Over the years, the station successfully hosted a wide variety of programmes including soap operas, local and international news, educational documentaries such as the School Broadcasting Unit's show, which aired around 10a.m.
The station's announcers included June Gonsalves, Barbara Assoon, Glen Antoine, Sam Ghany, Val Douglas, Russell Winston, Trevor McDonald, Errol Chevalier, David Evelyn, Patrick Mathura, Peter Minshall, Don Proudfoot, Bob Gittens and Ashton Chambers.
Two of the most popular programmes were: Among other regular features were the Cook Caribbean Jazz programme (which took its name from a Trinidad recording company, Cook Caribbean, that originally produced 78rpm records and later continued with the 331⁄3 format), and The Indian Hour at 6 p.m. every day.
The format (inspirational music and Christian broadcasting) of the AM frequency has now been vested in a new station, operating at 99.5 FM.
Like the old Radio Trinidad, the FM stations are currently located at the Guardian building in Port of Spain named Sky 99.5
