VX-8DR/DE OPERATING MANUAL 1
The Ultra Compact VX-8DR/DE (2.4” W x 3.7” H x 0.9” D (60 W x 95 H x 24.2 D)) is thinner
than the previous advanced model - It is packed with advanced technology and features, de-
signed for outdoor operation. It is submersible 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 Bluetooth® capabilities, already known and utilized among users and enthusiasts of the
FTM-10R/SR/E/SE, are also available with the VX-8DR/DE. The optional Bluetooth
®
Unit
BU-2 makes it possible to operate Hands-free with the optional waterproof Bluetooth® head-
sets BH-1A (Stereo) or BH-2A (monaural).
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-8DR/DE supports APRS® 1200/
9600 bps data communication on the B band only. You may communicate your location to
other APRS
®
stations along with the position, speed and heading displayed on your radio! You
and others will be able to see your APRS® movement on the web! The VX-8DR/DE 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 30
messages and the APRS
®
data from up to 50 stations. The optional GPS Antenna Unit FGPS-
2 can provide you with your real time APRS® data. You may also send the information without
the FGPS-2 if you manually input your data in advance.
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 pro-
vides access to Yaesu’s WIRES™ (Wide-Coverage Internet Repeater Enhancement System).
The Emergency Automatic ID (EAI) function can automatically cause your VX-8DR/DE 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), Auto-
matic 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 communica-
tions range with another ARTS™ equipped station. There is provision to reduce the TX devia-
tion 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 completely independent FM/AM broadcast receiver and an inter-
nal bar antenna for better AM broadcast reception. Listen to FM broadcasts in stereo with your
stereo headset/earphone!
We appreciate your purchase of the VX-8DR/DE, and encourage you to read this manual thor-
oughly, and learn about the many exciting features of your thrilling new Yaesu hand-held
transceiver!

VX-8DR/DE OPERATING MANUAL8
Figure 1
Figure 2
ANTENNA INSTALLATION
The supplied antenna provides good results over the entire frequency range of the trans-
ceiver. However, for enhanced base station medium-wave and shortwave reception, you
may wish to connect an external (outside) antenna. The supplied antenna consists of two
sections: the “Base Antenna” (used for operation above 50 MHz), and the “Extender Ele-
ment” (used for monitoring of frequencies below 50 MHz).
TO INSTALL THE SUPPLIED ANTENNA
Hold the bottom end of the antenna, then screw it onto the
mating connector on the transceiver until it is snug. Do not
over-tighten by use of extreme force.
When operating the VX-8DR/DE on the 50 MHz band and
lower frequencies, disconnect the antenna cap from the base
antenna, then screw the Extender Element onto the Antenna
Base. Of course, the VX-8DR/DE may be operated on fre-
quencies higher than the 50 MHz band while the Extender
Element is still attached to the Antenna Base.
Notes:
Never transmit without having an antenna connected.
Carefully turn the supplied antenna onto the SMA jack.
Never twist the upper part of the antenna while screwing
it onto the mating connector of the transceiver.
If using an external antenna for transmission, ensure that
the SWR presented to the transceiver is 1.5:1 or lower.
Take care, do not lose the antenna cap when removing it
from the Base Antenna.
BELT CLIP INSTALLATION
Install the supplied Belt Clip to the FNB-101LI
Battery Pack using the supplied two screws
(Figure 1). Use only the screws included with
the Belt Clip to mount the Belt Clip to the back
of the Battery Pack!
If you do not need the Belt Clip, install the sup-
plied Plastic Cap to the Battery Pack (Figure
2). If you install the belt clip later, push the Plas-
tic Cap out with a small tool or screwdriver.
INSTALLATION OF ACCESSORIES
VX-8DR/DE OPERATING MANUAL 9
INSTALLATION OF FNB-101LI BATTERY PACK
The FNB-101LI is a high-performance Lithium-Ion battery providing high capacity in a
very compact package. Under normal use, the FNB-101LI may be used for approxi-
mately 300 charge cycles, after which operating time may be expected to decrease. An old
battery pack, which is displaying diminished capacity should be replaced with a new one.
To install the FNB-101LI Battery Pack, carefully mate the
battery’s three alignment tabs with their corresponding align-
ment slots on the transceiver bottom case, then gently press
the top side of the Battery Pack until it locks in place with a
“click”.
To remove the Battery Pack, turn the transceiver off and
remove any protective cases. Press the Battery Pack Release
Knobs downward to unlock the latch, then remove the Bat-
tery Pack from the transceiver.
1) The VX-8DR/DE battery must be correctly in-
stalled, to maintain the waterproof integrity.
2) Always use the FNB-101LI or optional FNB-
102LI Lithium-Ion Battery Pack.
3) Battery Pack shall not be exposed to excessive heat such
as sunshine, fire, or the like.
4) Risk of explosion if battery is replaced by an incorrect
type. Dispose of used batteries according to the instructions..
If the battery has never been used, or its charge is depleted, it may be charged by connect-
ing the PA-44 or SAD-11B Battery Charger, as shown in the illustration, to the EXT DC
jack.
In the USA/EXP market, if only 12 ~ 16 Volt DC power is available, the optional E-DC-
5B DC Adapter (with its cigarette lighter plug) or E-DC-6 DC Cable may also be used for
charging the battery, as shown in the illustration.

While the battery is being charged, the display will indicate “CHARGING” and the key
will glow red. The S-meter will deflect according to the charging status. When charging is
finished, the display will change to indicate “COMPLETE” and the key will glow green.
In the USA Version, the key is not lit when charging or when charging is complete.
When the charge is complete, the transceiver turns off after 3 minutes.
1) Turn the radio off while charging the battery.
2) Perform the battery charging where the ambient temperature range +41
°F to +95 °F (+5 °C to +35 °C). Charge out of this range could cause damege
to the battery pack.
3) Use only the Yaesu Musen Co., Ltd. model PA-44B/C/U or SAD-11B Battery Charger.
BATTERY LIFE INFORMATION
When the battery charge is almost depleted, a “Low Voltage” indicator will appear on the
display. When this icon appears, it is recommended that you charge the battery soon.
(1) TX 6 sec., RX 6 sec. and Squelched 48 sec (continuous operating cycle).
(2) Continuous signal reception.
The present battery voltage can be displayed manually on the LCD, by following the
instructions on page 119.
Battery capacity may be reduced during extremely cold weather. Keeping the radio inside
your parka may help preserve the full charge capacity.

INSTALLATION OF FBA-39 ALKALINE BATTERY CASE (OPTION
)
The optional FBA-39 Battery Case allows receive monitoring using three “AA” size Al-
kaline batteries. Alkaline batteries can also be used for low power transmission in an
emergency. The power output will only be selectable 1 W/50 mW (for 50/144/430 MHz
FM) or 500 mW/50 mW (for 222 MHz FM: USA version), or 1 W fixed (for 50 MHz
AM).
TO INSTALL ALKALINE BATTERIES INTO THE FBA-39
1. Lift up the lower right corner of the rubber cover, and then open the cover (Figure 1).
2. Referring to Figure 2, slide the batteries into the FBA-39 as shown in the illustration,
with the Negative
[–]
side of the batteries touching the spring connections inside the
FBA-39.
3. Close the rubber cover.
4. Install the FBA-39 in the transceiver in the same manner as the FNB-101LI.
INSTALLATION OF ACCESSORIES
The FBA-39 does not provide connections for charging, since Alkaline cells cannot be
re-charged. Therefore, the PA-44, SAD-11B, E-DC-5B, or E-DC-6 may safely be con-
nected to the EXT DC jack when the FBA-39 is installed (E-DC-5B and E-DC-6 are
usable only in the USA/EXP market).
Notes:
The FBA-39 is designed for use only with AA-type Alkaline cells.
If you do not use the VX-8DR/DE for a long time, remove the Alkaline batteries from
the FBA-39, as battery leakage could cause damage to the FBA-39 and/or the trans-
ceiver.

INTERFACE OF PACKET TNCS
The VX-8DR/DE may be used for Packet operation, using the optional CT-M11 MIC/SP
Connection Cable (available from your Yaesu dealer) for easy interconnection to com-
monly-available connectors wired to your TNC.
The audio level from the receiver to the TNC may be adjusted by rotating the DIAL knob
while pressing and holding the key, as with voice operation. The input level to the
VX-8DR/DE from the TNC should be adjusted at the TNC side; the optimum input volt-
age is approximately 5 mV at 2000 Ohms.
Be sure to turn the transceiver and TNC off before connecting the cables, to prevent volt-
age spikes from damaging your transceiver.

VX-8DR/DE OPERATING MANUAL 13
Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many
features of the VX-8DR/DE. I know you’re anxious to get on the air, but I
encourage you to read the “Operation” section of this manual as thoroughly
as possible, so you’ll get the most out of this fantastic new transceiver. Now. . .let’s get
operating!
SWITCHING POWER ON AND OFF
1. Be sure the battery pack is installed, and that it is fully charged. Connect the antenna
to the top panel ANTENNA jack.
2. Press and hold in the (PWR) switch (on the right
side of the front panel) for 2 seconds. Two beeps will be
heard when the switch has been held long enough. The
opening message will appear briefly on the display, then
the frequency display will appear. After another two sec-
onds, the receive-mode Battery Saver function will be-
come active, unless you have disabled it (see page 125).
3. To turn the VX-8DR/DE off, press and hold in the (PWR) switch again for 2
seconds.
If you don’t hear the two “Beep” tones when the radio comes on, the Beeper
may have been disabled via the Menu system. See page 27, which tells you
how to reactivate the Beeper.
ADJUSTING THE VOLUME LEVEL
Rotate the DIAL knob while pressing and holding the
key to set the desired audio level. Clockwise rotation in-
creases the volume level.
1) The Volume level may be set on the
“A-Band” and “B-Band” separately.
2) You may set the Audio Output Level to the
Speaker, and the Earphone Output Level individually. The
“SP VOLUME” notation appears in the S- & PO meter area while adjusting the Speaker
Output Level. The “HP VOLUME” notation appears in the S- & PO meter area while
adjusting the Earphone Output Level.
3) Pressing the key followed by the key, the DIAL knob function changes to
the Volume Level adjustment instead of the frequency control. In this case, the “Volume
Level Indicator” on the display blinks. Pressing the key followed by the key
again, returns the DIAL knob function to the frequency control. You may also change
the key function via Set Mode Item 107: VOLUME MODE. See page 133 for de-
tails.
OPERATION
VX-8DR/DE OPERATING MANUAL14
OPERATION
SQUELCH ADJUSTMENT
The VX-8DR/DE’s Squelch system allows you to mute the background noise when no
signal is being received. Not only does the Squelch system make “standby” operation
more pleasant, it also significantly reduces battery current consumption.
The Squelch system may be adjusted independently for the FM and Wide-FM (FM Broad-
cast) modes.
1. On the VX-8DR, Press the key, then press the
key on the left side of the radio. This provides a “Short-
cut” to Set Mode Item 92: SQL LEVEL.
On the VX-8DE, press and hold the key for one
second to enter the Set Mode, rotate the DIAL knob to
select Set Mode Item 92: SQL LEVEL, then press the
key briefly to enable adjustment of this Set Mode
Item.
2. Now, rotate the DIAL knob to the point where the back-
ground noise is just silenced (typically at a setting of about
“3” or “4” on the scale); this is the point of maximum sen-
sitivity to weak signals.
3. When you are satisfied with the Squelch threshold setting, press the PTT key briefly
to save the new setting and exit to normal operation.
4. You may also adjust the Squelch setting by using the “Set” (Menu) mode. See page
157 for details.
1) The Squelch level may be set on the “Main” and “Sub” bands separately.
2) If you’re operating in an area of high RF pollution, you may need to
consider “Tone Squelch” operation using the built-in CTCSS Decoder. This
feature will keep your radio quiet until a call is received from a station sending a carrier
which contains a matching (sub audible) CTCSS tone. Or if your friends have radios
equipped with DCS (Digital Coded Squelch) like your VX-8DR/DE, try using that mode
for silent monitoring of busy channels.
24-HOUR CLOCK
The VX-8DR/DE has a 24-hour clock with a calendar which covers all dates from
January 1, 2000 through December 31, 2099. Set the clock according to the “Clock
Set” column on page 120.
VX-8DR/DE OPERATING MANUAL 15
SELECTING THE OPERATING BAND
In the factory default configuration, the VX-8DR/DE operates in the “Dual Receive”
mode.
During Dual Receive operation, the “A-Band” frequency will be displayed on the upper
part of the LCD, and the “B-Band” frequency will be displayed on the lower part. The
“Operating” band (the band on which transmission and band/frequency changes are pos-
sible) is shown in large characters, and “Receive only” band is shown in small characters.
Press the key briefly to engage the “A-Band” fre-
quency as the “Operating” band. Alternatively, press the
key briefly to engage the “B-Band” frequency, as de-
scribed previously.
Press and hold in the or key for 1/2 seconds to
switch to Mono Band Operation. During Mono band op-
eration, you may change the display between “double-size
character” and “large character” by pressing the /
key.
When monitoring the receive audio with stereo earphones, the audio from
the “A-Band” is only heard in the left ear, and the audio from the “B-Band”
is only heard in the right ear.
OPERATION
VX-8DR/DE OPERATING MANUAL16
OPERATION
SELECTING THE FREQUENCY BAND
The VX-8DR/DE covers an incredibly wide frequency range, over which a number of
different operating modes are used. Therefore, the VX-8DR/DE’s frequency coverage has
been divided into different
operating bands. Each
band has its own preset
channel steps and operat-
ing modes. You can
change the channel steps
and operating modes later,
if you like (see page 29).
TO CHANGE OPERATING BANDS
1. Press the key repeatedly. You will see the LCD
indication change to a higher frequency band each time
you press the 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 key
first, then press the key.
3. The VX-8DR/DE uses a dual VFO system (described
previously). To switch TX/RX operation from the “VFO-A” to the “VFO-B” instantly,
press the key briefly. Pressing the 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 scan-
ning). See the discussions on the next page.
1) SW Band and Information Band reception is only possible on the “VFO-A”.
2) The VX-8DR/DE has an AM/FM Broadcast band radio. You can receive
these bands independently. See page 22 for details.
3) 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 132 for details.

VX-8DR/DE OPERATING MANUAL 17
FREQUENCY NAVIGATION
The VX-8DR/DE will initially be operating in the “VFO” mode, as just described. This is a
frequency step system which allows free tuning throughout the currently-selected operating
band.
Three basic frequency navigation methods are available on the VX-8DR/DE:
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-8DR/
DE to be tuned toward a higher frequency, while counter-
clockwise rotation will lower the operating frequency.
If you press the 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-8DR/DE.
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-8DR/DE, so if the frequency is
below 100 MHz (e.g. 15.150 MHz), any required leading zeroes must be entered. However,
there is a short-cut for frequencies ending in zero - press the key after the last non-zero
digit.
Examples:
To enter 146.520 MHz, press
To enter 15.255 MHz, press
To enter 1.250 MHz (1250 kHz), press
To enter 0.950 MHz (950 kHz), press
To enter 430.000MHz, press
OPERATION
VX-8DR/DE OPERATING MANUAL18
3) SCANNING
From the VFO mode, press and hold in the key for
one second, and while still holding in the key, rotate
the DIAL knob to select the bandwidth for the VFO scan-
ner. Release the key to begin scanning toward a higher
frequency. The scanner will stop when it receives a signal
strong enough to break through the Squelch threshold. The
VX-8DR/DE will then hold on that frequency according to
the setting of the “RESUME” mode (Menu Item 83: SCAN
RESUME).
If you wish to reverse the direction of the scan (i.e. toward a lower frequency, instead of a
higher frequency), just rotate the DIAL knob one click in the counter-clockwise direction
while the VX-8DR/DE is scanning. The scanning direction will be reversed. To revert to
scanning toward a higher frequency once more, rotate the DIAL knob one click clock-
wise.
Press the PTT switch briefly to cancel the scanning. See page 60 for more details regard-
ing Scan Operation.
You may initiate upward or downward scanning by pressing and holding
either or key for one second, respectively. In this case, the scanner
scans the bandwidth that was previously selected.
OPERATION
FREQUENCY NAVIGATION
Dual Receive Notice
The VX-8DR/DE 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.
9.8304 MHz x n 11.7 MHz x n (n is an integer: 1, 2, 3, …)
4.9152 MHz x n 6.1440 MHz x n
“A-Band” Freq. = (“B-Band” Freq. ± 46.35 MHz) x n
“B-Band” Freq. = (“A-Band” Freq. ± 47.25 MHz) x n (@ “A-Band” = NFM)
“B-Band” Freq. = (“A-Band” Freq. ± 45.8 MHz) x n (@ “A-Band” = WFM)
VX-8DR/DE OPERATING MANUAL 19
TRANSMISSION
Once you have set up an appropriate frequency inside one of the three (or four) Amateur
bands on which the VX-8DR/DE can transmit (50 MHz, 144 MHz, or 430 MHz, plus 222
MHz on the USA version), 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 lower right-hand
corner of the speaker grille) in a normal voice level.
The LED of the or 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 key, then press the key so that the “Low
Power” icon appears at the bottom of the display. And don’t forget: always have an
antenna connected when you transmit.
2) Transmission is not possible on “Sub” band and any operating bands other than the
50 MHz, 144 MHz, 222 MHz (USA version), and 430 MHz bands on the “Main” band.
CHANGING THE TRANSMITTER POWER LEVEL
You can select between a total of four transmitter power levels on your VX-8DR/DE. 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 key, followed by the key, causes
the power level “L1”, “L2”, or “L3” to appear.
2. Press the key, followed by the key (repeat-
edly, if necessary) to make the “HI” icon appear and
restore “High Power” operation.
OPERATION
VX-8DR/DE OPERATING MANUAL20
OPERATION
1) The VX-8DR/DE 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
different 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!
2) When you are operating on one of the Low power settings, you can press the key,
then press the PTT switch,
to cause the VX-8DR/DE to
transmit (temporarily) on
High power. After one trans-
mission, the power level will
revert to the previously-se-
lected Low power setting.
VOX OPERATION
The VOX system provides automatic transmit/receive switching based on voice input to the
microphone. With the VOX system enabled, you do not need to press the PTT switch in order
to transmit, and it is not necessary to use a VOX headset in order to utilize VOX operation.
1. Press and hold in the key for one second to enter the Set mode.
2. Rotate the DIAL knob to select the Set Mode Item 108:
VOX.
3. Press the key briefly to enable adjustment of this Set
Mode Item.
4. Rotate the DIAL knob to select the desired VOX Gain level
(“HIGH” or “LOW”).
5. When you have made your choice, press the PTT switch to
save the new setting and return to normal operation.
6. Without pressing the PTT switch, speak into the VX-8DR/
DE microphone in a normal voice level. When you start
speaking, the transmitter should be activated automatically.
When you finish speaking, the transceiver should return to
the receive mode (after a short delay).
To cancel VOX and return to PTT operation, just repeat the above procedures, selecting
“OFF” in step 4 above.
When the VOX system is activated, the “ ” icon will appear on the display.
The VOX is activated by the VX-8DR/DE. The optional MH-74A7A Speaker/
Microphone is ignored.
