[1] Until 31 December 1982, local radio services for Cornwall had amounted to a regional weekday breakfast show Morning Sou'West, aired on BBC Radio 4's frequencies in Devon and Cornwall, plus five-minute regional bulletins on Saturday mornings and Mondays to Saturdays at lunchtime and teatime.

This programme, along with all other late night regional programming, ended on 7 October 2023 due to BBC cutbacks, and was replaced with a networked England-wide late show which broadcasts every night of the week.

In 1987, a new weekly 15-minute-long bilingual show, Kroeder Kroghan, detailing Celtic cultural events taking place in Cornwall, was introduced.
