What grid square is the PO13 operating area?

PO13 is the live DXRadar reference square for the PO13 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of PO13 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 PO13 right now?

PO13 is currently rated FAIR. The best bands right now are 10m, 20m, 30m, 40m, 60m, with 10m as the main band to watch first.

Sunrise 21:33 UTC

Sunset 09:50 UTC from PO13

From the PO13 operating area, work the 21:33 UTC and 09:50 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses PO13.

Best band now

10m

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

● Best DX Windows from PO13 — the PO13 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from PO13 to each DX region at SFI 104 / Kp 0, 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 PO13

A planning heuristic for the local day at PO13, built from sunrise 21:33 UTC, sunset 09:50 UTC, SFI 104, and Kp 0. Not a measurement — a starting point for where to listen as the day turns.

Dawn grayline

around 21:33 UTC

40m · 30m · 20m

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

Morning

after 21:33 UTC

20m · 15m

Modest SFI — 20m is the daytime workhorse here.

Midday

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

Dusk grayline

20m · 40m

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

Night

after 09:50 UTC

40m · 80m

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

Spots touching PO13 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in PO13, PO14, PO12, PO23, PO03. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate PO13 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.
