ARLA/CLUSTER: Re: Aumento do QRM na banda dos 40m devidos aos radares OTH russos

[Carlos Mourato]

Mais grave ainda é ter escutado durante horas um OTHR em 8906KHz, que é a
principal frequência da FIR oceânica Santa Maria, e fundamental para a
aviação civil que cruza o Atlântico! Durante horas esta frequência esteve
completamente inutilizada pelo metralhar de S9+20, de um OTHR não sei de
onde,
