Grid QH17 Band Conditions — Australia
Localized HF conditions for Maidenhead locator QH17. Coordinating at -12.50°, 143.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
QH17 conditions are FAIR. Best bands: 10m, 12m, 15m, 17m, 20m. SFI: 137.
From Australia operating area, work the 20:50 UTC and 08:20 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses QH17.
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 QH17 — Australia operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from QH17 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 QH17
A planning heuristic for the local day at QH17, built from sunrise 20:50 UTC, sunset 08:20 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.
