What grid square is the HA85 operating area?

HA85 is the live DXRadar reference square for the HA85 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of HA85 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 DX Windows from HA85 — the HA85 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from HA85 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.
