Introduction

SDR++ is a highly acclaimed, open-source Software Defined Radio (SDR) application developed by AlexandreRouma. With over 5,500 stars on GitHub, it aims to provide a bloat-free and simple-to-use experience for SDR enthusiasts across Windows, Linux, MacOS, and BSD. The project is written in C++ and licensed under GPL-3.0, emphasizing its commitment to open development and community contributions.

Key features include:

  • Multi VFO (Virtual Front End)
  • Wide hardware support through SoapySDR and dedicated modules
  • SIMD accelerated DSP for efficient signal processing
  • Full waterfall update for easier and more pleasant signal browsing
  • Modular design, allowing users to easily write their own plugins

Installation

SDR++ offers various installation methods depending on your operating system. For the latest features and bug fixes, nightly builds are available.

  • Nightly Builds: Download the latest versions from the SDR++ website. Note that a GitHub account might be required to download artifacts.
  • Windows: Download the latest release from the Releases page and extract it.
  • Linux (Debian-based): Download the .deb package from the Releases page and install using sudo apt install path/to/the/sdrpp_debian_amd64.deb. Remember to install drivers for your specific SDR hardware.
  • MacOS: Download the app bundle from the latest nightly build. Building from source is also an option but is considered more complex.
  • BSD / Other Linux: Refer to the building from source instructions in the repository's README.

Examples

While SDR++ is primarily a software application, its modular design and configuration options provide flexibility for users. For instance, developers can easily build and integrate custom modules, as detailed in the "Building on Windows" and "Building on Linux / BSD" sections of the README.

Users can configure which modules are active by editing the config.json file, enabling or disabling various sources, sinks, and decoders. This allows for a tailored SDR experience, whether you're using an RTL-SDR, HackRF, or other supported hardware. The software's intuitive interface, as shown in the screenshot in the README, makes signal browsing and analysis straightforward.

Why Use SDR++

SDR++ stands out for several compelling reasons:

  • Cross-Platform Compatibility: It runs seamlessly on Windows, Linux, MacOS, and BSD, making it accessible to a broad audience.
  • Bloat-Free Philosophy: Designed with simplicity and efficiency in mind, it avoids unnecessary features, providing a lean and fast application.
  • Extensive Hardware Support: Compatibility with a wide range of SDR devices, both through dedicated modules and SoapySDR, ensures flexibility.
  • High Performance: SIMD accelerated DSP and full waterfall updates contribute to a smooth and responsive user experience.
  • Modular and Extensible: Its modular architecture encourages community contributions and allows users to customize their setup with plugins.
  • Active Community: With a presence on Discord and Reddit, users can find support and engage with other enthusiasts.
