Field notes from the target list

wwv-hamsci-10000: WWV HamSCI test signal (minute 8) — The most composed thing NIST transmits and the only sweep on a time station: white noise, up/down chirps and amplitude/frequency-varying tones, every hour at minute 8 since 2021-11-15, still running 2026. Three minutes is enough. Expect data/keyed-tone.
