Availability of accessories may vary. Some accessories are supplied as standard per local 
requirements, while others may be unavailable in some regions. Consult your Yaesu Dealer 
for details regarding these and any newly-available options. Connection of any 
non-Yaesu-approved accessory, should it cause damage, may void the Limited Warranty on 
this apparatus. 
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-8R 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-8R may be operated on frequencies higher than the 50 MHz band 
while the Extender Element is still attached onto the Antenna Base. 
Notes: 
•  Never transmit without having an antenna connected. 
•  When installing the supplied antenna, never hold the upper part of the antenna while 
screwing it onto the mating connector on 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 not lose the antenna cap when removing it from the Base Antenna. 
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. If you have an old

battery pack which is displaying capacity which has become diminished, you should replace 
the pack with a new one. 
1.  Install the FNB-101LI as shown in the illustration. 
2.  Close the Battery Pack Latch on the bottom of the radio. 
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 or E-DC-6 DC Adapter (with its cigarette lighter plug) 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 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 transmission in an emergency, but power 
output will only be selectable 1 W and 50 mW. 
To Install Alkaline Batteries into the FBA-39 
1.  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. 
2.  Open the Battery Pack Latch on the bottom of the radio. 
3.  Install the FBA-39 as shown in the illustration, with the [+] side facing the bottom of the 
transceiver. 
4.  Close the Battery Pack Latch on the bottom of the radio. 
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-8R 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. 
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. 
(2) Continuous signal reception 
The current battery voltage can be displayed manually on the LCD, by following the 
instructions on page ??. 
Battery capacity may be reduced during extremely cold weather operation. Keeping the 
radio inside your parka may help preserve the full charge capacity. 
AC Operation Using NC-86B/C (Receiving only) 
The VX-8R may be operated from your house current by use of the supplied NC-86B/C 
Battery Charger. The NC-86B/C should only be used for reception, because it is not capable 
of supplying sufficient current to support transmission. 
To use the NC-86B/C, turn the transceiver off, then plug the miniature connector of the 
Battery Charger into the EXT DC jack on the side of the radio. Now plug the Battery Charger 
into the wall outlet. You may now turn on the transceiver. 
Interface of Packet TNC 
The VX-8R may be used for Packet operation, using the optional CT-131 microphone 
adapter (availablefrom your Yaesu dealer) for easy interconnection to commonly-available 
connectors wired to your TNC. You may also build your own cable using a four-conductor 
miniature phone plug, per the diagram below. 
The audio level from the receiver to the TNC may be adjusted by using the VOLUME knob, 
as with voice operation. The input level to the VX-8R from the TNC should be adjusted at the 
TNC side; the optimum input voltage is approximately 5 mV at 2000 Ohms. 
Be sure to turn the transceiver and TNC off before connecting the cables, so as to prevent 
voltage spikes from possibly damaging your transceiver. 
Operation 
Note: Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many features of the 
VX-8R. 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 the battery 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, and the opening 
message will appear on the display, then frequency display will appear. After another 
two seconds, the receive-mode Battery Saver function will become active, unless you 
have disabled it (see page ??). 
3.  To turn the VX-8R off, press and hold in the [PWR] switch again for 2 seconds. 
Note: 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 ??, which tells you how to reactivate the 
Beeper. 
Adjusting the Volume Level 
Rotate the DIAL knob while pressing and holding the [VOL] key to set the desired audio level. 
Clockwise rotation increases the volume level. 
The Volume level may be set on the “Main” and “Sub” bands separately. 
Squelch Adjustment 
The VX-8R’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 [F/W] key, then press the [MONI/T-CALL] key on the left side of the radio. 
This provides a “Short-cut” to Menu Item 96: SQL LEVEL. 
2.  Now, rotate the DIAL knob to set the background noise is just silenced (typically at a 
setting of about “3” or “4” on the scale); this is point of maximum sensitivity to weak 
signals. 
3.  When you are satisfied with the Squelch threshold setting, press the PTT key 
momentarily 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 ?? 
for details. 
Note 1: The Squelch level may be set on the “Main” and “Sub” bands separately. 
Note 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

(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

“Small” characters may only be used for reception. 
4.  Once you have selected the desired band, you may initiate manual tuning (or scanning) 
per the discussions on the next page. 
Note 1: The SW Band and Information Band reception is only possible on the “VFO-A”. 
Note 2: The VX-8R has an AM/FM Broadband radio. You can receive these bands 
independently. See page ?? for details. 
Note 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 ?? for details. 
Frequency Navigation 
The VX-8R will initially be operating in the “VFO” mode, as just described. This is a 
channelized system which allows free tuning throughout the currently-selected operating 
band. 
Three basic frequency navigation methods are available on the VX-8R: 
1) Tuning Dial 
Rotation of the DIAL knob allows tuning in the pre-programmed steps established for the 
current operating band. Clockwise rotation of the DIAL knob causes the VX-8R to be tuned 
toward a higher frequency, while counter-clockwise rotation will lower the operating 
frequency. 
If you press the [F/W] key momentarily, 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-8R. 
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-8R, 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 [V/M] key after the last non-zero 
digit. 
Examples: 
To enter 146.520 MHz, press [1] Æ [4] Æ [6] Æ [5] Æ [2] Æ [0]

3) Scanning 
From the VFO mode, press and hold in either the [UP] or [DOWN] key for one second to 
initiate upward or downward scanning, respectively, and will stop when it receives a signal 
strong enough to break through the Squelch threshold. The VX-8R will then hold on that 
frequency according to the setting of the “RESUME” mode (Menu Item 89: SCAN RESUME). 
See page ?? for details. 
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-8R 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 momentarily to cancel the scanning. 
Transmission 
Once you have set up an appropriate frequency inside one of the three (or four) Amateur 
bands on which the VX-8R 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 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. 
Note 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 [F/W] key, then press the 
[Internet] 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. 
Note 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:

To change the power level: 
1.  The default setting for the power output is “High;” in this configuration, the display 
shows “HI” icon. Pressing the [F/W] key, followed by the [Internet] key, causes the 
power level “L1”, “L2”, or “L3” to appear. 
2.  Press the [F/W] key, followed by the [Internet] key (repeatedly, if necessary) to make the 
“HI” icon appear and restore “High Power” operation. 
Note 1: The VX-8R 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! 
Note 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-8R to transmit (temporarily) on High power. After 
one transmission, the power level will revert to the previously-selected Low power setting. 
AM and FM Broadcast Reception 
The VX-8R includes provision for reception of AM and FM broadcasts. FM broadcast 
reception, utilizes a wide-bandwidth filter and stereo decoder which provides excellent 
fidelity. 
1.  Press the [A] key momentarily to engage the “VFO-A” as the “Operating” band. 
2.  Press the [F/W] key, then press the [0(RADIO)] key to enter the Broadcast Reception 
mode. 
3.  Press the [BAND(SC-M BND DW)] key to toggle the receiving band between “AM 
broadcast” and “FM broadcast”. 
The AM broadcast coverage is 510 to 1790 kHz and utilizes AM mode. The Band 
Number changes to “A” (which means AM) and an Operating Mode icon changes to 
“AM”. 
The FM broadcast coverage is 76.00 to 107.90 MHz and utilizes Wide-FM mode. The 
Band Number changes to “F” (which means FM) and an Operating Mode icon changes 
to “WFM”. 
4.  Rotate the DIAL knob to select the desired station. 
5.  To exit to normal operation, press the [F/W] key followed by the [0(RADIO)] key. 
Note: The AM and FM Broadcast reception is only possible on the “VFO-A”. 
Antenna Selection 
The VX-8R allows you to select the antenna for the Broadcast Reception.
