NOAA Weather Radio (NWR) is an operational program of the National
Weather Service (NWS). The National Weather Service, an organizational
entity of the National Oceanic and Atmospheric Administration (NOAA),
United States Department of Commerce, operates the Weather Forecast
Offices throughout the United States and its possessions. Broadcasts
of routine weather information, weather forecasts, and warnings
of severe weather originate at each Weather Forecast Office.
A NOAA Weather Radio receiver is one that is capable
of receiving weather and/or warning information from NWS Weather
Forecast Offices, approved Department of Homeland Security offices
responsible for the dissemination of warning information, and those
Emergency Operation Centers that have been specifically authorized
to disseminate warnings on the NWR operational frequencies.
NWR provides 24 hour broadcasts of local weather
information and warnings of severe weather specific to each of its
broadcast locations. The NWR program also has the distinction of
providing warning information for any and all hazards that may affect
the communities served by local NWR broadcasts, as well as warnings
that are disseminated on a state and/or national level. The scope
of the all hazard warnings include both natural and man made situations
that would mandate notification and/or advisories to citizens in
the broadcast area. State and national warnings also include terrorist
activity and/or situations of civil unrest. The warning situations
mentioned herein are not all inclusive but go to defining the scope
of the warning capabilities of NWR.
The NWR All Hazards logo is a registered trade mark
of the National Weather Service. Any request for the use of this
logo must be in writing (see application at http://www.weather.gov/nwr/allhazard_logo_info.htm).
Authorization to use the NWR All Hazards logo will be in writing
and specific to model of equipment or specific events or activity.
Use of this logo on warning devices stipulates that
the product which displays this symbol will reliably provide the
services mentioned above. Manufacturers that submit their products
for assessment and evaluation for use of the NWR All Hazards logo
are responsible for ensuring their products meet the minimum requirements
for alert receivers as specified in the Consumer Electronics Association
(CEA) Standard 2009-A (or the current revision thereof). The NWR
Program Office will evaluate each receiver that is submitted for
authorization to use the logo to ensure compliance with the CEA
It must be noted that the NWR Program Office is not
a testing facility or certification laboratory. Manufacturers submitting
product samples to the NWR Program Office for evaluation for use
of the NWR logo should not expect to receive certification of their
product. Product certification remains the responsibility of the
manufacturer. The NWR Program Office will verify manufacturers testing
and certification and their product’s compliance with the
specifications contained in CEA 2009-A. To assist the NWR Program
Office in verification of compliance, the manufacturer is required
to submit a copy of their internal test results of the product as
they relate to the specifications contained in CEA 2009-A. To order
CEA 2009-A, go to http://global.ihs.com
Product samples submitted to the NWR Program Office
for evaluation must be fully operational and perform as described
in the owner’s manual (also submitted with samples). Pre-production
samples may be submitted, at the discretion of the manufacturer,
but the weather band receiver and warning devices must function
properly, as described in the owners manual and meet the specifications
detailed in CEA 2009-A. Any pre-production products and/or documentation
submitted to the NWR Program Office will not be disclosed to any
other parties and will be maintained by the NWR Program Office as
The NWR Program Office will, at its discretion, forward
product samples to an independent laboratory for comprehensive testing
and evaluation to determine compliance with the CEA 2009-A specifications.
Should a submitted product fail to meet the specifications of the
CEA 2009-A specification, the NWR Program Office will advise the
manufacturer of testing results. Products may be re-submitted to
the NWR Program Office for evaluation upon correction of deficiencies
noted during evaluation.
NOAA Weather Radio All Hazards receivers operate
on 7 channels in the 162 Megahertz band. The channels are 162.400,
162.425, 162.450, 162.475, 162.500, 162.525, and 162.550 MHz. The
NWR All Hazards receiver must be capable of selecting all 7 channels.
NWR broadcasts 24 hours a day, 7 days a week from FM transmitters
located throughout the United States and its territories.
In addition, NWR receivers produce an audible warning
tone and a visual warning light or L.E.D. These warning devices
activate when the receiver receives a warning signal from the broadcast
location. When a broadcast is designed to activate a warning device
on a NWR receiver, a 1050 Hz tone is transmitted from the broadcast
location which, in turn, activates the warning devices on the NWR
receiver. If the NWR receiver is in a “stand-by” mode,
the activation of the warning devices will cause the receiver to
switch to active mode.
The NWR receiver will also provide, at a minimum,
text description of the event that caused the activation of the
warning device. Devices that incorporate other features, such as
AM/FM radios, will often cause the additional feature to mute and
allow the warning broadcast to be heard in its place for a set duration
of time. When a warning is received, the listener will be able to
listen to the live warning broadcast on the receiver.
Unless the receiver is a hand-held or vehicle mounted
model, the NWR receiver will be powered by standard household current
and incorporate a battery back-up power supply. Receivers that incorporate
a hand-cranked generator for power in emergency situations will
also have an AC power adapter that will supply normal household
The most desired feature of NWR All Hazards receivers
is Specific Area Message Encoding (S.A.M.E.). S.A.M.E. is the digitally
encoded feature that allows NWR All Hazards receivers to alert only
to warnings that are specific to a location, It also allow the receiver
to program “Event Codes” that provide warnings for man-made
as well as weather related hazards. Many of these warnings are generated
from Emergency Managers and Homeland Security agencies. Obtain more
information and technical requirements on S.A.M.E. at http://www.weather.gov/nwr/nwrsame.htm.
Transmission of a digital code will prompt NWR All
Hazard S.A.M.E. receivers to activate and cause the receiver to
produce audible and visual warning signals. There are three colors
of warning lights that correspond to weather statements, weather
watches, and weather warnings that are broadcast by the Weather
Forecast Office when S.A.M.E. is activated. Transmission of a digitally
encoded event code determines which color warning light is activated
and is the basis for the all hazards features of the NWR receiver.
CEA 2009-A provides extensive technical parameters for S.A.M.E.
NWR All Hazards receivers may be combined in products
that incorporate other features. Receivers may be vehicle mounted,
Citizen Band receivers, components of televisions and computers,
AM/FM radios, and a myriad of other features and functions. The
evaluation of the receiver for use of the NWR logo will only concentrate
on the weather band receiver.
Application for use of the NWR All Hazards logo may
be submitted for logo display on warning alert equipment (and associated
packaging), educational and/or promotional materials, web pages,
and other equipment and/or material that promote NOAA Weather Radio.
