NOAA Weather Channels and Alert

Monitoring the weather will probably be a frequent use of your radio. NOAA provides
continuous, around-the-clock broadcasts of the latest weather information. Taped
weather messages run every four (4) to six (6) minutes and are revised every two
(2) or three (3) hours, or as needed. The Coast Guard also announces weather and
other safety warnings on Channel 16 and DSC Channel 70. Smart boaters keep an
eye on safety and an ear to the radio — and never let the weather catch them
unaware.
NOAA Emergency Weather Alert
In the event of a major storm or other weather condition requiring vessels at sea
or on other bodies of water to be notified, NOAA broadcasts a 1050 Hz tone that
receivers such as your CobraMarine VHF radio can detect and warn you of a weather
alert condition. When the Weather Alert mode on your radio is On, this signal will
produce the weather alert alarm tone from the speaker and a "weather alert"
message on the LCD to signal that a weather alert is being broadcast.
The radio will automatically switch to Weather Radio mode.
Test
To test this system, NOAA broadcasts the 1050 Hz signal every Wednesday
sometime between 11 a.m. and 1 p.m. in each local time zone. Any receiver that can
detect the weather alert tone may use this feature to verify that this feature is
functioning properly.
