Learning of Hertz's work, in 1895 Popov constructed an apparatus that could register electrical disturbances due to lightning. He applied it for receiving man-made signals. In 1896, he demonstrated a radiotelegraph system which transmitted Morse code. In Feb 1904, Popov first demonstrated radio transmission of the human voice. His invention was first used by the Russian navy. However, Russia's first radio factory was established by the Marconi company.
