HF Propagation Map - Help
Summary: Aggregated signal strength and activity per 4-character grid.
Cluster: Directional activity from a specific grid.
MUF (Beta): Estimated Maximum Usable Frequency per grid.
Reports: Historical data per callsign or grid, including direction (sent/received), plus true two-way QSOs (only contacts where both sides saw each other) from the last 10 minutes.
Realtime: Live MQTT feed from PSK Reporter showing spots as they happen in real-time. Shows activity from the last 10 seconds (no filter) or last 1 minute (callsign/grid filter). Auto-pauses when tab is hidden to save bandwidth.
POTA: Parks on the Air activation paths and global view.
QSO: Upload and visualize your own ADIF log on the map. Shows your contacts with paths, band/mode filters, and options to toggle arcs and time labels.
How to use:
- Select a view: Summary, Cluster, MUF, Reports, Realtime, POTA, or QSO.
- Use filters (Band, Mode, Grid, etc.) to refine results.
- Click "Go" to load filtered data for views like Cluster or Reports.
