That's totally brilliant!! 
The piece at the end which people are interpreting as "f*ck"; I don't think is a word. Sounds more like when you rewind an audio sample. So the clip says, "Jesus Christ, help us all lord!" and then rewinds back to the start of the clip - making this sound which sounds like a word. Would make sense seeing as the audio is looping.
Very interesting indeed though. What would be worth watching is how the media etc would react if this happened on a massive world-wide scale. Would they keep claiming "Technical glitches"? If indeed it was not a glitch and instead the technology starting to fail - how far would they be able to go in order to cover it up? Could be fun to see.
The strangest part about the whole thing is how the spokesperson for the station says the audio clip was; "Jesus Christ, one of the Navarines". Because it most certainly wasn't that. Unless different people in different places heard different things...if so - that would be one very weird "glitch".
Well I am up for hearing about more of this sort of thing, that’s for sure…
