ARLA/CLUSTER: Death of short wave imminent

[Pedro Ribeiro]

Parece-me mesmo mentira do "fools day" (neste caso), no entanto a 
realidade oficiosa não estará muito longe neste momento ou a curto prazo.

Não sei se estará em condições de acrescentar detalhes, mas ao nível 
profissional (assumo pelo email) também têm casos confirmados de 
interferências nas comunicações com origem nas tecnologias PLC/PLT?

73!
