on GitHub

What's New in v2.22.0

Added

• Waterfall Receiver Overhaul — WebSocket-based I/Q streaming with server-side FFT, click-to-tune, zoom controls, and auto-scaling quantization
• Voice Alerts — Configurable text-to-speech event notifications across modes
• Signal Fingerprinting — RF device identification and pattern analysis mode
• SignalID — Automatic signal classification via SigIDWiki API integration
• PWA Support — Installable web app with service worker caching and manifest
• Real-time Signal Scope — Live signal visualization for pager, sensor, and SSTV modes
• ADS-B MSG2 Surface Parsing — Ground vehicle movement tracking from MSG2 frames
• Cheat Sheets — Quick-reference overlays for keyboard shortcuts and mode controls
• App icon (SVG) for PWA and browser tab

Changed

• WebSDR overhaul — Improved receiver management, audio streaming, and UI
• Mode stop responsiveness — Faster timeout handling and improved WiFi/Bluetooth scanner shutdown
• Mode transitions — Smoother navigation with performance instrumentation
• BT Locate — Refactored JS engine with improved trail management and signal smoothing
• Listening Post — Refactored with cross-module frequency routing
• SSTV decoder — State machine improvements and partial image streaming
• Analytics mode removed; per-mode analytics panels integrated into existing dashboards

Fixed

• ADS-B SSE multi-client fanout stability and update flush timing
• WiFi scanner robustness and monitor mode teardown reliability
• Agent client reliability improvements for remote sensor nodes
• SSTV VIS detector state reporting in signal monitor diagnostics

Documentation

• Complete documentation audit across README, FEATURES, USAGE, help modal, and GitHub Pages
• Fixed license badge (MIT → Apache 2.0) to match actual LICENSE file
• Fixed tool name rtl_amr → rtlamr throughout all docs
• Fixed incorrect entry point examples (python app.py → sudo -E venv/bin/python intercept.py)
• Removed duplicate AIS Vessel Tracking section from FEATURES.md
• Updated SSTV requirements: pure Python decoder, no external slowrx needed
• Added ACARS and VDL2 mode descriptions to in-app help modal
• GitHub Pages site: corrected Docker command, license, and tool name references
