What grid square is Sendai?

QM08 is the live DXRadar reference square for Sendai. The exact portable or home QTH may vary within the square, but this page tracks the center of QM08 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 QM08 — Sendai

Great-circle distance, short-path beam heading, the bands most likely open right now from QM08 to each DX region at SFI 104 / Kp 0, 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 QM08 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in QM08, QM09, QM07, QM18, PM98. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate QM08 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.
