The station began operations in 1976 as MRS 97.5, airing an adult contemporary format. In 1998, after NBC was acquired by PLDT subsidiary MediaQuest Holdings, the station rebranded as Anna @ Rhythms 97.5 (later on shortened to Anna 97.5 in 2005) and switched to a Top 40 format. In 2009, it rebranded as WAV FM. On February 21, 2011, months after TV5 took over operations, the station became a relay of Radyo5 92.3 News FM. On November 4, 2024, its originating station transitioned to 92.3 FM Radio Manila following an agreement for Philippine Collective Media Corporation (PCMC) to acquire most of NBC's radio assets and frequencies, excluding those in Cebu and Cagayan de Oro.[3][4][5]
