What grid square is the OA47 operating area?

OA47 is the live DXRadar reference square for the OA47 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of OA47 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 OA47 right now?

OA47 is currently rated FAIR. The best bands right now are 10m, 20m, 30m, 40m, 60m, with 10m as the main band to watch first.

● Best DX Windows from OA47 — the OA47 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from OA47 to each DX region at SFI 118 / 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.

● Band-by-Time Plan for OA47

A planning heuristic for the local day at OA47, built from sunrise 22:15 UTC, sunset 11:00 UTC, SFI 118, and Kp 0.33. Not a measurement — a starting point for where to listen as the day turns.

Spots touching OA47 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in OA47, OA48, OA46, OA57, OA37. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate OA47 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.
