On 19 September 2016, BBC Cymru launched a pop-up radio station, Radio Cymru Mwy (Radio Cymru More), broadcasting for three months in the run-up to the station’s 40th anniversary. Consisting of five hours of music-led entertainment programming each weekday, Radio Cymru Mwy was available on DAB in south east Wales and online.
Six months after the station closed, BBC Cymru announced it would launch a permanent second station, Radio Cymru 2. The new service airs for two hours every morning on digital and online platforms, as a music and entertainment alternative to the main network, which airs the breakfast news programme.

The daily breakfast show broadcasts from Cardiff (Monday–Saturday) and Bangor (Sundays) with short news bulletins on weekdays from Aberystwyth.
