§ 62.55 - General.

Maritime radiobeacons operate during specific intervals as published in Coast Guard Light Lists. For station identification, simple characteristics consisting of combinations of dots and dashes are used. The characteristics of marker-beacons are composed of series of dashes for part of a 15 second cycle, which is followed by a silent period to complete the cycle. The transmitted power of maritime radiobeacons is adjusted to provide a useable signal at the service range which meets the operational requirement. Marker-beacons are of low power for local use only. Coast Guard maritime radiobeacons operate within the frequency band 275-335 kilohertz.
