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
Notice
Caution
Warning
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.
