The notion of a sector-wide broadcast is patently ridiculous anyway. Real life radio broadcasts cover thousands of square miles, and yet, you have to be tuned in to hear them. New blogs and news articles hit the internet every second, but you won't find them unless you actively go searching for them, or you've subscribed to a feed. Even then, that feed won't have everything.
Similarly, you have to be logged into the forum and looking for broadcast comms threads to find stuff like this. It's not really Sirius-wide; it's just whoever cares to read it, which is, incidentally, hardly anybody at all. This is an unhinged college radio DJ screaming into the void, not some Emergency Broadcast System message that overrides normal public programming.
A way a lone a last a loved a long the riverrun, past Eve and Adam's, from swerve of shore to bend of bay,
brings us by a commodius vicus of recirculation back to Howth Castle and Environs.
