GENERAL DESCRIPTION
The YAESU VR-160 is a high-performance micro-miniature communications receiver
covering frequencies from 100 kHz to 1299.995 MHz on the AM and FM (Wide and
Narrow bandwidths) modes. Coverage includes the AM and 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 incredibly small size allows you to take it anywhere - hiking, skiing, or walking around
town. Its operating flexibility brings the user many avenues of listening enjoyment. The
tiny FNB-82LI Lithium-Ion Battery Pack provides more than 20 hours of receiver operation.
The VR-160 internal antenna bar provides good AM broadcast reception without the need
of an external antenna.
The large High-resolution Dot Matrix LCD display provides clear, easily read frequency
indication. The Band Scope function provides a high-resolution display of the relative
signal strengths of up to ±50 adjacent channels!
Additional features include the CTCSS and DCS squelch system, which help prevent false
activation of the receiver by radar or spurious signals from other transmitters. A security
Password may be set, which will allow you to turn on and operate your radio only after the
Password is entered.
The S-Meter Squelch may be adjusted to open at a programmed signal level, thus reducing
guesswork in setting the squelch threshold.
Additional equipment may be connected to the top panel ACC jack for expanded operation.
We appreciate your purchase of the VR-160, and encourage you to read this manual thoroughly, to learn about the many exciting features of your new YAESU communications

VR-160 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 VR-160. 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 radio. 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 radio) 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 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 VR-160 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 13: BEEP SELECT. See page
77, 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 37: OPEN MESSAGE; see page 82 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 display while
adjusting the Speaker Output Level. The “HP” notation (which means Headphone)
appears in the 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

key again, the DIAL knob function returns to the frequency control. Furthermore, you
VR-160 OPERATING MANUAL12
OPERATION
ADJUSTING THE VOLUME LEVEL
may change the [VOL] key function via Set Mode Item 60: VOLUME MODE. See page
86 for details.
SQUELCH ADJUSTMENT
The VR-160’s Squelch system allows you to mute the background noise when no signal is
being received. The Squelch system makes “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
49: SQL LEVEL.
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 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 MONI switch
briefly to save the new setting and exit to normal operation.
1) The VR-160 squelch threshold level can be individually set on the AM
mode, FM mode, Wide FM mode, and AM Broadcast mode.
2) A special “S-meter Squelch” feature is provided on the VR-160. This feature allows you to set the squelch so only signals exceeding a certain S-meter level will
open the squelch. See page 21 for details.
VR-160 OPERATING MANUAL 13
OPERATION
SELECTING THE OPERATING BAND
The VR-160 covers an incredibly wide
frequency range, over which a number
of different operating modes are used.
Therefore, the VR-160’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 20).
To Change Operating Bands:
1. Press the [BAND] key repeatedly. You will see the LCD
indication move toward a higher frequency band each time
you press the [BAND] key.
The Band Number corresponding to the receiver frequency
of the selected Memory Channel will be displayed.
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.

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 68 for details.
VR-160 OPERATING MANUAL14
OPERATION
FREQUENCY NAVIGATION
The VR-160 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 VR-160:
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 VR-160 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 VR-160.
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 SCAN switch for
one second to show theVFO scanner bandwidth selections. Rotate the DIAL knob to select the desired bandwidth for the VFO
scanner, press the SCAN switch briefly 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 VR-160 will then hold on that frequency according to the setting of the “RESUME”
mode (Set Mode Item 45: SCAN RESUME). See page 83 for more 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 VR-160 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 SCAN switch briefly to stop the scanning.
Notice
The VR-160 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.

2) The receiver’s squelch will open based on the higher of the lev-
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.

TONE SQUELCH/DCS OPERATION
TONE SQUELCH OPERATION
Some Two-way FM Radio Stations superimpose a very-low-frequency audio tone on the
FM carrier. This helps prevent false activation of the station by radar or spurious signals
from other transmitters. This tone system, called “Tone Squelch”, is included in your VR-
160, and is very easy to activate.
Tone Squelch system 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 51: SQL TYPE and 55: TONE FREQUENCY.
1. Press the [F/W] key, then press the [MODE] key. This provides
a “Short-cut” to Set Mode Item 51: SQL TYPE.
2. Rotate the DIAL knob to select “TSQL”. This activates the Tone
Squelch system.
Note: Do not forget to pull the DIAL knob to rotate the DIAL
knob.

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 Tone Squelch system. The DCS is built into your VR-160, and operation is very
similar to that just described for Tone Squelch.
Just as in Tone Squelch operation, DCS requires that you set the Tone Mode
to DCS and that you select a digital code. These actions are set up by using
the [MODE] key or Set Mode Items 51: SQL TYPE and 23: DCS CODE.
1. Press the [F/W] key, then press the [MODE] key. This provides
a “Short-cut” to Set Mode Item 51: SQL TYPE.
2. Rotate the DIAL knob until “DCS” appears on the display; this

TONE SQUELCH/DCS OPERATION
DCS OPERATION
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® (Digital Private Line®, a registered trademark of Motorola, Inc.).
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:
1. Press and hold in the [BANK] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 24: DCS INVERSION.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
3. Press the [BANK] key briefly to enable adjustment of this Set
Mode Item.
4. Rotate the DIAL knob to select one of the following modes:
NORMAL: Receive the Normal DCS Tone.
REVERSE: Receive the Inverted DCS Tone.
BOTH: Receive both Normal and Inverted DCS Tones.
5. When you have made your selection, press and hold in the
[
BANK] key for one second to save the new settings and exit to
normal operation.
This is different from 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
to “NORMAL” when done.

TONE SQUELCH/DCS OPERATION
TONE SEARCH SCANNING
In operating situations where you don’t know the Tone Frequency or DCS code 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:
To scan for the tone in use:
1. Set the radio up for either Tone Squelch or
DCS operation (see the previous discussions). In the case of Tone Squelch, “TSQ”
will appear on the display; in the case of
DCS, “DCS” will appear on the display.
2. Press and hold in the [BANK] key for one second to enter the Set mode.
3. Rotate the DIAL knob to select Set Mode
Item 55: TONE FREQUENCY when TONE
SQL is selected, or Set Mode Item 23: DCS
CODE during DCS operation.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
4. Press the [BANK] key briefly to enable adjustment of the selected Set Mode Item.
5. Press the SCAN switch to start scanning for the incoming Tone Frequency or DCS
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 SCAN switch to lock in that tone/code, then
press and hold in the [BANK] key for one second to exit to normal operation.
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 SCAN switch to halt the scan at any time.
You may listen to the (muted) signal from the other station during Tone Scanning by changing
Set Mode Item 56: TONE-SCH MUTE to “OFF.” See page 86 for details. You can also
change the Tone Search scanning speed, using Set Mode Item 57: TONE-SCH SPEED. See
page 86.
Tone Scanning works either in the VFO or Memory modes.
