• When an NWS office broadcasts a warning, watch or non-weather emergency, it also 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, county(s) affected, and message expiration time.
• A programmed NWR SAME receiver will 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.

The following messages are always alerted on a NWR Transmitter if they apply to any part of its coverage area:

• Green: 0dBuV to 18dBuV: picking up a signal is possible but unreliable
• Red: Less than 0dBuV: Unlikely to receive a signal
