Grid QN87 Band Conditions
Localized HF conditions for Maidenhead locator QN87. Coordinating at 47.50°, 157.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
QN87 conditions are POOR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 105.
From the QN87 operating area, work the 19:18 UTC and 07:33 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses QN87.
Night operation should keep 20m on watch and move to 40m as the path darkens.
This square sits in a mixed-region footprint and is best used as a planning center for portable, field-day, and home-station band decisions.

● Best DX Windows from QN87 — the QN87 operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from QN87 to each DX region at SFI 105 / Kp 0.67, 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 QN87
A planning heuristic for the local day at QN87, built from sunrise 19:18 UTC, sunset 07:33 UTC, SFI 105, and Kp 0.67. 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.
