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 Weater Aleart fea-
ture is enabled (see section 8.4 WEATER ALERT), the transceiver is ca-
pable 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
(
MEM
)] key once to start memory scanning or hold
down the [ SCAN
(
MEM
)] 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 Aleart feature is also engaged while the transceiver is
received on the one of the NOAA weather channel.
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 above section
“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.
