About Three D Radio

Three D Radio

Three D Radio (callsign 5DDD) is a community radio station based in St Peters, Adelaide, South Australia, broadcasting contemporary, progressive and alternative music on 93.7 MHz FM across Adelaide. Established in 1979 as 5MMM, it sold its Triple M callsign to Village Roadshow in the early 1990s and became Three D Radio on 1 October 1993. Run entirely by volunteers with no paid staff, it airs over 60 diverse programs each week to a cumulative audience of over 110,000 listeners — with no playlists, but strict quotas: at least 40% Australian music (half South Australian, a quarter unsigned) and a quarter from female artists. It is operated by the Progressive Music Broadcasting Association (PMBA) and funded by listener contributions and grants. The station's website is https://www.threedradio.com/.

Overview

Three D Radio is Adelaide's alternative music station: the volunteer-powered 93.7 FM for the progressive, the local, the under-represented — the station with links to the late-70s subscriber-based community radio surge, alongside Melbourne's Triple R and Brisbane's 4ZZZ. Where the commercials playlist the hits, Three D has no playlists: the announcers choose, the quotas ensure the Australian, the South Australian, the unsigned, the female artists get heard. It supports "the local music and arts community in a way that few other Adelaide radio stations do."

History

The callsign journey — 5MMM to 5DDD — is the station's signature story: the Triple M letters, sold to the commercials; the Three D name, born from the deal. The 1 October 1993 date — the official rebirth — is the birthday: the alternative station, renamed. The cash injection — the undisclosed Village Roadshow payment — was the irony: the commercials' money, funding the alternative's equipment.
The volunteer model — 'run by volunteers, with no paid staff' — is the purest community radio: the announcers, the technicians, the committee, all unpaid. The funding — 'contributions made by its listeners and grants,' the 'very occasional grant' — is the shoestring: the subscribers, the supporters, the survival. The 45-plus years — 1979 to today — are the endurance: the idealists' station, still idealistic.
The 1979 founding — the 5MMM Triple M — was the community radio surge: the subscriber-based stations, the late-seventies idealism, the Adelaide crew alongside Melbourne's Triple R and Brisbane's 4ZZZ. The Double J impetus — the ABC's Sydney experiment, 'embraced by the rock culture so strongly and immediately' — fuelled it: the progressive times, the alternative need. The Village Roadshow deal — the early 1990s, the Triple M callsign sold — was the windfall: the undisclosed sum, the modern equipment, the running costs secured.

The station was established in 1979 as 5MMM — Triple M — part of the national late-70s community radio wave. In the early 1990s, Village Roadshow purchased the Triple M callsign for its national network; the undisclosed cash injection funded modern equipment and running costs. The station changed its name to Three D Radio on 1 October 1993 (the 5MMM callsign going to the commercial 5KKA, now Triple M Adelaide). The transmitter is at Summit Road, Crafers (EIRP 10,332 watts), broadcasting across metropolitan Adelaide and surrounding rural areas.

St Peters — the inner-east suburb — is the station's home: the PMBA's base, the volunteers' studios. The Crafers transmitter — Summit Road, 10,332 watts EIRP — covers the metro and the rural fringe: the city, the hills, the plains. The 60-plus weekly programs — the volunteers' shows — are the content: the contemporary, the progressive, the alternative, the local. The 110,000 cume — the average cumulative audience — is the proof: the alternative, with an audience.
The announcers — the volunteers, the music lovers — are the station: the presenters choosing their own music, the quotas ensuring the balance. The listeners — the contributors, the subscribers — fund it: the community's money, the community's station. The grants — the 'very occasional' — supplement: the sector's support, the survival.

Programming

Three D Radio airs over 60 diverse programs each week: The Sound of Muesli, Shattered, Sunday Rise, 4 Course Breakfast, The Sunday Sleep In, Reverb, Revolution, Roots & Branches, Strange Rampage, Jazz Voice and more. There are no formal playlists — announcers are free to choose — but the quotas are strict: at least 40% Australian music, of which half is South Australian releases and a quarter unsigned material; another quarter from female artists, historically under-represented in broadcast music.

The local music mission — 'support the local music and arts community in a way that few other Adelaide radio stations do' — is the station's gift: the SA releases, the unsigned bands, the gig guides, the airplay the commercials won't give. The female-artist quota — the quarter, the under-represented centred — is the corrective: the broadcast music's gender gap, addressed on 93.7. The audience — the 110,000, the alternative community — is the proof: the quotas, the freedom, the music, working.

Coverage & Audience

Three D Radio broadcasts on 93.7 MHz FM (5DDD) from Crafers across greater Adelaide and surrounding rural areas, streaming live via its website. The average cumulative audience exceeds 110,000 listeners — the alternative music community, the local arts scene, the listeners the commercials don't serve.

The quota system — the 40% Australian, the half-SA, the quarter-unsigned, the quarter-female — is the station's ethics in numbers: the local music, mandated; the women artists, centred. The no-playlist rule — the announcers' freedom — is the trust: the volunteers, choosing; the quotas, guiding. The PMBA — the Progressive Music Broadcasting Association — is the governance: the members, the progressives, the music.
The St Peters base — the inner-east studios — is the volunteers' home: the PMBA's rooms, the 60 shows' birthplace. The ACMA record — Station ID 1600483, licence 1385198-1, authorised 4 August 1988 — is the official footprint: the community licence, the 93.7 frequency, the 5DDD callsign. The website — threedradio.com, the TuneIn stream — is the digital front door: the alternative, online.

Ownership

Three D Radio is run by the PMBA — the Progressive Music Broadcasting Association — a community-based, volunteer-run organisation with no paid staff. It is funded by listener contributions and the occasional grant. The station is based in St Peters, South Australia.

The 1 October 1993 renaming — Three D Radio, from 5MMM — was the rebirth: the callsign sold, the new name, the 5DDD licence. The commercial Triple M — the 5KKA become 5MMM, the Hoyts network, the Austereo merger — is the namesake's other life: the community's letters, now the commercials' brand. The Adelaide Review's tribute — 'take care of your local air,' the community stations that 'weathered the blast' of the national signals — is the sector's story: the locals, thriving.
The show names — The Sound of Muesli, Shattered, Sunday Rise, 4 Course Breakfast, The Sunday Sleep In, Reverb, Something Over There, Revolution, Late For Breakfast, Roots & Branches, Strange Rampage, Jazz Voice — are the programming's personality: the wit, the eclecticism, the volunteers' imaginations. The decades — 1979 to today, 45-plus years — are the longevity: the seventies' idealism, still broadcasting. The alternative — the progressive, the local, the under-represented — endures: Three D, on 93.7.
The future — the 45-plus years, and counting — is the volunteers': the new announcers, the new shows, the quotas holding. The alternative endures: the progressive, the local, the under-represented, on 93.7 — Three D, the community's alternative.
