Radio 531

Radio 531 is one of Adelaide, Australia's two "on band" dedicated non-English language commercial radio services. 531 broadcasts an Adelaide based Italian language radio service.

The radio station was established in the 1990s (exact date and circumstances required), and commenced transmissions under a Australian Broadcasting Authority Temporary Community Broadcasting License (TCBL). The broadcasts on 93.7 FM were time shared with youth/dance community radio station Fresh FM, and in the licensing process both organisations applied for the full time permanent FM broadcasting license.

While Fresh FM was ultimately successful in gaining its license, this left the Italian Language station without a frequency. In the months following the grant of the FM community license to Fresh FM, an additional AM license became available. This license was to be issued on a frequency which became available upon the previous licensee 5UV (Radio Adelaide) moving to an FM frequency.

531 AM was auctioned by the Australian Broadcasting Authority for use as a narrowcast service, and the final and successful bid ($400,000 on 27/11/2002) was won by "Radio Televisione Italiana (SA) Inc", and the station is licensed as 5RTI.
