Radio Forth was launched on 22 January 1975 by current chairman Richard Findlay. His opening speech included "This, for the very first time is Radio Forth". Steve Hamilton was the first on-air presenter, hosting the breakfast show. In 1990, Forth was forced to create a new station on its AM frequency. Before this, Radio Forth was broadcast as a single station on both FM and AM frequencies. The FM station was renamed Radio Forth RFM (later simplified to Forth FM) with Donny Hughes broadcasting the first Breakfast Show from the newly revamped Studio F in Forth House. The new AM station became "Max AM" which was later renamed
Forth AM to match its sister station. In 2000, both stations were relaunched as
97.3 Forth One and
1548 Forth 2. Forth 2 was redesigned as an adult contemporary music station while Forth One continued to play Top 40 songs for the 35s and under. Radio Forth was owned by Scottish Radio Holdings until 3 June 2005 when British media group
EMAP took over. In January 2008, EMAP Radio was sold to Bauer and the radio division was renamed
Bauer Radio. Ownership changes have led to more networked programming on the station. On Friday 17 June 2022, Forth 1 broadcast from their studios at Forth House for the final time. During the breakfast show at 7.45 the station played a farewell montage before walking to their new studios at
St James Quarter where the first link was broadcast just after 8am. The first song played from the new studios was 'New Emotion' by
The Time Frequency. On 6 January 2025, Forth 1’s breakfast show expanded, replacing MFR, Northsound 1 and Tay FM’s separate local breakfast shows. ==Programming==
