" Tambem não entendo qual é a guerra dos Ws!...Então esse espectro não
é atribuido aos amadores da região 2 a titulo secundário?"

Muito simples prezado colega,

Está em discussão no Congresso dos Estados Unidos a retirada TOTAL de
toda a faixa dos 70 cm, mesmo que a titulo secundário, ao Serviço de
Amador e Amador por Satelite. Com que fim ? " the creation and
maintenance of a nationwide Public Safety broadband network"! vai
dai....

 *Warning*
*Save the Radio Spectrum! Eliminate Broadband over Power Line. *
*
*
*Salve o espectro electromagnético!. Não use a rede electrica para
transmitir dados. Os "homeplugs power line" e a tecnologia "power line"
causa fortes interferencias noutro serviços sem voce se aperceber. Diga não
à tecnologia power line. Proteja o ambiente electromagnético. Utilize
tecnologia de redes sem fio, denominadas wireless.*
