How NOAA Radios Work

NOAA radios operate on the Very High Frequency (VHF) band, specifically within the frequency range of 162.400 to 162.550 MHz. They receive signals transmitted by local NOAA Weather Radio stations, which are part of the National Weather Service (NWS) network. Here is a breakdown of how NOAA radios work:

  1. Receiving Signals: NOAA radios are equipped with an antenna that captures the VHF signals transmitted by the nearest Weather Radio station. The antenna converts the electromagnetic wave into an electrical signal, which is then processed by the radio’s internal circuitry.
  2. Tuning In: Once the signal is received, the NOAA radio allows users to tune in to the specific frequency of their local Weather Radio station. This can usually be done manually by adjusting the radio’s tuning dial or digitally via a menu interface.
  3. Broadcasting Weather Information: Once tuned in to the correct frequency, the NOAA radio will continuously receive broadcasts of weather information from the NWS. This includes weather forecasts, current conditions, and any emergency alerts or warnings issued by the NWS for the programmed area.
  4. Specific Area Message Encoding (SAME): NOAA radios equipped with SAME technology can receive and decode these specialized alerts. SAME allows for targeted alerts by programming the radio to receive alerts for a specific county or area. The radio checks the header of each alert message to determine if it matches the programmed location, and only activates the alert if there is a match.
  5. Alert Notifications: When a severe weather warning or emergency alert is received, NOAA radios with an automatic alerting feature will activate an audible and visual notification to alert the user. This ensures that users are immediately aware of any potential threats or hazardous conditions, even if the radio is turned off or on a different channel.
