What grid square is Sapporo?

QN11 is the live DXRadar reference square for Sapporo. The exact portable or home QTH may vary within the square, but this page tracks the center of QN11 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 QN11 — Sapporo

Great-circle distance, short-path beam heading, the bands most likely open right now from QN11 to each DX region at SFI 105 / Kp 1.33, 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.

Recent local activity

Spots touching QN11 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in QN11, QN12, QN10, QN21, QN01. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate QN11 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.
