What grid square is the RQ37 operating area?

RQ37 is the live DXRadar reference square for the RQ37 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of RQ37 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 RQ37 right now?

RQ37 is currently rated FAIR. The best bands right now are 10m, 20m, 30m, 40m, 60m, with 10m as the main band to watch first.

From the RQ37 operating area, work the 18:27 UTC and 07:04 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses RQ37.

Best band now

10m

10m is the headline band right now, with 20m as the dependable fallback if conditions soften.

● Best DX Windows from RQ37 — the RQ37 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from RQ37 to each DX region at SFI 118 / 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 RQ37

A planning heuristic for the local day at RQ37, built from sunrise 18:27 UTC, sunset 07:04 UTC, SFI 118, and Kp 0.33. Not a measurement — a starting point for where to listen as the day turns.

Dawn grayline

around 18:27 UTC

40m · 30m · 20m

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

Morning

after 18:27 UTC

20m · 15m · 10m

High bands rising with the sun; check 10m for DX.

Midday

local noon

10m · 15m · 20m

Peak high-band window — 10m and 15m open widest.

Dusk grayline

around 07:04 UTC

20m · 40m

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

Night

after 07:04 UTC

40m · 80m

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

Recent local activity

Spots touching RQ37 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in RQ37, RQ38, RQ36, RQ47, RQ27. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate RQ37 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.
