Despite the best efforts of records, videos, cassettes, CDs and music streaming, radio has survived every single format that was "destined to kill broadcasting". In fact, digital broadcasting is still going strong, and there are plenty of home radios to choose from. These range from basic portable models all the way up to high-end hi-fi units for serious audio enthusiasts.
Digital radio claims to offer a handful of improvements over standard analogue broadcasts. Improved audio quality is the big hook, but digital radio can also transmit information like the artist name and song title, album art and even the weather. Australia uses an upgraded version of the global Digital Audio Broadcasting standard called DAB+.
This is similar to music streaming services like Spotify or Apple Music. But unlike streaming, digital radio broadcasts its data package instead of sending it over a network which means you don't need to worry about data usage at home or on the go.
Most major stations simultaneously broadcast (aka simulcast) in digital which means you can pick up Triple M or WSFM, for example, on your digital radio and FM tuner. But there are a number of stations available exclusively in digital as well. These are usually offshoots from big broadcasters with more of a specific genre focus such as ABC Jazz, Nova 90s and SBS Pop Asia. Check out the full list of digital stations.
Digital radio also hosts pop-up stations. These are temporary channels which coincide with a special event or time of year, such as the annual Christmas carols station, Elf Radio or a band touring throughout the country with pop-up stations in each city. Then, there are the random ones like Coles Radio – yes, that's the same music you hear in the supermarket.
What about community radio?
Digital radio is less common amongst local and community broadcasters. Check the station's website or social media pages before buying to make sure your favourite station is available.
Before buying, you need to make sure that digital radio is available in your area. Though it's rolled out in all capital cities, coverage is less consistent in regional areas. Head to the Digital Radio Plus website and enter your postcode to see if you can access it. The site also provides maps of city regions showing the areas of good reception as well as marginal areas.
Some rugged radios are designed for use outdoors and in dirty environments, like a shed or garage.
Digital radios come in all shapes and sizes, just like analogue models. You can still get portable and desktop models, and some hi-fi systems have them built in as well. Portable and desktop models can look like old-style traditional radios and the retro 1950s look seems to be in vogue. Contemporary styles are also available though, if you're feeling less nostalgic.
How to get digital radio in a car
Most manufacturers are including them as standard in most car models. However, they also offer FM which you will no doubt need if you're driving in regional areas. If you want to add one to your existing vehicle, you can get one fitted by a specialist as this will usually require installation of a specific aerial that can receive digital broadcasts.
Can I stream digital radio online?
You can't stream digital radio online as it's broadcast over radio waves rather than the internet, but most stations simulcast online via their websites or apps, so you can stream them to your smartphone, tablet or computer. This is a handy workaround if don't have a digital radio, particularly in a car with Bluetooth, though streaming will use your data.
Most digital radios, or cars and hi-fi systems with a digital tuner, can pick up FM broadcasts, but you won't find many with an AM receiver. This isn't a huge problem if you listen to one of the major AM stations as they usually simulcast in digital, but smaller broadcasters may not.
Some digital radios have Wi-Fi and/or ethernet connectivity, giving you the option to stream audio from internet radio stations, a local server (via DLNA) and music streaming services like Spotify. Check the specs to see which streaming options are available, as networking doesn't necessarily mean that it will support all online content by default.
If the radio has built-in support for music streaming services, then it should support the "connect" feature. This lets you connect your device to the radio to use as a remote, while the radio streams the music which is better quality than Bluetooth.
Alternatively, most digital radios support Bluetooth and some even have an auxiliary (AUX) input, even if they don't allow networking. In either case, you can connect your device to stream the audio, while the digital radio basically becomes a speaker.
These are some other things to look for when researching digital radios.
- AirPlay: Easy connectivity for Apple devices, with unique functions.
- Alarm: Useful for waking up in the morning, but can also be used to remind you that a program you want to tune into is about to start. DAB+ clock radios are more accurate than normal clock radios and automatically adjust for daylight saving changes.
- AUX input: Handy if you want to connect other devices without dealing with Bluetooth.
- Casting: Easy connectivity for Android devices, with unique functions
- DAB+: Digital radios that use standard DAB won't work in Australia. Make sure it supports DAB+, especially if you're importing one from overseas.
- Headphone socket
- Line out: You'll need this if you want to connect your radio to external speakers or a more powerful sound system, via an amplifier or receiver.
- Remote control
- Screen size and shape: Look for screens that are big enough to read, and ones that let you scroll down, because it's easier than scrolling across.
- Speaker type: Many self-contained models have a mono speaker. Don't assume they're all stereo.
- USB: Can be used to play digital music files (e.g. FLAC), but it's often just an input for firmware updates.
In our latest reviews, portable digital radios ranged in cost from about $100–450, and desktop digital radios ranged from $250–1000.
