Installation guides
1

Turn your Raspberry Pi into a real AM / FM / DAB / DAB+ / HD Radio receiver

A complete Raspberry Pi radio shield with local Web UI, CLI control, built-in 1 x 5 W amplifier, headphone output, analog audio output, and I2S digital audio for recording or processing.

Listen to real broadcast radio locally — no internet required for reception.

Why this product matters

The Raspiaudio Digital Radio Shield brings real broadcast radio reception directly to Raspberry Pi boards with a standard 40-pin header. It supports AM, FM, DAB, DAB+, and HD Radio, and can be controlled from a local web interface, from the command line, or directly from the onboard navigation button.

It is designed for both product integration and prototyping: standalone radio devices, embedded audio systems, custom radio software, kiosks, museums, and local radio applications that do not depend on cloud services.

What you can do

  • Receive AM, FM, DAB, DAB+, and HD Radio
  • Control the radio from any browser on your local network
  • Use the CLI for automation or software integration
  • Output audio through headphone jack, analog output, or external passive speaker
  • Use the built-in 1 x 5 W amplifier for standalone projects
  • Record or process digital audio through I2S
  • Build menu-based standalone interfaces with the onboard navigation control

This looks interestIng.

When receiving DAB or DAB+ is the whole multiplex available to software so that, for example, multiple stations can be played at the same time by different remotely connected sessions?

4

Hi Paul, no this is one tuner only so only one station can be played at the time.

5

FYI I have an old DAB USB device and it only has one “tuner” but it tunes to the DAB multiplex and then all

Of the stations of that multiplex become available at the same time.

Similar things are possible in the DVB-T world.

6

You are correct: with one tuner locked to a DAB multiplex, all services from that multiplex are present in the stream, so in theory software could decode several of them.

In this case, though, this product is intentionally designed as a straightforward radio receiver, not as an SDR tool or a multi-user streaming platform. The goal is immediate listening pleasure on a proper Hi-Fi setup, with good sound quality and a built-in amplifier.

So the device is meant to play one station at a time.

Understood - still looks good.

Does the FM-style telescopic antenna work well with DAB?

8

Yes, it is working well i get more than 60 dab station where I am in Paris Area, for optimal reception I deploy the antenna to 75% of its lenght.
