Send WSJT-X data to multiple applications
WSJT-X can send data to only one downstream application. WSJT-X Relay bridges that gap by relaying data between WSJT-X and multiple downstream applications. It supports bi-directional traffic flows, is easy to set up, and works with WSJT-X-aware tools on your LAN or across WAN links. Built and maintained by W1BBT.
End-User Features
- One-to-many UDP forwarding from one WSJT-X listen port to multiple downstream apps
- Bi-directional relay behavior so downstream reply traffic is sent back to WSJT-X
- Simple start/stop control with clear running/stopped status
- Live status indicators for frequency, mode, TX state, listen port, and targets
- Real-time activity log for relay traffic and events
- Persistent settings and QSO data between sessions
- Manual QSO entry for non-digital contacts (for example SSB/CW)
- Built-in QSO log view with running counts and recent activity
- QSO Editor window for reviewing and editing saved contacts
- ADIF import/export support
- Resend one or all saved QSOs to forward targets
- Light and dark themes

Club/Group Server Monitoring
With WSJT-X Relay, aggregating your club or group logs in one place is as simple as adding the server as a forward destination. Below is the personal group server my beta testers and I use:
