## Tips

1. **Use Your Callsign** - Some clusters require valid callsigns
2. **Check Multiple Clusters** - Coverage varies by region
3. **Filter by Band** - Focus on bands you can work
4. **Track Rare Prefixes** - Set up alerts for most-wanted
5. **Morning Check** - Best DX often in early morning

## Technical Details

- **Protocol:** Telnet to DX cluster nodes
- **Format:** Standard PacketCluster/AR-Cluster format
- **State Tracking:** `/tmp/dx-monitor-state.json`
- **Dependencies:** Python 3.6+ (stdlib only)

## Future Ideas

- Band-specific filtering
- DXCC entity tracking
- Propagation prediction integration
- Log integration (check if you need that one)
- Contest mode (filter contest stations)
- FT8/FT4 integration via PSKReporter

73 and good DX! 📻🌍
