I’ve occasionally noticed static playing over speakers in roughly the same rhythm: a quarter note and three triplets. Deeeeet dit-dit-dit dit-dit-dit dit-dit-dit. At first I thought it was something wrong with my PC speakers or sound card. But I’ve also heard it over the headphones while waiting to go live at a professional radio station. And I heard it over the speakers in the back of a London cab yesterday.

Deeeeet dit-dit-dit dit-dit-dit dit-dit-dit. Deeeeet dit-dit-dit dit-dit-dit dit-dit-dit.

Is this some predictable electrical noise, like a 60-cycle hum? Or is it a coded message from our equipment?
