Creating this thread to post news about the OpenWebRX+ project and answer questions.
OpenWebRX+ is Linux-based project that lets you share your RTLSDR or a bunch of other SDR receivers online. It contains decoders for many communication modes, including HAM, aviation, and maritime communications. OpenWebRX+ can decode received data either interactively, or in background, sharing results via MQTT. It has a built-in map and a file browser for accessing decoded SSTV, weather fax, and other files.
For details, please, take a look at OpenWebRX+ documentation. You may also want to visit the news channel on Telegram.
