NOAA Weather Channels

VHF Marine Radio Protocols

NOAA Weather Channels And Alert

•

Monitoring the weather will probably be a frequent use of your radio. The National Oceanic and Atmospheric Administration (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 Wednesdaysometime 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.
