OpenRSP’s open driver stack for RSP receivers
OpenRSP is an open-source replacement driver stack for RSP-family software-defined radio receivers, with an API intended to match SDRplay API 3.15.
- For
- RSP receiver owners and SDR application developers
- Worth noticing
- The project's Linux measurements report 18% less CPU at 2 MS/s and 34% less at 10 MS/s, using the same receiver and settings.
Field notes
The implementation is described as three layers: an API library, a USB-owning background service, and receiver bridge firmware. Its published compatibility target is SDRplay API 3.15, with Linux packages plus Android and Apple-silicon iPadOS support; the homepage also links to a browser interface for spectrum, waterfall, audio, radio, and vessel or aircraft tracking. The performance figures are project-reported measurements on Linux with real hardware, not independently verified results.
