It took approximately eight months for the delivery of the major ANRAC items to the District and it was not until March, 1944, that the first two ANRAC equipped buoys were placed on station. All maintenance and repair work for this initial installation of special buoy equipment was handled at the Tongue Point Repair Base. Maintenance personnel from this yard kept a running record sheet of both buoys together with a battery record for which a new calendar marking system was adopted. The ANRAC equipped buoys were placed on station in accordance with the normal buoy replacement schedule and for this reason, although other buoys were equipped with the ANRAC receivers at that time, they were not set out.
In the meantime, the Commandant, 13th Naval District, had ordered the relighting of buoys in Grays Harbor and Willapa Bay Areas which had been blacked out for security. This action was necessary to facilitate the movement of marine traffic related to the war effort. On the other hand, experience had demonstrated that certain hazards to defense activities were created by the inability to black out lights promptly. Since the lights in this area might have been of inestimable value to hostile craft, and, in order to circumvent any such use being made of the lights, it appeared necessary that arrangements be made for their blacking out expeditiously. Experience had further demonstrated the impracticability of getting the lights extinguished in any kind of reasonable time, except for shooting them out. In one test case, it was a matter of five days before some of the buoys could be approached without the possibility of seriously damaging a boat or buoy or injuring personnel. For these reasons, the District Coast Guard Officer requested Headquarters to install ANRAC on the following lights where other means could not be utilized to obtain reasonable prompt extinguishment:

Headquarters approved the Grays Harbor and Willapa Bay Project, but, the equipment was held up until the middle of 1944. (The buoys were meanwhile equipped with brackets so that installation could be completed shortly after receipt of the transmitters.) Headquarters also indicated at that time that ANRAC installations, other than Columbia Bar, had not been anticipated for the 13th Naval District and that since ANRAC had been developed principally because of potential hostile air attacks, it was to be applied only to those unattended lights on floating and fixed aids which were grouped to form patterns giving lines of orientation. It was not to be applied to relight or control lights of comparatively low intensity which were not readily recognizable to locate strategic areas or indicate definite bearings. Headquarters advised that further requests for ANRAC installations would not be favorably received.
By early 1944, blackout requirements in certain areas were materially reduced but no indication existed that such restrictions might not again be imposed. It was, therefore, desirable to continue the ANRAC program. The Coast Guard investment in ANRAC represented a considerable amount and a fair test of ANRAC in localities adjacent to better service facilities was necessary, in any case, to accomplish the ANRAC program as planned and to prove the equipment for use in remote areas where need for same continued to exist. Headquarters realized the difficulties encountered in pursuing the program due to shortage of servicing facilities but it desired that the ANRAC program be brought to a logical conclusion. ANRAC installations were modified only to the extent that aids of lesser importance were ANRAC equipped and field tested before the program was extended to include all aids in the original plan. Sufficient aids of lesser importance were field tested to determine the effectiveness of ANRAC under varying conditions. Daily preliminary tests of ANRAC equipment on the Columbia River bar buoys indicated that their performance was entirely satisfactory. However, due to the fact that there was probably less that 5% of the time in the fall of the year and continuing through the winter that all of the controlled buoys could be seen from Cape Disappointment, it appeared that a questionable situation would be created by extinguishing the lights on these buoys

daily and then having no assurance that relighting was accomplished. In order to verify the conditions that existed in connection with this situation, visibility tests were made on all ten buoys twice each day without the use of control equipment. A tabulation sheet showing all ten controlled buoys, the date and hour, an indication of each buoy light that was visible before 0800 and after 1200 each day was submitted to the District Coast Guard Office weekly. In 3920 observations, lights were visible by telescope from Cape Disappointment Lookout Station only 2900 times. This figure included all ten buoys listed on the previous page, during period from 17 July, 1944, to 12 February, 1945, at which time the visibility tests were discontinued.
By November, 1944, Headquarters became interested in the peace time value of ANRAC and requested that the District Coast Guard Officer prepare a list of such locations in the 13th Naval District where ANRAC could be used for peace time operation. The major complicated features (essential for security) were to be simplified to meet peace time application to unattended radiobeacons or fog signals where maintenance by an operating crew and expenses related thereto presented objectionable difficulties. In response, the District Coast Guard Office listed five fog signals near the mouth of the Columbia River within a three mile radius from Point Adams Lifeboat Station, Hammond, Oregon, and the fog signals at Tacoma Waterway, Milwaukie Shoal and Point Defiance all within a radius of 4 1/2 miles of Browns Point Light near Tacoma, Washington. However, the District Coast Guard Officer did not feel that ANRAC control of shore lights during peace time would have any advantage over the sun relays currently installed due to the higher cost and a greater possibility for human error.
Headquarters was requested, since the war time ANRAC program had proved unsatisfactory, that authority to discontinue the radio control of the lights on the buoys at the entrance to the Columbia River be granted. Due to the fact

that an outage on any one of these buoys created a difficult situation and also because the necessity for an emergency blackout seemed extremely doubtful, this action seemed practicable. At the same time, it was requested that Headquarters postpone indefinitely the installation of the ANRAC equipment on buoys at the entrance of Willapa Bay and Grays Harbor as the equipment had not yet been placed on the buoys due to delay in installing the related control equipment on shore. This action, to remove ANRAC from Columbia River, Grays Harbor and Willapa Bay, was approved but the request for the installation of ANRAC on the five fog signals was not. Authority was granted, however, to equip Browns Point Light Station, newar Tacoma, Washington, as a control point for fog signals at Tacoma Waterway, Alki Point, near Seattle, Washington, as control station for Duwamish Head Fog Signal, Point No Point, Hansville, Washington, as control station for Double Bluff Lighted Trumpet Buoy and Point Adams, Hammond, Oregon, as control station for Desdemona Sands Fog Signal. A form No. 2609 for the installation at Duwamish Head was forwarded to Headquarters. No further action was taken by the District Coast Guard Officer on other points approved by Headquarters.
