Grid DP78 Band Conditions — Canada
Localized HF conditions for Maidenhead locator DP78. Coordinating at 68.50°, -105.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
DP78 conditions are POOR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 105.
From Canada operating area, work the 12:42 UTC and 01:05 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses DP78.
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 DP78 — Canada operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from DP78 to each DX region at SFI 105 / Kp 0.33, 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 DP78
A planning heuristic for the local day at DP78, built from sunrise 12:42 UTC, sunset 01:05 UTC, SFI 105, and Kp 0.33. 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.
Modest SFI — 20m is the daytime workhorse here.
20m and 15m carry the daytime load at this SFI.
Second grayline peak — 20m holds, then hands off to 40m.
Low bands own the darkness — 40m for DX, 80m regional.
