The broadcast studios were located in the capital city of Plymouth, with the transmission site at O'Garro's on the southern slopes of the Soufriere Hills volcano near Morris.

Radio Antilles' transmitter site was badly damaged by Hurricane Hugo, rebuilt in 1992, and then shut down and abandoned at the start of the volcanic eruptions in 1995.

Both the studio and the transmitter site were eventually burned and buried completely by lava and pyroclastic flow deposits.

Following Deutsche Welle's involvement, a satellite downlink station enabled international broadcasters to use airtime on the 930 kHz transmitter.

Radio Canada International began relays in January 1984 followed by Voice of America in 1985 and BBC World Service in 1986.
