🔧 How to Use

• Data is retrieved from the official WSPRNet database: wsprnet.org/olddb
• Enter a full and exact callsign (wildcards like * or % are not supported — e.g. SP3R* won’t work).
• Leave the callsign field empty to display all transmitting stations within the selected time window
• Select a band and how far back in time you want to search.
• Click 🔍 SEARCH to view recent WSPR activity.

🗺 Map View

• Red dots = Transmitting (TX) stations — either the callsign you searched for, or all stations if the field was left empty
• Green dots = Receiving (RX) stations that reported the TX station
• Curved lines represent each WSPR link between TX and RX
• Click any callsign on the map to open its QRZ.com page

🌒 Day/Night Terminator
