The conclusion of the federal election might explain a shift in the latest radio ratings, with Sydney viewers generally tuning from news and talk-oriented stations to light or more music-based fare.

Monday's Neilson radio ratings showed a drop in overall ratings for ABC702 and 2GB (down 1.7 per cent and 0.9 per cent respectively). 2GB retained its position at the top of the Sydney ratings, with 12.1 per cent of listeners, but ABC 702 dropped from second to third place, holding on to 8.4 per cent.

2Day-FM rose 1.4 percentage points to take second place, with 9.5 per cent of listeners.

Radio National and News Radio both lost 0.3 percentage points, with 2.4 and 1.8 per cent of listeners respectively.

2DayFM must have mixed feelings about the 1.3 per cent ratings boost enjoyed by Kyle and Jackie O Show. The duo of Kyle Sandilands and Jackie O on Friday announced they will be leaving the station on November 29. The latest ratings show they have 11.2 per cent of Sydney listeners.

ABC 702's breakfast show, hosted by Adam Spencer - who is also soon to sign off from the station - lost 0.9 percentage points, giving it a 10.9 per cent share of Sydney listeners.

Over on 2GB, Alan Jones remains king of Sydney breakfast radio, despite dropping 0.7 percentage points. His audience share sat at 16.2 per cent.

Nova96.9, which climbed 0.2 per cent to claim 7.8 per cent, retained its fourth-place spot.

Smoothfm continued to rise, with a jump of 0.7 per cent in ratings figures to snatch fifth place from WSFM, which dropped 0.2 per cent.

Smoothfm's biggest rise was in the evening timeslot, where it jumped 2.6 per cent to claim 9.5 per cent of listeners. In the previous ratings period it also rose 2.6 per cent.

That seems to have been at the expense of ABC702's evening show, hosted by Dom Knight, which fell 2.8 per cent.

There is one more radio survey period left in 2013, with results due on December 10.
