About
SDRmm is a software-defined radio application for listening, decoding, and recording signals. You can connect radios, channels, and displays in Patch view, then pin everyday controls to Rack view. It can run as a desktop app with a local SDR, or as a server placed near your antenna that you connect to through a browser. Both use the same receiver engine and interface.
It supports listening to AM, NFM, WFM with stereo and RDS, SSB, digital voice modes (DMR, P25, NXDN, D-STAR, FreeDV, M17), and noise reduction. Decoding covers aircraft, ships, pagers, amateur modes, weather satellites, radiosondes, DAB, DRM, and DVB. Displays include spectrum, waterfalls, maps, decoded messages, and video. Recording covers device IQ, channel baseband, audio, and each call, with pre-roll and SigMF playback.
SDRmm also offers scanning, signal identification, band monitoring, transmitter hunting, GPS and satellite tracking, and automation through REST, WebSocket, and MCP. It is licensed under the GNU Affero General Public License, version 3 or later.
