WRHC (branded as Cadena Azul, meaning "Blue Network") is an AM radio station broadcasting on 1550 kHz with a Spanish variety radio format. Licensed to serve Doral, Florida, United States, the station reaches the Miami metropolitan area. The station is currently owned by WRHC Broadcasting Corp.[1]

The station's name and broadcast callsign are an homage to the former Cuban radio network, RHC-Cadena Azul, which operated from 1939 until 1954.[2]

Previously known as WRIZ until 1985, the station had a phased array of four radio towers in Stiltsville south of Key Biscayne from 1967 to 1990.[3] Because salt water is highly conductive, it makes an excellent ground plane for signals in the mediumwave radio band, allowing the station to travel farther on the same power, although this station's purpose was to put a strong signal across Miami while minimizing its signal toward the Bahamas Islands and a station on 1540.. As with all medium-frequency stations, the towers themselves were mast radiators, connected to the transmitter shack via transmission lines, held in this case a few feet above the water line by pilings.
