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.
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.
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.

PERATING MANUAL
If using an external antenna for transmission, ensure that the SWR presented to
the transceiver is 1.5:1 or lower.
Installation of FNB-82LI 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-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.
Referring to Figure 1, slide the Battery Cover toward the bottom to remove it while
slide the Battery Cover Latch.
Referring to Figure 2, install the FNB-82LI into the Battery Nest.
Replace the Battery Cover, as shown in Figure 3.
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, display will indicate “CHGING” and the TX/BUSY
indicator will glow red.
When charging is finished, display will change to indicate “CHGFUL” and the TX/BUSY
indicator will change to glow green.
Interface of Packet TNCs
The VX-2R 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-2R 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.

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-2R. 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 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 indicate on the display for 2 second. After this
interval, the display will resume its normal indication of the operating frequency.
3. To turn the VX-2R off, press and hold in the POWER switch again for one second.
R.F. says:
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 VOLUME control (inner knob) to set the desired audio level. Clockwise
rotation increases the volume level.
Squelch Adjustment
The VX-2R’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 and hold the [H/L(STEP)SET] key for one second to enter the Set Mode.
2. Rotate the DIAL knob to select the Set Mode Item 1: SQL.
3. Press the [H/L] key momentarily to enable adjustment this Item.
4. Rotate the DIAL knob to set the background noise is just silenced (typically at a
setting of about “1” or “2” for FM, and “2” or “3” for Wide-FM); this is point of
maximum sensitivity to weak signals.

5. When you are satisfied with the Squelch threshold setting, press the PTT key
momentarily to save the new setting and exit to normal operation.
R.F. Says:
1) A special “RF Squelch” feature is provided on the VX-2R. 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.
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-2R has, try using that mode for silent monitoring of busy
channels.
Selecting the Operating Band
The VX-2R covers an incredibly wide frequency range, over which a number of different
operating modes are used. Therefore, the VX-2R’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.
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 discussions on the next chapter.
Frequency Navigation
The VX-2R will initially be operating in the “VFO” mode, a channelized system which
allows free tuning throughout the currently-selected operating band.
Two basic frequency navigation methods are available on the VX-2R:
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-2R 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, 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-2R.
2) Scanning
From the VFO mode, press and hold the [BAND] key. The VX-2R 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-2R will then hold on that frequency
according to the setting of the “RESUME” mode (Set Mode Item 28: 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 one click in the counter-clockwise direction
while the VX-2R 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.
Transmission
Once you have set up an appropriate frequency inside one of the 144 MHz or 430 MHz
Amateur bands on which the VX-2R can transmit, 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 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 LCD.
Additionally, the “L” icon will appear at the bottom of the display while operating
on the “Low Power” Level setting.
R.F. Says:
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 [H/L] 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 possible only on the 144 MHz and 430 MHz bands.
R.F. Says:
1) The VX-2R is smart! You can set up Low power on 144 MHz band, while
