acompanhei ao de leve as mudanças. Nunca entendi qual foi o propósito
de baixar a potencia, para os radios de CB, nem nunca entendi a
recomendação para operar em FM. Até li uma vez em qualquer lado, que o
uso de FM era por motivos de conservação de espectro. Nunca entendi é
como é que o FM preserva mais os espectro do que o AM ou o SSB, mas
isso , os "doutores" lá da Europa e que inventaram estas leis é que
sabem. Eu não sei de nada.
<div>Talvez o abaixamento de potencia, tivesse sido propositado para
não interferirem nos PLCs...Se calhar até tenho razão.!!! Como
aconteceu com a FCC, que escondeu os relatorios demolidores sobre o
PLC, tambem na Europa gostava de ver publicados os estudos feitos sobre
o assunto, e os relatorios das autoridades dos paises.</div>

involve the increase of AM power level from 1W to <strong>4W</strong>
and for SSB from 4W PEP to <strong>12W</strong> PEP output.</font></p>

Save the Radio Spectrum! Eliminate Broadband over Power Line. Salve as
frequencias de radio. Não use a rede electrica para transmitir dados. O
PLC causa fortes interferencias noutro serviços sem voce se aperceber.
Diga não ao PLC. Proteja o ambiente<br>
