Grid PH70 Band Conditions — Australia
Localized HF conditions for Maidenhead locator PH70. Coordinating at -19.50°, 135.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
PH70 conditions are POOR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 105.
From Australia operating area, work the 20:51 UTC and 08:57 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses PH70.
Local evening usually favors 20m first, then 40m as absorption drops.
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 PH70 — Australia operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from PH70 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 PH70
A planning heuristic for the local day at PH70, built from sunrise 20:51 UTC, sunset 08:57 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.
