What grid square is the FI31 operating area?

FI31 is the live DXRadar reference square for the FI31 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of FI31 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.

What bands are open in FI31 right now?

FI31 is currently rated POOR. The best bands right now are 10m, 20m, 30m, 40m, 60m, with 10m as the main band to watch first.

Sunrise 10:43 UTC

Sunset 22:49 UTC from FI31

From the FI31 operating area, work the 10:43 UTC and 22:49 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses FI31.

Best band now

10m

Night operation should keep 20m on watch and move to 40m as the path darkens.

● Best DX Windows from FI31 — the FI31 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from FI31 to each DX region at SFI 105 / 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.

● Band-by-Time Plan for FI31

A planning heuristic for the local day at FI31, built from sunrise 10:43 UTC, sunset 22:49 UTC, SFI 105, and Kp 2. Not a measurement — a starting point for where to listen as the day turns.

Spots touching FI31 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in FI31, FI32, FI30, FI41, FI21. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate FI31 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.
