Best report and furthest distance in each direction. These only know about contacts reported through the service — a purely RF contact that never touched the internet is invisible here.

Where this comes from
Callsigns and Maidenhead locators are the same details every operator already transmits on the air. Nothing here is finer than a grid square, and only operators who opted in to publishing appear at all. Figures are built from what the Open Signal service has recorded since 31 July 2026 — so treat them as a floor, not a complete log of this station’s activity.
