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 coastal 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: 162.400MHz (CH2), 162.425MHz (CH4), 162.450MHz (CH5),
162.475MHz (CH3), 162.500MHz (CH6), 162.525MHz (CH7) and 162.550MHz
(CH1).
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.
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, weather band
signals are subject to surrounding conditions, weather, obstructions of the signal by
hills or mountains, etc. If no NOAA signals are found/received, the tuner will scan all
seven NOAA frequencies every 30 seconds.
When you select the weather band, LCD will display the current channel frequency.
Press the |<<or >>|buttons (6, 8) to tune to each of the seven channels until you find
the weather band station broadcasting in your area.
The Weather Alert function adds an additional level of user safety by automatically
switching from any of the available function modes to weather band for a minimum of
120 seconds if a NOAA warning tone (1050 Hz) is received/detected. If no additional
warning tone is received for
120 seconds, the unit will switch back to the last known function mode. See "System
Menu" on page 5 to learn how to turn the WB Alert feature on.
