GENERAL DESCRIPTION
The VX-3R is a micro-miniature multiband FM transceiver with extensive receive frequency coverage, providing local-area two-way amateur communications along with unmatched monitoring capability.
The VX-3R’s incredibly small size allows you to take it anywhere - hiking, skiing, or while
walking around town - and its operating flexibility brings the user many avenues of operating enjoyment. Its incredibly tiny FNB-82LI Lithium-Ion Battery Pack provides up to 1.5
Watts of transmit power on VHF, and 1 Watt on UHF. In addition to the 144- and 430-MHz
transceiver operation, the VX-3R provides receive coverage of the AM (MF) broadcast
band, with the internal bar antenna, the FM broadcast bands, HF Shortwave Bands, VHF
and UHF TV bands, the VHF AM aircraft band, and a wide range of commercial and
public safety frequencies! The VX-3R internal antenna bar provides good AM broadcast
receive capabilities without having to use an external antenna.
Additional features include an Enhanced Paging and Code Squelch (EPCS), which 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 your transceiver only after
you enter your 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-3R to transmit your callsign and engage
your rig’s microphone, even if you are disabled and unable to press the PTT switch. 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.
We appreciate your purchase of the VX-3R, and encourage you to read this manual thoroughly, and learn about the many exciting features of your thrilling new Yaesu hand-held
transceiver!

VX-3R OPERATING MANUAL 5
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, as the
supplied antenna is very small and cannot be expected to provide high
performance at these frequencies.
To install the supplied antenna, hold the bottom end of the antenna and
screw it onto the mating connector on the transceiver until it is snug. Do
not over-tighten by use of extreme force.
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, to avoid excessive feedline
loss.
INSTALLATION OF FNB-82LI BATTERY PACK
The FNB-82LI is a high-performance Lithium-Ion battery providing high capacity in a
very compact package. Under normal use, the FNB-82LI may be used for approximately
300 charge cycles, after which operating time may be expected to decrease. If you have an
older battery that is displaying diminished capacity, you should replace the pack with a
new one. Installation of the battery is easy and quick:
1. Slide the Battery Cover
Latch to the Unlock position and then slide the Battery Cover toward the bottom to remove it.

VX-3R OPERATING MANUAL8
INTERFACE OF PACKET TNCS
The VX-3R may be used for Packet operation using the optional CT-91 microphone adapter
(available from 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 the transceiver’s volume
control, as with voice operation (Rotate the DIAL knob while pressing and holding the
[
VOL] key, do not forget to pull the DIAL knob to rotate the DIAL knob). The input level
to the VX-3R from the TNC should be adjusted at the TNC side. The optimum input audio
voltage is approximately 5 mV at 2000 Ohms.
Be sure to turn the transceiver and TNC off before connecting the cables, to prevent voltage spikes from possibly damaging your transceiver.
When you are operating in Packet Mode, switch the Receive Battery Saver OFF, as the
“sleep” cycle may “collide” with the beginning of an incoming Packet transmission,
causing your TNC not to receive the full data burst. See page 93 for details regarding
Battery Saver setup.
VX-3R OPERATING MANUAL 9
OPERATION
Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many features of the VX-3R. 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 orange POWER switch (on the left
side of the transceiver) for one second. Two beeps will be
heard when the switch has been held long enough, and the
current DC supply voltage will appear on the display for 2
seconds. If you are using the FNB-82LI Battery Pack, the
LitLit
small “
Lit” icon at the top of the display confirms that the
LitLit
Lithium-Ion Battery Pack has been detected. After this 2-second interval, the display
will resume its normal indication of the operating frequency.
3. To turn the VX-3R off, press and hold in the orange POWER switch again for one
second.
1) If you don’t hear the two “Beep” tones when the radio comes on, the Beeper
may have been disabled via the Set Mode Item 14: BP SEL. See page 19,
which tells you how to reactivate the Beeper.
2) You can change the Opening Message (DC supply voltage indication) to any desired
message (up to 6 characters) via Set Mode Item 59: OPN.MSG; see page 115 for details.
ADJUSTING THE VOLUME LEVEL
Pull the DIAL knob to unlock the mechanical dial lock, then
rotate the DIAL knob while pressing and holding the [VOL] key
to set the desired audio level. Clockwise rotation increases the
volume level.
1) You may set the Audio Output Level to the
Speaker, and the Earphone Output Level individu-
ally. The “SP” notation (which means Speaker) appears in the Memory Channel Number display slot while adjusting the Speaker Output Level. The “HP” notation
(which means Headphone) appears in the Memory Channel Number display slot while
adjusting the Earphone Output Level.
2) When pressing the [F/W] key followed by the [VOL] key, the DIAL knob function
changes to the Volume Level selection instead of the frequency control. In this case, the
“VOL” notation on the display blinks. Pressing the [F/W] key followed by the [VOL] key
again, the DIAL knob function returns to the frequency control. Furthermore, you may
change the [VOL] key function via Set Mode Item 92: VOL MD. See page 101 for details.
VX-3R OPERATING MANUAL10
OPERATION
SQUELCH ADJUSTMENT
The VX-3R’s Squelch system allows you to mute the background noise when no signal is
being received. The Squelch system make “standby” operation more pleasant, and 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, followed by the MONI switch on the left
side of the radio. This provides a “Short-cut” to Set Mode Item
SQ LVLSQ LVL
78:
SQ LVL.
SQ LVLSQ LVL
2. Now, rotate the DIAL knob to set the Squelch so that the background noise is just silenced (typically at a setting of about “
22
or “
2” for AM/FM, and “
22
AM Broadcast). This is the point of maximum sensitivity to weak
signals.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
3. When you are satisfied with the Squelch threshold setting, press the PTT switch momentarily to save the new setting and exit to normal operation.
1) The VX-3R can set the squelch threshold level on the AM mode, FM mode,
Wide FM mode, and AM Broadcast individually.
2) A special “S-meter Squelch” feature is provided on the VX-3R. This feature allows you to set the squelch so that only signals exceeding a certain S-meter level
will open the squelch. See page 22 for details.
3) 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-3R has, try using that mode for silent monitoring of busy
channels.

Operating Band
1) The VX-3R has an AM / FM broadcast radio. You can receive these bands
independently. See page 15 for details.
2) 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 100 for details.
VX-3R OPERATING MANUAL12
OPERATION
FREQUENCY NAVIGATION
The VX-3R will initially be operating in the “VFO” mode. This is a channelized system
which allows free tuning throughout the currently-selected operating band.
Two basic frequency navigation methods are available on the VX-3R:
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-3R 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-3R.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
2) SCANNING
From the VFO mode, press and hold in the [BAND] key for one
second, and while still holding in the [BAND] key, rotate the
DIAL knob to select the bandwidth for the VFO scanner. Release the [BAND] 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-3R will
then hold on that frequency according to the setting of the “RESUME” mode (Set Mode
Item 75:
SCN.RSMSCN.RSM
SCN.RSM). See page 54 for more details regarding Scan Operation.
SCN.RSMSCN.RSM
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-3R 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. This only stops the scan; it does
not cause transmission to occur.
Notice
The VX-3R may receive very strong signals on the Image frequency. 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.

VX-3R OPERATING MANUAL 13
OPERATION
TRANSMISSION
Once you have set up an appropriate frequency inside one of the 144 MHz or 430 MHz
Amateur bands on which the VX-3R can transmit, you’re ready to go on the air! 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 left-hand corner of
the speaker grille) in a normal voice level. The TX/BUSY
indicator 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 bar graph at the bottom of the
LCD. Full-scale deflection confirms “High
Power” operation, while deflection of two
bars indicates “Low Power” operation. Additionally, the “ ” icon will appear at the bottom of the display while operating on
the “Low Power” setting.
4. 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 [TXPO] key so that the
“ ” icon appears at the bottom of the display. And don’t
forget: always have an antenna connected when you transmit.
Transmission is possible only on the 144 MHz and 430 MHz bands.
1) The VX-3R is smart! You can set up Low power on 144 MHz band, while
leaving 430 MHz on High power, and the radio will remember the different
settings on both bands. 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 the Low power setting, you can press the [F/W] key,
before you press the PTT switch, to cause the VX-3R to transmit (temporarily) on High
power. After one transmission, the power level will revert to the previously-selected (Low
power) setting.

els set by the two squelch systems (Noise Squelch and S-meter Squelch).
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 S-meter Squelch (Set Mode Item 80) is set to “LVL 5,” the squelch
will only open on signals which are “S5” or stronger on the S-meter.
b) If the S-meter Squelch 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.

CTCSS OPERATION
Many repeater systems require that a very-low-frequency audio tone be superimposed on
your FM carrier in order to activate the repeater. This helps prevent false activation of the
repeater by radar or spurious signals from other transmitters. This tone system, called
“CTCSS” (Continuous Tone Coded Squelch System), is included in your VX-3R, and is
very easy to activate.
CTCSS setup involves two actions: setting the Tone Frequency and then setting of the Tone Mode. These actions are set up by using the [MODE] key or
