Aqui vai mais um artigo relativo à praga do PLC.. Simples e sem rodeios..

Vai em inglês. Desculpas aos colegas que não dominam o idioma. Se
alguém quiser traduzir para português, talvez não fosse má ideia.

Após ler o artigo, considero também que a melhor abordagem para este
problema, será pôr de parte toda a conversa técnica e assumir a
realidade. A tecnologia PLC/PLT/BPL não é compatível com os restantes
serviços que utilizam o espectro de HF. Noutros segmentos, UHF, SHF,
talvez..

Por mais que tente, não consigo encontrar desculpas (ou
justificações..?) para as administrações de países ditos civilizados
continuarem a pactuar com os interesses económicos e de marketing das
empresas que fabricam e comercializam estes produtos.

Num futuro, talvez tenhamos que nos isolar do mundo dito civilizado e
industrializado, se quisermos continuar a utilizar o espectro de HF
para as nossas comunicações..

New PLT Product Brings HF Doom A Step Closer

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?



Cumprimentos,
