10.5 NOAA WEATHER ALERT TESTING
In the event of a major storm or other appreciable weather condition requir-
ing vessels at sea (or other bodies of water) to be notified, the NOAA (Na-
tional Oceanographic and Atmospheric Administration) broadcasts a 1050
Hz tone that some VHF radios, including your HX471S, can detect for
“Weather Alarm” purposes (refer to section 6.4.1 “NOAA WEATHER ALERT”
for a discussion of how to use this feature). The 1050 Hz tone, when de-
tected, will produce a loud beep in the speaker of the HX471S, to signal that
a Weather Alert Broadcast is being received.
In order to test this system, NOAA broadcasts the 1050 Hz tone every
Wednesday sometime between 11 AM and 1 PM local time. You may use
this opportunity to test your HX471S periodically to confirm that the Weather
Alert feature is working, or for training crew members on how to configure
the HX471S to receive the NOAA Weather Alerts.
