● Best DX Windows from HM54 — the HM54 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from HM54 to each DX region at SFI 105 / Kp 0.67, 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.
