Weather Band Operation

What is the NOAA Weather Radio/Weatheradio Canada?

NOAA (National Oceanic and Atmospheric Administration) is a nationwide system that 
broadcasts local weather emergency information 24 hours a day via the National Weather 
Service (NWS) network. The U.S. network has more than 530 stations covering the 50 states 
as well as the adjacent costal waters, Puerto Rico, the U.S. Virgin Islands and the U.S. Pacific 
Territories. Each local area has its own transmitting station and there are a total of seven 
broadcasting frequencies used. A similar system is available in Canada under the Weatheradio 
Canada service administered by Environment Canada.

Tuning to Weatherband

Press and hold

 the 

BAND/WB

 button (15) to access the Weatherband. The indication "WB" 

will appear on the display panel, along with the current number and channel indication: "WB-1", 
“WB-2", "WB-3", "WB-4", "WB-5", "WB-6" or "WB-7". The seven frequencies are shown in the 
following table:

The above table also shows which preset button will access the frequency. Note that one 
frequency cannot be accessed using a preset button. The frequency can only be reached 
using the tuning controls.

Use the 

TUNE/SEEK >>| 

or 

|<< 

buttons (19, 18) or the preset buttons to tune to each of the 

seven channels until you find the weatherband station broadcasting in your area.

How many stations can I expect to receive?

Since the broadcasts are local weather and information, the transmission power is usually very 
low (much less than standard AM or FM stations) so you will usually receive only one station 
unless you are on the edge of two or more broadcast signals. The most you will receive will be 
two or three, and that is rare. 

Is it possible I won't receive any stations?

Depending on where you are located, there is a possibility you will receive only a very weak 
signal or none at all. Also, similar to AM and FM signals, weatherband signals are subject to 
surrounding conditions, weather, obstructions of the signal by hills or mountains, etc.
