Use WX ALERT to set your preferences for weather alert information. 

The NOAA provides several weather forecast channels on USA and Canadian channel banks. 
If severe weather such as storms or hurricanes are forecast, the NOAA broadcasts a weather 
alert on 1050 Hz.

The NOAA All Hazards Weather Radio Service (NWR) works in conjunction with the 
Emergency Alert System (EAS) to issue weather alerts for specific geographic areas or specific 
weather conditions. It uses a digital encoding system known as SAME (Specific Area Message 
Encoding) to broadcast these alerts. 

Each transmitter in the NOAA All Hazards Weather Radio Service (NWR) network is identified 
with a unique 6-digit SAME code. Each transmitter operates on one of 7 frequencies.

Note:  To activate a SAME alert, a SAME CODE (county ID) must be selected and turned ON 
(see section 4-8-2).

If TONE ALERT is ON and an alert tone of 1050 Hz is broadcast from the NOAA weather 
station, the weather alert is picked up automatically and the alarm sounds. Press any key to 
cancel the alarm and to hear the weather alert message.

to decode the special warning code transmissions.
