Read Me

WSPR Matrix is a browser app for reviewing observed WSPR activity from a selected reporter across a UTC day.

Purpose

The app helps radio operators and propagation researchers see daily activity patterns by band, 30-minute UTC time slot, and selected destination area.

What The App Does

• Collects live ClickHouse data or loads JSON Data, then builds a 30-minute UTC/local-time table showing observed activity by band.
• Builds a two-path matrix using selected destination areas and endpoint radii.
• Builds an all-destinations Global matrix for the same reporter and date.
• Supports raw spots, unique beacons per bin, and cumulative unique beacons.
• Exports CSV, saves/loads collected JSON data, and supports browser print/PDF.
• View more than two destination paths and more than one spotter callsign by placing two browser windows side-by-side.

Scientific Boundary

The matrix shows observed activity. It does not, by itself, prove short-path or long-path propagation. Directional path claims need separate evidence.
