Re: ARLA/CLUSTER: China lança satélites "GPS" na banda dos 23cm

[Carlos Mourato]

Porra!!!!Eu que nem posso ouvir falar em MEO, agora até os vou ter a voar
sobre a cabeça???...É que ontem fui de novo bafejado pela sorte, e nasceu
mais um PLC a fazer QRM dos 9 aos 35 MHz, com 9+20...Será que este martirio
não termina nunca?
Como é lógico, imediatamente seguiu reclamação.

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
