Where severe weather or hurricanes are a frequent problem, the majority of NWS offices have direct amateur assistance. Often this includes the operation of amateur equipment by a licensed amateur in the NWS office. All classes of licenses require passing an International Morse Code test and a written examination on radio theory, practical radio operations, equipment adjustment, and FCC regulations. Amateur communications cover a broad spectrum of capabilities. Certain bands are especially suited for mobile communications, while others provide nationwide or international coverage.
Amateur communications are normally well organized and highly disciplined.
2.2 Citizen's Band Service . The CB operator is not required to pass any written test on the technical aspects of radio nor required to have any knowledge of International Morse Code. Power limitations and band characteristics normally limit direct communications ranging from 5 to 30 miles. At times, distances may be much greater, but it is illegal to exceed 150 miles. 3.1 Amateur Radio Service.
