Choose one data source below, then use the shared matrix controls to compare activity received by one reporter from two independently selected destination areas.
1. Receiver callsign and date2. Configure destination areas3. Collect or import data4. Build, review, save, and export
3. WSPRnet Data Collection (alternative source)
Use WSPRnet to create and save source files. For busy bands, collect individual band files to avoid the 10,000-row download limit.
Select one or more saved WSPRnet result files. Exact duplicate rows are removed automatically.
3. wspr.live Data Collection
Manual requests use the latest completed 30-minute UTC bin with a shared 5-second cooldown. Automatic day collection is user-started: it acquires the nine bands every three minutes for the preceding completed bin, retains consecutive bins, and stops after the UTC day. Trial fairness mode staggers each browser's automatic requests.

1. Receiver Callsign and Date
Enter the receiver callsign before using wspr.live. WSPRnet files identify their reporter automatically when imported.
2. Configure Destination Areas
Path 1 Destination
Path 2 Destination
4. Build Matrix from WSPRnet Data
Build from imported WSPRnet data here. Build from wspr.live data in the green collection panel, then use the shared review and export controls below.
Data and Matrix Status No data selected
No collection started. This feature makes no requests until a band button is pressed.
Import saved WSPRnet data or collect wspr.live data, then build the matrix.

All Beacons Heard by Reporter
This separate matrix shows every beacon heard by the exact reporter callsign in the imported or collected data. It is not filtered by either selected destination area.
At WSPRnet, leave Unique unchecked. Raw Spots counts every imported report row. Unique Beacons Per Bin counts each beacon callsign once within each 30-minute, band, and destination cell. Cumulative Unique Beacons counts each beacon callsign once across the UTC day and shows the running total by time bin. Exact duplicate imported rows are removed in all modes to prevent overlapping downloaded files from double-counting the same report. Destination filtering uses each beacon Grid and the selected city radius. SNR is not used.
