Grid GD26 Band Conditions — South America
Localized HF conditions for Maidenhead locator GD26. Coordinating at -53.50°, -55.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
GD26 conditions are FAIR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 137.
From South America operating area, work the 11:40 UTC and 19:54 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses GD26.
10m is the headline band right now, with 20m as the dependable fallback if conditions soften.
This square sits in South America footprint and is best used as a planning center for portable, field-day, and home-station band decisions.

● Best DX Windows from GD26 — South America operating area
Great-circle distance, short-path beam heading, the bands most likely open right now from GD26 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 GD26
A planning heuristic for the local day at GD26, built from sunrise 11:40 UTC, sunset 19:54 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.
