NOAA Weather Radio All-Hazards (NWR) is the "voice of the National Weather Service" and serves as the agency's primary means of communicating around-the-clock weather information to the public. NWR is a nationwide network of over 1000 transmitters broadcasting continuous weather updates directly from the nearest National Weather Service office. Each transmitter broadcasts official National Weather Service forecasts, weather watches and warnings, special statements, and current weather conditions for a specific area. Generally repeated every 4 to 10 minutes, the broadcast cycle is routinely updated every 1 to 3 hours (or more frequently if the weather dictates). During severe weather, routine weather broadcasts can be interrupted to highlight special warning messages concerning imminent threats to life and property.
Working with the Federal Communication Commission's Emergency Alert System (EAS), NWR is an "All Hazards" radio network, making it your single source of comprehensive weather and emergency information. In conjunction with federal, state, and local emergency management and other public officials, NWR can also broadcast information about non-weather hazards, such as earthquakes, chemical or oil spills, AMBER alerts, and 911 telephone outages. NWR is the only federally operated system that broadcasts weather and emergency warnings to the public.
Reception of NWR broadcasts depends on reliable signal reception. Typically a reliable signal can be received up to 40 miles from a station, assuming level terrain. However, NWR transmitters in hilly or urban areas may experience reduced signal reception due to signal blockage. Locally, the National Weather Service office in Wilmington, Ohio is responsible for 9 transmitters that serve its 52 counties spanning parts of Ohio, Indiana, and Kentucky. The seven frequencies in the VHF band (MHz) that NOAA Weather Radio broadcasts on include:
162.400
162.425
162.450
162.475
162.500
162.525
162.550
Weekly Test:
The National Weather Service in Wilmington, Ohio conducts weekly NOAA Weather Radio tests, allowing those with receivers to ensure their radio properly receives and is activated by the warning signal. The Routine Weekly Test is normally conducted every Wednesday morning between 11 AM and noon. If there is a threat of hazardous weather in the area on Wednesday morning, the test will be postponed until the next available good weather day during the same time frame. This test is an important way to check that your radio is programmed and functioning properly!
NOAA Weather Radio broadcasts heard across southeast Indiana, northern Kentucky, and central/southwest Ohio originate from the National Weather Service in Wilmington, Ohio. Each of our transmitters broadcasts official National Weather Service forecasts, weather watches and warnings, special statements, and current weather conditions for a specific area. Generally repeated every 4 to 10 minutes, the broadcast cycle is routinely updated every 1 to 3 hours (or more frequently if the weather dictates). During severe weather, routine broadcasts can be interrupted to highlight special warning messages concerning imminent threats to life and property.

With Specific Area Message Encoding (SAME) technology, life-saving messages broadcast on NWR can be targeted to a specific area. Many NWR products contain a special digital code with information about the type of event, the applicable geographic area for the event, and how long the event is valid. This allows receivers equipped with SAME technology to be programmed by the user to only alarm for weather and other emergency events in specific, desired counties, thereby eliminating unwanted alerts for areas that are not of concern to the listener. You will need the 6-digit SAME codes below for the counties you wish to program into your receiver.
SAME information can be heard audibly as 3 bursts of digital static (click to hear an example) at the beginning of the product transmission, followed by a 10-second broadcast of the 1050 Hz warning alarm tone (click to hear an example) which precedes the voice message part of the broadcast. Many NOAA Weather Radio receiver models can be set to a muted "standby" mode and will turn on when the alerting message is received. Depending on the receiver brand and model, the receiver will either be activated by the SAME code or the 1050 Hz warning alarm tone. Upon activation, some receiver models may have a flashing light or other visual attention signal. In any case, the 10-second 1050 Hertz warning alarm tone serves as an audible attention signal.
