Inside Back Cover The CB Story The CB Story The Citizens Band lies between the shortwave broadcast and 10-meter Amateur radio bands, and was established by law in 1949. The Class D two-way communications service was opened in 1959. (CB also includes a Class A citizens band and Class C remote control frequencies.) FCC regulations permit only “transmissions” (one party to another) rather than “broadcasts” (to a wide audience). Thus, advertising is not allowed on CB Channels because that is “broadcasting.” Replacement or substitution of transistors, regular diodes or other parts of a unique nature, with parts other than those recommended by Cobra Electronics, may cause violation of the technical regulations of Part 95 of the FCC Rules, or violation of Type Acceptance requirements of Part 2 of the Rules. Citizens Band (CB) Radio operators are no longer required to obtain an FCC license to operate their CB equipment or provide station identification. Nevertheless, an operator of a CB radio station is still required to comply with the communications act and with the rules of CB Radio Operation. What Is Weather Radio? NOAA WEATHER RADIO (NWR) is a service of the National Oceanic and Atmospheric Administration (NOAA), of the U.S. Department of Commerce. It provides continuous, around-the-clock broadcasts of the latest weather information directly from National Weather Service Offices. The broadcasts are tailored to the weather- information needs of people within the receiving area. For example, coastal and Great Lakes' stations provide specialized weather information for area boaters, fishermen and others engaged in marine activities, as well as general weather information for the public-at-large. Three hundred eighty (380) NWR stations are in operation by the U.S. Government in addition to several NWR stations that are maintained by private interest groups. Under a January 1975 White House policy statement, NOAA Weather Radio was designated as the sole Government operated radio system to provide direct warnings into private homes for both natural disasters and nuclear attack. The capability is to supplement warnings by sirens and by commercial radio and television. NWR Frequencies and Transmission Characteristics NWR broadcasts have been allocated seven frequencies within the VHF radio spectrum reserved for Government use. Assigned frequencies are: 162.400 MHz 162.475 MHz 162.525 MHz 162.425 MHz 162.500 MHz 162.550 MHz 162.450 MHz 1 Section I Introduction Section I Introduction FREQUENCY RANGE The COBRA 2010 GTL WX transceiver represents one of the most advanced AM base station radios used as a Class D station in the Citizens Radio Service.
