What is the NOAA Weather Radio?

NOAA  is  a  nationwide  system  that  broadcasts  local  weather  emergency  information  24  hours  a  day.  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).

How many stations can I expect to receive?

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

Is it possible I won't receive any stations?

Depending on location, it's possible to receive 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, the tuner will scan all seven NOAA frequencies every 30 seconds.

NOAA Weather Alert

The Weather Alert function adds an additional level of user safety by automatically switching from the current function mode to 
weather band mode for a minimum of 60 seconds if a NOAA warning tone (1050 Hz) is received. If no additional warning tone 
is received for 60 seconds, the unit will switch back to the last known function mode.
