Re: ARLA/CLUSTER: Robot de vigilância transmite entre 430-448 MHz

[Carlos Mourato]

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

*420-450 MHz frequency band, which is primarily used by the federal
radiolocation service*.

*Best 73 from: regards from: CT4RK Carlos Mourato - Sines - Portugal*

 *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.*
