What grid square is the KR81 operating area?

KR81 is the live DXRadar reference square for the KR81 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of KR81 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 KR81 right now?

KR81 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 02:52 UTC

Sunset 16:00 UTC from KR81

From the KR81 operating area, work the 02:52 UTC and 16:00 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses KR81.

Best band now

10m

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

● Best DX Windows from KR81 — the KR81 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from KR81 to each DX region at SFI 105 / Kp 0.33, 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.

● Band-by-Time Plan for KR81

A planning heuristic for the local day at KR81, built from sunrise 02:52 UTC, sunset 16:00 UTC, SFI 105, and Kp 0.33. Not a measurement — a starting point for where to listen as the day turns.

Dawn grayline

around 02:52 UTC

40m · 30m · 20m

Grayline enhancement — low bands reach long distances as the terminator passes.

Morning

after 02:52 UTC

20m · 15m

Modest SFI — 20m is the daytime workhorse here.

Midday

local noon

15m · 20m

20m and 15m carry the daytime load at this SFI.

Dusk grayline

around 16:00 UTC

20m · 40m

Second grayline peak — 20m holds, then hands off to 40m.

Night

after 16:00 UTC

40m · 80m

Low bands own the darkness — 40m for DX, 80m regional.

Recent local activity

Spots touching KR81 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in KR81, KR82, KR80, KR91, KR71. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate KR81 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.
