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, then screw it onto the mating connector
4
Vertex Standard Co., Ltd.

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 old battery pack which is displaying capacity which has
become diminished, you should replace the pack with a new one.
Installation of the battery is easy and quick:
Slide the Battery Cover Latch to the Unlock position, then slide the Battery Cover toward the bottom to
remove it.
Install the FNB-82LI into the Battery Compartment.
Replace the Battery Cover, then slide the Battery Cover Latch into the “Lock” position.
Important Note: There is a small stud in the Battery Compartment of the VX-3R. This stud is a switch for the
battery detection. Please be careful not to break this stud while battery changing.
Battery Charging
If the battery has never been used, or its charge is depleted, it may be charged by connecting the NC-85
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-21 DC Adapter (with its cigarette lighter plug) may also be used for charging the battery.
While the battery is being charged, the display will indicate “CHGING” and the TX/BUSY indicator will glow
red. The S-meter will deflect according to the charging status.
When charging is finished, the display will change to indicate “CHGFUL” and the TX/BUSY indicator will
glow green.
The NC-85 is only designed for the charging of the VX-3R’s battery, and is not suitable for other purposes.
Please be advised that the NC-85 may contribute noise to TV and radio reception in the immediate vicinity,
so we do not recommend its use adjacent to such devices.
Important Note: 1) Perform the battery charging where the ambient temperature range is 41 °F to 95 °F
(+5 °C to +35 °C). Charge out of this range could cause damage to the battery pack.

2) When charge is not finished even if it passes for three hours, appears “CHGERR” in the display and
finishes the charging forcibly. In this case, there is the possibility that battery becomes deterioration. Please
contact your yaesu dealer.
3) If you do not use the VX-3R for a long time, remove the FNB-82LI Lithium-Ion battery pack from the
VX-3R, as battery leakage could cause damage to the VX-3R and FNB-82LI.
4) When a FNB-82LI Lithium-Ion battery pack is not used for a long time, please remove it from the
transceiver. Also, while in storage, the charge will drain slightly over time and the battery should be
recharged 50% each six months.
Installation of FBA-37 Alkaline Battery Case (option)
The optional FBA-37 Battery Case allows operation of the VX-3R using three “AA” size alkaline batteries.
When installing batteries, insert the (–) end first, then press in the (+) end so the battery snaps into place.
Always replace all three batteries at the same time, paying attention to the polarity indicated inside the
case.
The FBA-37 must not be used with rechargeable cells. The FBA-37 does not contain the thermal and
over-current protection circuits (provided in the FNB-82LI Lithium-Ion Battery Pack) required when utilizing
Ni-Cd and Ni-MH cells.
Note that the power output and battery life will be much shorter when using Alkaline AA cells. They should
be considered an emergency backup power source only, for this reason.
The VX-3R is smart, when the FBA-37 Battery Pack is installed to the VX-3R, a charge circuit does not
work even if the external DC power supply is connected to the EXT DC IN Jack.
Important Note: 1) The FBA-37 is designed for use only with AA-type Alkaline cells (LR6).
2) If you do not use the VX-3R for a long time, remove the alkaline batteries from the FBA-37, as battery
leakage could cause damage to the VX-3R and FBA-37.
Battery Life Information
When the battery charge is almost depleted, a “Battery” icon will appear on the display. When the “Battery”
icon appears, it is recommended that you charge the battery soon.

Battery capacity may be reduced during extremely cold weather operation. Keeping the radio inside your
parka may help preserve the full charge capacity.
Interface of Packet TNCs
The VX-3R may be used for Packet operation, using the optional CT-91 microphone adapter (available
from your Y aesu dealer) for easy interconnection to commonly-available connectors wired to your TNC. Y ou
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 (rotate
the DIAL knob while press and holding the [VOL] key, do not forget to pull the DIAL knob to rotate the DIAL
knob), as with voice operation. The input level to the VX-3R 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.
When you are operating on Packet, 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 ?? for details regarding Battery Saver setup.
Operation
R.F. says: 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 indicated on the display for 2 seconds; if you are using the FNB-82LI Battery Pack, the small “Lit”
icon at the top of the display confirms that the 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.
R.F. says: 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 ??, 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 57: OPN.MSG; see page ?? for details.
Adjusting the Volume Level
Pull the DIAL knob to unlock the mechanical dial lo ck, then rota te the DIAL knob while pressing and holding
the [VOL] key to set the desired audio level. Clockwise rotation increases the volume level.
R.F. Says: 1) You may set the audio level by the Speaker Output Level and the Earphone Output Level
individually . The “SP” not ation (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 press the [F/W] key followed by the [VOL] key, the DIAL knob function change to the Volume Level
selection instead of the frequency control. In this case, the “VOL” notation on the display is blinked. Press
the [F/W] key followed by the [VOL] key again, the DIAL knob function returns to the frequency control.
Squelch Adjustment
The VX-3R’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] switch on the left side of the radio. This provides a
“Short-cut” to Set Mode Item 78: SQ 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 “1” or “2” for AM/FM, and “2” or “3” for Wide-FM/FM Broadcast/AM Broadcast); this is
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.
R.F. Says: 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 ?? 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.

VX-3R Operating Manual
Selecting the Operating Band
The VX-3R covers an incredibly wide frequency range, over which a number of different operating modes
are used. Therefore, the VX-3R’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 ??).
Operating Bands
BAND BAND NUMBER FREQUENCY RANGE
SW Band 1 1.8 - 30 MHz
50 MHz Ham Band 2 30 - 59 MHz
Air Band 3 108 - 137 MHz
144 MHz Ham Band 4 137 - 174 MHz
VHF-TV Band 5 174 - 222 MHz
Information Band 1 6 222 - 420 MHz
430 MHz Ham Band 7 420 - 470 MHz
UHF-TV Band 8 470 - 800 MHz
Information Band 2 9 803 - 999 MHz
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 with the receiving frequency in the Memory Channel Number
Display Slot of 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. Once you have selected the desired band, you may initiate manual tuning (or scanning) per the
discussion in the next chapter.
R.F. Says: 1) The VX-3R has an AM broadcasting band and an FM broadcast band with these bands and
can receive it independently. See page ?? for details.
2) You may skip (omit) the several bands from the band selection loop for fast recalling the operating band,
if you desired. See page ?? for details.
Frequency Navigation
The VX-3R will initially be operating in the “VFO” mode, a channelized system which allows free tuning
9
Vertex Standard Co., Ltd.
FCC ID: K6620285X20
IC ID: 511B-20285X20
VX-3R Operating Manual
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 ex treme ly use ful for making rap id freque ncy ex cursio ns ov er the wide tu ning 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 rotate the DIAL knob while
holding in the [BAND] key to select the bandwidth for the VFO scanner, then 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.RSM). See page ?? for details regarding Scan Operation.
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.
3.579545 MHz x n
11.7 MHz x n (n is an integer: 1, 2, 3, …..)
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 “LOW” icon will appear at the bottom of the display while operating

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 “LOW” 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.
R.F. Says: 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, when 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.

Changing the Channel Steps
The VX-3R’s synthesizer provides the option of utilizing channel steps of 5/8.33/9/10/12.5/15/20/25/50/100
kHz per step (optional values are different by a operating band), as well as an automatic step selection
based on the current operating frequency (“AUTO”), any number of which may be important to your
operating requirements. The VX-3R is set up at the factory in the “AUTO” configuration, which probably is
satisfactory for most operation. However, if you need to change the channel step increments, the procedure

VX-3R Operating Manual
Changing the Receiving Mode
The VX-3R 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 other
receiving mode, just press the [MODE] key. The receiving modes available are:
AUTO: Automatic mode setting per default values for the selected frequency range.
FM: Narrow-bandwidth FM (used for voice communication)
W-FM: Wide-bandwidth FM (used for high-fidelity broadcasting)
AM: Amplitude Modulation
R.F. Says: Unless you have a compelling reason to do so, leave the Automatic Mode Selection feature on
so as to save time and trouble when changing bands. If you make a mode change for a particular channel
or station, you can always store that one channel into memory, as the mode setting will be memorized
along with the frequency information.
S-meter Squelch
A special S-meter Squelch feature is provided on this radio. This feature allows you to set the squelch so
that only signals exceeding a certain S-meter level will open the squelch.
To set up the S-meter squelch circuit for operation, use the following procedure:
1. Press and hold in the [TXPO] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 80: SQSMTR.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
3. Press the [TXPO] key momentarily to enable adjustment of this Item.
4. Rotate the DIAL knob to select the desired signal strength level for the squelch threshold (LVL 1 - LVL8
or OFF).
5. Press the PTT switch to save the new setting and return to normal operation.
R.F. Says: 1) When the S-meter squelch is activated, blink the S-meter segment corresponding with the
squelch threshold which set by step 4 above.
2) The receiver’s squelch will open based on the higher of the levels 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.

5. Press the PTT switch to save the new setting and exit to normal operation.
Repeater Operation
Repeater stations, usually located on mountaintops or other high locations, provide a dramatic extension of
the communication range for low-powered hand-held or mobile transceivers. The VX-3R includes a number
of features which make repeater operation simple and enjoyable.
Repeater Shifts
Your VX-3R has been configured, at the factory, for the repeater shifts customary in your country. For the
144 MHz band shift will be 600 kHz; on the 430 MHz band, the shift may be 1.6 MHz, 7.6 MHz, or 5 MHz
(USA version).
Depending on the part of the band in which you are operating, the repeater shift may be either downward
(–) or upward (+), and one of these icons will appear at the top of the LCD when repeater shifts have been
enabled.
Automatic Repeater Shift (ARS)
The VX-3R provides a convenient Automatic Repeater Shift feature, which causes the appropriate repeater
shift to be applied automatically whenever you tune into the designated repeater sub-bands in your country.
These sub-bands are shown below.
If the ARS feature does not appear to be working, you may have accidentally disabled it.
To re-enable ARS:
1. Press and hold in the [TXPO] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 5: ARS.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
3. Press the [TXPO] key momentarily to enable adjustment of this Item.

normal operation.
Manual Repeater Shift Activation
If the ARS feature has been disabled, or if you need to set a repeater shift direction other than that
established by the ARS, you may set the direction of the repeater shift manually.
To do this:
1. Press and hold in the [TXPO] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 68: RPT.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
3. Press the [TXPO] key momentarily to enable adjustment of this Item.
4. Rotate the DIAL knob to select the desired shift among “–RPT,” “+RPT,” and “SIMP.”
5. When you have made your selection, press the PTT switch to save the new setting and return to
normal operation.
R.F. Says: If you make a change in the shift direction, but still have Automatic Repeater Shif t still engaged
(see previous section), when you change frequency (by rotating the DIAL knob, for example) the ARS will
over-ride your manual setting of the shift direction. Turn ARS off if you do not wish this to happen.
Changing the Default Repeater Shifts
If you travel to a different region, you may need to change the default repeater shift so as to ensure
compatibility with local operating requirements.
To do this, follow the procedure below:
1. Set the VX-3R’s frequency to the band on which you wish to change the default repeater shift (144
MHz or 430 MHz Ham Band).
2. Press and hold in the [TXPO] key for one second to enter the Set mode.
3. Rotate the DIAL knob to select Set Mode Item 69: RPT.SFT.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
4. Press the [TXPO] key momentarily to enable adjustment of this Item.
5. Rotate the DIAL knob to select the new repeater shift magnitude.
6. When you have made your selection, press the PTT switch to save the new setting and return to
normal operation.
R.F. Says: If you just have one “odd” split that you need to program, don’t change the “default” repeated
shifts using this Set Mode Item! Enter the transmit and receive frequencies separately, as shown on
page ??.

VX-3R Operating Manual
Checking the Repeater Uplink (Input) Frequency
It often is helpful to be able to check the uplink (input) frequency of a repeater, to see if the calling station is
within direct (“Simplex”) range.
To do this, just press the [HM/RV] key. You’ll notice that the display has shifted to the repeater uplink
frequency. Press the [HM/RV] key again to cause operation to revert to normal monitoring of the repeater
downlink (output) frequency.
R.F. Says: The configuration of this key may be set either to “RV” (for checking the input frequency of a
repeater), or “HM” (for instant switching to the “Home” channel for the band you are operating on). To
change the configuration of this key, use Set Mode Item 36: HM/RV. See page ??.
CTCSS/DCS/EPCS Operation
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.
R.F. Says: 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 Set Mode Items 79: SQ TYP and 86: TN FRQ.
1. Press the [F/W] key, then press the [MODE] key. This provides a “Short-cut” to Set Mode Item 79: SQ
TYP.
2. Rotate the DIAL knob so that “TONE” appears on the display; this activates the CTCSS Encoder,
which allows repeater access.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
3. Rotation of the DIAL knob one more “click” in step “2” above will cause the “T SQL” notation to appear.
When “TSQL” is displayed, this means that the Tone SQueLc h system is active, which mutes your
VX-3R’s receiver until it receives a call from another radio sending out a matching CTCSS tone. This
can help keep your radio quiet until a specific call is received, which may be helpful while operating in
congested
R.F. Says: 1) You may notice an additional “DCS” icon appearing while you rotate the DIAL knob in this
step. We’ll discuss the Digital Code Squelch system shortly.
2) You may notice “RV TN” indication on the display while you rotate the DIAL knob in this step, this
means that the Reverse Tone Squelch system is active, which mutes your VX-3R’s receiver when it
receives a call from the radio sending a matched CTCSS tone. The “TSQ” icon will blink on the display
when the Reverse Tone Squelch system is activated.
3) You may notice “PR FRQ” indication on the display while you rotate the DIAL knob in this step, this
means that User programmed Reverse CTCSS Decoder mutes your VX-3R’s receiver when it receives
19
Vertex Standard Co., Ltd.
FCC ID: K6620285X20
IC ID: 511B-20285X20
VX-3R Operating Manual
a call from the radio sending a matched your programmed matching tone (determine from Set Menu
Item: 63: PR FRQ) is received. The “SQ” icon will appear on the display when the User programmed
Reverse CTCSS Decoder is activated.
4) You may notice “PAGER” and “MESSAGE” indication on the display while you rotate the DIAL knob
in this step, these means that activating the “User programmed Reverse CTCSS Decoder”, “Enhanced
Paging & Code Squelch”, and the “Message Feature”. We’ll discuss later these functions.
4. When you have made your selection of the CTCSS tone mode, press the PTT switch to save the new
setting.
5. Press and hold in the [TXPO] key for one second to enter the Set mode.
6. Rotate the DIAL knob to select Set Mode Item 86: TN FRQ.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
7. Press the [TXPO] key momentarily to enable adjustment of the CTCSS frequency.
8. Rotate the DIAL knob until the display indicates the Tone Frequency you n eed to be using (ask the
repeater owner/operator if you don’t know the tone frequency).
9. When you have made your selection, press the [TXPO] key momentarily, then press the PTT switch, to
save the new settings and exit to normal operation. This is different than the usual method of restoring
normal operation, and it applies only to the configuration of the CTCSS/DCS frequencies.
R.F. Says: 1) Your repeater may or may not re-transmit a CTCSS tone - some systems just use CTCSS to
control access to the repeater, but don’t pass it along when transmitting. If the S-Meter deflects, but the
VX-3R is not passing audio, repeat steps “1” through “4” above, but rotate the DIAL so that “TSQ”
disappears - this will allow you to hear all traffic on the channel being received.
2) During CTCSS operation, you may set up the VX-3R such that a ringing “bell” sound alerts you to the fact
that a call is coming in. See page ?? for details.
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-3R, and operation is very similar to that just described for CTCSS.
Y our repeater system may be configured for DCS; if not, DCS is frequently quite useful in Simplex operation
if your friend(s) use transceivers equipped with this advanced feature.
R.F. Says: Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS and that you
select a tone code.
1. Press the [F/W] key, then press the [MODE] key. This provides a “Short-cut” to Set Mode Item 79: SQ
TYP.
2. Press the [TXPO] key momentarily to enable adjustment of this Item.

3. Rotate the DIAL knob until “DCS” appears on the display; this activates the DCS Encoder/Decoder.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
4. Press the PTT switch to save the new setting.
5. Press and hold in the [TXPO] key for one second to enter the Set mode.
6. Rotate the DIAL knob to select Set Mode Item 24: DCS CD.
7. Press the [TXPO] key momentarily to enable the adjustment of the DCS code.
8. 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 friend(s).
9. When you have made your selection, press the [TXPO] key momentarily, then press the PTT switch to
save the new settings and exit to normal operation.
R.F. Says: 1) Remember that the DCS is an Encode/Decode system, so your receiver will remain muted
until a matching DCS code is received on an incoming transmission. Switch the DCS off when you’re just
tuning around the band!
2) During DCS operation, you may set up the VX-3R such that a ringing “bell” sound alerts you to the fact
that a call is coming in. See page ?? for details.
DCS Code Inversion
The DCS system was first introduced in the commercial LMR (Land Mobile Radio) service, where it is now
in widespread use. DCS is sometime referred to by its different proprietary names, such as DPL
Private Line
®
, a registered trademark of Motorola, Inc.).
®
(Digital
DCS uses a codeword consisting of a 23-bit frame, transmitted (subaudible) 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:

R-N.T.I: Receive the Normal DCS Tone and transmit the Inverted DCS Tone.
R-I.T-I: Receive and transmit the Inverted DCS Tone.
R-B.T-I: Receive the both Normal and Inverted DCS Tones and transmit the Inverted DCS Tone.
5. When you have made your selection, press the [TXPO] key momentarily, then press the PTT switch, to
save the new settings and exit to normal operation.
This is different than 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) to when done.
Tone Search Scanning
In operating situations where you don’t know the CTCSS or DCS tone being used by another station or
stations, 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(s) 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 pre vious discussions). In the
case of CTCSS, “T SQ” will appear on the display; in the case of DCS, “DCS” will appear on the
display.
2. Press and hold in the [TXPO] key for one second to enter the Set mode.
3. Rotate the DIAL knob to select Set Mode Item 86: TN FRQ when TONE SQL is selected, or Set Mode
Item 24: DCS CD during DCS operation.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
4. Press the [TXPO] key momentarily to enable adjustment of the selected Set Mode Item.
5. Press and hold in the [BAND] key for one second, appear “T SRCH” (for CTCSS Tone Search) or “D
SRCH” (for DCS Tone Search) on the display, then release the [BAND] key to start scanning for the
22
Vertex Standard Co., Ltd.

VX-3R Operating Manual
incoming CTCSS or DCS tone/code.
6. 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 [BAND] key to lock in that tone/code, then press PTT to exit to normal operation.
R.F. Says: 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 may listen to the (muted) signal from the other station during Tone Scanning when Set Mode Item 88:
TS MUT is set to “OFF.” See page ?? for details. You can also change the Tone Search scanning speed,
using Set Mode Item 89: TS SPD. See page ??.
Tone Scanning works either in the VFO or Memory modes.
EPCS (Enhanced Paging & Code Squelch)
The VX-3R includes an Enhanced CTCSS tone encoder/decoder and a dedicated microprocessor
providing paging and selective calling features. This allows you to place a call to a specific station (Paging),
and to receive calls of your choice directed only to you (Code Squelch).
The paging and code squelch systems use two pairs of (alternately switched) CTCSS tones which are
stored in the pager memories. Basically, your receiver remains silent until it receives the CTCSS tone pair
that matches those stored in the Receiving Pager Memory. The squelch then opens so the caller is heard,
and the paging ringer immediately sounds, if activated. When you close the PTT switch to transmit, the
CTCSS tone pair which is stored in the Transmitting Pager Memory will be transmitted automatically.
On the paged radio, the squelch will close automatically after the incoming page ends. Meanwhile, on the
paging radio, the Enhanced Paging and Code Squelch system will be disabled after the PTT switch is
released after the paging transmission. You may re-activate the Enhanced Paging and Code Squelch
system again.
Storing the CTCSS Tone Pairs for EPCS Operation
1. Press and hold in the [TXPO] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 61: P AG.CDR for the Receiving CTCSS T on e Pair or Set
Mode Item 62: PAG.CDT for the Transmitting CTCSS Tone Pair.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
3. Press the [TXPO] key momentarily to enable adjustment of this Set Mode Item.
4. Rotate the DIAL knob to set the CTCSS Tone number which corresponds to the first tone of the CTCSS
Tone Pair.
5. Press the [V/M] key, then rotate the DIAL knob to set the CTCSS Tone number which corresponds to
the second tone of the CTCSS Tone Pair.

6. Press the PTT switch to save the new setting and exit to normal operation.
R.F. Says: The VX-3R does not recognize the order of the 1st tone and the 2nd tone. In other words, for
example, the VX-6R considers both CTCSS pairs “10, 35” and “35, 10” to be identical.
