    Digital Radio DAB+


    Digital Radio (DAB+) - What Is It?

    Digital radio, also known as DAB (Digital Audio Broadcasting), DAB+ (Digital Audio Broadcasting Plus) or Digital Radio, works by converting audio into digital signals for broadcast transmission. A DAB+ capable receiver decodes these signals to deliver clear, near-CD quality sound.

    The evolution of radio in Australia has progressed from AM to FM, and now to Digital Radio (DAB+).

    At present, DAB+ coverage in Australia is concentrated in major metropolitan areas and some key regional centres.

    Benefits of DAB+ Digital Radio:

    • More stations: Greater bandwidth means more channel choices, including digital-only stations.
    • Crystal-clear reception: No static, hiss, or interference like you get with AM/FM.
    • Superior sound quality: Near-CD audio quality for a premium listening experience.
    • Station information: Display of program details, song titles, and artist names where broadcast.
    • No ongoing costs: Free to air - no subscription or contracts required once you have a compatible receiver.
    • Easy station selection: Browse by station name rather than frequency.

    Which DAB+ features work in Australia?

    Most DAB+ data features are well supported here: nearly all Australian stations broadcast slideshow images, all provide dynamic scrolling text, and many include song and artist information, news and weather. An electronic program guide (EPG) is broadcast on at least one multiplex in each capital city.

    Some advanced features depend on the broadcaster, not the radio. Service Following (automatic switching between DAB+ and FM) only works where the station transmits the necessary linking information, so availability varies between networks. Check with the broadcaster if this matters to you.

    Please also note: DAB+ might not yet rebroadcast inside tunnels in Australia, unlike AM and FM, so expect brief drop-outs in tunnel sections.

    Things to Consider:

    • All-or-nothing reception: Unlike analog AM or  FM which tends to fade gradually, DAB+ either has perfect reception or drops out completely at range limits.
    • Coverage limitations: DAB+ is mainly available in metropolitan areas; rural and remote locations may have limited or no coverage.
    • Data services depend on broadcasters: Song and artist information requires stations to transmit additional service data - not all stations provide this.
    • DAB Aerial: DAB+ doesn't directly work off AM and FM aerials. Either a dedicated DAB+ aerial is needed, or a splitter unit which can then obtain a DAB+ signal from the existing AM/FM aerial. We can supply both these items if needed.
