Grid CN94 Band Conditions — Portland
Localized HF conditions for Maidenhead locator CN94. Coordinating at 44.50°, -121.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
CN94 conditions are FAIR. Best bands: 10m, 12m, 15m, 17m, 20m. SFI: 137.
From Portland, work the 12:40 UTC and 03:42 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses CN94.

● Best DX Windows from CN94 — Portland
Great-circle distance, short-path beam heading, the bands most likely open right now from CN94 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 CN94
A planning heuristic for the local day at CN94, built from sunrise 12:40 UTC, sunset 03:42 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.
