Before installing this plugin, make sure that your version of SDR++ is the same as the one in vendor/sdrplusplus. If it isn't refer to the build instructions to compile for your version of SDR++.

Core algorithms for DAB radio are used from https://github.com/williamyang98/DAB-Radio.

SDR++ is at https://github.com/AlexandreRouma/SDRPlusPlus/tree/master/core.

Download instructions

Download from releases page or build using the instructions below. Make sure you download the correct version if available.

Usage instructions

Windows

1. Paste dab_plugin.dll into modules/ folder inside your SDR++ install.
2. Open SDR++.
3. Inside Module Manager tab on the left panel add dab_decoder as a plugin.
4. Browse to a valid DAB frequency using the following link: https://www.wohnort.org/dab/.
5. Check the OFDM/State tab to see if the OFDM demodulator is active.
6. Select the DAB/Channels tab and select one of the DAB+ channels.
7. If no sound is present, check the Sinks tab and make sure that DAB Radio is set to Audio and to the correct audio device.
8. You may also copy fftw3f.dll into the main SDR++ folder since it is compiled with AVX2 which may improve performance. Be sure to backup the original file before replacing it.

Refer to the build instructions if your processor doesn't support AVX2 instructions to compile with SSE2 or AVX instructions.

Build instructions

Refer to toolchains/*/README.md for build instructions. The github workflows in .github/workflows can also be used as a reference for a working build setup.

TODO

• Improve the user interface so that you can view as much information as the original GUI found here.
• Improve integration with SDR++.
• Determine how to make this build crossplatform with all the necessary dependencies.
