Tayside Sound Limited was incorporated on 27 April 1979 to set up a radio station in accordance with the then regulatory body, the Independent Broadcasting Authority.

Radio Tay commenced broadcasting on Friday 17 October 1980 from the Taybridge TV transmitter site at the southern end of the Tay Road Bridge on 95.8 MHz FM and an AM transmitter on 1161 kHz at Greenside Scalp close to the Taybridge site but located lower down, at the shoreline of the River Tay. Relay transmitters in Perth opened on 14th November 1980 - FM on 96.4 MHz from the existing Perth TV transmitter on Craigie Hill on the SE edge of the city and a new AM transmitter on 1584kHz at Friarton Road, also on the southern perimeter.

The Taybridge FM transmitter changed frequency to 102.8 MHz as part of a European agreement to reallocate FM frequencies. The 95.8 MHz having been allocated to BBC Radio 4 in Scotland.

The 102.8 MHz transmissions from Taybridge were moved to the larger Angus TV transmitter site, near Tealing , on 10 February 1994. The Taybridge transmitter became a relay site and changed to the same frequency as the Perth relay transmitter (96.4 MHz)

Originally launched as a simulcast station on AM and FM, Radio Tay split into two distinct radio services on 9 January 1995: Tay FM, playing contemporary hit music and Tay AM, carrying an older selection of classic hits.
