Miami ? Airline pilots departing from Miami International Airport are getting an earful of something unexpected: Hip-hop tunes from a pirate radio station that sometimes interfere with their communications with the control tower.

The music comes on a pair of frequencies from a station that calls itself Da Streetz.

Authorities traced the signals to an antenna at a nearby warehouse but did not find the disc jockey, although they did confiscate equipment including three computers and a CD player.

Despite that discovery and the seizures, the broadcasts have continued, authorities said.
