The FT-2900R includes a unique feature which allows reception of weather broadcasts in
the 160-MHz frequency range. Ten standard Weather Broadcast channels are pre-loaded
into a special memory bank.
To listen to a Weather Broadcast Channel:
1. Press the Microphone’s [
P4
] button to recall the Weather
Broadcast channels.
2. Turn the DIAL knob to select the desired Weather Broad-
cast channel.
3. If you wish to check the other channels for activity
by scanning, just press the Microphone’s PTT
switch.
4. To exit to normal operation, press the [ P4
] button
again. Operation will return to the VFO or Memory
channel you were operating on before you began Weather Broadcast operation.
The [P4] key, one of the programmable keys, is assigned (default setting) as the
“WX Broadcast” one-touch access key. Please note that if you change/assign an-
other function to the [P4] key, one-touch access to the WX channel will be unavailable.
Severe Weather Alert Feature
In the event of extreme weather disturbances, such as storms and hurricanes, NOAA (the
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. You
may enable this feature via Menu Item “57 WX ALT,” if desired. See page 49 for details.
When scanning the band or the “regular” memories, with the Severe Weather Alert feature
engaged, you will notice that the
FT-2900R will break over to the Weather Channel bank
every five seconds, performing a quick scan of those channels in search for the 1050 Hz
alert tone. If the alert tone is received, operation will lock on the weather broadcast station
issuing the alert; otherwise, the radio will revert to the VFO or memory scan session in
progress without interruption.
When the alert tone is received, press the PTT button momentarily to disable the alarm, and
the Severe Weather message will now be audible from the speaker.
