GridTracker is an amateur radio companion that turns activity from applications such as WSJT-X into a visual operating environment. Its centrepiece is an interactive map showing live and historical radio activity, Maidenhead grid squares and information useful when deciding which stations to work.
It has grown well beyond its original role of plotting WSJT-X traffic. GridTracker combines decoded activity, logbook information, spotting, award progress, callsign data and propagation-related information, making it particularly useful to operators working FT8 and other digital modes.
This is free and open source software.
Key Features
- Display live digital-mode activity on an interactive world map.
- Read WSJT-X and compatible activity and associate decoded stations with geographic locations.
- Load existing ADIF logs so previous contacts contribute to map and award information.
- Display Maidenhead grids and identify worked and unworked geographic areas.
- Use a configurable Call Roster to examine live activity without relying entirely on the map.
- Initiate appropriate contacts directly from displayed activity when used with supported digital-mode software.
- Configure audio and visual alerts for stations or operating conditions of interest.
- Perform callsign lookups through supported amateur radio databases.
- Track DXCC, countries, prefixes and other award-related information.
- Integrate with external logging applications and online logbook services.
- Display real-time spot information alongside decoded radio traffic.
- Provide solar, weather and other information relevant to radio propagation.
- Operate without Internet access for field, POTA, SOTA, IOTA and mobile workflows.
- Cross-platform support – run on Linux and other desktop platforms using NW.js.
