WSPR Globe

Getting Started

WSPR Globe visualizes WSPR (Weak Signal Propagation Reporter) spots on an interactive 3D globe. Each arc represents a radio propagation path between a transmitter and receiver.

Searching for Spots

• Call Signs: Enter a receiver or transmitter call sign to filter spots. Leave empty to see all spots.
• Time Window: Select how far back in time to search (from 5 minutes to 7 days).
• Frequency Bands: Check/uncheck bands to include or exclude specific frequencies.
• Load WSPR Spots: Click the button to fetch and display spots matching your criteria.

Display Modes

• Arc Mode: Shows propagation paths as arcs between TX and RX locations. Arcs peak at ~300 km altitude.
• Beacon Mode: Tracks a moving transmitter over time, showing its location at each 2-minute interval.
• Heatmap Mode: Color-codes regions by contact density (most active areas are brightest).

Visualization Options

• Animate Lines: Adds a moving "dot dot dot" pattern along arcs.
• Solid Lines: Makes arcs fully opaque (default is semi-transparent).
• Show TX/RX Markers: Displays solid circles at transmitters and open circles at receivers.
• Max Lines: Limits the number of arcs displayed for better performance.

Interacting with the Globe

• Rotate: Click and drag to rotate the globe.
• Zoom: Scroll to zoom in/out.
• Details: Click on any arc or point to see spot details (callsigns, distance, frequency, SNR, power, time).
