The Federal Communications Commission assigned this station the call letters WAQW on February 7, 1997.[1] This designation was short-lived as the station switched to the current WMNG call letters on September 26, 1997.[1]
Construction permit
WMNG is currently a class A station broadcasting with 6,000 watts of effective radiated power in a non-directional pattern from an antenna 213 meters above the average terrain. On September 20, 2007 they applied to become a more powerful class B station broadcasting with 30,000 watts of effective radiated power from a directional antenna 230 meters in height above average terrain.[4] The proposed new pattern will protect Puerto Rico from interference by this station's broadcast signal. A construction permit authorizing these changes was granted by the FCC on October 14, 2008, and is set to expire on October 14, 2011, if the upgrade is not completed.[5]
