to vessels which might be in an area of reduced visibility, yet, within reception range of a station enjoying clear weather. It further eliminated the personal equation in determining what might or might not be considered reduced visibility. The recommendation that the three Canadian aids maintain a continuous schedule was intended not only to fill a gap in Pacific Coast Radiobeacon System, in the interest of uniformity, but to provide better aids to navigation in a very dangerous area. Headquarters volunteered to lend the Canadian Government equipment for installation in this section. However, the Canadian aids were installed without Coast Guard assistance.

In order to determine whether of not radiobeacons should return to their pre-war schedule, mariners and pilots were asked by Boarding Officers whether they found the peace time operation of radiobeacons of greater value than the continuous fog schedule. Most mariners were of the opinion that better use could be made of them if they were transmitting each minute of the hour. In connection with the airways, Pan American Airways, the Air Transport Command and the Army Service Forces all indicated that marine radiobeacons were used by the pilots and they, too, felt that even better use could be made of them if they were transmitting each minute of the hour. A flight check made at this time on radio marine beacons in Canada found that these aids assisted greatly in safe navigation of aircraft equipped with radio direction finders. Those radiobeacons were operated on a continuous schedule. As a result of these questions and flight tests, it was decided that war time operation of radiobeacon (continuous as for fog) would continue.

Because of the mounting failures of radiobeacons in the District, a survey of radiobeacons and monitor stations was made in February, 1945. All radiobeacon stations were visited and Commanding Officers of each station presented the problems of his activity. As a result of this survey, the following recommendations were presented to the District Coast Guard Officer and later were accepted as District Policy:

(a) A twenty-four hour watch maintained at all radiobeacon and monitor station.

(b) The standby unit swtiched on immediately in case of failure.

(c) The method of timing radiobeacons standardized.

(d) Personnel at all monitor stations thoroughly tested and instructed.
