Re: ARLA/CLUSTER: Petição para banir o PLC no Reino Unido.

[Hugo Barata]

Boas a todos.Eu tentei assinar a petição mas deu erro porque parece ser só
para residentes na Inglaterra.No entanto como sou membro no UKQRM já
coloquei a questão ao Mike que me apareceu no registo da petição e estou a
espera da resposta.No entanto podendo estar a fazer um erro na inserção dos
dados se alguem conseguir assinar a petição e que não dê erro que diga
algo.Todos contra o PLC enquanto não haver compatibilidade electromagnetica
com a onda curta.Obrigado.
