What grid square is the IR21 operating area?

IR21 is the live DXRadar reference square for the IR21 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of IR21 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 IR21 right now?

IR21 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 06:21 UTC

Sunset 19:26 UTC from IR21

From the IR21 operating area, work the 06:21 UTC and 19:26 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses IR21.

Best band now

10m

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

● Best DX Windows from IR21 — the IR21 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from IR21 to each DX region at SFI 118 / Kp 0.67, 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 IR21

A planning heuristic for the local day at IR21, built from sunrise 06:21 UTC, sunset 19:26 UTC, SFI 118, and Kp 0.67. Not a measurement — a starting point for where to listen as the day turns.

Dawn grayline

around 06:21 UTC

40m · 30m · 20m

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

Morning

after 06:21 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

around 19:26 UTC

20m · 40m

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

Night

after 19:26 UTC

40m · 80m

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

Spots touching IR21 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in IR21, IR22, IR20, IR31, IR11. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate IR21 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.
