Carrier Current Cryptology
Posted on December 23, 2012
As reported our carrier current system is always in a test mode because of what I find to be a very hashy rule, 15.221, that besides talking about many different subjects all bunched together, becomes especially imprecise on the most important point, measuring the near field radiation for compliance.
If you have insomnia tonight, all you need is to follow this and you’ll be asleep in one minute…
(a) Carrier current systems … may operate …. provided the field strength levels of the radiated emissions do not exceed 15uV/m, as measured at a distance of 47.715/ (frequency in kHz) meters from the electric power line.
Levels? The word “levels” is plural. How can a single transmitting system produce numerous levels at a particular point in space?
Furthermore, where is “from the electric power line” The entire neighborhood is draped in power lines going everywhere.
It’s impossible to comprehend which exact power line to measure away from, because it will always be toward further power lines.
Christmas can wait. This is important.
