What grid square is USA operating area?

EN86 is the live DXRadar reference square for USA operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of EN86 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

After sunset, 20m transitions and 40m becomes the reliable DX fallback from this part of North America.

● Best DX Windows from EN86 — USA operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from EN86 to each DX region at SFI 105 / Kp 1.33, 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.
