(subaudible) CTCSS tone. Or if your friends have radios equipped with DCS (Digital Coded
Squelch) like your VX-8R has, try using that mode for silent monitoring of busy channels.
Selecting the Operating Band
In the factory default configuration, the VX-8R operates in the “Dual Receive” mode.
During Dual Receive operation, the “VFO-A” frequency will be displayed on the upper side
of the LCD, and the “VFO-B” frequency will be displayed on the lower side, with the
“Operating” band (the band on which transmission and band/frequency change are
possible) being indicated in large characters, and “Receive only” band being indicated in
small characters.
To switch the “Operating” band: press the [A] key momentarily to engage the “VFO-A”
frequency as the “Operating” band. Alternatively, press the [B] key momentarily to engage
the “Sub” band frequency as the “Operating” band, described previously.
Press and hold in the [A] or [B] key for 1/2 seconds to switch to Mono Band Operation with a
double-size display.
During Mono band operation, you may press the [F/W] key, then press the [A]/[B] key, to
change the display to show only large characters.
Selecting the Frequency Band
The VX-8R covers an incredibly wide frequency range, over which a number of different
operating modes are used. Therefore, the VX-8R’s frequency coverage has been divided
into different operating bands, each of which has its own pre-set channel steps and
operating modes. You can change the channel steps and operating modes later, if you like
(see page ??).
To Change Operating Bands
1. Press the [BAND] key repetitively. You will see the LCD indication move toward a higher
frequency band each time you press the [BAND] key. Indicates a Band Number
according to the receiving frequency on the display.
2. If you wish to move the operating band selection downward (toward lower frequencies),
press the [F/W] key first, then press the [BAND] key.
3. The VX-8R uses a dual VFO system (described previously). To switch TX/RX operation
from the “VFO-A” to the “VFO-B” instantly, press the [B] key momentarily. Pressing the
[A] key will return the VX-8R to the “VFO-A”. The frequency band bearing the “Large”
characters is the band on which transmission is possible; the band designated by
