666 ABC also fell further down the ladder overall, losing its No.2 spot to MIX 106.3, which increased its share by 4.5 percentage points. By contrast, 666 lost 0.9 of a percentage share, pushing it into third spot.

The latest Nielsen radio ratings represent a massive win for FM 104.7, which won the overall ratings as well as all but one of the timeslots across the listening audiences.

Fresh from being voted the third most-liked thing about Canberra, Scotty and Nige also toppled 666 ABC's Solly from the top position in the crucial breakfast slot.

Solly has dominated the breakfast ratings for several years but in the latest round was a distant second to Scotty and Nige, who had 22.5 per cent of the audience (up from 18.7 per cent) compared to Solly's 17.9 per cent (down from 19.3 per cent).

104.7's sister station 106.3 also made massive gains in breakfast, with presenters Rod and Biggzy increasing its share from 7.6 per cent to 14.1 per cent since the last ratings were released in September.

The overall ratings had 104.7 with a 23.9 per cent share followed by MIX 106.3 (16.8 per cent), 666 ABC Canberra (14 per cent), 2JJJ (8.4 per cent), ABCFM (7.1 per cent), Radio National (6.9 per cent), 2CA (6.8 per cent), 2CC (6.7 per cent) and News Radio (4.1 per cent).

The only timeslot 104.7 didn't win was evenings (7pm to midnight), which it narrowly lost by 0.1 of a percentage point to 666 ABC (15.1 per cent).

Canberra FM Radio content director Drew Chapman attributed the growth at MIX 106.3 to a grassroots campaign to be deliberately involved in as many community events as possible, from a school fete to the Canberra Centenary celebrations.

“This result is the absolute highlight of an already very big year and is really down to the hard work, commitment and consistency of those who work for our stations every day," Mr Chapman said.

“We've pushed MIX 106.3, particularly Rod and Biggzy, right out into people's communities and they've made some very strong connections, while 104.7 just continues to build on a legacy of consistency, with Scotty and Nige claiming the number 1 spot in breakfast, and still delivering massive events such as Skyfire."

In a statement, 666 ABC management put a positive spin on the losses, saying it had maintained its position as the ‘‘number one talkback station in Canberra in a survey that largely favoured music stations’’.

The statement said while ‘‘small drops are disappointing, they also provide a challenge’’.

666 ABC Canberra had also maintained its core 40-plus audience for the period and had increased its 55-plus share of the market.

ABC local content manager Andrea Ho also referred to the new lineup at 666 which ‘‘in a few short weeks is settling in well and already starting to show dividends in this survey’’.

The ratings for the morning and afternoon shifts at 666 did increase from the last survey, but the drive ratings fell.

“We take all survey results in our stride as just one measure of our work: to inform and engage Canberrans,’’ Ms Ho said.

“At 666 ABC Canberra we take a long-term view of both pleasing listeners and developing our people.

“I’m very proud of the hard-working team at 666. We’re grateful for the continued support of Canberra listeners.”
