DXLook Events - Help

Events View: Plan your ham radio contest or field day operations using VOACAP propagation predictions.

How to use:

• Select an event from the dropdown to see the event dates
• Use the Hour slider to see predictions for different times of day
• For multi-day events, select the specific day in the Configuration panel
• Enter your grid square and click "Go" to see predictions from your location
• Filter by band to focus on specific frequency ranges
• Use the SSN selector to compare different solar activity scenarios

Arcs: Colored arcs show predicted propagation paths. Arc color indicates the optimal band, thickness indicates signal quality.

SSN (Sunspot Number): Affects HF propagation - higher SSN means better conditions on higher bands (10m, 15m, 20m). The SSN selector shows NOAA's predicted values with confidence intervals:

• Predicted - Central forecast (most likely)
• High 75%/25% - Upper confidence bounds
• Low 25%/75% - Lower confidence bounds
