What grid square is the PO83 operating area?

PO83 is the live DXRadar reference square for the PO83 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of PO83 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 PO83 right now?

PO83 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 20:37 UTC

Sunset 08:54 UTC from PO83

From the PO83 operating area, work the 20:37 UTC and 08:54 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses PO83.

Best band now

10m

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

● Best DX Windows from PO83 — the PO83 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from PO83 to each DX region at SFI 105 / 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 PO83

A planning heuristic for the local day at PO83, built from sunrise 20:37 UTC, sunset 08:54 UTC, SFI 105, and Kp 0.67. Not a measurement — a starting point for where to listen as the day turns.

Dawn grayline

around 20:37 UTC

40m · 30m · 20m

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

20m · 15m

Modest SFI — 20m is the daytime workhorse here.

Midday

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

Night

Spots touching PO83 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in PO83, PO84, PO82, PO93, PO73. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate PO83 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.
