A communicationcircuit was requested for use between the AVRtS, the Control Station and the AGC-70 This circuit was to employ Navy TCS equipnent and would share one of the frequenciesof the Radiological Net since radiologicalsafetY Per$o~el intended to use the AVRIS after each shot. It was planned to provide communicationsto the final.personnel on the Zero Island by connecting telephones at the Tower Top, Tower Base and T- Station in parallel to an un- attended AN/TRC 1 system working into the Eniwetok telephone switchboard. The communicationsequipment left on the island was to be expended at the time of the shot. The communicationsrequirements of the Radio Chemist~ Group (LAJ-2) were worked out at several conferenceswith scientists of Los Alamos and Military Applications Division, Atcmic Energy Commission, The first of these was held on 14 November 1947 ● Briefly, this grouP planned.to operate a radio-controlledtank on the Zero Island directed from a helicopter. A spare tank was to be carried in a speciallyfitted LCM(6). In case the helicopter equipment failed a second helicopter would be called into service. If the contf’olequipment also failed in the second helicopter, the tank could be controlled from the LCM where the operator would be voice directed from the helicopter. SCR-300 conmmnicationwas planned between the LCM and the island party required to start the tank. VHF equipnentwas to be used between the LCM, helicopters and the CVE-115. The LCMwas also equipped with an SCR-608 in the Technicsl Net for general communications. The communicationsrequired by the Neutron MeasurementGroup . 46 Section XI . - P
