WKOX (1430 kHz, "Buenas Nuevas Boston") is a commercial AM radio station owned by the Delmarva Educational Association. It broadcasts a Spanish Christian format. The station is licensed to Everett, Massachusetts and targets Boston and its suburbs. It broadcasts from radio studios in Medford. The transmitter site is also in Medford at a separate location. History The station signed on January 20, 1952, as WHIL, a daytime-only station based in Medford, Massachusetts. After an attempt to program pop music, the station flipped to country music in the 1960s, and added an FM station, WHIL-FM 107.9, which simulcast the AM during the day and continued with similar programming at night. In 1972, the FM was changed from WHIL-FM to WWEL-FM, and both stations switched to a format of instrumental versions of pop hits and show tunes known as beautiful music, with the stations simulcast most of the day. A couple of years later, WHIL became WWEL, to match the FM station's call sign. In early 1979, after the stations were sold, the call letters were changed to WXKS and WXKS-FM, with the "KS" in the call letters representing the word "Kiss". Both stations launched a disco format (mostly, but not completely, simulcast), with the FM (Kiss 108) soon becoming one of Boston's most popular radio stations, although the AM had very few listeners. The FM side eventually made a very successful transition from disco to mainstream top 40; by that time, however, the AM no longer had the same format as the FM. From December 1979 until late 2004, WXKS was an adult standards-format station, which at first carried the Music of Your Life format, with the music played by local personalities. For a time in the 1980s, WXKS became quite successful, especially among older listeners, in spite of its daytime status. Later, WXKS went to 24-hours-a-day operation and broadcast programming from both the Music of Your Life and AM Only/America's Best Music satellite networks, along with a local morning show during the early 2000s. In late 2004, WXKS made a format change to liberal talk, for the most part carrying programming from the Air America radio network. Since the WXKS nighttime signal is very directional, sister station 1200 WKOX in Framingham also broadcast the same programming. At noon on December 21, 2006, the stations dropped the progressive talk format in favor of a Spanish tropical format called "Rumba." On September
