What grid square is the DB21 operating area?

DB21 is the live DXRadar reference square for the DB21 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of DB21 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 DB21 right now?

DB21 is currently rated POOR. The best bands right now are 20m, 30m, 40m, 60m, 10m, with 20m as the main band to watch first.

Sunrise 13:14 UTC

Sunset 01:53 UTC from DB21

From the DB21 operating area, work the 13:14 UTC and 01:53 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses DB21.

Best band now

20m

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

● Best DX Windows from DB21 — the DB21 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from DB21 to each DX region at SFI 121 / Kp 3, 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 DB21

A planning heuristic for the local day at DB21, built from sunrise 13:14 UTC, sunset 01:53 UTC, SFI 121, and Kp 3. Not a measurement — a starting point for where to listen as the day turns.

Dawn grayline

around 13:14 UTC

40m · 30m · 20m

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

Spots touching DB21 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in DB21, DB22, DB20, DB31, DB11. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate DB21 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.
