What grid square is Japan operating area?

PM69 is the live DXRadar reference square for Japan operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of PM69 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.

What bands are open in PM69 right now?

PM69 is currently rated POOR. The best bands right now are 10m, 20m, 30m, 40m, 60m, with 10m as the main band to watch first.

● Best DX Windows from PM69 — Japan operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from PM69 to each DX region at SFI 105 / Kp 2, 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 PM69 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in PM69, PN60, PM68, PM79, PM59. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate PM69 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.
