Keeping my Ham Radio interests out of this discussion... If there is a conflict between two incompatible uses of the HF spectrum, I would think that it is necessary for the ITU to arrange a proper discussion regarding the merits of radio-communications vs.. PLT/Home Plug. Even though I know which I think is most important, I can see that, if it is necessary for the good of humanity, to supplant radio communications in the HF band with PLT then it will show as such in any rigorous cost benefit analysis. All we need is a body with a charter from the worlds governments to arrange this and make a ruling on future spectrum use based upon the result. Without a "cost benefit analysis", the argument will continue. In my view it is undemocratic to continue in the current manner. Regards Tim Comment on notching. Even if I am advantaged by the notching of the PLT emissions, what about the users of the rest of the bands? Do they deserve to loose their use of the HF spectrum to PLT just because they do not have an organised voice in the same way that Hams do?
