Still a hot favourite of radio buffs in and around central Kerala, the station began its broadcast on November 1, the state formation day, in 1989.
Though a large number of private players have entered the field, the public broadcaster is far ahead in terms of revenue and popularity, AIR officials said.
The Kochi FM station is now gearing up to mark the jubilee by launching a number of new programmes, Station Director Balakrishnan Koyyal said.
An audio-history of Kochi, a 'kathaprasangam' series, a 'kavyasandhya', a folk fest, and a seminar on women issues are on the cards to mark the occasion, he said.

A get-together of all the staff of the Kochi station, including retired broadcasters will be held at the AIR campus in Thrikkakara in Kochi on November 1, he said.
He said though private FM stations posed challenges, the Kochi FM could retain its traditional audience and caught the attention of youth through quality content.
Sreekumar Mukhathala, a programme executive of the station, said Kochi FM caters to the interest of all kinds of audience, be it high-profile, downtrodden or youth.
"Private FMs have their limitations. They have to pay more attention to their profit. But as a public broadcaster, we can give more priority to the interests of our audience. It is the main reason behind the success saga of our FM station," he told PTI.
In addition to the major programme zone of Ernakulam district, AIR's Kochi FM is available in Pathanamthitta, Palakkad, Idukki, Alappuzha, and major parts of Kottayam, he added.
