Re: ARLA/CLUSTER: PLC `s já interferem dos 50 aos 300 MHz

[Carlos Mourato]

Isto assim agora já pia finiho!!!!...existem satélites bem sensiveis aos
sinais mais fracos, como por exemplo a série COSPAS SAT, de socorro, que
conseguia captar uma harmónica de menos de 1 mW, em 121.500 KHz que era
emitida por uma emissor la no batente, (20 X 6075 KHz), e tivemos graves
problemas com essa QRG por isso!...Não estou a ver essa porcaria a fazer QRM
pela banda da aviação civil, até porque nessas frequencias o alvcance pode
ser muito grande com pequenas potencias...Alguem tem que parar esses
"parvalhões" que julgam que o espectro radioeléctrico é so deles!!!

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
