BC-608-A Contactor Unit Clock

Installed in Allied aircraft as part of the Identification, Friend or Foe (IFF) program during World War II, this system would send a signal for 14 seconds of every minute over the pilot's radio to the ground station. The pilot could not speak while the unit was broadcasting. Designed to fit in a standard gauge slot, it has two switches (contactor in or out and clock stop or run), has one small knob (wind), and has clock face that indicates the time the unit is broadcasting.
