                    Subpart C--Maritime Radiobeacons
 
Sec. 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.
