How Same Codes Work
- When an NWS office broadcasts an urgent audio message (warning, watch, or non-weather emergency) it also creates and broadcasts a digital SAME code (that may be heard as a very brief static burst, depending on the characteristics of the receiver). This SAME code contains the type of message and the county(s) affected.
- An appropriately programmed NWR SAME receiver will then turn on for that message, with the listener hearing the 1050 Hz warning alarm tone as an attention signal, followed by the broadcast message.
- At the end of the broadcast message, listeners will hear a brief digital end-of-message static burst followed by a resumption of the NWR broadcast cycle.
