The network started recruiting both experienced and new employees including a new generation of Radyo Patrol Reporters. Their studios were initially located at the Chronicle Building in Pasig (where Benpres Corporation is currently located). After days of careful planning and a period of test broadcast which took place from July 16–21, 1986 (alongside DWKO-FM 101.9, which started broadcasting and the network's mother TV station ABS-CBN Channel 2, which re-opened on September 14), DZMM officially signed on the air with the new tagline ""Ang Himpilan ng Malayang Mamamayan"" (Station of the Independent People) on the afternoon of July 22, 1986 at 3 pm.
