“But, seems to me that this isn’t really carrier current as intended, rather, it’s a long wire antenna.”
Define the difference in the result of that signal emission in a leaky coax arrangement to loading a neutral line while meeting both field strength measurement limits. Better yet, define the difference in “intended” between them as well.
It is really carrier current. Where it seems to you for the confusion is that carrier current only applies to injecting RF energy onto the hot wires, which hot wires are both inside buildings and spread out all over a city. So going by your confusion, coupling to the hot lines isn’t carrier current too unless there is a transformer in the way? Well I know of many electrical service runs that extend for 2 or more blocks in rural areas where those transformers are spaced by quite a distance. Does that mean its not carrier current either?
I can run a leaky coax all over New York City if I was rich enough and run an AM or an FM station and cover that whole city. Or if the grid was wired so that the neutral line was a common (continuity) conductor all over the city, that CC signal on the line would cover the whole city just as the leaky coax would. Both methods have their field strength limits in the signal emitting off that line or coax.
“Are there any definitions in the RULES that define neutral injection as an acceptable method?”
Nope. And there aren’t any definitions in the RULES that define neutral injection as an unacceptable method either.
And no where can I find any RULE that says a CC system MUST be intercepted by a transformer and cannot bypass a transformer or cannot use its own isolated ground with ground rods.
“radiate a very short distance from the line. Reception was based more on being “connected” to the line or at least being in very close proximity to the line.”
A CC system coupled to the neutral line IS radiating a very short distance from the line! 261 feet at 580khz is a long distance to you? As to being “connected” to a line, well I cant think of any more direct connection to the line than a radio’s power cord return wire plugging into a power outlet socket with this same return wire connected in the breaker box at the NEUTRAL line connected to the service drop NEUTRAL line connected to the utility pole distribution NEUTRAL line running across town, or split up and only running a few blocks.
A good way to eliminate confusion is to study the origin and history of carrier current and its intended purposes. You will find that this new CC system and mine are no different in application, installation AND intended purposes to any previous CC system.
