the Bikini installation.
A redesign of this equipment, to provide for
its independent operation, was accomplished in the forward area utilizing
the spare components of the Bikini and Eniwetok timing systems,
The
system was operationally checked out at Eniwetok prior to its shipment to
Johnston Island.
Late in June 1958, a group of field personnel was sent to Johnston
Island to start field installation of the timing system,
The timing equipment was installed at Station 70 in Building 6002.
Preliminary dry runs started on July 10.
Dry runs and special rehearsal
tests were continued throughout the Teak and Orange series.
A World Time rack identical to that used at EPG on the HERDTACK series
was included in the design of the Johnston timing sytem to record actual.
zero time with respect to WWVH.
This measurement was obtained through
the use of a 10 KC oscillator, driving the World Time clock, syncronized
to WWVH and located in the control room,
The initial flash of the deton-
ation triggered a Fiducial Marker on the roof of the CP,
This in turn
stopped the clock and produced a photographic record of the clock face
at zero time.
Voice-time announcements were made from a script by the timing systen
control operator, referencing the timing sequence indicators,
These
announcements were transmitted to the remote experimenters stations on
153.89MC, 2L3MC, 7H1IKC, and 1,68KC,'
In order to transmit timing signals to the two RB-36 experimenter
stations, a radio timing system was provided.
This system was synchronized
to the master timing system and transmitted various tone frequencies to
radio receivers located aboard the RB-36's, which in turn activated equipment at the station,
