    Where did you see that? It doesn't seem to show up on GB Grid Frequency - I wonder if it was just a glitch somewhere in the internet, rather than real world.


    I did stumble on an interesting use for mains hum though - BBC News: The hum that helps to fight crime (an old story, but one I'd missed before)
