What grid square is the ON16 operating area?

ON16 is the live DXRadar reference square for the ON16 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of ON16 for planning propagation.

How do I find my grid square?

Use a Maidenhead grid lookup from your GPS coordinates or street address, then compare that grid with the nearby squares linked on this page. A 4-character grid is enough for most HF planning.

● Best DX Windows from ON16 — the ON16 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from ON16 to each DX region at SFI 105 / Kp 0.33, and a current verdict. "Open now" means a suitable band is scoring well on that path; "Try ~HH:MM" points at the next far-end grayline. Band picks and status are a planning heuristic, not a measurement.

Spots touching ON16 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in ON16, ON17, ON15, ON26, ON06. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate ON16 footprint right now. That usually means you should widen the search to the nearest regional hubs below or fall back to 20m/40m for the next operating window.
