INTRODUCTION

The Ultra Compact VX-8R (2.4”W x 3.7”H x 0.9”D) is thinner than the previous advanced model - It is packed with advanced technology and features, designed for outdoor operation. It is submersible 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 Bluetooth® capabilities, already known and utilized among users and enthusiasts of the FTM-10R/SR, are also available with the VX-8R. The optional Bluetooth® Unit BU-1 makes it possible to operate Hands-free with the optional waterproof Bluetooth® headsets BH-1 (Stereo) or BH-2 (monaural).

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-8R supports APRS® 1200/9600 bps data communication on the B band only. You may communicate your location 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-8R 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 optional GPS Antenna Unit FGPS- 2 can provide you with your real time APRS® data. You may also send the information without the FGPS-2 if you manually input your data in advance.

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 provides access to Vertex Standard's WIRES™ (Wide-Coverage Internet Repeater Enhancement System). The Emergency Automatic ID (EAI) function can automatically cause your VX-8R to transmit your callsign and engage your rig’s microphone, even if you are disabled and unable 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 communications range with another ARTS™ equipped station. There is provision to reduce the TX deviation 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 completely independent FM/AM broadcast receiver and an internal bar antenna for better AM broadcast reception. Listen to FM broadcasts in stereo with your stereo headset/earphone!

We appreciate your purchase of the VX-8R, and encourage you to read this manual thoroughly, and learn about the many exciting features of your thrilling new Yaesu hand-held transceiver!

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 over-tighten by use of extreme force.

When operating the VX-8R 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-8R may be operated on frequencies higher than the 50 MHz band while the Extender Element is still attached to the Antenna Base.

Notes:

Never transmit without having an antenna connected.Carefully turn the supplied antenna onto the SMA jack.

Never twist the upper part of the antenna while screwing it onto the mating connector of 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, do not lose the antenna cap when removing it from the Base Antenna.

BELT CLIP INSTALLATION

Install the supplied Belt Clip to the FNB-101LI

 

Battery Pack using the supplied two screws

 

(Figure 1). Use only the screws included with

 

the Belt Clip to mount the Belt Clip to the back

 

of the Battery Pack!

 

If you do not need the Belt Clip, install the sup-

 

plied Plastic Cap to the Battery Pack (Figure

INSTALLATION OF ACCESSORIES

INSTALLATION OF FNB-101LI BATTERY PACK

The FNB-101LI is a high-performance Lithium-Ion battery providing high capacity in a very compact package. Under normal use, the FNB-101LI may be used for approximately 300 charge cycles, after which operating time may be expected to decrease. An old battery pack, which is displaying diminished capacity should be replaced with a new one.

To install the FNB-101LI Battery Pack, carefully mate the battery’s three alignment tabs with their corresponding alignment slots on the transceiver bottom case, then gently press the top side of the Battery Pack until it locks in place with a “click”.

To remove the Battery Pack, turn the transceiver off and

remove any protective cases. Press the Battery Pack Release

Knobs downward to unlock the latch, then remove the Bat-

tery Pack from the transceiver.

INSTALL

The VX-8R battery must be correctly installed, to

BATTERY PACK RELEASE KNOB

maintain the waterproof integrity.

 

REMOVE

If the battery has never been used, or its charge is depleted, it may be charged by connecting the NC-86B/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 DC Adapter (with its cigarette lighter plug) or E-DC-6 DC Cable may also be used for charging the battery, as shown in the illustration.

While the battery is being charged, the display will indicate “CHARGING” and the key will glow red. The S-meter will deflect according to the charging status. When charging is finished, the display will change to indicate “COMPLETE” and the key will glow green.

INSTALLATION OF ACCESSORIES

INSTALLATION OF FBA-39 ALKALINE BATTERY CASE (OPTION)

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

Figure 1

Figure 2

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-8R 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 transceiver.

INTERFACE OF PACKET TNCS

The VX-8R may be used for Packet operation, using the optional CT-44 and CT-131 microphone adapter (available from your Yaesu dealer) for easy interconnection to com- monly-available connectors wired to your TNC. You may also build your own cable using a four-conductor miniature phone plug.

The audio level from the receiver to the TNC may be adjusted by rotating the DIAL knob while pressing and holding the key, as with voice operation. The input level to the VX-8R 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, to prevent voltage spikes from damaging your transceiver.

VX-8R OPERATING MANUAL

OPERATION

Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many features of the VX-8R. 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 it is fully charged. Connect the antenna to the top panel ANTENNA jack.

2.Press and hold in the (PWR) switch (on the right side of the front panel) for 2 seconds. Two beeps will be

heard when the switch has been held long enough. The

opening message will appear briefly on the display, then the frequency display will appear. After another two seconds, the receive-mode Battery Saver function will be-

come active, unless you have disabled it (see page 125).

3. To turn the VX-8R 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 27, which tells you how to reactivate the Beeper.

ADJUSTING THE VOLUME LEVEL

Rotate the DIAL knob while pressing and holding the key to set the desired audio level. Clockwise rotation increases 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 key followed by the 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 key followed by the key again, returns the DIAL knob function to the frequency control. You may also change the key function via Set Mode Item 107: VOLUME MODE. See page 133 for details.

VX-8R OPERATING MANUAL

OPERATION

SQUELCH ADJUSTMENT

The VX-8R’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 key on the left side of the radio. This provides a “Short-cut” to Set Mode Item 92: SQL LEVEL.

2. Now, rotate the DIAL knob to the point where the background noise is just silenced (typically at a setting of about “3” or “4” on the scale); this is the point of maximum 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 157 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-8R, try using that mode for silent monitoring of busy channels.

24-HOUR CLOCK

The VX-8R 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 120.

VX-8R OPERATING MANUAL

OPERATION

SELECTING THE OPERATING BAND

In the factory default configuration, the VX-8R operates in the “Dual Receive” mode.

During Dual Receive operation, the “A-Band” frequency will be displayed on the upper part of the LCD, and the “B-Band” frequency will be displayed on the lower part. The “Operating” band (the band on which transmission and band/frequency changes are possible) is shown in large characters, and “Receive only” band is shown in small characters.

Press the key briefly to engage the “A-Band” frequency as the “Operating” band. Alternatively, press the

key briefly to engage the “B-Band” frequency, as described previously.

Press and hold in the or key for 1/2 seconds to switch to Mono Band Operation. During Mono band operation, you may change the display between “double-size character” and “large character” by pressing the / key.

TO CHANGE OPERATING BANDS

 

 

1. Press the

key repeatedly. You will see the LCD

 

indication change to a higher frequency band each time

 

you press the

 

key. A Band Number according to

 

the receiving frequency is also displayed.

 

 

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

 

ward (toward lower frequencies), press the

key

 

first, then press the

key.

 

 

 

3. The VX-8R uses a dual VFO system (described previ- ously). To switch TX/RX operation from the “VFO-A” to the “VFO-B” instantly, press the key briefly. Pressing the 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 scanning). See the discussions on the next page.

1)SW Band and Information Band reception is only possible on the “VFO-A”.

2)The VX-8R has an AM/FM Broadcast band radio. You can receive these bands independently. See page 22 for details.

3) 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 132 for details.

VX-8R OPERATING MANUAL

OPERATION

FREQUENCY NAVIGATION

The VX-8R will initially be operating in the “VFO” mode, as just described. This is a frequency step system which allows free tuning throughout the currently-selected operating band.

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

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-8R to be tuned toward a higher frequency, while counter-clock- wise rotation will lower the operating frequency.

If you press the 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-8R.

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-8R, 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 Æ To enter 15.255 MHz, press Æ To enter 1.250 MHz (1250 kHz), press To enter 0.950 MHz (950 kHz), press To enter 430.000MHz, press Æ

FREQUENCY NAVIGATION

3) SCANNING

From the VFO mode, press and hold in the key for one second, and while still holding in the key, rotate the DIAL knob to select the bandwidth for the VFO scanner. Release the 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-8R will then hold on that frequency according to the setting of the “RESUME” mode (Menu Item 83: 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-8R is scanning. The scanning direction will be reversed. To revert to scanning toward a higher frequency once more, rotate the DIAL knob one click clockwise.

Press the PTT switch briefly to cancel the scanning. See page 60 for more details regarding Scan Operation.

You may initiate upward or downward scanning by pressing and holding either or key for one second, respectively. In this case, the scanner scans the bandwidth that was previously selected.

Dual Receive Notice

The VX-8R 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-8R OPERATING MANUAL

OPERATION

TRANSMISSION

Once you have set up an appropriate frequency inside one of the three (or four) Amateur bands on which the VX-8R 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 lower right-hand

 

corner of the speaker grille) in a normal voice level.

 

The LED of the

or

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 operation. To do this, press the key, then press the 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 50 MHz, 144 MHz, 222 MHz (USA version), and 430 MHz bands on the “Main” band.

CHANGING THE TRANSMITTER POWER LEVEL

You can select between a total of four transmitter power levels on your VX-8R. The exact power output will vary somewhat, depending on the voltage supplied to the transceiver. 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 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 “HI” icon appear and restore “High Power” operation.

OPERATION

TRANSMISSION

1) The VX-8R 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,

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.

REPEATER OPERATION

GENERAL

Repeater stations, usually located on mountaintops or other high locations, provide a dramatic extension of the communication range for low-powered hand-held or mobile transceivers. The VX-8R includes a number of features, which make repeater operation simple and enjoyable.

REPEATER SHIFTS

Your VX-8R has been configured, at the factory, for the repeater shifts customary in your country. For the 50 MHz band, this usually will be 1 MHz, while the 144 MHz shift will be 600 kHz; on 70 cm, the shift may be 1.6 MHz, 7.6 MHz, or 5 MHz (USA version).

Depending on the part of the band in which you are operating, the repeater shift may be either downward ( ) or upward ( ),

and one of these icons will appear at the bottom of the LCD when repeater shifts have been enabled.

AUTOMATIC REPEATER SHIFT (ARS)

The VX-8R provides a convenient Automatic Repeater Shift feature, which causes the appropriate repeater shift to be automatically applied whenever you tune into the designated repeater sub-bands in your country. These sub-bands are shown below.

If the ARS feature does not appear to be working, you may have accidentally disabled it.

To re-enable ARS:

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

2.Rotate the DIAL knob to select Set Mode Item 74: RPT ARS.

CTCSS/DCS/EPCS OPERATION

CTCSS OPERATION

Many repeater systems require that a very-low-frequency audio tone be superimposed on your FM carrier in order to activate the repeater. This helps prevent false activation of the repeater by radar or spurious signals from other transmitters. This tone system, called “CTCSS” (Continuous Tone Coded Squelch System), is included in your VX-8R, and is very easy to activate.

CTCSS setup involves two actions: setting the Tone Frequency and then setting the Tone Mode. These functions are set up using Set Mode Items 94: SQL TYP and 98: TONE FREQUENCY.

1. Press the

key, then press the

key. This provides a “Short-cut” to Set Mode

Item 95: SQL TYPE.

 

2.Rotate the DIAL knob so that “TONE” appears on the display. This activates the CTCSS Encoder.

3. Rotation of the DIAL knob one more “click” in step “2” above will also activate the “TSQL” decode function. When “TSQL” is displayed, the Tone Squelch system is active, which mutes your VX-8R’s receiver until it receives a call from another radio sending out a matching CTCSS tone. This can helpful in a high RF congested location by keeping your radio quiet until a call is received from a specific station with a matching CTCSS tone.

You may notice an additional “DCS” indication appearing while you rotate the DIAL knob in step 3 above. We’ll discuss the Digital Code Squelch system shortly.

You may notice “REV TONE” indication on the display while you rotate the DIAL knob in step 3 above. When the Reverse Tone Squelch system is active, the VX-8R’s receiver is muted when it receives a call from a radio sending a matching CTCSS tone. The “RTN” icon will appear on the display when the Reverse Tone Squelch system is activated.

You may notice “PR FREQ” indication on the display while you rotate the DIAL knob in step 3 above, this means the user programmed Reverse CTCSS Decoder will mute your VX-8R’s receiver when it receives a call from a radio sending a CTCSS tone matching your programmed tone (determine by Set Mode Item 70: PR FREQUENCY). The “PR” icon will appear on the display when the Reverse CTCSS Decoder is activated.

You may notice “PAGER” and “MESSAGE” indication on the display while you rotate the DIAL knob in step 3 above. These appear when the “Enhanced Paging & Code Squelch” and the “Message Feature” are activated. We’ll discuss these functions later.

CTCSS OPERATION

4.When you have made your selection of the CTCSS tone mode, press the key to save the new setting and exit to normal operation.

5.Press the key, then press the key. This provides a “Short-cut” to Set Mode Item 99: TONE FREQUENCY.

6.Rotate the DIAL knob until the display indicates the fre- quency of the CTCSS tone that you need to send on your

transmission (ask the repeater owner/operator if you don’t know the tone frequency).

7.When you have made your selection, press the key briefly to save the new setting 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.

1) The repeater may or may not re-transmit a CTCSS tone - some systems just use CTCSS to control

access to the repeater, but do not pass it along 100.0 103.5 107.2 110.9 114.8 118.8 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-8R so a ringing “bell” sound alerts you to an incoming call. See page 42 for details.

CTCSS/DCS/EPCS OPERATION

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-8R, 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.

1.Press the key, then press the key. This provides a “Short-cut” to Set Mode Item 95: SQL TYPE.

2. Rotate the DIAL knob until “DCS” appears on the display; this activates the DCS Encoder/Decoder.

3.Press the key to save the new setting and exit to normal operation.

4.Press the key, then press the key. This provides a

“Short-cut” to Set Mode Item 26: DCS CODE.

5.Rotate the DIAL knob to select the desired DCS Code (a three-digit number). Ask the repeater owner/operator if you don’t know DCS Code; if you are working simplex, just set up the DCS Code to be the same as that used by your friends.

6.When you have made your selection, press the 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 incoming transmission. Switch the DCS off when you’re just tuning around the band!

CTCSS/DCS/EPCS 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 (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 key for one second to enter the Set Mode.

2.Rotate the DIAL knob to select Set Mode Item 27: DCS INVERSION.

3.Press the key briefly to enable adjustment of this Set

Mode Item.

4.Rotate the DIAL knob to select one of the following modes:

RX-NORMAL, TX-NORMAL:

Receive and transmit the Normal DCS Tone.

RX-INVERT, TX-NORMAL: Receive the Inverted DCS Tone and transmit the Normal DCS Tone.

RX-BOTH, TX-NORMAL:

Receive both Normal and Inverted DCS Tones and transmit the Normal DCS Tone.

RX-NORMAL, TX-INVERT:

Receive the Normal DCS Tone and transmit the Inverted DCS Tone.

5.When you have made your selection, press the PTT switch, 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 “R-N.T-N” (Receive and transmit the Normal DCS Tone) when done.

38

VX-8R OPERATING MANUAL

CTCSS/DCS/EPCS OPERATION

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 discussion). In the case of CTCSS,

TSQ” will appear on the display; in the case of DCS, “DCS” will appear on the display.

2.Press the key, then press the

key to recall the Set Mode Item 99: TONE FREQUENCY

when CTCSS is selected, or Menu Item 26: DCS CODE during DCS operation.

3.Press the key to enable adjustment of the selected Set Mode Item.

4.Press and hold in the key, the “TONE SEARCH” notation will appear, release the

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

5.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 key to lock in that tone/code, then press the 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 key during Tone Scanning to listen to the (muted) signal from the other station. When you release the key, Tone Scanning will resume after about a second.

Tone Scanning works either in the VFO or Memory modes.

CTCSS/DCS/EPCS OPERATION

EPCS (ENHANCED PAGING & CODE SQUELCH)

The VX-8R includes an Enhanced CTCSS tone encoder/decoder and a dedicated microprocessor providing paging and selective calling features. This allows you to place a call to a specific station (Paging), and to receive calls of your choice directed only to you (Code Squelch).

The paging and code squelch systems use two pairs of (alternately switched) CTCSS tones which are stored in the pager memories. Basically, your receiver remains silent until it receives the CTCSS tone pair that matches those stored in the Receiving Pager Memory. The squelch then opens so the caller is heard, and the paging ringer immediately sounds, if activated. When you close the PTT switch to transmit, the CTCSS tone pair 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.

STORING THE CTCSS TONE PAIRS FOR EPCS OPERATION

corresponds to the first tone of the CTCSS Tone Pair.

5. Press the key (“¾” icon moves to the right), then rotate the DIAL knob to set the CTCSS Tone number, which corresponds to the second tone of the CTCSS Tone Pair.

6. Press the PTT switch to save the new setting and exit to normal operation.

The VX-8R does not recognize the order of the 1st tone and the 2nd tone. In other words, for example, the VX-8R considers both CTCSS pairs “10, 35”

and “35, 10” to be identical.

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 key for 1/2 second.

3.Within five seconds of releasing the 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 Æ201 Æ301 …),

by pressing the

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 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 frequencies, and store them into additional memory locations, by repeating the above process.

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 56: MEMORY WRITE; see page 151.

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 54: MEMORY PROTECT. See page 151 for details. When the memory write protect is activated, the “PROTECT” notation appears on the display while a memory write operation is being performed.

3)You may change the duration time of the secondary function (press and holding the key) of the key via the Set Mode Item 36: FW KEY HOLD TIME; see page 148.

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.
