I have two; one is a bedside alarm clock, the other is on the wall, a combination indoor/outdoor thermometer and digital clock. My understanding is that the signal is WWVB which is in Fort Collins, Colorado. I'm in the San Francisco area and it surprises me that the signal can be read all the way out here. And I guess it works for the East Coast as well. Wikipedia says, "Fort Collins is situated at the base of the Rocky Mountain foothills of the northern Front Range, approximately 60 miles (97 km) north of Denver, Colorado, and 45 miles (72 km) south of Cheyenne, Wyoming. Elevation is
4,982 ft (1,519 m) above sea level." How that signal makes it across the Sierras here in California beats me; ionosphere bouncing?
