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 ser-
vice was opened in 1959. (CB also includes a Class A citizens band and Class C remote
control frequencies.)
FCC regulations permit only ÒtransmissionsÓ (one party to another) rather than
ÒbroadcastsÓ (to a wide audience). Thus, advertising is not allowed on CB Channels
because that is Òbroadcasting.Ó
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 pro-
vides 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 LakesÕ stations provide specialized weather information for area boaters,
fishermen and others engaged in marine activities, as well as general weather infor-
mation for the public-at-large. Three hundred eighty (380) NWR stations are in oper-
ation by the U.S. Government in addition to several NWR stations that are main-
tained by private interest groups.
Under the January 1975 White House policy statement, NOAA Weather Radio was des-
ignated 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 sup-
plement warnings by sirens and by commercial radio and television.
NWR Frequencies and Transmission Characters
NWR broadcasts have been allocated seven frequencies within the VHF radio spec-
trum 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
Replacement or substitution of transistors, regular diodes or other parts of a unique nature, with parts other
than those recommended by Cobra, 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.

“Cuts Static coming in, adds Punch going out!”
Cobra proudly introduces the first Patent Pending technology that dramatically
improves the transmission and reception of CB radio signals.
This revolutionary system reconfigures the transmission signal which allows it to be
transferred more effectively through cluttered airwaves. It literally ÒpunchesÓ your
message through the hundreds of thousands of signals that are in the air. At the same
time,
SoundTracker
system dynamically adjusts the relationship between the signal
and static commonly referred to as noise. This allows CobraÕs
SoundTracker
system to
significantly reduce the amount of static on all incoming CB signals. The system can be
further optimized when two SoundTracker CBÕs are used to talk to each other.
The end result is a clearer, cleaner sounding reception of signals and more powerful
transmissions which
dramatically
improve CB Communications
