History 1963 - 1986: Boss Radio In 1963, the 17-year-old Ramon "RJ" Jacinto started operating the station in the backyard of his house together with his classmates from Ateneo. Originally broadcast on the frequency of 770 kHz, it carried the tagline, "DzRJ: Boss Radio", which later evolved into "DzRJ, The Rock of Manila" as it hosted a daily show called "Pinoy Rock 'n' Rhythm" (later shortened to "Pinoy Rock"), which was conceived by DzRJ's original station manager, Alan Austria ("Double-A") and its program director, Emil Quinto ("Charlie Brown").

The earliest contributions were from groups such as Maria Cafra ("Kamusta Mga Kaibigan"/"How Are You, Friends?"), Petrified Anthem ("Drinking Wine"), Destiny ("A Taste Of Honey"), and the nascent Apolinario Mabini Hiking Society. A mobile recording studio was set up by Alan Austria in 1974, using the station's 4-track tape recorder and mixing board, for "live-in-the-booth" recordings to facilitate the entries of contestants for one of its sponsors, RC Cola and its First National Battle of the Bands (produced by RC Cola's then COO, Cesare Syjuco). More than 200 new songs were said to have been recorded for the Pinoy Rock 'n' Rhythm show, and these entries were aired in succession through many weeks, as the participating bands worked their way into the elimination rounds. These demos paved the way for recording artists such as Florante, Heber Bartolome of Banyuhay, Johnny Alegre of Hourglass, Bob Aves of Destiny, and many others, who thrived prominently in the Philippine record industry during later years. DzRJ's premises, the J&T Building, was the site for rock concerts which were
