In 2013, Viva South acquired the franchise of Ultimate Entertainment Inc., prompting Mango Radio to move its broadcasts online.

In January 2015, the station went back on air as Oomph Radio with a CHR/Top 40 format.

In June 2016, the station rebranded back to UR97 and added 70s, 80s and 90s to its playlist, despite retaining its format.

In February 2017, the Oomph Radio brand was retired once again due to management decision.
