When DAB radio was first launched, it promised to put an end to the problem of poor AM and FM signals. So why is it that so many DAB users find themselves having this very same issue? If you’re finding yourself frustrated by bad DAB signal, then don’t worry- we’re here to help. Read on, and we’ll talk you through some of the most common causes of this irritating issue, and explain the best fixes for each one.

How Can I Tell If I’ve Got Poor DAB Signal?
A lot of users don’t even realise that their DAB radio problems are down to a poor signal. Instead, they assume that something is wrong with the device itself. That’s because they are so used to that trademark hiss and crackle of FM radio interference. However, DAB radio works in a whole different way to FM. That means a weak signal will manifest itself in other ways. Often, it sounds almost as if the broadcast is coming from underwater, or the sound will just drop out altogether.
Are You In A DAB Blackspot?
First things first, that poor DAB reception might be down to where you live. Just like regular FM radio, DAB signals are sent out by transmitters located across the UK. If you live near one of these, then you shouldn’t have too much of a problem with your DAB signal. However, there are a few places in the country that are out of the range of these transmitters. The Scottish Highlands and Islands, as well as the Pennines and mid-Wales, are effectively blackspots when it comes to radio signal of any kind.
If you live in one of these areas, though, you shouldn’t just give up on digital radio. If you’ve got a relatively strong broadband connection, then there’s actually a very easy way around this issue. Most digital radio stations- and tens of thousands more- are available to stream online. Some digital radios can tune straight into these through WiFi. Most other mid- to high-range DAB radios support Bluetooth connectivity, so you can just link up your phone or tablet and you’ll be ready to go. This also lets you play music through your radio from your favourite streaming platforms- perfect!
Try Repositioning Your DAB Radio
Even if you live somewhere with supposedly strong DAB signal, you might still have some trouble with picking up your favourite stations. In these cases, it’s most likely down to where you position the DAB radio in your home. It’s harder for radio signals to penetrate through thick concrete walls. This is especially true in cellars and rooms right in the centre of larger buildings. Every time the transmission has to pass through a solid object, it gets weaker and weaker- until your radio simply can’t tune in.
In rooms with poor signal, you should try to place the radio as close to a window as possible. Some DAB radios display the current signal strength on their screen, so keep checking this and moving the radio around until you find that sweet spot. If this isn’t an option in your chosen room, or if you’ve tried this and it hasn’t helped, then the next step is moving the aerial about. Just like an FM radio, DAB aerials can be a bit tricky to get in the right position sometimes. It’s worth trying out a range of lengths and angles. As a rule of thumb, though, DAB aerials tend to work best when vertical and extended at least 35 cm.
Other Devices Sometimes Cause Interference
It’s not just thick walls that can block digital radio signals. Depending on where you’ve placed the unit, there might be other electrical devices causing some interference. This is especially common with LCD TVs, but other common culprits include laptops, mobile phones, and touch lamps. Finding the source of the interference is a matter of switching nearby devices off one at a time, and checking the radio signal each time. When it starts to improve, you’ve found the main offender!
Interference is far more likely if you live somewhere with poor DAB signal to begin with. Since the radio will already struggle to pick up transmissions, even small amounts of interference can cause big problems. In these instances, we recommend that you try to keep your radio and TV setups at opposite ends of the room, so that one doesn’t jam the other.
Retune Your DAB Radio
If all else fails, you might want to try retuning your DAB radio. It might be the case that the station you’re trying to tune into has switched frequencies. With new digital radio stations cropping up all the time, you’ll want to retune the radio frequently anyway. That way, you’ll always be on top of the latest offerings in your area. Most DAB radios have a retune button, but if not, you’ll find this option somewhere in the main menu.
