What grid square is the JR93 operating area?

JR93 is the live DXRadar reference square for the JR93 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of JR93 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 JR93 right now?

JR93 is currently rated FAIR. The best bands right now are 10m, 20m, 30m, 40m, 60m, with 10m as the main band to watch first.

From the JR93 operating area, work the 03:54 UTC and 17:21 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses JR93.

Best band now

10m

Night operation should keep 20m on watch and move to 40m as the path darkens.

● Best DX Windows from JR93 — the JR93 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from JR93 to each DX region at SFI 115 / Kp 0.67, 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 JR93 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in JR93, JR94, JR92, KR03, JR83. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate JR93 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.
