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-1 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 Vertex Standard’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),
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 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

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 NC-86 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.

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 NC-86, E-DC-5B, or E-DC-6 may safely be connected 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.

OPERATION
SQUELCH ADJUSTMENT
The VX-8DR/DEs 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. 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.
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 maxi-
mum sensitivity 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.

)
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 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/DEs 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 uses a dual VFO system (described pre-
viously). 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.

CHANGING THE CHANNEL STEPS
The VX-8DR/DEs frequency synthesizer provides the option of utilizing tuning steps of 5,
6.25, 8.33, 9, 10, 12.5, 15, 20, 25, 50, 100, and 200 kHz per step. The VX-8DR/D E is set up
at the factory with different default steps for each operating band which are probably satis-
factory for most operation. However, if you need to change the channel step increments,
the procedure to do so is very easy.
1. Press the key, then press the key on the left side of the radio. This provides a
“Short-cut” to Set Mode Item 96: STEP FREQUENCY.
2. Rotate the DIAL knob to select the desired step size.
3. Press the PTT switch to save the new setting and return to
normal operation.
1) 9 kHz steps are available only when receiving on the BC band.
2) 8.33 kHz steps are available only when receiving on the Air band.
3) While operating on the BC band, you may only select channel steps of 9
kHz or 10 kHz; the other step selections are disabled.
4) 5 kHz steps are not available for use on 250 - 300 MHz, nor above 580 MHz.
CHANGING THE RECEIVING MODE
The VX-8DR/DE provides for automatic mode changing
when the radio is tuned to different operating frequencies.
However, should an unusual receiving situation arise in
which you need to change to a different receiving mode,
just press the key. The receiving modes available are:
AUTO: The receive mode is automatically set accord-
ing to the default values for the selected fre-
quency range
NFM: Narrow-bandwidth FM (used for voice communication)
WFM: Wide-bandwidth FM (used for high-fidelity broadcasting)
AM: Amplitude Modulation
1) The “WFM” mode cannot be selected on the “B-Band”.
2) Unless you have a compelling reason to do so, leave the Automatic Mode
Selection feature on in order to save time and trouble when changing bands.
If you make a mode change for a particular frequency or station, you can always store
that one channel into memory, as the mode setting will be memorized along with the
frequency information.

REPEATER OPERATION
VX-8DR/DE OPERATING MANUAL36
DCS OPERATION
Another form of tone access control is Digital Code Squelch, or DCS. It is a newer, more
advanced tone system which generally provides more immunity from false paging than
does CTCSS. The DCS Encoder/Decoder is built into your VX-8DR/DE, and operation is
very similar to that just described for CTCSS. Your repeater system may be configured for
DCS. The DCS Squelch may be quite useful in Simplex operation if your friends use
transceivers equipped with this advanced feature.
Note: Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS
and that you select a DCS code.
1. Press the key, then press the key. This provides a
“Short-cut” to Set Mode Item 95: SQL TYPE.
2. Rotate the DIAL knob until “DCS” appears on the display;
this activates the DCS Encoder/Decoder.
3. Press the key to save the new setting and exit to nor-
mal operation.
4. Press the key, then press the key. This provides a
“Short-cut” to Set Mode Item 26: DCS CODE.
5. Rotate the DIAL knob to select the desired DCS Code (a three-digit number). Ask the
repeater owner/operator if you don’t know DCS Code; if you are working simplex,
just set up the DCS Code to be the same as that used by your friends.
6. When you have made your selection, press the key to save the new settings and
exit to normal operation.
Remember that the DCS is an
Encode/Decode system, so your
receiver will remain muted until
a matching DCS code is received on an in-
coming transmission. Switch the DCS off
when you’re just tuning around the band!

VX-8DR/DE OPERATING MANUAL 37
DCS CODE INVERSION
The DCS system was first introduced in the commercial LMR (Land Mobile Radio) ser-
vice, where it is now in widespread use. DCS is sometime referred to by its different
proprietary names, such as DPL
®
(Digital Private Line
®
, a registered trademark of Motorola,
Inc.).
DCS uses a codeword consisting of a 23-bit frame, transmitted (sub audible) at a data rate
of 134.4 bps (bit/sec). Occasionally, signal inversion can result in the complement of a
code being sent or received. This prevents the receiver’s squelch from opening with DCS
enabled, as the decoded bit sequence would not match that selected for operation.
Typical situations that might cause inversion to occur are:
Connection of an external receiver preamplifier.
Operating through a repeater.
Connection of an external linear amplifier.
Note that code inversion does not mean that any of the above listed equipment is defective!
In certain amplifier configurations, the output signal (phase) is inverted from the input. Small
signal or power amplifiers having an odd number (1, 3, 5, etc.) of amplification stages may
result in inversion of a transmitted or received DCS code. While under most circumstances
this should not occur (amplifier designs and industry standards take this into account), if you
find that your receiver squelch does not open when both you and the other station are using a
common DCS code, you or the other station (but not both) can try the following:
1. Press and hold the key for one second to enter the Set Mode.
2. Rotate the DIAL knob to select Set Mode Item 27: DCS
INVERSION.
3. Press the key briefly to enable adjustment of this Set
Mode Item.
4. Rotate the DIAL knob to select one of the following modes:
RX-NORMAL, TX-NORMAL:
Receive and transmit the Normal DCS Tone.
RX-INVERT, TX-NORMAL:
Receive the Inverted DCS Tone and transmit the Normal DCS Tone.
RX-BOTH, TX-NORMAL:
Receive both Normal and Inverted DCS Tones and transmit the Normal DCS
Tone.
RX-NORMAL, TX-INVERT:
Receive the Normal DCS Tone and transmit the Inverted DCS Tone.

5. When you have made your selection, press the PTT switch, to save the new settings
and exit to normal operation.
This is different from the usual method of restoring normal operation, and it applies only
to the configuration of the CTCSS/DCS frequencies. Remember to restore the default
setting “R-N.T-N” (Receive and transmit the Normal DCS Tone) when done.

DCS OPERATION
VX-8DR/DE OPERATING MANUAL 39
TONE SEARCH SCANNING
In operating situations where you don’t know the CTCSS or DCS tone being used by
another station, you can command the radio to listen to the incoming signal and scan in
search of the tone being used. Two things must be remembered in this regard:
You must be sure that your repeater uses the same tone type (CTCSS vs. DCS).
Some repeaters do not pass the CTCSS tone; you may have to listen to the station
transmitting on the repeater uplink (input) frequency in order to allow Tone Search
Scanning to work.
To scan for the tone in use:
1. Set the radio up for either CTCSS or DCS Decoder operation (see the previous dis-
cussion). In the case of CTCSS,
TSQ” will appear on the display;
in the case of DCS, “DCS” will ap-
pear on the display.
2. Press the key, then press the
key to recall the Set Mode
Item 99: TONE FREQUENCY
when CTCSS is selected, or Menu
Item 26: DCS CODE during DCS operation.
3. Press the key to enable adjustment of the selected Set Mode Item.
4. Press and hold in the key, the “TONE SEARCH” notation will appear, release the
key to start scanning for the incoming CTCSS or DCS tone/code.
5. When the radio detects the correct tone or code, it will halt on that tone/code, and
audio will be allowed to pass. Press the key to lock in that tone/code, then press
the key to exit to normal operation.
If the Tone Scan feature does not detect a tone or code, it will continue to
scan indefinitely. When this happens, it may be that the other station is not
sending any tone. You can press the PTT switch to halt the scan at any time.
You can also press the key during Tone Scanning to listen to the (muted) signal from
the other station. When you release the key, Tone Scanning will resume after about a
second.
Tone Scanning works either in the VFO or Memory modes.

available characters.
Example 2: Press the key repeatedly to toggle among
the seven available characters associated with
that key: t u v 8 T U V
6. Press the key to move to the next character, if needed.
7. Repeat steps 5 and 6 to program the remaining letters, num-
bers, or symbols of the desired label. A total of 16 charac-
ters may be used in the creation of a label.
8. Press and hold the key for two seconds to delete all
data after the cursor that may have been previously stored.
9. If you make a mistake, press the key to backspace the cursor, then re-enter the
correct letter, number, or symbol.

MEMORY OFFSET TUNING
Once you have recalled a particular memory channel, you may easily tune off that chan-
nel, as though you were in the “VFO” mode.
1. With the VX-8DR/DE in the Memory Recall (“MR”) mode, select the desired memory
channel.
2. Now press the key, then press key. The “MR” in-
dicator will be replaced by one which says “TUN” (“Memory
Tuning”).
3. Rotate the DIAL, as desired, to tune to a new frequency.
The synthesizer steps selected for VFO operation on the current band will be the steps
used during Memory Tuning.
4. If you wish to return to the original memory frequency, press key briefly. The
TUN” indicator will be replaced by “MR.”
5. If you wish to store a new frequency set during Memory Tuning, just press and hold
in the key for one second, per normal memory storage procedure. The micropro-
cessor will automatically set itself to the next-available clear memory location, and
you then press the key again, briefly to lock in the new frequency.
If you want to replace the original memory contents with the new frequency
settings, be sure to rotate the DIAL to the original memory channel number!

MASKING MEMORIES
There may be situations where you want to “Mask” memories so they are not visible
during memory selection or scanning. For example, several memories used only in a city
you visit infrequently may be stored, then “Masked” until you visit that city, at which time
you can “Unmask” them for normal use (except for Memory Channel “1”).
1. Press the key, if needed, to enter the Memory Recall (“MR”) mode.
2. Press and hold in the key for 1/2 second, then rotate
the DIAL to select the memory channel to be “Masked”
from view.
3. Press the key. The confirmation message (MR MASK?)
will appear on the display. Press the key once more, the
display will revert to memory channel #1. If you rotate the
DIAL to the location you just “Masked,” you will observe
that it is now invisible.
4. To Unmask the hidden memory, repeat the above procedure: press and hold in the
key for 1/2 second, rotate the DIAL to select the masked memory’s number, then
press the key to restore the memory channel’s data.
Watch out! You can manually store data over a “Masked” memory, deleting
previous data, if you’re not careful. Use the “next available memory” stor-
age technique to avoid over-writing a masked memory.
VX-8DR/DE OPERATING MANUAL 53
MEMORY BANK OPERATION
The large number of memories available in the VX-8DR/DE could be difficult to utilize
without some means of organizing them. Fortunately, the VX-8DR/DE includes provi-
sion for dividing the memories into as many as 24 Memory Banks, so you can categorize
the memories in a manner convenient to you. You may enter and exit the “Memory Bank”
mode by a single press of the key, as we shall see below.
ASSIGNING MEMORIES TO A MEMORY BANK
1. Recall the memory channel to be assigned to a Memory
Bank.
2. Press and hold in the key for 1/2 second, then rotate the
DIAL knob to select the Memory Bank number where you
want to include this channel (Memory Bank numbers are
found before memory channel “1”). The “ ” icon will ap-
pear at the upper left of the Memory Bank number if some
channels have already been assigned to that Memory Bank
number. (If no channels are assigned to the Memory Bank, the “ ” icon appears on
the left of the Memory Bank number).
3. Press the key briefly.
4. At this point, the memory
channel data is copied into
the Memory Bank.
1) You may assign
one memory chan-
nel into several
Memory Banks.
2) The PMS memory channels
(L1/U1 through L50/U50) may not be assigned to a Memory Bank.
MEMORY BANK RECALL
1. Press the key, if needed, to enter the MR mode.
2. Press the key to activate the “Memory Bank” mode.
The “MR” indicator will be replaced by one of the Memory
Bank numbers (“B 1” through “B24”).
3. Press the key, and then press the key,
then rotate the DIAL knob to select the desired
Memory Bank.
4. Press the key. Now, as you rotate the DIAL
knob to select memories, you will observe that you
can only select memory channels in the current Memory Bank.

Once memory channel programming has been completed, you may place the radio in a
“Memory Only” mode, whereby VFO operation is impossible. This may be particularly
useful during public-service events where a number of operators may be using the radio
for the first time, and ultimate simplicity of channel selection is desired.
To place the radio into the Memory Only mode, turn the radio off. Now press and hold in
the key while turning the radio on.
To return to normal operation, repeat the above power-on procedure.
