What grid square is the PC05 operating area?

PC05 is the live DXRadar reference square for the PC05 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of PC05 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.

From the PC05 operating area, work the 21:46 UTC and 09:53 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses PC05.

Best band now

10m

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

● Best DX Windows from PC05 — the PC05 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from PC05 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 PC05

A planning heuristic for the local day at PC05, built from sunrise 21:46 UTC, sunset 09:53 UTC, SFI 105, and Kp 0.33. Not a measurement — a starting point for where to listen as the day turns.

Spots touching PC05 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in PC05, PC06, PC04, PC15, OC95. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate PC05 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.
