6.8 NOAA WEATHER CHANNELS AND ALERT
1. To receive a NOAA (National Oceanic and Atmospheric
Administration) weather broadcast, press and hold the
[
CLR
(
WX
)] key for one second. The transceiver changes
to the weather channel mode. This mode consists of a
preset memory bank containing the NOAA weather channels.
2. When the press and hold the [ CLR
(
WX
)] key, the transceiver will be set to
the last used NOAA weather channel. Press the [
] or [ ] key to change
to other weather channels.
3. To exit from the weather channel mode, press and hold the [ CLR
(
WX
)] key
for one second. The transceiver will revert to the channel you were using
prior to switching to the weather channel mode.
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 [ CLR
(
WX
)] key
to stop the beep tone and listen to the weather reports.
NOTE
By default the HX751 can alarm after a weather alert has been received
when a weather channel is selected and on the last selected Weather
channel during scanning, Dual Watch, Preset Scan and Preset Priority
Scanning. For additional settings, refer to Menu Mode Item “
13 ALt
(
WX
ALERT
)” on page 38.
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 Oceano-
graphic and Atmospheric Administration) broadcasts a 1050 Hz tone that some
VHF radios, including your
HX751 , can detect for “ Weather Alert ” purposes (re-
fer 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
HX751 , to signal that a Weather Alert Broadcast 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
HX751 periodically to confirm that the Weather Alert feature is
working, or for training crew members on how to configure the HX751 to re-
ceive the NOAA Weather Alerts.
