I think we can agree also that any communication system that uses the ether should be classified as an intentional radiator (see ITU). If this usage of the ether is unintentional (=actual) due to an intentional choice of an unsuitable interconnection medium (mains power wiring), one may doubt to the level of unintentionally - ism. I think we can also agree that the mains wiring is not a suitable medium for transmission of HF and RF signals. And the high level of transmission required and requested (and reason for the interference) by the PLT industry is partly because the transmission medium is so unsuitable for this purpose. Did anyone say good craftsmanship ?

I think we can agree that the radiation from PLT-energized cables is not intentional. But 'intention' and 'actuality' are not the same. What matters for EMC is whether the installation actually radiates or not, regardless of whether it is intended to or not. What is it that is 'paved with good intentions'?(;-) -- OOO - Own Opinions Only.
