NOAA Weather Channels

Monitoring the weather will probably be a frequent use of your radio. NOAA provides

or three (3) hours, or as needed. The Coast Guard also announces weather and other

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 a loud tone from the speaker in the radio and will automatically switch to
the alerting weather channel so the alert broadcast can be heard.
NOAA Test Alert System
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 service to verify that this system is functioning properly.
These signals will be received in Marine or Weather Standby modes as described
below.
