Contrary to popular belief, the transmission is not related to the Dead Hand system, it has been interrupted and stopped many times yet no nuclear weapons nor ICBMs have been launched by the radio station directly. The best-supported hypothesis with the most evidence is that it is part of a military commandment network for the Leningrad Military District of Russia.
