Abstract : Program V of Joint Task Force Seven was responsible for providing, installing, and operating a radio-controlled timing and firing system. The system was used to supply experimenters with accurate timing signals. The signals were generated by a sequence timer on board the command ship and were transmitted as VHF f-m radio tones which were converted to relay-contact closures by radio-signal receivers at the users' stations. Separate tone generators and transmitters were used for arm, fire, and stop signals, and a triple set of signal receivers at the zero site was suitably interlocked for maximum reliability. Monitoring was provided for power loss at the zero site as well as for the arming and firing functions, position of the arm-clock contacts, presence of salt water in the device, and high voltage on the X-unit.
