However, the groundwork had been laid for the station to gradually become a full-time service and now Radio Wales broadcasts for up to twenty hours a day.

The other main presenters for the first decade on air included Mike Flynn, who hosted a show each weekday until 1989, Vincent Kane, Noreen Bray and Alun Williams.

Outside broadcasts from different towns in Wales were also introduced, with Mike Flynn and Alun Williams hosting a weekly three-hour live show on Friday mornings.

Other early presenters included Wyn Calvin, Maureen Staffer, Sylvia Horn, G. V. Wynne Jones (Geevers), Claire Vincent, Piet Brinton, Jackie Emlyn and Princess Anne's biographer Brian Hoey.

After the closure of Radio Clwyd, local bulletins for north-east Wales continued until March 2002 - staff having moved from Mold to Wrexham in June 1998.

Most of Radio Wales' programming is produced and broadcast from the Cardiff headquarters with the Adam Walton show originating from the BBC's Wrexham studios on the Glyndŵr University campus.

Radio Wales Sport is broadcast on Saturdays, generally between 14:00 and 19:00, during the football and rugby seasons (the programme is extended on occasions to include live commentary of early and late matches).

This transmitter was originally built to cover southern Wales and most of the West Country, and has a far greater coverage than its intended transmission area.

From 1999 onwards, the BBC was able to start creating an FM network for Radio Wales, including a 120 kW ERP transmitter near Aberystwyth.

On 24 October 2018, the station increased its FM coverage in North East and Mid Wales by taking over 32 transmitters previously used by BBC Radio 3.
