Let's forget the tech speak, and the engineering talk of decibels and signal levels.
Here's what is happening, in plain English:
What we are facing is the design and high-powered marketing of a whole large family of new products which cannot operate normally without ENDING SHORT WAVE RADIO, FOREVER.
Period.
It's no more technical, or esoteric than that. NO MORE SHORT WAVE. EVER. The entire HF band, 2 to 29 megahertz, JAMMED by the most highly distributed system of wideband HF noise generators EVER INVENTED. If WE do not act proactively, NOW, these will be in every building in the industrialized world.
Is that simple enough?
The latest such invention being heavily marketed, amid glowing praise in magazines, sends audio through power lines using HF carriers at a high enough power to jam the entire spectrum in a radius of hundreds or thousands of feet depending on conditions.
This particular product was tested by someone on the UKQRM list and was found to have NO NOTCHES! Amateur radio frequencies are NOT PROTECTED! This matches the experience in Portugal, where products are distributed without these notches.
Got that? No more utility. No more ham. No more use of marine USB while dockside. NO MORE SHORT WAVE RADIO, ANYWHERE IN THE INDUSTRIALIZED WORLD, EVER AGAIN.
I don't know why I bother with this cause. The apathy is complete, and the regulatory indifference is shocking. Unless a movement starts, right now, involving people who traditionally distrust political movements, it will be over. The regulatory agencies will say, well, that's the breaks. Sorry about that.
The people of this Earth will lose the most accessible and democratic (small d) communication medium ever invented. This will have a tragic effect on all history.
Now... is that clear enough?
