Grid KN12 Band Conditions — Sofia
Localized HF conditions for Maidenhead locator KN12. Coordinating at 42.50°, 23.00°. Updated with real-time telemetry from NOAA and DX cluster reports.
KN12 conditions are POOR. Best bands: 10m, 20m, 30m, 40m, 60m. SFI: 104.
From Sofia, work the 04:16 UTC and 16:28 UTC grayline windows: probe 20m, 30m, and 40m in the 15 minutes either side while the terminator crosses KN12.
European evening operation usually shifts toward 20m and 40m once the high bands soften.
This square sits in Western/Central Europe footprint and is best used as a planning center for portable, field-day, and home-station band decisions.

● Best DX Windows from KN12 — Sofia
Great-circle distance, short-path beam heading, the bands most likely open right now from KN12 to each DX region at SFI 104 / Kp 0, 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 KN12
A planning heuristic for the local day at KN12, built from sunrise 04:16 UTC, sunset 16:28 UTC, SFI 104, and Kp 0. 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.
