INTRODUCTION
The Ultra Compact VX-8DR (2.4”W x 3.7”H x 0.9”D) is thinner than the previous advanced model - It is packed with advanced technology and features, designed 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, are also available with the VX-8DR. The optional Bluetooth® Unit BU-1 makes it possible to operate Hands-free with the optional waterproof Bluetooth® headsets 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 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 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® data from up to 40 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 provides access to Vertex Standard's WIRES™ (Wide-Coverage Internet Repeater Enhancement System). The Emergency Automatic ID (EAI) function can automatically cause your VX-8DR 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 completely independent FM/AM broadcast receiver and an internal 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, and encourage you to read this manual thoroughly, and learn about the many exciting features of your thrilling new Yaesu hand-held transceiver!

INSTALLATION OF ACCESSORIES
ANTENNA INSTALLATION
The supplied antenna provides good results over the entire frequency range of the transceiver. 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 Element” (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 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 may be operated on frequencies 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- |
Figure 1 |
|
tic Cap out with a small tool or screwdriver. |

INSTALLATION OF ACCESSORIES
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 approximately 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. |
INSTALL |
|
The VX-8DR battery must be correctly installed, to BATTERY PACK RELEASE KNOB maintain the waterproof integrity.
REMOVE
If the battery has never been used, or its charge is depleted, it may be charged by connecting the NC-86B/C Battery Charger, as shown in the illustration, to the EXT DC jack. 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.

INSTALLATION OF ACCESSORIES
INSTALLATION OF FBA-39 ALKALINE BATTERY CASE (OPTION)
The optional FBA-39 Battery Case allows receive monitoring using three “AA” size Alkaline 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), 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.
Figure 1 |
Figure 2 |
The FBA-39 does not provide connections for charging, since Alkaline cells cannot be re-charged. Therefore, the NC-86B/C, E-DC-5B, or E-DC-6 may safely be connected to the EXT DC jack when the FBA-39 is installed.
Notes:
The FBA-39 is designed for use only with AA-type Alkaline cells.
If you do not use the VX-8DR 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 transceiver.

VX-8DR OPERATING MANUAL |
OPERATION
Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many features of the VX-8DR. 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 become active, unless you have disabled it (see page 125).
3. To turn the VX-8DR 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 increases 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
SQUELCH ADJUSTMENT
The VX-8DR’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 Broadcast) 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. 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, try using that mode for silent monitoring of busy channels.
24-HOUR CLOCK
The VX-8DR 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 OPERATING MANUAL |
OPERATION
SELECTING THE OPERATING BAND
In the factory default configuration, the VX-8DR 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 possible) 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 described previously.
Press and hold in the or key for 1/2 seconds to switch to Mono Band Operation. During Mono band operation, 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.

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 scanning). 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 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 OPERATING MANUAL |
OPERATION
FREQUENCY NAVIGATION
The VX-8DR 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:
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 to be tuned toward a higher frequency, while counter-clock- wise 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.
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, 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 |

|
|
|
|
|
|

|
|
|

FREQUENCY NAVIGATION
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 scanner. 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 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 is scanning. The scanning direction will be reversed. To revert to scanning toward a higher frequency once more, rotate the DIAL knob one click clockwise.
Press the PTT switch briefly to cancel the scanning. See page 60 for more details regarding 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.
Dual Receive Notice
The VX-8DR 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.

“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 OPERATING MANUAL |
OPERATION
TRANSMISSION
Once you have set up an appropriate frequency inside one of the three (or four) Amateur bands on which the VX-8DR 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 operation. 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-8R. The exact power output will vary somewhat, depending on the voltage supplied to the transceiver. 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 (repeatedly, if necessary) to make the “HI” icon appear and restore “High Power” operation.

OPERATION
TRANSMISSION
1) The VX-8DR 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, |
