Hijackers using call signs such as "Cucumber", "Radio Millimeter", "Green Goat", "Fortune", and others, would overpower the signal on relay stations for wired radio networks to transmit their programming, or transmit into wired radio networks during gaps in normal programming. Even though the incidents appear to have been fairly common according to reports from the BBC, most were not publicly acknowledged for policy reasons. Reports in newspapers typically referred to the hijackers as "radio hooligans broadcasting drivel, rudeness, vulgarity, uncensored expressions, and trashy music". State news organizations also attempted smear campaigns against such pirate broadcasters, claiming that they had interfered with a state frequency used by Aeroflot, "preventing a doctor in an air ambulance from transmitting information about a patient".
