What grid square is the DA10 operating area?

DA10 is the live DXRadar reference square for the DA10 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of DA10 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 DA10 — the DA10 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from DA10 to each DX region at SFI 148 / Kp 1, 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.
