What grid square is the NE37 operating area?

NE37 is the live DXRadar reference square for the NE37 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of NE37 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 NE37 right now?

NE37 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 NE37 — the NE37 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from NE37 to each DX region at SFI 105 / 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 NE37

A planning heuristic for the local day at NE37, built from sunrise 00:03 UTC, sunset 12:09 UTC, SFI 105, and Kp 0.33. Not a measurement — a starting point for where to listen as the day turns.

Dawn grayline

Spots touching NE37 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in NE37, NE38, NE36, NE47, NE27. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate NE37 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.
