Field notes from the target list

wwv-10000
WWV time signal — Ticks, 500/600 Hz minute tones, UTC voice each minute. From Europe usually just band.
wwv-10000-na
WWV time signal (North-American receiver) — Heard 2026-09-18 21:40Z, high confidence: 500/600 Hz tones alternating by minute, none in minutes 43-51 (and 29, 59) — avoid those if the tones are the point. Expect keyed-tone.
wwv-5000
WWV time signal, 5 MHz (North-American receiver, night) — Untested. Same format as 10 MHz. Colorado-area receivers all refused API clients on 2026-09-18; Great Lakes / New England delivered. Start at H+07 for the storm / GPS / geoalert speech minutes (H+08..H+18). CHU Canada (3330/7850/14670) is OFF AIR since 2026-06-22 — do not add it back.
