What grid square is the IB58 operating area?

IB58 is the live DXRadar reference square for the IB58 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of IB58 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.

Best band now

10m

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

● Best DX Windows from IB58 — the IB58 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from IB58 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.
