at Eniwetok and a Model 15 teletype was installed in weather centrsl thus providing less than !3minute weather service from Kwa@lein. When the flagship left Pearl Harbor on 8 March 1948, radio teletype communications were maintained through the normal ship-shore facilities to Pearl Harbor. On 10 March 1948, one of the EniwetokOahu radio teletype circuits waa diverted to the flagship. Contact was maintained between the flagship m Eniwetok over this circuit until arrival in the operating area. 0n15 March 1948 this circuit was turned over for regular traff%c. Upon the arrival of the flagship on 16 March 1948, action -s taken to activate all other planned communications facili~ies. A certain amount of difficulty was experienced in the activation of the AN/TRC-l radio links between tb flagship end shore. This difficulty was caused by interference between systems ad interference from other circuits operated from aboard the flagship. Satisfactory operation was soon obtained after selection of suitable frequency combinations. Difficulty was experienced in establishing radio contact with Kwajalein both on the voice circuit and the r~o teletype circuit. This was believed to be caused by the abnormal ionospheric characteristics prevalent during the period of the vernal equinox. The CR’circuit8 were not effected to the degree that the others-were. Although there was some fading ad other disturbance, the operators could generally read the transmissione. A complete check of equipment by competent enldsted acrlofficer personnel as well as civilian technicians ehowed no malfunction. Tests on frequencies other than 127 Section XI
