Task Group. Both Arcw ad
Joint systems, and SIGTOT on- ad
off-line
facilitieswere held, to link CTG 7.4 through the tape relay center
on Eniwetok, with tlw Flagship, Fort Shafter, Hickam Field, Department
of the Air Force, and other ZI imtallations.
Blocks of call signs and call words were obtained and assignments made.
A review of the communicationsproblems encountered in Operation
CROSSROADS revealed that the numerous radio facilities in use
aboami the Flagship resulted in a high degree of interferencedue to
the inherent proximity of the transmitting and receiving antennas. It
,
was therefore decided, for this operation, to instell all high power
radio terminals ashore on Eniwetok
re~
Island. A stamiard joint teletype
center was planned with radio teletype facilities to connect
from there to Kwajalein ad
to Hawdi.
In Hawdi, facilities were
already existing for connection into the Amy
Command ad Administrative
Net (ACAN) for communicationto the United States, Guam ad
other
parts of the world. The Eniwetok center was to be linked to the Flsgship by means of AN/TRC-l equipawmt with provision for both tel~phone
and teletype service through CF-1 and CF-2 carrier equipment. This
link was to be backed up by a low frequency radio teletype circuit
in case of ftiure of the AN/!HZC-lequigmsnt. Sttiby equipmnt was
to be provided on the Flagahip for the voice radio circuit to Kwajalein.
In tiew of the smple radio
ship, the U.S.S. W.
facilities already installed on the Flag-
HCICINIEY,it was not necessary to install
additional facilities other than the AN/TRC-l eq@pmnt
