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.”
The CB Story
1
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 Atmo-
spheric 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.
