TX = reports sent from the grid and heard elsewhere. RX = reports heard by stations in the grid.

Notes

• The summary currently uses PSKReporter only.
• The request does not filter by mode, so it includes all PSKReporter-reported modes.
• TX Reports counts reports sent from the grid and heard elsewhere.
• RX Reports counts reports heard by stations in the grid.
• RX counts come from raw receptionReport rows.
• TX counts combine raw sender-side reports with PSKReporter sender-side summary counts when raw rows are not available for a mode.
• DXCC columns count distinct PSKReporter DXCC values seen on each band.
• Max distance columns are computed from raw locator pairs and shown in miles.
• RX Furthest DXCC shows the DXCC country on the furthest raw RX path for that band.
• Unknown or unsupported frequencies are ignored.
