Grid GP18 Band Conditions — Canada
Localized HF conditions for Maidenhead locator GP18. Coordinating at 68.50°, -57.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
GP18 conditions are FAIR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 137.
From Canada operating area, work the 04:41 UTC and 03:09 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses GP18.
10m and 20m are the main daytime rate bands from this part of North America. Watch 10m first if SFI stays elevated.
This square sits in Canada footprint and is best used as a planning center for portable, field-day, and home-station band decisions.

● Best DX Windows from GP18 — Canada operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from GP18 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 GP18
A planning heuristic for the local day at GP18, built from sunrise 04:41 UTC, sunset 03:09 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.
