What grid square is Istanbul?

KN41 is the live DXRadar reference square for Istanbul. The exact portable or home QTH may vary within the square, but this page tracks the center of KN41 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.

● Best DX Windows from KN41 — Istanbul

Great-circle distance, short-path beam heading, the bands most likely open right now from KN41 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.

Spots touching KN41 and the adjacent squares

These are the newest 10m, 15m, and 20m reports where one side of the path sits in KN41, KN42, KN40, KN51, KN31. This gives the page unique, local context instead of a generic solar snapshot.

No fresh PSKReporter paths are cached for the immediate KN41 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.
