Special calibration radiobeacons, as listed in the current editions of the Coast Guard Light Lists, will broadcast continuously for the purpose of enabling vessels to calibrate their direction finders upon request either to the cognizant District Commander, or, if time does not permit, directly to the calibration station. Signals for requesting calibration service are described in the current editions of the Coast Guard Light Lists. In the case of sequenced radiobeacon stations, continuous transmission for calibration purposes cannot be made without interference resulting with other stations in the same frequency group.
