The Morse Message (1962)
In 1962, a radio message in Morse code was transmitted from Evpatoria Planetary Radar (EPR) and directed to planet Venus. The word "MIR" (Russian: Мир, it means both "peace" and "world") was transmitted from the EPR on November 19, 1962, and the words "LENIN" (Russian: Ленин) and "SSSR" (Russian: СССР, acronym for the Soviet Union (Союз Советских Социалистических Республик)) on November 24, 1962, respectively. All three words were sent using the Morse code. In Russian, this letter is called Radio Message "MIR, LENIN, SSSR". This message is the first radio broadcast for extraterrestrial civilizations in the history of mankind, it was also used as a test for the radar station (but was not used for measuring the distance to Venus because for distance measurements the EPR uses coherent waveform with frequency manipulation): The signal reflected from surface of Venus and was received 4 minutes 32.7 seconds (Nov 19) and 4 minutes 44.7 seconds (Nov 24) later.
Now this radio message is flying to the star HD 131336  in the Libra constellation (the famous star Gliese 581, the addressee of A Message From Earth and Hello From Earth, is also located in the Libra).
