Rugby Clock - Component Schedule
Parts List (and Maplin part codes)
Note: the MSF aerial and module are no longer available from Maplin. They are available from http://www.atomic-clock.galleon.eu.com/msf-receiver/msf-receiver.html but quite costly (~£50). Alternatively modules can be found in some Radio Controlled Clocks.
