago, had anyone said that anyone could make a 60% dent in the power line noise problem, it would have seemed an impossible dream. Like a chess game

The sole claims to the lack of interference problems are that they comply with Part 15 (Part 15 = S9 noise on HF, under typical circumstances) and that they have had no reports of interference. The

I looked into it, and it looks like a mareketing conference. It would have cost ARRL over a grand, with travel and the conference costs. I decided to spend the members' money somewhere else. :-) 73,

Then I have to wonder what you may have heard that you thought was BPL, Mike. The signals recorded in test area #1 were recorded while the involved amateur's BPL modem was downloading a streaming vi

For the most part, this industry has been very tight lipped about BPL trials and their specific locations. When I told the folks in Potomac that I was going to their system to check its interference

Mike is sincere in his beliefs. He has looked at only one system, and is drawing his conclusions from what he has seen. He may be proven incorect, but his post was not a troll; it was intended to be

Do I presume you have downloaded the ARRL video? Those "several narrowband inside noise sources" seen in test area #4 are better desrcribed as "several hundred." Those birdies are spaced about every

I have thought of a few more points to add. In test area #1, the system is "HomePlug" notched. This system has little energy in the ham bands, except for the new allocation at 5.3 MHz. In that area,

I converted the video to a .wav file and ran it through an oscilloscope to get a signature. A bit of audio clipping somewhere in the process, but the signature is clearly not sparking. http://www.ar

To date, DSL has not caused hams any problems, but it stops a 1.1 MHz, though it will soon be going higher. But twisted-pair telephone wiring is a much poorer antenna than overhead power lines, so th

There are a number of BLP architectures. Some use fiber to get signals to a neighborhood, then a combination of the medium voltage lines on the poles and the low voltage lines in the house to get to

Yeah, but infrastructure is still required. In some cases, the power company has to run fiber to the neighborhood. In others, they use the MV lines, but have to put digital repeaters about every 2000
