Grid QF39 Band Conditions — Australia
Localized HF conditions for Maidenhead locator QF39. Coordinating at -30.50°, 147.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
QF39 conditions are POOR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 105.
From Australia operating area, work the 20:03 UTC and 08:08 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses QF39.
10m is the first place to check for long-haul openings from this region, with 15m close behind.
This square sits in Australia footprint and is best used as a planning center for portable, field-day, and home-station band decisions.

● Best DX Windows from QF39 — Australia operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from QF39 to each DX region at SFI 105 / Kp 1.33, 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 QF39
A planning heuristic for the local day at QF39, built from sunrise 20:03 UTC, sunset 08:08 UTC, SFI 105, and Kp 1.33. 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.
