On June 6, 2018, the station was approved to diplex its signal from the broadcast tower of WBIX (1260) just south of Boston (right down the street from the station's 1940–1981 transmitter site) to temporarily broadcast daytime only at a power of 1,000 watts. On June 15, 2018, WMEX applied to permanently diplex with WBIX, with a proposed daytime power of 10,000 watts and nighttime power of 100 watts, along with a city of license change to Quincy. WMEX commenced on-air testing on the weekend of June 30, 2018, simulcasting WATD-FM, to keep its license alive; it intended to resume regular broadcasting in the fall of 2018 with oldies and South Shore-based news and sports. On July 3, 2018, the station applied for an STA to increase its temporary daytime power to 2,000 watts and implement the 100-watt nighttime signal. WMEX went silent on November 10, 2018, after losing its Internet feed from WATD-FM; in addition, the station's transmitter was in the process of being moved to Brockton sister station WATD (now WBMS).
