What grid square is Shanghai?

PM01 is the live DXRadar reference square for Shanghai. The exact portable or home QTH may vary within the square, but this page tracks the center of PM01 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.

PM01 is currently rated GOOD. The best bands right now are 10m, 12m, 15m, 17m, 20m, with 10m as the main band to watch first.

● Best DX Windows from PM01 — Shanghai

Great-circle distance, short-path beam heading, the bands most likely open right now from PM01 to each DX region at SFI 137 / Kp 2, 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 PM01

A planning heuristic for the local day at PM01, built from sunrise 21:06 UTC, sunset 11:00 UTC, SFI 137, and Kp 2. Not a measurement — a starting point for where to listen as the day turns.

Recent local activity

Spots touching PM01 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in PM01, PM02, PM00, PM11, OM91. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate PM01 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.
