Grid GP28 Band Conditions — Canada
Localized HF conditions for Maidenhead locator GP28. Coordinating at 68.50°, -55.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
GP28 conditions are FAIR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 137.
From Canada operating area, work the 04:33 UTC and 03:01 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses GP28.
After sunset, 20m transitions and 40m becomes the reliable DX fallback from this part of North America.

● Best DX Windows from GP28 — Canada operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from GP28 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 GP28
A planning heuristic for the local day at GP28, built from sunrise 04:33 UTC, sunset 03:01 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.
