ECEPTION
The FT-2800M 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
Broadcast 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.
Severe Weather Alert Feature
In the event of extreme weather disturbances, such as storms and hurricanes, 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. You
may enable the this feature via Menu “32 W ALT,” if desired. See page 55 for details.
If NOAA issues a severe weather alert, the FT-2800M will issue a warbling pair of audio
tones. Press the PTT button momentarily to disable the alarm, and the Severe Weather mes-
sage will now be audible from the speaker.
If you have the Severe Weather Alert feature engaged, and you engage scanning of the
Weather Channel bank by pressing and holding in the [UP] or [DWN] key, the radio will not
stop on a “busy” weather broadcast channel until the 1050 Hz Alert Tone is received from a
NOAA weather broadcast station! You may, however, select any of the ten weather broad-
cast channels manually by rotating the main tuning dial, or by pressing the [UP] or [DWN]
key momentarily, step by step, to choose the desired station.
When scanning the band or the “regular” memories, with the Severe Weather Alert feature
engaged, you will notice that the FT-2800M 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.
