Audio Sample
One Beep, Two Beeps is a nickname given to an unidentified signal transmitting a series of beeps. This signal has been newly discovered by Jeramy Carullo and Curt Rowlett.

This signal transmits a series of 760 HzHertz (Hz), unit of frequency, defined as one cycle per second (1 Hz). beeps in a pattern, and sometimes encoded messages. One Beep Two Beeps has been heard only 3 times. More and more information is gathered about this signal through analyzing and monitoring.
