Grid PB17 Band Conditions
Localized HF conditions for Maidenhead locator PB17. Coordinating at -72.50°, 123.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
PB17 conditions are POOR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 105.
From the PB17 operating area, work the 21:32 UTC and 09:51 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses PB17.
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 PB17 — the PB17 operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from PB17 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 PB17
A planning heuristic for the local day at PB17, built from sunrise 21:32 UTC, sunset 09:51 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.
