WebPosts: 19020. You can usually zero-beat with WWV by listening to the station's modulated tone and the pulsing of the tone that occurs as you approach the exact frequency. Another method is to watch an S-meter while adjusting frequency you are calibrating, aiming for the slowest "up-down" movement possible.
