What grid square is the CR11 operating area?

CR11 is the live DXRadar reference square for the CR11 operating area. The exact portable or home QTH may vary within the square, but this page tracks the center of CR11 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 CR11 right now?

CR11 is currently rated FAIR. The best bands right now are 10m, 20m, 30m, 40m, 60m, with 10m as the main band to watch first.

● Best DX Windows from CR11 — the CR11 operating area

Great-circle distance, short-path beam heading, the bands most likely open right now from CR11 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 CR11

A planning heuristic for the local day at CR11, built from sunrise 14:33 UTC, sunset 03:30 UTC, SFI 115, and Kp 0.67. Not a measurement — a starting point for where to listen as the day turns.

Recent local activity

Spots touching CR11 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in CR11, CR12, CR10, CR21, CR01. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate CR11 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.
