2006-2022: The Edge Radio
The Edge Radio began airing in 2006 at 90.3 FM in Lucena, when the UCB formed a partnership with Century Broadcasting Network.

The Century-owned Edge Radio stations were later sold to and spun-off into Christian Music Power (CMPI), a broadcast franchisee of UCB in the Philippines.

In May 2013, one of the station's presenters and a blocktimer, Melinda Jennifer Glefonea, was reportedly abducted by 2 unidentified men at a restaurant in the town's proper. However, Quezon police authorities found out that her abduction/kidnapping was actually a set-up by Glefonea herself as she told to the police.
