What grid square is the IB01 operating area?

IB01 is the live DXRadar reference square for the IB01 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of IB01 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 IB01 right now?

IB01 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 06:52 UTC

Sunset 19:27 UTC from IB01

From the IB01 operating area, work the 06:52 UTC and 19:27 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses IB01.

Best band now

10m

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

● Best DX Windows from IB01 — the IB01 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from IB01 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 IB01

A planning heuristic for the local day at IB01, built from sunrise 06:52 UTC, sunset 19:27 UTC, SFI 118, and Kp 0.33. Not a measurement — a starting point for where to listen as the day turns.

Spots touching IB01 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in IB01, IB02, IB00, IB11, HB91. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate IB01 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.
