INTRODUCTION
The VX-7R is a miniature 3-band FM transceiver
with extensive receive frequency coverage, providing leading-edge features for VHF and UHF twoway amateur communications, along with unmatched
monitoring capability.
The VX-7R’s 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. Besides 50, 144,
and 430 MHz transceive operation, the VX-7R provides 222 MHz QRP (0.3 Watts) transceive operation, receive coverage of the AM (MF) and FM
broadcast bands, HF Shortwave Bands up to 16 MHz,
VHF and UHF TV bands, the VHF AM aircraft band,
and a wide range of commercial and public safety
frequencies! Dual In-band Receive (V/V and U/U)
lets you keep track of two active frequencies. And
the optional Barometer pressure Sensor Unit provides
readout of barometric pressure and altitude while
mountain climbing or hiking, and it also generates a
Weather Forecast based on measured data.
The transmitter section provides 5 Watts of clean
power output on the FM operation on the 50 MHz,
144 MHz, and 430 MHz bands with the supplied
FNB-80LI Battery Pack, and 0.3 Watts output on
222 MHz, and 1 Watt of carrier output for AM operation on 50 MHz. Both CTCSS and DCS tone signaling formats are built into the VX-7R, in addition
to Yaesu’s exclusive ARTSTM-(Auto-Range Transponder System), which “beeps” the user when you
move out of communications range with another
ARTSTM-equipped station.
We appreciate your purchase of the VX-7R, and encourage you to read this manual thoroughly, so as to
learn about the many exciting features of your exciting new Yaesu hand-held transceiver!

VX-7R OPERATING MANUAL6
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 overtighten by use of extreme force.
When operating the VX-7R 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-7R 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-80LI BATTERY PACK
The FNB-80LI is a high-performance Lithium-Ion battery providing high capacity in a
very compact package. Under normal use, the FNB-80LI 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-80LI as shown in the illustration.
2. Close the Battery Pack Latch on the bottom of the radio.
VX-7R OPERATING MANUAL8
INSTALLATION OF ACCESSORIES
NC-72B/C
INSTALLATION OF FNB-80LI BATTERY PACK
If the battery has never been used, or its charge is depleted, it may be charged by connecting the NC-72B/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.
The display will indicate “now charging” while the battery is being charged. When charging is finished, the display will change to indicate “complete” and the STROBE
indicator will glow blue.
E-DC-5B
E-DC-6
INSTALLATION OF FBA-23 ALKALINE BATTERY CASE (OPTION
The optional FBA-23 Battery Case allows receive monitoring using two “AA” size Alkaline batteries. Alkaline batteries can also be used for transmission in an emergency, but
power output will only be selectable 300 mW and 50 mW, and battery life will be shortened dramatically.
)
To Install Alkaline Batteries into the FBA-23
1. Slide the batteries into the FBA-23 as shown in the illustration,
with the Negative
connections inside the FBA-23.
2. Open the Battery Pack Latch on the bottom of the radio.
3. Install the FBA-23 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-23 does not provide connections for charging, since Alkaline cells cannot be re-
charged. Therefore, the NC-72B/C, E-DC-5B, or E-DC-6 may safely be connected to the
EXT DC jack when the FBA-23 is installed.
Notes:
¦ The FBA-23 is designed for use only with AA-type Alkaline cells.
¦ If you do not use the VX-7R for a long time, remove the Alkaline batteries from the
FBA-23, as battery leakage could cause damage to the FBA-23 and/or the transceiver.

)
The VX-7R may be operated from your house current by use of the supplied NC-72B/C
Battery Charger. The NC-72B/C should only be used for reception, because it is not capable of supplying sufficient current to support transmission.
To use the NC-72B/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.
VX-7R OPERATING MANUAL10
INTERFACE OF PACKET TNCS
The VX-7R 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 using the VOLUME
knob, as with voice operation. The input level to the VX-7R 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.
VX-7R OPERATING MANUAL 11
OPERATION
Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many
features of the VX-7R. I know you’re anxious to get on the air, but I encour-
age 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 left 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 40).
3. To turn the VX-7R 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 24, which tells you
how to reactivate the Beeper.
ADJUSTING THE VOLUME LEVEL
Rotate the VOLUME control (inner knob) to set the desired
audio level. Clockwise rotation increases the volume level.
24-hour Clock
The VX-7R 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 69.
VX-7R OPERATING MANUAL12
OPERATION
SQUELCH ADJUSTMENT
The VX-7R’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 MONI switch on the left
side of the radio. This provides a “Short-cut” to Menu
Item (Basic Setup #1: SQL NFM) or Menu Item (Basic
Setup #2: SQL WFM).
2. Now, press the or key 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 82
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 (subaudible) CTCSS tone. Or if your friends have radios
equipped with DCS (Digital Coded Squelch) like your VX-7R has, try using that mode
for silent monitoring of busy channels.
VX-7R OPERATING MANUAL 13
OPERATION
SELECTING THE OPERATING BAND
In the factory default configuration, the VX-7R operates in the “Dual Receive” mode.
During Dual Receive operation, the “Main” band frequency will be displayed on the upper
side of the LCD, and the “Sub” band 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 key momentarily to engage the “Main”
band frequency as the “Operating” band. Alternatively, press the key momentarily to
engage the “Sub” band frequency as the “Operating” band, described previously.

VX-7R OPERATING MANUAL14
OPERATION
SELECTING THE FREQUENCY BAND
The VX-7R covers an incredibly wide
frequency range, over which a number
of different operating modes are used.
Therefore, the VX-7R’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 25).
To Change Operating Bands
1. Press the key repetitively. You will see the LCD indication move toward a higher
frequency band each time you press the key. .
2. If you wish to move the operating band selection downward (toward lower frequen-
cies), press the key first, then press the key. .
3. The VX-7R uses a dual VFO system (described previously). To switch TX/RX opera-
tion from the “Main” VFO to the “Sub” VFO instantly, press the key momentarily. .
Pressing the key will return the VX-7R to the “Main” VFO. 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.

Dual Receive Notice
The VX-7R may receive very strong signals on the Image frequency, and/or the
receiver sensitivity may be somewhat reduced by the combination of the “Main”
and “Sub” 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.
¦ 3.579545 MHz x n ¦ 11.7 MHz x n (n is an integer: 1, 2, 3, …)
¦ “Main” band freq. = (“Sub” band freq. ± 46.35 MHz) x n
¦ “Sub” band freq. = (“Main” band freq. ± 47.25 MHz) x n (@ “Main band = NFM)
¦ “Sub” band freq. = (“Main” band freq. ± 45.8 MHz) x n (@ “Main band = WFM)
VX-7R OPERATING MANUAL 15
OPERATION
FREQUENCY NAVIGATION
The VX-7R 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-7R:
1) Tuning Dial (Outer ring of dual control on Top Panel)
Rotation of the DIAL allows tuning in the pre-programmed steps established for the current operating band. Clockwise rotation of the DIAL causes the VX-7R to be tuned toward
a higher frequency, while counter-clockwise rotation will lower the operating frequency.
If you press the key momentarily, then rotate the DIAL, 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-7R.
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-7R, 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 à à à à à
To enter 15.255 MHz, press à à à à à
To enter 1.250 MHz (1250 kHz), press à à à à à
To enter 0.950 MHz (950 kHz), press à à à à à
To enter 430.000MHz, press à à
3) Scanning
From the VFO mode, press the key, then press the key. The VX-7R will begin scanning toward a higher frequency, and will stop when it receives a signal strong enough to break
through the Squelch threshold. The VX-7R will then hold on that frequency according to the
setting of the “RESUME” mode (Menu Item: Scan Modes #3). See page 57 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 one click in the counter-clockwise direction while
the VX-7R is scanning. The scanning direction will be reversed. To revert to scanning
toward a higher frequency once more, rotate the DIAL one click clockwise.
Press the PTT switch momentarily to cancel the scanning.
VX-7R OPERATING MANUAL16
OPERATION
AUDIO MUTING
The Audio Mute feature is useful in situations where it would be helpful to reduce the
audio level of the “Receive Only” band (Small character display) whenever you receive a
signal on the “Main” band (Large character display) during Dual Receive operation.
To activate the Audio Mute feature:
1. Press the key, then press the key to enter the Set mode.
2. Rotate the DIAL to select the Menu Item labeled (Basic
Operation #8: MUTE SET).
3. Press the or key to select “ON” (to enable Audio
Mute feature).
4. Press the PTT switch to save the new setting and exit to
normal operation.
5. To disable the Audio Mute feature, select “OFF” in step 3
above.
When the Audio Mute feature is activated, the “ ” icon will appear on the display. .
BAND LINKING
For split operation on Amateur bands, the BAND Link feature may be useful.
1. Set up dual receive operation, as just described.
2. Press the key, then press the key to enter the Set mode.
3. Rotate the DIAL to select the Menu Item labeled (Misc
Setup #9: BAND LINK).
4. Press the or key to set this Menu Item to ON.
5. Press the PTT key to save the new setting and exit to
Linked/Dual receive operation.
As you rotate the DIAL, you will observe that both bands’ frequencies are changing together. When you are done with this operating mode, re-enter the Set mode, and set (Misc
Setup #9: BAND LINK) to OFF.
The BAND Link feature requires that (1) “Main” band and “Sub” band be
set to same band (Dual In-band receive), (2) Menu Item (Misc Setup #10:
VFO MODE) must be set to “BAND.” In other words, the BAND Link feature
cannot activated if “Main” band and “Sub” band are not set to the same band, or if
Menu Item (Misc Setup #10: VFO MODE) is set to “ALL.”
VX-7R OPERATING MANUAL 17
OPERATION
TRANSMISSION
Once you have set up an appropriate frequency inside one of the three (or four) Amateur
bands on which the VX-7R 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
“STROBE” 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. Full power
(5 Watts) is indicated by eight arrows below the frequency display. The three “Low
Power” levels (L1, L2, and L3) are indicated by two, four, or six arrows, respectively.
Additionally, the “L1,” “L2,” or “L3” icon will appear at the bottom of the display,
corresponding with the “Low Power” Level setting.
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 “L” icon appears at the bottom of the
display. And don’t forget: always have an antenna connected when you transmit.
Transmission is not possible on any operating bands other than the 50 MHz, 144 MHz, 222
MHz, and 430 MHz bands.
Changing the Transmitter Power Level
You can select between a total of four transmitter power levels on your VX-7R. The exact
power output will vary somewhat, depending on the voltage supplied to the transceiver.
With the standard FNB-80LI Battery
Pack and external DC source, the power
output levels available are:
To change the power level:
50/144/430 MHz
222 MHz FM

1. The default setting for the power output is “High;” in this configuration, the LCD
shows no indication of the power output level. 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
“Low Power” icon disappear and restore High Power operation.
1) The VX-7R 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, to cause the VX-7R to transmit (temporarily) on High power.
After one transmission, the power level will revert to the previously-selected Low power
setting.
VOX OPERATION
The VOX system provides automatic transmit/receive switching based on voice input to
the microphone. With the VOX system enabled, you do not need to press the PTT switch
in order to transmit, and it is not necessary to use a VOX headset in order to utilize VOX
operation.
1. Press the key, then press the key to enter the Set mode.
2. Rotate the DIAL to select the Menu Item labeled (Misc
Setup #7: VOX SENS).
3. Press the or key to select the desired VOX Gain
level (“HIGH” or “LOW”).
4. When you have made your choice, press the PTT key to save the new setting and
return to normal operation.
5. Without pressing the PTT switch, speak into the microphone in a normal voice level.
When you start speaking, the transmitter should be activated automatically. When you
finish speaking, the transceiver should return to the receive mode (after a short delay).
6. To cancel VOX and return to PTT operation, just repeat
the above procedures, selecting “OFF” in step 3 above.
When the VOX system is activated, the “ ” icon will appear
on the display.
The VX-7R provides for adjustment of the “Hang-Time” of the VOX system (the transmitreceive delay after the cessation of speech) via the Menu. The default delay is 1/2 second.
To set a different delay time:
1. Press the key, then press the key to enter the Set mode.
2. Rotate the DIAL to select the Menu Item labeled (Misc
Setup #8: VOX DELAY).
3. Press the or key to select the delay time among
“0.5sec,” “1sec,” and “2sec.”
4. When you have made your choice, press the PTT key to save the new setting and
return to normal operation.

OPERATION
AM BROADCAST RECEPTION
The VX-7R includes provision for reception of AM broadcasts, either on the standard
medium-wave (MW) broadcast band, or on the shortwave bands up to 16 MHz.
1. Set the VX-7R to the VFO mode on the “Main” band.
2. Press the key (or press à ) repetitively until
you see a frequency in the frequency range desired. The
MW coverage is 0.5 MHz to 1.8 MHz, while the shortwave broadcast coverage is 1.8 MHz to 16 MHz. In either
case, the operating mode (displayed on the right edge of the LCD) should be shown as
being “AM.”
3. Rotate the DIAL to tune across the broadcast band.
4. You may also use the keypad to enter frequencies directly. This method will be quicker
for changing from the 49-meter broadcast band to the 31-meter band, for example.
1) If the operating mode is not correct, you may need to adjust the setting of
the Menu Item labeled (Basic Setup #4: RX MODE). See page 26 for details.
2) The VX-7R includes a special memory bank into which the factory has
stored 89 frequencies representing popular Short-wave Broadcast stations. See page 55
for details.
AM AIRCRAFT RECEPTION
Reception of AM signals in the aeronautical band (108-137 MHz) is similar to that described in the previous section.
1. Be sure that the VX-7R is set to the VFO mode on the “Main” band.
2. Press the key (or press à ) repetitively until
you see a frequency in the aeronautical band.
3. Rotate the DIAL to tune across the aeronautical band.
4. You may also use the keypad to enter frequencies directly.
Remember that frequencies quoted by aircraft operators may be abbreviated, and that
the “5” at the end of a frequency may be dropped. Since aeronautical channels are
assigned in 25-kHz steps, therefore, a frequency announced as “thirty-two, forty-two”
corresponds to an operating frequency of 132.425 MHz.
