Vertex Standard VX-8R ユーザーズマニュアル

The AF-Dual Operation allows you to monitor two desired amateur band frequencies
while also receiving an AM or FM broadcast station (Triple Watch functions!). When a
signal is received in the amateur band, the amateur band audio is output instead of the AM
or FM Broadcast station audio. When the amateur band signal drops, the AF-Dual Opera-
tion is resumed as determined by the user settings in the below procedures. Furthermore,
you may transmit on the “Main” band amateur frequency by pressing the PTT switch at
anytime. The “Main” band is selected by pressing the 

/

 key as usual.

1. Set the VX-8R to the desired amateur band frequencies by the VFO or Memory chan-

nel selections on both “A-Band” and “B-Band”.

2. Select the “Main” Band you wish to use for transmit by pressing the 

/

 key.

3. Press the

 key to activate the

AF Dual operation.

4. Press the 

 key to toggle the receiver between “AM

broadcast” and “FM broadcast”.

5. Rotate the DIAL knob to tune the desired Broadcast station.
6. When a signal is received in the amateur band, the amateur band audio is output to the

speaker. The AM or FM Broadcast station will no longer be heard. Two seconds after
the amateur band signal drops, the AF-Dual Operation is resumed and the AM or FM
Broadcast station will be heard from the speaker, while the amateur band frequencies
are monitored. You may change the default resume time (two seconds) via Set Mode
