Sputnik's Beep Was Not Morse - And Why Everyone Thought It Was In October 1957 the world's radios filled with a beep from orbit. Newspapers called it a signal, a code, a message. Listening operators heard something simpler - and more moving. A heartbeat, not a message Sputnik's transmitter sent regular pulses so stations could track the satellite and study the ionosphere. The pattern never changed: no letters, no code. Its meaning was its existence - proof of orbit, heard live. The Morse comparison Beeps invite the comparison because Morse trained the world's ears. The episode says more about 1957 than 1844: after a century of keys, humanity heard machinery in the sky and reached for the oldest beeping language it knew.
