Submission + - Mysterious Russian 'Buzzer' broadcast changes (wired.co.uk) 1
Lanxon writes: The output of a mysterious radio station in Russia, which has been broadcasting the same monotonous signal almost continuously for 20 years, has suddenly changed, reports Wired. Numbers stations are shortwave radio stations that broadcast computer-generated voices reading numbers, words, letters or Morse code. Their purpose has never been uncovered, but evidence from spy cases suggests that they're used to broadcast coded information to secret agents. However, over the past week or so, the output of one particular station that broadcasts from near Povarovo, Russia, increased dramatically.
