Grid NK33 Band Conditions — South Asia
Localized HF conditions for Maidenhead locator NK33. Coordinating at 13.50°, 87.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
NK33 conditions are FAIR. Best bands: 10m, 12m, 15m, 17m, 20m. SFI: 137.
From South Asia operating area, work the 23:55 UTC and 12:43 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses NK33.
Local evening usually favors 20m first, then 40m as absorption drops.

● Best DX Windows from NK33 — South Asia operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from NK33 to each DX region at SFI 137 / Kp 3, 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 NK33
A planning heuristic for the local day at NK33, built from sunrise 23:55 UTC, sunset 12:43 UTC, SFI 137, and Kp 3. Not a measurement — a starting point for where to listen as the day turns.
Grayline enhancement — low bands reach long distances as the terminator passes.
High bands rising with the sun; check 10m for DX.
Peak high-band window — 10m and 15m open widest.
Second grayline peak — 20m holds, then hands off to 40m.
Low bands own the darkness — 40m for DX, 80m regional.
