What grid square is the AO27 operating area?

AO27 is the live DXRadar reference square for the AO27 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of AO27 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 AO27 right now?

AO27 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 17:26 UTC

Sunset 05:41 UTC from AO27

From the AO27 operating area, work the 17:26 UTC and 05:41 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses AO27.

Best band now

10m

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

● Best DX Windows from AO27 — the AO27 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from AO27 to each DX region at SFI 104 / Kp 0, 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 AO27

A planning heuristic for the local day at AO27, built from sunrise 17:26 UTC, sunset 05:41 UTC, SFI 104, and Kp 0. Not a measurement — a starting point for where to listen as the day turns.

Dawn grayline

40m · 30m · 20m

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

Modest SFI — 20m is the daytime workhorse here.

Midday

Spots touching AO27 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in AO27, AO28, AO26, AO37, AO17. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate AO27 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.
