Commuaication with Lt Col Collison, TG 132.2, will be effected through the command net on 27.2 Mc (SCR 508, CIC, USS Rendova). 8. Mr. Fussell will be aboard the USS Rendova with a Motorola walkie-talkie for communication with the USS Estes. He will keep in touch with Maj Servis. C.15.2 Parry-based Operations 1. All helicopters will operate on 120.06 Mc, and TU 7 will furnish Parry Air Operations aman to copy Rad-Safe messages over the helicopter net. A direct landline telephone connects C.15.3 Messages 1. The code given below for reporting radiation intengities and isiand names will be used on low-frequency <adio nets. For VHF circuits (AN/TRC, SCR 508, SCR 300, helicopter radio) and telephones, it is not necessary to encode the name of the island beyond the Restricted code, e.g., Alice, Belle, Clara, etc. It will be the responsibility of the monitor originating the message to ensure that a mersage using the names Alice, Belle, ¢tc., will not be sent via low-frequency radio (Le., Motorola and ship c-w circuits). Note that this would occur only in the event that our normal VHF radio channels failed and it became necessary to send the message through a communications center not under our control. 2. Atypical message for VHF circuits then would be made up as follows: Time Island Map Coordinates Scale, Intensity 1430 Janet 3 1 2 60-75 15-22 22-20 Wi5 T 35 T 40 Wi5 Shonayeegota In this case, where only one photo is used to cover the island, it is not necessary to give a map numberafter the code namefor the island. If the grid coordinates are omitted, the reported intensity will be assumed to be relatively uniform throughout the island. The coordinates for a given location will be determined by placing an overlay over the photo and reading first to the right and then up in rormal fashion, i.e., “read right up.” The following revised code will be used to report radiation intensities and location by TU 7 Rad-Safe personnel. . pec ene ene ‘a 16-24 LX, Alice ey eae ee 1430 ae - The above message gives several locations and their intensities. The number under “Map” indicates the photo numbersince in some cases more than one aerial photo is necessary to cover the island. The headings for the groups are not transmitted. Thus a message would be sent as follows: 77 arene cet a Ren Parry Air Operations with Building 57, Parry. 2. An SCR 508 installed in Building 57 will take over the function of the SCR 508, CIC (USS Rendova), described in 3 and 5, See. C.15.1. 3. A direct landline telephone from Building 57 to CDR Maynard (Compound) will replace the AN/TRC radiotelephone circuit.
