Versions:
SDRangel 7.24.0, released by developer f4exb, is a multi-platform software-defined radio (SDR) transceiver application engineered to operate an extensive roster of popular low-cost and professional radios. Built for reception and transmission tasks, the program natively supports Airspy, Airspy HF+, BladeRF, HackRF, LimeSDR, PlutoSDR, RTL-SDR, SDRplay RSP1 and FunCube dongles, turning them into real-time spectrum analyzers, channel monitors, digital voice gateways or modulated signal generators. Typical use cases span amateur radio experimentation, satellite telemetry decoding, wide-band spectrum surveillance, EMC pre-compliance testing, GNSS signal monitoring, remote RF sensor networks, and educational RF laboratories where students visualize modulation schemes in live waterfalls. A modular plugin architecture allows operators to chain DSP blocks such as FM, AM, SSB, CW, DMR, D-Star, C4FM, LoRa, ADS-B or custom OFDM transceivers, while rig-control integration provides CAT-like frequency tracking for transverter-driven microwave setups. Since its debut the project has evolved through twenty-six public versions, progressively adding MIMO support, remote headless server mode, high-resolution GPU-accelerated displays, macro scripting, and sample rates beyond 20 Msps for oversampled wide-band recording. Cross-platform builds for Windows, Linux and macOS share a unified GUI that can be detached into separate dock widgets, enabling multi-monitor spectrum displays common in signal-intelligence workstations. Users can store complete station profiles—hardware settings, channel presets, visual layouts—for rapid switching between HF utility hunting, VHF air-band scanning, or 2.4 GHz Wi-Fi band characterization. SDRangel is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
