Technology has greatly changed the way we consume media. One notable advancement in radio technology is Digital Audio Broadcasting (DAB), which offers a broader range of stations and better sound quality. However, not all countries have adopted this new technology. So, out of curiosity, does the USA have DAB radio?
USA radio broadcasters have DAB radio that broadcasts using in-band on-channel technology. The technology means these radios broadcast analog (FM/AM) and digital signals simultaneously. This is why DAB has limited availability and adoption in the USA.
In the rest of this article, I’ll discuss the use of DAB radios in the USA. I’ll also talk about the differences between DAB and other radios, including how to use them in the US.
Let’s get started!
Can You Use Your Digital Radio in the USA?
You can use your digital radio in the US if it has in-band on-channel technology. However, according to the US Federal Communications Commission (FCC), only in-band on-channel technology (IBOC) is approved for AM (daytime and nighttime) and FM broadcasting.
Here’s a simple way to think about IBOC technology: a station that uses 102.7 FM will have a similar frequency on the digital radio.
What does this mean if you want to travel to the US from a country like the UK?
An important point is that conventional DAB radios used in countries like the UK, Africa, Australia, and Asia may not work in the US.
Since the USA allows only the IBOC signal propagation, you need a compatible radio to receive these signals.
In a nutshell, you’ll need to buy an IBOC-compatible digital radio for use in America.
The Workings of Digital Radios
Digital radios are more efficient than their traditional analog counterparts because they are not susceptible to interference from neighboring channels.
Therefore, they receive more channels than their FM and AM counterparts. How do they work?
These radios convert and transmit sound in the form of digital signals. The broadcasting station generates and encodes audio into digital signals before transmitting them to the digital radio receiver.
The receiver decrypts the digital signals, converting them into audio. The decryption process creates superior sound quality because of the digital signal processing that eliminates noise.

The Difference Between DAB and Other Radios
How do DAB radios differ from Internet and satellite-based radios? Here are the key differences.
● Broadcasting technology in the US: While the DAB radios use IBOC technology in the US, their Internet and satellite counterparts are broadcast as individual channels.
● Energy consumption: DAB radios use less energy than Internet or satellite radios because they receive the signal directly from the broadcasting station. The signals don’t go through an intermediary (such as a satellite).
● Band range: DAB radios have greater ranges due to their broader bands. The greater range allows you to listen to more radio stations.
● Frequency range: DAB radios use higher frequencies in the electromagnetic spectrum than analog FM/AM radios. The higher the signal frequency, the better the sound quality and reception. Moreover, higher frequencies are less prone to interference from other channels.
● Listening experience: FM and AM radios are prone to static sounds and other disruptions, mainly due to weak signals. Digital radios, however, provide a smooth and uninterrupted listening experience.
● Channel options: DAB radios use DAB-multiplexing technology to display multiple digital radio channels on the same frequency. This allows you to choose from a wide range of audio programs.
How to Use DAB Radio in the USA
At this point, you know the US restrictions for using DAB radios. Now, how can you make the best of them?
First, you can buy an IBOC-based radio or a compatible digital adaptor. Various models have different features depending on your budget and requirements.
Alternatively, you can listen to satellite and online radios if you can access the Internet.
Finally, you can receive stations from other countries while in the US. For instance, you can receive UK-based programs in the US through the BBC World Service.
You can also listen to these stations online using a standalone Internet radio receiver, online streaming on sites like TuneIn, or a smartphone app.
The US does have DAB radio, but only if your digital receiver has IBOC technology.
This technology allows broadcasting stations to transmit analog and digital signals simultaneously at the same frequency.
With digital radios, you get better sound quality and receive a broader range of programs than traditional analog FM or AM stations.
Furthermore, a digital radio receiver will let you receive high-quality international radio programs free of scratches.
It’s possible to get some interference on your DAB radio. Luckily, there are ways to stop such interference for uninterrupted sound and clarity.
