SmoothFM’s run as king of the Sydney FM stations has come to an abrupt end, while on the AM band 702 ABC Sydney has turned in a stellar performance in the latest radio ratings. SmoothFM clung to top spot for two ratings periods but has once again ceded the crown to KIIS1065, home to Kyle Sandilands and Jackie Henderson. 2DayFM’s woes show no sign of turning the corner with the station slumping half a ratings point to 3.4 overall.
