What grid square is the QA73 operating area?

QA73 is the live DXRadar reference square for the QA73 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of QA73 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.

Sunrise 18:49 UTC

Sunset 08:18 UTC from QA73

From the QA73 operating area, work the 18:49 UTC and 08:18 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses QA73.

Best band now

10m

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

● Best DX Windows from QA73 — the QA73 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from QA73 to each DX region at SFI 115 / 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.

● Band-by-Time Plan for QA73

A planning heuristic for the local day at QA73, built from sunrise 18:49 UTC, sunset 08:18 UTC, SFI 115, and Kp 0.67. Not a measurement — a starting point for where to listen as the day turns.

Spots touching QA73 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in QA73, QA74, QA72, QA83, QA63. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate QA73 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.
