● Best DX Windows from IO81 — Birmingham

Great-circle distance, short-path beam heading, the bands most likely open right now from IO81 to each DX region at SFI 137 / Kp 2, 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.

Recent local activity

Spots touching IO81 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in IO81, IO82, IO80, IO91, IO71. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate IO81 footprint right now. That usually means you should widen the search to the nearest regional hubs below or fall back to 20m/40m for the next operating window.
