About SDRconnect
SDRconnect is the current official software for SDRplay's RSP software-defined radio receivers, replacing the older Windows-only SDRuno. It runs on Windows, macOS (Intel and Apple Silicon) and Linux and gives a spectrum and waterfall display, standard demodulation modes and receiver controls tuned to RSP hardware. A headless server mode lets a receiver sit near a good antenna while you listen from another machine. That fits SDRplay's networked nRSP-ST. A built-in WebSocket API lets other programs and scripts control the radio. It's a free download for owners of SDRplay hardware and supports every RSP model except the original RSP1. It needs a 64-bit system, and on Linux only Ubuntu LTS releases are tested. Because it's made for one brand of hardware, owners of RTL-SDR, Airspy or HackRF devices should look at general-purpose programs instead.
Best for: SDRplay RSP owners who want the vendor's maintained, cross-platform receiver app.
