It was the first commercial radio station to broadcast on the FM band in Adelaide started by Paul Thompson of the Austereo Network. The first song played on air was "Sultans of Swing" by Dire Straits. Initially, SAFM was somewhat of a fringe operation, hampered largely by the fact that many houses, and more importantly most contemporary cars, did not have the ability to receive FM radio broadcasts. It changed its name to "SAFM" and in 1989 altered its frequency slightly to 107.1 MHz. A second frequency, 91.1 MHz, was added as what was the first of many repeater frequencies in Adelaide, required due to Adelaide's sometimes problematic television and radio reception idiosyncrasies. The frequency was later changed to 90.3 MHz and it continues to operate on that frequency. SAFM was the first station in the world to have Black Thunder promotional vehicles and the annual Australia Day Sky-Show fireworks display was an Adelaide institution for many years. Between 1984 and 1993 it was the highest rating station in Adelaide and achieving its best survey results in the late '80s, spearheaded by the "Morning Zoo" breakfast show. From its inception SAFM was an adult rock-based format, before switching to a
contemporary hit radio (CHR) format in March 1996. In November 2003, the station adopted an
adult contemporary music format, reverting to CHR in December 2004 following the launch of rival station
Nova 919. On 20 October 2014, the station was relaunched as Hit 107, but reverted to SAFM on 27 July 2020 as part of a network-wide relaunch, shifting to a "sex" Hot
adult contemporary music format in an attempt to target a 30–54-year-old audience. In October 2022, it was reported that the breakfast show Bec, Cosi and Lehmo would be axed. ==Programming==
