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. on Mondays to Fridays when school was in session, and "The Passing Parade" hosted by John Doremus. The station's announcers included June Gonsalves, Barbara Assoon, Glen Antoine, Sam Ghany, Ken Laughlin, Hugh Blackman, Larry Heywood, Val Douglas, Russell Winston, Trevor McDonald, Holly Betaudier, Peter Minshall, Don Proudfoot, Bob Gittens and Raffie Knowles.
Two of the most popular programmes were:
- "Sunday Serenade", a show that featured performers of the day including the Mighty Sparrow and Ken Hutcheon), broadcast at noon on Sundays co-hosted by Bob Gittens and Sam Ghany.
- "Auntie Kay", a children's talent show named after its presenter Kathleen Davis, which ran on Sundays at 2.00pm and was sponsored by the Bermudez Biscuit Company. The back-up band was Choy Aming and the featured pianists were Aldwyn Albino and Dawlett Ahee.
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 6:00 pm every day. There was also a programme for children called "Tell Me a Story" with Auntie Wendy, and a classical music show entitled "Music of the Masters".
Radio Trinidad covered the many events linked with the thoroughbred horse breeding fostered by Trinidad and Tobago: horse races at the Queen's Park Savannah, in Port of Spain, at the Arima Race Track, at Union Park in San Fernando and at Shirvan Park on Tobago, and aired live commentary on races in Barbados. The main race and sporting commentator was Ralph Ellis Knowles, better known as Raffie Knowles, who was Head of Sports at the station for years. (When television came to Trinidad on Independence Day in 1962, he moonlighted there as Trinidad and Tobago Television's main sportscaster. Raffie's photographic memory enabled him to work without benefit of script or teleprompter, providing detailed scores, giving historical data and anecdotes on players and teams on a whole variety of sports and sporting personalities.)
A sister station at 95 FM was officially launched in 1976; prior to that 95 FM merely broadcast the same programming as Radio Trinidad.
