Broadcast Format
On top of the standard carrier frequencies, WWV carries additional information using standard double-sideband amplitude modulation. WWV's transmissions follow a regular pattern repeating each minute. They are coordinated with its sister station WWVH to limit interference between them. Because they are so similar, both are described here.
| Second | WWV | WWVH |
|---|---|---|
| 0–1 | Minute beep (0.8 s) | |
| 1–45 | Standard tone or voice announcement | |
| 45–52.5 | Silence (except tick) | Voice time announcement |
| 52.5–60 | Voice time announcement | Silence (except tick) |
