What grid square is the GR12 operating area?

GR12 is the live DXRadar reference square for the GR12 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of GR12 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 GR12 right now?

GR12 is currently rated FAIR. The best bands right now are 10m, 20m, 30m, 40m, 60m, with 10m as the main band to watch first.

Sunrise 09:18 UTC

Sunset 22:05 UTC from GR12

From the GR12 operating area, work the 09:18 UTC and 22:05 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses GR12.

Best band now

10m

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

● Best DX Windows from GR12 — the GR12 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from GR12 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 GR12

A planning heuristic for the local day at GR12, built from sunrise 09:18 UTC, sunset 22:05 UTC, SFI 118, and Kp 0.33. Not a measurement — a starting point for where to listen as the day turns.

Dawn grayline

around 09:18 UTC

40m · 30m · 20m

Grayline enhancement — low bands reach long distances as the terminator passes.

Morning

after 09:18 UTC

20m · 15m · 10m

High bands rising with the sun; check 10m for DX.

Midday

local noon

10m · 15m · 20m

Peak high-band window — 10m and 15m open widest.

Dusk grayline

20m · 40m

Second grayline peak — 20m holds, then hands off to 40m.

Night

after 22:05 UTC

40m · 80m

Low bands own the darkness — 40m for DX, 80m regional.

Spots touching GR12 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in GR12, GR13, GR11, GR22, GR02. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate GR12 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.
