VX-8GR OPERATING MANUAL 1

The Ultra Compact VX-8GR (2.4”W x 3.7”H x 1.1”D) is equipped with a GPS receiver and

thinner than the previous advanced model - It is packed with advanced technology and fea-

tures, designed for outdoor operation. It is submersible (IPX5) and shockproof! The compact

case combines a rugged die-cast chassis with the clean, tough polycarbonate resin front panel.

Its shockproof versatility will allow you to operate the radio in the toughest environments.

The large High-resolution Dot Matrix LCD display provides clear, easy-to-read indication of

both “A” (Main band) and “B” (Sub band) frequencies, the operating mode, and S-meters for

both bands. When you engage the Spectrum Scope function, the high-resolution display will

indicate relative signal strengths of up to ±50 adjacent channels!

The built-in worldwide standard AX.25 Data TNC Modem permits uncomplicated APRS®

operation. (Automatic Packet/Position Reporting System: APRS® is a registered trademark of

the APRS Software and Bob Bruninga, WB4APR.) The VX-8GR supports APRS® 1200/9600

bps data communication on the “B” (Sub band) band only. You may communicate your loca-

tion to other APRS® stations along with the position, speed and heading displayed on your

radio! You and others will be able to see your APRS® movement on the web! The VX-8GR

displays the received station’s positions, heading directions, messages, distances, icons (43

kinds), weather information, object, etc. With the list function you may automatically store and

recall up to 20 messages and the APRS® data from up to 40 stations. The built-in GPS Receiver

Unit can provide you with your real time APRS® data.

An Enhanced Paging and Code Squelch (EPCS) 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 the transceiver only after you enter the Password. A convenient key pro-

vides access to Vertex Standard’s WIRES™ (Wide-Coverage Internet Repeater Enhancement

System). The Emergency Automatic ID (EAI) function can automatically cause your VX-8GR

to transmit your callsign and engage your rig’s microphone, even if you are disabled and un-

able to press the PTT switch. Additional 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 communica-

tions range with another ARTS™ equipped station. There is provision to reduce the TX devia-

tion 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. Provides a DATA jack which enable to displaying the location data (Lat/

Lon) of the after-market GPS receiver, outputs the location data (Lat/Lon) of the built-in GPS

receiver unit and the Waypoint data of the received APRS beacon.

We appreciate your purchase of the VX-8GR, and encourage you to read this manual thor-

oughly, and learn about the many exciting features of your thrilling new Yaesu hand-held

transceiver!

INSTALLATION OF FBA-39 ALKALINE BATTERY CASE (OPTION)

The optional FBA-39 Battery Case allows receive monitoring using three “AA” size Al-

kaline batteries. Alkaline batteries can also be used for low power transmission in an

emergency. The power output will only be selectable 1 W/50 mW (for 50/144/430 MHz

FM) or 500 mW/50 mW (for 222 MHz FM), or 1 W fixed (for 50 MHz AM).

TO INSTALL ALKALINE BATTERIES INTO THE FBA-39

1. Lift up the lower right corner of the rubber cover, and then open the cover (Figure 1).

2. Referring to Figure 2, slide the batteries into the FBA-39 as shown in the illustration,

with the Negative [–] side of the batteries touching the spring connections inside the

FBA-39.

3. Close the rubber cover.

4. Install the FBA-39 in the transceiver in the same manner as the FNB-101LI.

INSTALLATION OF ACCESSORIES

The FBA-39 does not provide connections for charging, since Alkaline cells cannot be

re-charged. Therefore, the NC-86B/C, E-DC-5B, or E-DC-6 may safely be connected to

the EXT DC jack when the FBA-39 is installed.

Notes:

The FBA-39 is designed for use only with AA-type Alkaline cells.

If you do not use the VX-8DR for a long time, remove the Alkaline batteries from the

FBA-39, as battery leakage could cause damage to the FBA-39 and/or the trans-

ceiver.

VX-8GR OPERATING MANUAL 13

Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many

features of the VX-8GR. I know you’re anxious to get on the air, but I en-

courage 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 it is fully charged. Connect the antenna

to the top panel ANTENNA jack.

2. Press and hold in the p(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. The open-

ing message will appear briefly on the display, then the

frequency display will appear. After another two sec-

onds, the receive-mode Battery Saver function will be-

come active, unless you have disabled it (see page xx).

3. To turn the VX-8GR off, press and hold in the p(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 27, which tells you

how to reactivate the Beeper.

ADJUSTING THE VOLUME LEVEL

Rotate the DIAL knob while pressing and holding the g

key to set the desired audio level. Clockwise rotation in-

creases the volume level.

1) The Volume level may be set on the

“A-Band” and “B-Band” separately.

2) You may set the Audio Output Level to the

Speaker, and the Earphone Output Level individually. The

“SP VOLUME” notation appears in the S- & PO meter area while adjusting the Speaker

Output Level. The “HP VOLUME” notation appears in the S- & PO meter area while

adjusting the Earphone Output Level.

3) Pressing the f key followed by the g key, the DIAL knob function changes to the

Volume Level adjustment instead of the frequency control. In this case, the “Volume

Level Indicator” on the display blinks. Pressing the f key followed by the g key

again, returns the DIAL knob function to the frequency control. You may also change

the g key function via Set Mode Item 99: VOLUME MODE. See page xx for details.

OPERATION

SQUELCH ADJUSTMENT

The VX-8GR’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 Broad-

cast) modes.

1. Press the f key, then press the e key on the left

side of the radio. This provides a “Short-cut” to Set

Mode Item 85: SQL LEVEL85: SQL LEVEL

85: SQL LEVEL.

2. Now, rotate the DIAL knob to the point where the back-

ground noise is just silenced (typically at a setting of

about “3” or “4” on the scale); this is the point of maxi-

mum sensitivity to weak signals.

3. When you are satisfied with the Squelch threshold setting,

press the PTT key briefly 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 xx 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 (sub audible) CTCSS tone. Or if your friends have radios

equipped with DCS (Digital Coded Squelch) like your VX-8GR, try using that mode for

silent monitoring of busy channels.

24-HOUR CLOCK

The VX-8GR 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 xx

2. If you wish to move the operating band selection down-

ward (toward lower frequencies), press the f key

first, then press the B key.

3. The VX-8DR uses a dual VFO system (described previously). To switch TX/RX op-

eration from the “VFO-A” to the “VFO-B” instantly, press the b key briefly. Pressing

the a key will return TX/RX operation to “VFO-A”. The frequency band shown in

“Large” characters is the band on which transmission is possible; the band shown in

“Small” characters may only be used for reception.

4. Once you have selected the desired band, you may initiate manual tuning (or scan-

ning). See the discussions on the next page.

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 xx for de-

tails.

VX-8GR OPERATING MANUAL 17

FREQUENCY NAVIGATION

The VX-8GR will initially be operating in the “VFO” mode, as just described. This is a fre-

quency step system which allows free tuning throughout the currently-selected operating band.

Three basic frequency navigation methods are available on the VX-8GR:

1) TUNING DIAL

Rotation of the DIAL knob allows tuning in the pre-pro-

grammed steps established for the current operating band.

Clockwise rotation of the DIAL knob causes the VX-8GR

to be tuned toward a higher frequency, while counter-clock-

wise rotation will lower the operating frequency.

If you press the f key briefly, 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-8GR.

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-8GR. However, there is a short-

cut for frequencies ending in zero - press the c key after the last non-zero digit.

Examples:

To enter 146.520 MHz, press 146520

To enter 430.000MHz, press 43c

OPERATION

Sub Band Operation

When press the key followed by the key, you can cause the controls

(except the TX function) to act on the “Sub” band. When

the Sub Band operation is activated, the Main band’s

“Frequency Control” icon will blinks. After making con-

trol to the Sub band, press the key followed by the

key to return control to the “Main” band.

VX-8GR OPERATING MANUAL18

3) SCANNING

From the VFO mode, press and hold in the B key for one second, and while still

holding in the B key, rotate the DIAL knob to select

the bandwidth for the VFO scanner. Release the B 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-8GR will then hold

on that frequency according to the setting of the “RESUMERESUME

RESUMERESUME

RESUME”

mode (Menu Item 77: SCAN RESUME77: SCAN RESUME

77: SCAN RESUME77: SCAN RESUME

77: SCAN RESUME).

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-8GR is scanning. The scanning direction will be reversed. To revert to

scanning toward a higher frequency once more, rotate the DIAL knob one click clock-

wise.

Press the PTT switch briefly to cancel the scanning. See page xx for more details regard-

ing Scan Operation.

OPERATION

FREQUENCY NAVIGATION

Dual Receive Notice

The VX-8GR may receive very strong signals on the Image frequency, and/or the

receiver sensitivity may be somewhat reduced by the combination of the “A-Band”

and “B-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.

VX-8GR OPERATING MANUAL 19

TRANSMISSION

Once you have set up an appropriate frequency inside one of the dual amateur bands on

which the VX-8GR can transmit (144 MHz or 430 MHz), 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 LED of the “A” or “B” which is designated the

“Main” band 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 “L1”, “L2”, “L3”,

or “HI” icon will appear at the left side of the PO meter,

corresponding with the “Power” Level setting.

1) If you’re just talking to friends in the immediate

area, you’ll get much longer battery life by switching to Low Power opera-

tion. To do this, press the f key, then press the d key so that the “Low

Power” icon appears at the bottom of the display. And don’t forget: always have an

antenna connected when you transmit.

2) Transmission is not possible on “Sub” band and any operating bands other than the

144 MHz and 430 MHz bands on the “Main” band.

3) Never transmit without having an antenna connected.

CHANGING THE TRANSMITTER POWER LEVEL

You can select between a total of four transmitter power levels on your VX-8GR. The

exact power output will vary somewhat, depending on the voltage supplied to the trans-

ceiver. With the standard FNB-101LI Battery Pack and external DC source, the power

output levels available are: “L1”, “L2”, “L3”, or “HI”

To change the power level:

1. The default setting for the power output is “High;” in

this configuration, the display shows the “HI” icon.

Pressing the f key, followed by the d key, causes

the power level “L1”, “L2”, or “L3” to appear.

2. Press the f key, followed by the d key (repeat-

edly, if necessary) to make the “HI” icon appear and

restore “High Power” operation.

VX-8GR OPERATING MANUAL20

OPERATION

1) The VX-8GR 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-

8GR to transmit (temporarily) on High power. After one transmission, the power level

will revert to the previously-selected Low power setting.

6.25, 8.33, 10, 12.5, 15, 20, 25, 50 and 100 kHz per step. The VX-8GR is set up at the

factory with different default steps for each operating band which are probably satisfactory

for most operation. However, if you need to change the channel step increments, the proce-

dure to do so is very easy.

1. Press the f key, then press the 1 key on the left side of the radio. This provides a

2) 5 kHz steps are not available for use on 250 - 300 MHz, nor above 580

MHz.

CHANGING THE RECEIVING MODE

The VX-8GR provides for automatic mode changing when the radio is tuned to different

operating frequencies. However, should an unusual receiv-

ing situation arise in which you need to change to a differ-

ent receiving mode, just press the key. The receiving

modes available are:

the squelch threshold which was set by step 4 above will blink.

2) The receiver’s squelch will open based on the higher of the levels set by the

Noise Squelch or the S-meter Squelch system.

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 SQL S-meter (Set Mode Item 93) is set to “LEVEL 5,” the squelch

will only open on signals which are “S5” or stronger on the S-meter.

b) If the SQL S-meter 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.

VX-8GR OPERATING MANUAL26

REPEATER OPERATION

GENERAL

Repeater stations, usually located on mountaintops or other high locations, provide a dra-

matic extension of the communication range for low-powered hand-held or mobile trans-

ceivers. The VX-8GR includes a number of features, which make repeater operation simple

and enjoyable.

REPEATER SHIFTS

Your VX-8DR has been configured, at the factory, for the repeater shifts customary in

your country. For the 144 MHz band, this usually will be 600 kHz, while the 430 MHz

shift will 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 bottom of the LCD when repeater

shifts have been enabled.

AUTOMATIC REPEATER SHIFT (ARS)

The VX-8GR provides a convenient Automatic Repeater Shift feature, which causes the

appropriate repeater shift to be automatically applied whenever you tune into the desig-

nated 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 the m key for one second to enter the Set Mode.

2. Rotate the DIAL knob to select Set Mode Item 6969

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 h key. You’ll notice that the display has shifted to the repeater

uplink frequency. Press the h key again to cause operation to

return to normal monitoring of the repeater downlink (output)

frequency. While you are listening on the input frequency of the

repeater using the h key, the repeater offset icon (“ ” or ”)

VX-8GR OPERATING MANUAL 29

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-8GR, and is

very easy to activate.

CTCSS setup involves two actions: setting the Tone Frequency and then set-

ting the Tone Mode. These functions are set up using Set Mode Items 88:

SQL TYP and 91: TONE FREQUENCY.

1. Press the f key, then press the M key. This provides a “Short-cut” to Set Mode

re-transmit a CTCSS tone - some

systems just use CTCSS to control

access to the repeater, but do not pass it along

when transmitting. If the S-Meter deflects,

but you cannot hear the 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-8GR so a ringing “bell” sound

alerts you to an incoming call. See page xx 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-8GR, and operation is

very similar to that just described for CTCSS. Your repeater system may be configured for

DCS. The DCS Squelch may be quite useful in Simplex operation if your friends use

transceivers equipped with this advanced feature.

Note: Just as in CTCSS operation, DCS requires that you set the Tone Mode to DCS

and that you select a DCS code.

just set up the DCS Code to be the same as that used by your friends.

6. When you have made your selection, press the 2 key to save the new settings and

exit to normal operation.

Remember that the DCS is an

Encode/Decode system, so your

receiver will remain muted until

a matching DCS code is received on an in-

coming transmission. Switch the DCS off

when you’re just tuning around the band!

VX-8GR OPERATING MANUAL32

DCS CODE INVERSION

The DCS system was first introduced in the commercial LMR (Land Mobile Radio) ser-

vice, 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 (sub audible) 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 the m key for one second to enter the Set Mode.

TONE SEARCH SCANNING

In operating situations where you don’t know the CTCSS or DCS tone being used by

another station, 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

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 previous dis-

cussion). In the case of CTCSS,

“TSQTSQ

TSQTSQ

TSQ” will appear on the display;

in the case of DCS, “DCSDCS

the B key to start scanning for the incoming CTCSS or DCS tone/code.

4. 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 B key to lock in that tone/code, then press

the 2 key 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 PTT switch to halt the scan at any time.

You can also press the e key during Tone Scanning to listen to the (muted) signal from

the other station. When you release the e key, Tone Scanning will resume after about a

second.

Tone Scanning works either in the VFO or Memory modes.

VX-8GR OPERATING MANUAL 35

CTCSS/DCS/EPCS OPERATION

EPCS (ENHANCED PAGING & CODE SQUELCH)

The VX-8GR includes an Enhanced CTCSS tone encoder/decoder and a dedicated micro-

processor 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 that is

stored in the Transmitting Pager Memory will be transmitted automatically.

On the paged radio, the Code 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.

MEMORY MODE (REGULAR MEMORY CHANNEL OPERATION)

MEMORY STORAGE

1. Select the desired frequency, while operating in the VFO mode. Be sure to set up any

desired CTCSS or DCS tones, as well as any desired repeater offset. The power level

may also be set at this time, if you wish to store it.

2. Press and hold in the f key for 1/2 second.

3. Within five seconds of releasing the f key, you need to make a decision regarding

channel storage. The microprocessor will automatically se-

lect the next-available “free” channel (a memory register

on which no data has been stored). If you do not wish to

make a change and accept the “free” channel, proceed to

step 4. If you wish to select a different channel number into which to store the data,

rotate the DIAL knob to select the desired memory channel.

Advice: You may jump 100 memory channels, if you’re in a hurry (101  201  301 …),

by pressing the m key (multiple times, if necessary). If you see the “ ” icon at the

upper left of the channel number, it means that the channel currently has no data

written on it (i.e. the channel is “free”: the occupied channel displays the “ ” icon).

4. Press the f key once more to store the frequency into memory.

5. You still will be operating in the “VFO” mode, so you may now enter other frequen-

cies, and store them into additional memory locations, by repeating the above pro-

cess.

1) You may change the automatic memory channel selection feature to select

the “next-highest memory channel above the last-stored memory channel”

instead of the “next-available ‘free’ channel” via the Set Mode Item 51:

MEMORY WRITE; see page xx.

2) You may disable the memory write function which prevents a memory write operation

if you should accidentally perform a wrong key sequence via the Set Mode Item 49:

MEMORY PROTECT. See page xx for details. When the memory write protect is acti-

vated, the “PROTECT” notation appears on the display while a memory write opera-

tion is being performed.

3) You may change the duration time of the secondary function (press and holding the

key) of the f key via the Set Mode Item 31: FW KEY HOLD TIME; see page xx.

IMPORTANT NOTE

On rare occasions the memorized data may become corrupted by miss operation,

or static electricity. When repairs are made the memory data may be lost. Please

write down or record the memorized information so you will be able to restore it if

needed.

STORING INDEPENDENT TRANSMIT FREQUENCIES (“ODD SPLITS”)

All memories can store an independent transmit frequency, for operation on repeaters

with non-standard shift. To do this:

1. Store the receive frequency using the method already described under MEMORY STOR-

AGE (it doesn’t matter if a repeater offset is active).

2. Tune to the desired transmit frequency, then press and hold in the f key for 1/2

second.

3. Within five seconds of releasing the f key, rotate the DIAL knob to select the same

memory channel number as used in step “1” above.

4. Press and hold in the PTT switch, then briefly press the f key once more while

holding the PTT switch in (this does not key the transmitter).

Whenever you recall a memory, which contains in-

dependently-stored transmit and receive frequen-

cies, the “ ” indication will appear in the display.

MEMORY RECALL

1. While operating in the VFO mode, press the c key to

enter the Memory mode.

2. Rotate the DIAL knob to select the desired channel.

3. If you press the f key briefly, then rotate the DIAL knob,

the memory channel will be selected in 10 channels per step.

4. To return to the VFO mode, press the c key.

1) When the radio is already set to the Memory mode, an easy way to recall

memories is to key in the memory channel number, then press the c key.

For example, to recall memory channel #14, press 14 c.

2) You may change the step of the fast channel selection mode (f key + DIAL knob)

via Set Mode Item 47: MEMORY FAST STEP. See page xx for details.

VX-8GR OPERATING MANUAL54

GENERAL

The VX-8GR allows you to scan just the memory channels, the entire operating band, or

a portion of that band. It will halt on signals encountered, so you can talk to the station(s)

on that frequency, if you like.

Scanning operation is basically the same in each of the above modes. Before you begin,

take a moment to select the way in which you would like the scanner to resume scanning

after it halts on a signal.

SETTING THE SCAN-RESUME TECHNIQUE

Three options for the Scan-Resume mode are available:

2.0sec - 10.0sec2.0sec - 10.0sec

2.0sec - 10.0sec: In this mode, the scanner will halt on a signal it encounters, and will

hold there for the selected resume time. If you do not take action to

disable the scanner within that time period, the scanner will resume

even if the station is still active.

BUSYBUSY

BUSY: In this mode, the scanner will halt on a signal it encounters. When the

carrier has dropped because the other station ceased transmission, the

scanner will resume. In the case of constant-carrier signals like Weather

Station broadcasts, the scanner will likely remain on this frequency

indefinitely. The Scan Re-start Delay time (default interval: 2 seconds)

is set by Set Mode Item 76: SCAN RE-START76: SCAN RE-START

76: SCAN RE-START76: SCAN RE-START

76: SCAN RE-START.

HOLDHOLD

HOLD: In this mode, the scanner will halt on a signal it encounters. It will not

restart automatically; you must manually re-initiate scanning if you

wish to resume.

To set the Scan-Resume mode:

HOW TO SKIP (OMIT) A FREQUENCY DURING VFO SCAN

If the VFO scan stops on a frequency or frequencies that you do not need (such as a

spurious radiation from a television), such frequencies can be “skipped” during VFO scan-

ning. A special “Frequency Skip Memory” bank is reserved to store these frequencies.

To skip a frequency during VFO scanning:

1. While VFO scanning is stopped on the frequency that you do not need, press and hold

the f key for one second, then rotate the DIAL knob to select the desired Fre-

quency Skip Memory channel (900900

900900

900 - 999999

999999

999). The microprocessor will automatically

select the next-available “free” Frequency Skip Memory channel (a memory register

on which no data has been stored). If you see the “ ” icon at the upper left of the

channel number, it means that the channel currently has no data written on it (i.e. the

channel is “free”).

2. Press the f key to store the frequency into the Frequency Skip Memory. It will now

be ignored during VFO scanning.

To re-institute a frequency into the VFO scan loop:

1. Press the c key, if needed, to enter the Memory Recall (“MR”) mode.

2. Press and hold in the f key for one second, then rotate the DIAL knob to select the

memory channel to be re-instituted.

3. Press the d key to delete the channel from the Frequency Skip Memory; this will

restore the frequency into the VFO scan loop.

The VX-8GR has 100 VFO Frequency Skip Memory Channels.

VFO SCANNING

SETTING THE SQUELCH LEVEL DURING ACTIVE SCANNING OPERATION

The VX-8GR allows adjustment of the Squelch level “on the fly” while you are

scanning.

1. While the scanner is engaged, press the key,

then press the key (the current squelch level

will appear below the frequency display).

2. Rotate the DIAL to select the desired Squelch level.

3. Press the PTT switch briefly to save the new setting and exit to normal op-

eration. In this case, pressing the PTT switch this one time will not causing

scanning to stop.

VX-8GR OPERATING MANUAL 59

HOW TO SKIP (OMIT) A CHANNEL DURING MEMORY SCAN

As mentioned previously, some continuous-carrier stations like a Weather Broadcast sta-

tion will seriously impede scanner operation if you are using the “Carrier Drop” Scan-

Resume mode, as the incoming signal will not pause long enough for the transceiver to

resume scanning. Such channels may be “Skipped” during scanning, if you like:

1. Recall the Memory Channel to be skipped during scanning.

2. Press the f key, then press the 5 key to appear a small

“” icon at the left of the frequency display. The current

Memory Channel will now be ignored (skipped) during

scanning (the “skipped” channel will, of course, still be ac-

cessible via manual channel selection methods using the DIAL knob in the Memory

Recall (“MR”) mode, whether or not it is locked out of the scanning loop).

To re-institute a channel into the scanning loop, press the f key followed by the 5

key twice, to disappear the small “” icon from display.

Note: You may notice a blinking “” icon while you perform above procedure. It indi-

cates the “Preferential Memory Scan” channel, described in the next column.

PREFERENTIAL MEMORY SCAN

The VX-8GR also allows you to set up a “Preferential Scan List” of channels which you

can “flag” within the memory system. These channels are designated by a blinking “”

icon when you have selected them, one by one, for the Preferential Scan List. When you

initiate memory scanning on a channel with the blinking “” icon appended, only those

channels bearing the blinking “” icon will be scanned. If you initiate scanning on a

channel which does not have the blinking “” icon appended, you will scan all channels

including those with the blinking “” icon appended.

Here is the procedure for setting up and using the Preferential Scan List:

1. Recall the Memory Channel which you wish to add to the Preferential Scan List.

2. Press the f key followed by the 5 key until a blinking

small “” icon appears at the left of the frequency display.

To clear the memory channel from the “Preferential Scan List”,

press the f key followed by the 5 key to disappear the

blinking small “” icon from display.

PROGRAMMABLE (BAND LIMIT) MEMORY SCAN (PMS)

This feature allows you to set sub-band limits for either scanning or manual VFO opera-

tion. For example, you might wish to set up a limit (in North America) of 144.300 MHz to

148.000 MHz to prevent encroachment into the SSB/CW “Weak Signal” portion of the

band below 144.300 MHz. Here’s how to do this:

1. Set the radio to the VFO mode by pressing the c key, if necessary.

2. Using the techniques learned earlier, store (per the above concept) 144.300 MHz into

Memory Channel #L1L1

L1L1

L1 (the “L” designates the Lower sub-band limit).

3. Likewise, store 146.000 MHz into Memory Channel #U1U1

U1U1

U1 (the “U” designates the

Upper sub-band limit).

4. Press and hold in the B key for one second and rotate

the DIAL knob while holding in the B key to select the

desired PMS frequency pair (PMSxxPMSxx

the DIAL knob (or press the a/b key) to scroll through

additional lines of station text on the display.

The received satellite number appears at the lower right of

compasses (In the example at the right, it is 4 satellites).

When receiving a signal from more than 3 satellites, the

“” icon will appear on the display.

Advice: 1) When the built-in GPS Antenna Unit is first turned on, it may take several

minutes to compute a fix of your position. This is normal, as the built-in GPS unit is

downloading “almanac” information from the GPS satellites.

2) While the VX-8GR searches for a GPS signal, the compass icon does not appear

on the display and the position information (Longitude/Latitude) blinks on the dis-

play.

3) If the VX-8GR does not receive a valid GPS signal after three minutes have passed,

you may be in a poor location for satellite reception, such as inside of a house or

building; try moving to a less obstructed position.

3. If you walk a few meters from your current location, your

course direction is displayed on the compass of the display

and walking speed is displayed in the “SPDSPD

display.

4. Press the M key to toggle the GPS screen between “North Up” and “Course Up”.

The course direction displays a black arrow in the “North Up” screen, and displays a

white arrow in the “Course Up” screen.

5. To return to normal operation, press the m key several times until the normal screen

appears.

1) When the VX-8DR GPS signal is interrupted; such as when you enter into a

tunnel, the compass icon disappears from the display but maintains the position

information (Longitude/Latitude) at the point where the GPS signal was lost.

2) When the built-in GPS Antenna Unit is activated, the current consumption increases

GPS OPERATION

FCC ID: K6620415X20 / IC:511B-20415X20

VX-8GR OPERATING MANUAL 83

The ARTSTM feature uses DCS signaling to inform both parties when you and another

ARTSTM-equipped station are within communications range. This may be particularly

useful during Search-and Rescue situations, where it is important to stay in contact with

other members of your group.

Both stations must set up their DCS codes to the same code number, then activate their

ARTSTM feature using the command appropriate for their radio. Alert ringers may be

activated, if desired.

Whenever you push the PTT, or every 25 (or 15) seconds after

ARTSTM is activated, your radio will transmit a signal which

includes a (subaudible) DCS signal for about 1 second. If the

other radio is in range, the beeper will sound (if enabled) and

the display will show “IN RNGIN RNG

IN RNGIN RNG

IN RNG” as opposed to the out of range

display “OUTRNGOUTRNG

OUTRNGOUTRNG

OUTRNG” in which ARTSTM operation begins.

Whether you talk or not, the polling every 15 or 25 seconds will

continue until you de-activate ARTSTM. Every 10 minutes, more-

over, you can have your radio transmit your callsign via CW, to comply with identifica-

tion requirements. When ARTSTM is de-activated, DCS will also be deactivated (if you

were not using it previously in non-ARTSTM operation).

If you move out of range for more than one minute (four pollings), your radio will sense

that no signal has been received, three beeps will sound, and the display will revert to

“OUTRNGOUTRNG

OUTRNGOUTRNG

OUTRNG”. If you move back into range, your radio will again beep, and the display will

change back to the “IN RNGIN RNG

IN RNGIN RNG

IN RNG” indication.

During ARTSTM operation, your operating frequency will continue to be displayed, but no

changes may be made to it or other settings; you must terminate ARTSTM in order to

resume normal operation. This is a safety feature designed to prevent accidental loss of

contact due to channel change, etc.

the “OUTRNGOUTRNG

OUTRNGOUTRNG

OUTRNG” display on the LCD below the operating

frequency. ARTSTM operation has now commenced.

3. Every 25 seconds, your radio will transmit a “polling” call

to the other station. When that station responds with its own

ARTSTM polling signal, the display will change to “IN RNGIN RNG

IN RNGIN RNG

IN RNG”

to confirm that the other station’s polling code was received

in response to yours.

4. Press the 4 key to exit ARTSTM operation and resume normal functioning of the

transceiver.

ARTSTM won’t work if you have used the Lock feature to disable the PTT!

ARTSTM POLLING TIME OPTIONS

The ARTSTM feature may be programmed to poll every 25 seconds (default value) or 15

seconds. The default value provides maximum battery conservation, because the polling

signal is sent out less frequently. To change the polling interval:

ARTSTM ALERT BEEP OPTIONS

The ARTSTM feature allows two kinds of alert beeps (with the additional option of turning

them off), to alert you to the current status of ARTSTM operation. Depending on your

location and the potential annoyance associated with frequent beeps, you may choose the

Beep mode which best suits your needs. The choices are:

IN RANGEIN RANGE

IN RANGE: The beeps are issued only when the radio first confirms that you are

within range, but does not re-confirm with beeps thereafter.

ALWAYSALWAYS

ALWAYS: Every time a polling transmission is received from the other station, the

alert beeps will be heard.

OFFOFF

OFF: No alert beeps will be heard; you must look at the display to confirm

current ARTSTM status.

VX-8GR OPERATING MANUAL88

The Smart Search feature allows you to load frequencies automatically according to where

activity is encountered by your radio. When Smart Search is engaged, the transceiver will

search above and below your current frequency, storing active frequencies as it goes (with-

out stopping on them even briefly); these frequencies are stored into a special Smart Search

memory band, consisting of 31 memories (15 above the current frequency, 15 below the

current frequency, plus the current frequency itself).

Two basic operating modes for Smart Search are available:

SINGLESINGLE

SINGLE: In this mode, the transceiver will sweep the current band once in each

direction starting on the current frequency. All channels where activity is

present will be loaded into the Smart Search memories; whether or not

all 31 memories are filled, the search will stop after one sweep in each

direction.

CONTINUOUSCONTINUOUS

CONTINUOUS: In this mode, the transceiver will make one pass in each direction as with

One-Shot searching; if all 31 channels are not filled after the first sweep,

however, the radio will continue sweeping until they are all filled.

The Smart Search feature can only be activated while the VX-8GR is operating

in the Mono band mode.

EMERGENCY CHANNEL OPERATION

The VX-8GR includes an “Emergency” feature, which may be useful if you have some-

one monitoring on the same frequency as your transceiver’s UHF “Home” channel. See

page ?? for details on setting the Home channel.

The “Emergency” feature is activated by pressing and holding in the h key for one

second.

When this is done, (A) the radio is placed on the UHF amateur band Home channel, (B) it

emits a loud “Alarm” sound (the volume is controlled by rotating the DIAL knob while

pressing and holding the g key), (C) it flashes the LED light in white, (D) if you press

the PTT switch, you will disable the Emergency feature temporarily. You can then trans-

mit on the UHF Home channel, and (E) two seconds after the PTT switch release, the

Emergency feature will resume.

To disable the “Emergency” feature, press and hold the h key for one second or turn the

radio Off by pressing and holding in the p(PWR) switch for one second.

Use this feature if you are out for a walk and want a quick way of alerting a family

member to a dangerous situation. The alarm sound may discourage an attacker and allow

you to escape.

1) Be sure to arrange with a friend or family member to be monitoring on the

same frequency, as there will be no identification sent via the Emergency

alarm sound. And do not transmit the alarm tone except in a true emergency!

2) The LED light may be changed to another function via Set Mode Item 29: EMER-

EMERGENCY FEATURE

EMERGENCY AUTOMATIC ID (EAI) FEATURE

The Emergency Automatic ID (EAI) feature can be used to aid in searching for persons

who are incapacitated in disasters like earthquakes, especially search-and-rescue person-

nel who may have become injured in a debris field. When using the EAI feature, a searcher

transmits a unique command (CTCSS tone pair), which will automatically cause the in-

jured party’s radio to transmit, so others may perform direction-finding and effect a res-

cue. The incapacitated party may not be able to speak or even press the PTT switch. The

callsign of the incapacitated person will also be transmitted, to assist the rescue team.

If an emergency group is working in a dangerous area, all members should engage the

EAI feature on their transceiver, so that others can assist a fallen team member, if neces-

sary.

The Emergency Automatic ID (EAI) Feature has two operating modes: (1) Interval mode

and (2) Continuous mode.

In the Interval mode (when the VX-8GR receives the CTCSS tone pair), the radio will

automatically transmit a brief (0.5 second) beep tone every 2.5 seconds until the EAI

timer expiration.

In the continuous mode, the radio will automatically transmit continuously (with maxi-

mum microphone gain), until the EAI timer expiration.

The EIA is activated when the CTCSS tone pair stored in the Receiving Pager Code Memory

(configured via Set Mode Item 62: PAGE CODE-RX62: PAGE CODE-RX

62: PAGE CODE-RX62: PAGE CODE-RX

62: PAGE CODE-RX) is received for 5 seconds on the

frequency, which is stored in Memory Channel “EAIEAI

EAIEAI

EAI”. It is NOT necessary for the inca-

pacitated person to press the PTT switch.

If your call sign is stored in the radio and the CW identifier is enabled via Set Mode Item

16: CW ID16: CW ID

16: CW ID, the radio will transmit your callsign on the air when the EAI feature is first

activated by the remote page, and every 10 minutes thereafter. The “callsign” ID can be

changed to any desired sequence of characters, such as a name. After sending the callsign

or name, the radio will repeatedly transmit three tones for a user-defined period of time

(between 1 and 30 minutes). The callsign or name will be transmitted every 10 minutes.

The Emergency Automatic ID (EAI) Feature requires that you (1) store the CTCSS Tone

Pair into the Receiving Pager Memory (see page xx for procedure), and (2) store the

desired UHF coordination frequency into Memory Channel “EAIEAI

EAIEAI

EAI” (see page 47 for proce-

dure).

mission, causing your TNC not to receive the full data burst.

TX BATTERY SAVER

The VX-8GR also includes a useful Transmit Battery Saver, which will automatically

lower the power output level when the last signal received was very strong. For example,

when you are in the immediate vicinity of a repeater station, there generally is no reason to

use the full 5 Watts of power output in order to achieve full-quieting access to the repeater.

With the Transmit Battery Saver, the automatic selection of Low Power operation con-

serves battery drain significantly.

BUSY CHANNEL LOCK-OUT (BCLO)

The BCLO feature prevents the radio’s transmitter from being activated if a signal strong

enough to break through the “noise” squelch is present. On a frequency where stations

using different CTCSS or DCS codes may be active, BCLO prevents you from disrupting

their communications accidentally (because your radio may be muted by its own Tone

Decoder). The default setting for the BCLO is OFF, and here is how to change that setting:

1. Press and hold the m key for one second to enter the Set Mode.

2. Rotate the DIAL knob to select Set Mode Item 7: BCLO7: BCLO

1. Press and hold the m key for one second to enter the Set Mode.

2. Rotate the DIAL knob to select Set Mode Item 32: HALF32: HALF

VX-8GR OPERATING MANUAL122

The VX-8GR includes a convenient “Clone” feature, which allows the memory and con-

figuration data from one transceiver to be transferred to another VX-8GR. This can be

particularly useful when configuring a number of transceivers for a public service opera-

tion. Here is the procedure for Cloning one radio’s data to another:

1. Turn both radios off.

2. Connect the optional CT-144 Clone Cable between the DATA jacks of the two ra-

dios.

3. Press and hold in the f key while turning the radios on.

Do this for both radios (the order of switch-on does not

matter). “CLONECLONE

CLONECLONE

CLONE” will appear on the displays of both ra-

dios when the Clone mode is successfully activated in this

step.

4. On the Destination radio, press the M key (“- WAIT -- WAIT -

- WAIT -- WAIT -

STATUS: These resisters sum up (combine) the “LOW SPD” through “TURN TIME”

items parameters in the “TYPE 1”, “TYPE 2”, or “TYPE 3” settings.

When STATUS is set to “TYPE 1”, “TYPE 2”, or “TYPE 3”, the

SmartBeaconingTM is activated with parameters of that setting.

When STATUS is set to “OFF”, the SmartBeaconingTM function is dis-

abled.

LOW SPD: This item designates the lower speed threshold. The VX-8GR transmits an

APRS beacon when your movement speed becomes lower than the se-

lected speed. The transmission interval time of the APRS beacon is set in

“SLOW RATE” item. The speed unit is determined from the APRS/GPS

Set Mode Item 10: APRS UNIT.

HIGH SPD: This item designates the higher speed threshold. The VX-8GR transmits

an APRS beacon when your movement speed becomes higher than the

selected speed. The transmission interval time of the APRS beacon is set

in “FAST RATE” item. The speed unit is determined from the APRS/GPS

Set Mode Item 10: APRS UNIT.

SLOW RATE: This item designates the transmission interval time of the APRS beacon at

low movement speeds.

FAST RATE: This item designates the maximum transmission interval time of the APRS

beacon at high movement speeds.

TURN ANGL: This item designates the course change angle that indicates a progress

heading change.

TURN SLOP: This item sets a coefficient to modify the TURN ANGLE algorithm, thus

increasing the beacon rate for lower movement speeds.

When this setting value is increased, the threshold angles of the APRS

beacon timing are increased as the vehicle velocity is decreased.

TURN TIME: This item designates the minimum delay time between each APRS bea-

con. The VX-8GR does not transmit an APRS beacon until this setting

time has elapsed since the previous APRS beacon transmission, prevent-

ing too frequent beacon transmissions.
