6.7 NOAA WEATHER ALERT
In the event of extreme weather disturbances, such as storms and hurri-
canes, the NOAA (National Oceanic and Atmospheric Administration) sends
a weather alert accompanied by a 1050 Hz tone and subsequent weather
report on one of the NOAA weather channels. When the Weather Alert fea-
ture is enabled (see section 8.5 WX ALERT), the transceiver is capable of
receiving this alert if the following is performed:
1. Program NOAA weather channels into the transceiver’s memory for scan-
ning. Follow the same procedure as for regular channels under section
6.15.
2. Press the
[
SCAN
]
key once to start memory scanning or hold down the
[
SCAN
]
key during memory scanning to start priority scanning.
3. The programmed NOAA weather channels will be scanned along with
the regular-programmed channels. However, scanning will not stop on a
normal weather broadcast unless a NOAA alert is received.
4. When an alert is received on a NOAA weather channel, scanning will
stop and the transceiver will emit a loud beep to alert the user of a NOAA
broadcast.
5. Press the
[
WX
]
key to stop the alert tone and receive the weather report.
NOTE
If the
[
WX
]
key is not pressed the alert tone will be emitted for 5 minutes
and then the weather report will be received.
NOTE
The Weather Alert feature is also engaged while the transceiver is re-
ceiving on one of the NOAA weather channels.
6.8 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 marine VHF radios can detect. (Refer to Section 6.7
“NOAA WEATER ALERT” on how to use this feature.) This tone, when de-
tected, will produce a loud beep from the radio speaker to signal that a
weather alert is being broadcast.
In order to test this system, the NOAA broadcasts the 1050 Hz tone every
Wednesday, sometime between 11 AM and 1 PM.
