A mysterious shortwave signal is broadcasting an eerie buzz, but nobody knows why

The mysterious sound repeats at a rate of 25 times a minute, broken only by the occasional live Russian voice transmission.

The earliest known recording has been dated to 1982, and many theories have been proposed since then.
