Understanding Digital Weather Alert
The weather service precedes each weather alert with a digitally-

encoded SAME (Specific Area Message Encoding) signal, then 

a 1050 Hz tone. When your local weather station broadcasts 

a weather alert signal, the CB radio sounds an alert tone and 

displays a message showing the alert level.

A (Watch)

Watch alert 

10 seconds

WCH (Watch)

W (Warning) 

TOR (Tornado) 

SVR (Severe)

Warning alert 

10 seconds

WRN (Warning)

S (Statement) 

RWT (Test)

Statement alert 

10 seconds

ADV (Advisory)

Notes:
•  The CB radio does not display the actual location referenced 

by SAME messages. It uses only the message portion of the 

SAME signal.

•  If severe weather threatens, do not wait for an alert tone; 

tune to the weather broadcast and monitor the weather 

information.

•  If a weather signal ends, the CB radio beeps three times 

(when the key tone is turned on) and only when the weather 

signal ends the first time, then 

WX flashes to indicate there is 

no signal.
