6.8.1 NOAA WEATHER ALERT
In the event of extreme weather disturbances such as storms and hurricanes,
NOAA sends a “weather alert” consisting of a 1050 Hz tone, followed by weather
reports on the weather channels.
When a “weather alert” is received on a weather channel, the transceiver emits
a beep tone and the TX/BUSY indicator blinks white. Press the
[
WX
]
key to
stop the beep tone and listen to the weather reports.
NOTE

6.8.2 NOAA WEATHER ALERT TESTING
In the event of a major storm or other appreciable weather condition requiring
vessels at sea (or other bodies of water) to be notified, the NOAA (National
Oceanographic and Atmospheric Administration) broadcasts a 1050 Hz tone
that some VHF radios, including your HX750S, can detect for “Weather Alarm”
purposes (refer to section “6.8.1 NOAA WEATHER ALERT” for a discussion
of how to use this feature). The 1050 Hz tone, when detected, will produce a
loud beep in the speaker of the HX750S, to signal that a Weather Alert Broad-
cast is being received.
In order to test this system, NOAA broadcasts the 1050 Hz tone every Wednes-
day sometime between 11 AM and 1 PM local time. You may use this opportu-
nity to test your HX750S periodically to confirm that the Weather Alert feature
is working, or for training crew members on how to configure the HX750S to
receive the NOAA Weather Alerts.
