INTRODUCTION
FCC ID: K6620415X20 / IC:511B-20415X20
The Ultra Compact VX-8GR (2.4”W x 3.7”H x 1.1”D) is equipped with a GPS receiver and
thinner than the previous advanced model - It is packed with advanced technology and features, designed for outdoor operation. It is submersible (IPX5) and shockproof! The compact
case combines a rugged die-cast chassis with the clean, tough polycarbonate resin front panel.
Its shockproof versatility will allow you to operate the radio in the toughest environments.
The large High-resolution Dot Matrix LCD display provides clear, easy-to-read indication of
both “A” (Main band) and “B” (Sub band) frequencies, the operating mode, and S-meters for
both bands. When you engage the Spectrum Scope function, the high-resolution display will
indicate relative signal strengths of up to ±50 adjacent channels!
The built-in worldwide standard AX.25 Data TNC Modem permits uncomplicated APRS
operation. (Automatic Packet/Position Reporting System: APRS® is a registered trademark of
the APRS Software and Bob Bruninga, WB4APR.) The VX-8GR supports APRS
bps data communication on the “B” (Sub band) band only. You may communicate your location to other APRS
radio! You and others will be able to see your APRS
®
stations along with the position, speed and heading displayed on your
®
movement on the web! The VX-8GR
displays the received station’s positions, heading directions, messages, distances, icons (43
kinds), weather information, object, etc. With the list function you may automatically store and
recall up to 20 messages and the APRS
Unit can provide you with your real time APRS
®
data from up to 40 stations. The built-in GPS Receiver
®
data.
An Enhanced Paging and Code Squelch (EPCS) allows you to page a particular station and
only receive calls from that station. A security Password may be set, which will allow you to
turn on and operate the transceiver only after you enter the Password. A convenient key provides access to Vertex Standard’s WIRES™ (Wide-Coverage Internet Repeater Enhancement
System). The Emergency Automatic ID (EAI) function can automatically cause your VX-8GR
to transmit your callsign and engage your rig’s microphone, even if you are disabled and unable to press the PTT switch. Additional features include: transmit Time-Out Timer (TOT),
Automatic Power-Off (APO), and Automatic Repeater Shift (ARS). Yaesu’s exclusive ARTS
(Auto-Range Transponder System) which “beeps” the user when you move out of communications range with another ARTS™ equipped station. There is provision to reduce the TX deviation for use in areas of high channel congestion. The squelch circuit allows adjusting the squelch
to open at a programmable setting of the S-Meter, thus reducing guesswork in setting the
squelch threshold. Provides a DATA jack which enable to displaying the location data (Lat/
Lon) of the after-market GPS receiver, outputs the location data (Lat/Lon) of the built-in GPS
receiver unit and the Waypoint data of the received APRS beacon.
We appreciate your purchase of the VX-8GR, and encourage you to read this manual thor-
oughly, and learn about the many exciting features of your thrilling new Yaesu hand-held

VX-8GR OPERATING MANUAL15
OPERATION
FCC ID: K6620415X20 / IC:511B-20415X20
SELECTINGTHE FREQUENCY BAND
The VX-8GR covers an incred-
ibly wide frequency range, over
which a number of different operating modes are used. There-
fore, the VX-8GR’s frequency
coverage has been divided into
different operating bands. Each
band has its own preset channel
steps and operating modes. You can change the channel steps and operating modes later, if
you like (see page xx).
TO CHANGE OPERATING BANDS
1. Press the B key repeatedly. You will see the LCD
indication change to a higher frequency band each time
you press the B key. A Band Number according to
the receiving frequency is also displayed.
2. If you wish to move the operating band selection down-
ward (toward lower frequencies), press the f key
first, then press the B key.
3. The VX-8DR 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 briefly. Pressing
the a key will return TX/RX operation to “VFO-A”. The frequency band shown in
“Large” characters is the band on which transmission is possible; the band shown in
“Small” characters may only be used for reception.
4. Once you have selected the desired band, you may initiate manual tuning (or scanning). See the discussions on the next page.
If desired, you may omit (skip) one or more bands from the band selection
loop for faster recall of your favorite operating bands. See page xx for details.
VX-8GR OPERATING MANUAL16
OPERATION
FCC ID: K6620415X20 / IC:511B-20415X20
FREQUENCY NAVIGATION
The VX-8GR will initially be operating in the “VFO” mode, as just described. This is a fre-
quency step system which allows free tuning throughout the currently-selected operating band.
Three basic frequency navigation methods are available on the VX-8GR:
1) TUNING DIAL
Rotation of the DIAL knob allows tuning in the pre-pro-
grammed steps established for the current operating band.
Clockwise rotation of the DIAL knob causes the VX-8GR
to be tuned toward a higher frequency, while counter-clockwise rotation will lower the operating frequency.
If you press the f key briefly, then rotate the DIAL knob,
frequency steps of 1 MHz will be selected. This feature is
extremely useful for making rapid frequency excursions over the wide tuning range of the
VX-8GR.
2) DIRECT KEYPAD FREQUENCY ENTRY
The desired operating frequency may be entered directly from the keypad.
The operating mode will automatically be set once the new frequency is entered via the
keypad.
To enter a frequency from the keypad, just press the numbered digits on the keypad in the
proper sequence. There is no “Decimal point” key on the VX-8GR. However, there is a shortcut for frequencies ending in zero - press the c key after the last non-zero digit.
Examples:
To enter 146.520 MHz, press 146520
To enter 430.000MHz, press 43c

Dual Receive Notice
The VX-8GR may receive very strong signals on the Image frequency, and/or the
receiver sensitivity may be somewhat reduced by the combination of the “A-Band”
and “B-Band” frequencies while Dual Receive operation is engaged.
If you experience interference that you suspect may be coming in via an “Image”
path, you may calculate the possible frequencies using the formulas below. This
information may be used in the design of effective countermeasures such as traps,
etc.

TRANSMISSION
Once you have set up an appropriate frequency inside one of the dual amateur bands on
which the VX-8GR can transmit (144 MHz or 430 MHz), you’re ready to transmit. These
are the most basic steps; more advanced aspects of transmitter operation will be discussed
later.
1. To transmit, press the PTT switch, and speak into the
front panel microphone (located in the upper right-hand
corner of the speaker grille) in a normal voice level.
The LED of the “A” or “B” which is designated the
“Main” band will glow red during transmission.
2. To return to the receive mode, release the PTT switch.
3. During transmission, the relative power level will be
indicated on the LCD. Additionally, the “L1”, “L2”, “L3”,
or “HI” icon will appear at the left side of the PO meter,
corresponding with the “Power” Level setting.
1) If you’re just talking to friends in the immediate
area, you’ll get much longer battery life by switching to Low Power opera-
tion. To do this, press the f key, then press the d key so that the “Low
Power” icon appears at the bottom of the display. And don’t forget:

CHANGINGTHE TRANSMITTER POWER LEVEL
You can select between a total of four transmitter power levels on your VX-8GR. The
exact power output will vary somewhat, depending on the voltage supplied to the trans-
ceiver. With the standard FNB-101LI Battery Pack and external DC source, the power
output levels available are: “L1”, “L2”, “L3”, or “HI”
To change the power level:
1. The default setting for the power output is “High;” in
this configuration, the display shows the “HI” icon.
Pressing the f key, followed by the d key, causes
the power level “L1”, “L2”, or “L3” to appear.
2. Press the f key, followed by the d key (repeat-
edly, if necessary) to make the “HI” icon appear and
restore “High Power” operation.

1) The VX-8GR is smart! You can set up Low power on one band (like UHF),
while leaving VHF on High power , and the radio will remember the dif ferent
settings on each band. And when
you store memories, you can store High and
Low power settings separately in each
memory, so you don’t waste battery power
when using very close-in repeaters!

the squelch threshold which was set by step 4 above will blink.
2) The receiver’s squelch will open based on the higher of the levels set by the
Noise Squelch or the S-meter Squelch system.
For example:
a) If the Noise Squelch (SQL control) is set so that signals at a level of “S-3” will open
the squelch, but the SQL S-meter (Set Mode Item 93) is set to “LEVEL 5,” the squelch
will only open on signals which are “S5” or stronger on the S-meter.
b) If the SQL S-meter is set to “S3,” but the Noise Squelch is set to a high level which
will only pass signals which are Full Scale on the S-meter, the squelch will only open on
signals which are Full Scale on the S-meter. In this case, the Noise Squelch overrides
the action of the S-meter Squelch.

REPEATER OPERATION
FCC ID: K6620415X20 / IC:511B-20415X20
GENERAL
Repeater stations, usually located on mountaintops or other high locations, provide a dramatic extension of the communication range for low-powered hand-held or mobile trans-
ceivers. The VX-8GR includes a number of features, which make repeater operation simple
and enjoyable.
REPEATER SHIFTS
Your VX-8DR has been configured, at the factory, for the repeater shifts customary in
your country. For the 144 MHz band, this usually will be 600 kHz, while the 430 MHz
shift will be 1.6 MHz, 7.6 MHz, or 5 MHz (USA version).
Depending on the part of the band in which you are operating, the repeater shift may be
either downward (
and one of these icons will appear at
the bottom of the LCD when repeater
shifts have been enabled.
) or upward (),
AUTOMATIC REPEATER SHIFT(ARS
)
The VX-8GR provides a convenient Automatic Repeater Shift feature, which causes the
appropriate repeater shift to be automatically applied whenever you tune into the designated repeater sub-bands in your country. These sub-bands are shown below.
If the ARS feature does not appear to be working, you may have accidentally disabled it.
To re-enable ARS:
