Raw Spots counts every collected report row. Unique Beacons Per Bin counts each beacon callsign once within each 30-minute band/destination cell. Cumulative Unique Beacons counts each beacon callsign once across the UTC day and shows the running total by time bin. For the global matrix, destination filtering does not apply. For each selected path matrix, destination filtering uses either the selected city radius or the selected map grids. SNR is deliberately not used for this wspr-matrix App.
