Vm’el antennae necessitatedfrequent azimuth adjustments so as to maintain the correct line of beartig to the anteue at the Joint Relay Statiov. Shortly after arrival in the operating area, tie OquipMOnt (SCR-608)tobe employed in the Technical Netmre tested. It was found necessaryto relocate and install additional equipments in order to nwet new requirements. In the process of testing, cmsiderable interferencebetween channels and with other equipments was encountered. It was also observed that at certain tties transmissims from the continentalU. S. interfered. When numerous adjustments of frequenciesfailed to eliminate the interferenceproblem, it was found neoessary to revise the en~ire frequencv selecticm for the TechnicalNet and to reduce the original 10-channel system tc a 4-channel system. The RadiologicalNet required for the operation involved the use of a type of H? voice equipment already installed an the major ships. The radiologicalsu-y landing craft and anLOM drone tsnk control craft required HF voice equipments (TCS)which were Installed at Eniwetok by personnel of the BAIROKO, CURTISS and ALBEMARLE. All cf these equipmentswere orystal controlled. The installation and operation of these equipments presented no major problems. One channel of the RadiologicalMet was to be emplo~d as an evacuation circuit for short perioti prior b X, Y, and Z &ys. This neoeesi- tated installatim ofHF voice equipments (TCS) on the AVR-38 and 106 Section xI
