This programme begins with an illustrated call for entries for the Memory of the Millennium competition (programmes and stations that no longer exist) and then moves into a feature about the time signal station WWV and WWVH in Fort Collins, Colorado, USA. Thanks to Alfonso Montelegre for grabbing the interview material (he went to Fort Collins, not me) and also to the late Dave Rosenthal who shared a fascination in these ticking clocks. These stations now have a website full of photos and even more technical background than we had time for. Check out http://tf.nist.gov/stations/wwvh.htm
