SAFETY PRECAUTIONS
Before proceeding with installation of the VX-1400 transceiver, please read and observe
all safety and operating instructions. Consult with qualified installation or service person-
nel should any questions arise regarding these important safety tips.
Power Connections
The power connector for the VX-1400 must only be connected to a DC source providing
13.8 Volts DC (±15 %), and capable of at least 23 Amperes of current. Do not connect this
apparatus to any other DC voltage, and never connect the DC power cable to an AC
source of any kind. Always observe proper polarity when making DC connections. Our
Limited Warranty does not cover damage caused by improper power connections.
Note that other manufacturers may use the same type of DC power connector as does your
VX-1400 transceiver, but the wiring configuration of the other manufacturer’s plug may
be different from that specified for your transceiver. Serious damage can be caused if
improper DC connections are made; consult with a qualified service technician when in
doubt.
Grounding for Electrical Safety
Connect the rear panel ground lug to a good earth ground. For best performance, such a
ground should consist of one or more ground rods 2.6 m (8 feet) long, connected to the
transceiver via a low-inductance cable such as a heavy braided wire (the shield from sur-
plus/discarded RG-213 type cable is ideal). The lead-in cable should be as short as pos-
sible.
Do not use gas lines as a ground connection!
Electrical Shock Prevention
Be certain that all station wiring is properly insulated so as to prevent short-circuits which
could damage this transceiver and/or accessories connected to it. Be sure to protect power
cables from damage due to abrasion by ensuring that they cannot be walked upon nor
crushed under rolling chairs, etc. Never route power cables near sharp metallic edges
which might cut through protective insulation.
Never spill liquids into this transceiver, and do not drop metallic objects into the trans-
ceiver enclosure. Electrical shock may result when you attempt to remove the object.
Unsupervised children should be kept away from any electrical apparatus such as the VX-
1400 Transceiver and its accessories.
INSTALLATION
Page 10
VX-1400 OPERATING MANUAL8
Antenna Precautions
Always locate antennas such that they can never come in contact with outdoor power lines
in the event of a catastrophic antenna support or power line support structure failure.
Ground the support structure adequately, so as to dissipate energy absorbed during a light-
ning strike. Install appropriate lightning arrestors in the antenna lead-in and rotator cable
(if used) according to the arrestor’s instructions.
In the event of an approaching electrical storm, disconnect all antenna lead-in, rotator
cables, and power cables completely from your station if the storm is not immediately in
your area. Do not allow disconnected cables to touch the case of your VX-1400 trans-
ceiver or accessories, as lightning can easily jump from the cable to the circuitry of your
transceiver via the case, causing irreparable damage. If a lightning storm is in progress in
your immediate area, do not attempt to disconnect the cables, as you could be killed in-
stantly if lightning should strike your antenna structure or a nearby power line.
If a vertical antenna is utilized, be certain that humans and/or pets and farm animals are
kept away both from the radiating element (to prevent electrical shock and RF exposure
danger) and the ground system, in the event of an electrical storm. The buried radials of a
ground-mounted vertical antenna can carry lethal voltages outward from the center of the
antenna in the event of a direct lightning strike.
Heat and Ventilation
To ensure long life of the components, be certain to provide adequate ventilation around
the cabinet of the VX-1400. The cooling system of the transceiver must be free to draw
cool air in from the bottom of the transceiver and expel warm air from the rear of the
transceiver.
Do not install the transceiver on top of another heat-generating device (such as a linear
amplifier), and do not place equipment, books, or papers on top of the transceiver. Place
the transceiver on a hard, flat, stable surface. Avoid heating vents and window locations
that could expose the transceiver to excessive direct sunlight, especially in hot climates.

Electromagnetic Compatibility and RF Exposure
If this transceiver is used with or in the vicinity of a computer or computer-driven acces-
sories, you may need to experiment with grounding and/or radio frequency interference
(RFI) suppression devices (such as ferrite cores) to minimize interference to your commu-
nications caused by energy leakage from the computer.
Although there is negligible radio frequency (RF) leakage from the VX-1400 transceiver
itself, its antenna system should be located as far away from humans and animals as prac-
ticable, so as to avoid the possibility of shock due to accidental contact with the antenna or
excessive long-term exposure to RF energy.
Preliminary Inspection
Inspect the transceiver visually immediately upon opening the packing carton. Confirm
that all controls and switches work freely, and inspect the cabinet for any damage. Gently
shake the transceiver to verify that no internal components have been shaken loose due to
rough handling during shipping.
If any evidence of damage is discovered, document it thoroughly and contact the shipping
company (or your local dealer, if the unit was purchased over-the-counter) so as to get
instructions regarding the prompt resolution of the damage situation. Be certain to save
the shipping carton, especially if there are any punctures or other evidence of damage
incurred during shipping; if it is necessary to return the unit for service or replacement,
use the original packing materials but put the entire package inside another packing car-
ton, so as to preserve the evidence of shipping damage for insurance purposes.

POWER REQUIREMENTS AND BASIC INSTALLATION
DC Power Connections
The VX-1400 transceiver is designed for operation from 13.8 Volts DC, negative ground,
with the DC source being capable of providing 23 Amperes of continuous current.
For mobile applications, the fused (25-A) DC cable supplied with this transceiver may be
used for making the power connections. Be absolutely certain to observe the proper polar-
ity when making power connections:
The RED DC power lead connects to the Positive (+) DC terminal; and the BLACK DC
power lead connects to the Negative (–) DC terminal.
To minimize noise pickup, and to provide the best input voltage stability for your trans-
ceiver, we recommend you connect the DC cable directly to the vehicle battery, rather
than to the ignition or accessory circuitry. Route the DC cable as far away from ignition
cables as possible, and cut off any extra cable (from the battery end) to minimize voltage
drop. If the DC cable is not long enough, use #12 AWG (minimum) stranded, insulated
wire to extend it. Be absolutely certain to solder the connections at the splice securely, and
provide ample insulation for the soldered splice (heat shrink tubing plus black electrical
tape work well).

Use the following procedure to connect the DC cable:
Before connecting the DC cable to the battery, measure the voltage across the battery
terminals with the engine running fast enough to show a charge. If the voltage is
above 15 Volts, the vehicle’s voltage regulator should be adjusted to reduce the charg-
ing voltage below 14 Volts.
With the radio end of the cable disconnected, connect the RED cable lead to the
POSITIVE battery terminal, and the BLACK cable lead to the NEGATIVE battery
terminal. Make certain that the battery terminal connections are tight, and remember
to check them periodically for signs of loosening and/or corrosion.
Make sure the POWER switch on the VX-1400 transceiver is off, and plug the DC
cable into the INPUT jack on the rear panel of the transceiver.
CAUTION! In mobile installations, check to ensure that the transceiver POWER switch is
turned off whenever starting or stopping the engine, to avoid potential damage from switch-
ing transients.

MOBILE MOUNTING
The optional MMB-92 Mobile Mounting Bracket allows quick insertion and removal of
the VX-1400 transceiver from the vehicle. Complete installation instructions are pro-
vided with the bracket.
Mobile Antenna Considerations
The VX-1400 transceiver is designed for use with any antenna system providing a 50-
Ohm resistive impedance at the desired operating frequency. While minor excursions from
the 50-Ohm specification are of no consequence, the power amplifier’s protection cir-
cuitry will begin to reduce the power output if there is more than a 50% divergence from
the specified impedance (less than 25 Ohms or greater than 100 Ohms, corresponding to
a Standing Wave Ratio (SWR) of 2.0:1). Compliance with this specification critically
depends on the range of frequencies on which operation will take place, and the design of
the antenna(s) in use.
If your mobile or marine operation requires wide frequency coverage, the optional YA-
007FG (Frequency range is 7 MHz - 30 MHz) or similar mobile whip antenna may be
used in conjunction with the optional FC-40 External Antenna Tuner. The FC-40 is de-
signed to accommodate a wide variety of whip impedances at the operating frequency,
converting these to the desired 50 ohm impedance via a sophisticated microprocessor-
controlled impedance matching circuit. The FC-40 and VX-1400 provide memory of
antenna matching settings sufficient for all channels on Memory Bank 1. In marine appli-
cations, the FC-40 is also ideal for the use with a “backstay” antenna or marine mobile
whip.
INSTALLATION
Install the ferrite core
as close to connector
as possible.
Wrap the ends of
the waterproof cap
with sealing tape to
protect against
moisture ingress.
IMPORTANT
When connecting optional
equipment, you must turn off
the transceiver.
Page 15
13VX-1400 OPERATING MANUAL
The FC-40 should be located at or near the base of the antenna, so as to minimize losses
and stray radiation. The short lead-in wire from the whip must be securely bonded both to
the FC-40 and the antenna (whip or wire), and the FC-40 must be securely bonded to the
vehicle or vessel ground system, which will act as a counterpoise for the FC-40 and
antenna radiating element. Be sure to weatherproof all outdoor connections thoroughly,
especially in maritime environments.
Complete the installation by connecting the RF coaxial cable and FC-40 control cable as
shown in the pictorial below. Complete installation instructions are found in the FC-40
Instruction Manual; follow the manufacturer’s installation instructions when using a whip
antenna other than the YA-007FG.
For extending the operating frequency range of an antenna fed with coaxial cable, the
optional FC-30 Antenna Tuner may also be used. The impedance matching range of the
FC-30 is from 17 Ohms to 150 Ohms. Interconnection guidelines may be found in the
Operating Manual for the FC-30.

VX-1400 OPERATING MANUAL14
Mobile Station Grounding
Although satisfactory grounding in most installations will be achieved via the DC cable’s
negative lead and the antenna system’s coaxial cable shield, it may be necessary, in some
installations, to provide a direct ground connection at the mounting location of the trans-
ceiver. Due to unexpected resonances which may naturally occur in any location, im-
proper communication system performance may result from insufficient grounding. These
symptoms may include: RF feedback (resulting in distortion of your transmitted signal),
unintended scanning, blinking or blanking of the frequency display, or loss of memory.
Note that these conditions may occur in any communications installation. The VX-1400
includes extensive filtering designed to minimize the chance of such problems; however,
random currents set up by insufficient RF grounding can nullify such filtering. Bonding
the rear panel GND terminal of the VX-1400 transceiver to the vehicle or vessel’s ground
system should clear up any such difficulties.
Vertex Standard does not recommend the use of “on glass” mobile antennas unless the
shield of the coaxial cable is securely grounded near the feedpoint of the antenna. Such
antennas frequently are responsible for the ground-related difficulties described above.
INSTALLATION
MOBILE MOUNTING
Page 17
15VX-1400 OPERATING MANUAL
BASE STATION INSTALLATION
DC Power Connections
For base station installations, Vertex Standard recommends the use of the optional FP-
1030A AC Power Supply. The FP-1030A provides a regulated 13.8 V DC supply at up to
25-Ampere.
Other models of DC power supplies may be used with the VX-1400, but the 13.8 V DC
input voltage, 23-Ampere current capability, and DC cable polarity guidelines described
previously must be strictly followed.
If you are connecting the FP-1030A with the VX-1400 for the first time, before
connecting power check the label in the rear of the FP-1030A which indicates the
AC mains voltage for which the supply is currently set.
CAUTION! Permanent damage can result if improper supply voltage is applied to this trans-
ceiver. Your warranty does not cover damage caused by application of AC, reversed polar-
ity DC, or DC outside of the specified range of 13.8 V ±15%. If using a power supply
other than the FP-1030A, ensure that the DC supply connector to the transceiver matches
the VX-1400 wiring configuration. Other manufacturers may utilize power supplies with
a physically matched connector that is wired differently; this will cause serious damage to
the VX-1400 transceiver!

Base Station Antenna Considerations
As with mobile or maritime installations, antenna performance is critical to base station
communications system effectiveness. Every effort must be made to ensure that the im-
pedance of the antenna system utilized with the VX-1400 is as close as practicable to the
specified 50-Ohm impedance value, and that mechanical and electrical component integ-
rity are maintained at all times.
For wide frequency range applications, Vertex Standard’s Model YA-30 Broadband Di-
pole Antenna may be ideal for your communication requirements. Covering an operating
frequency range of 1.6-30 MHz, the YA-30 eliminates the need for multiple antennas
which might otherwise be required for equivalent frequency coverage.
The type of antenna required for a particular communications distance will vary. A com-
plete discussion of this topic is beyond the range of this manual; however, a few general
guidelines will be offered herewith.
Any antenna to be installed should be free of nearby obstructions which might interfere
with its radiation pattern. The antenna, its support structure, and its cables must never be
installed in such a manner that would allow them to contact with power or telephone lines
in the event of a catastrophic windstorm or other cause of major failure. An adequate
safety is usually provided by keeping the antenna and its support structure 1.5 times the
height of the support plus the length of any antenna or guy wires attached to the support.
When installing a balanced antenna such as a dipole, remember that the VX-1400 trans-
ceiver is designed for use with an (unbalanced) coaxial feedline. Always use a balun or
other balancing device so as to ensure proper antenna system performance.
Vertical antennas usually provide excellent coverage beyond about 1000 km (600 miles),
but very poor coverage at closer distances. Horizontal antennas are frequently better for
shorter distances, but they may require a stout sup-
port structure such as a tower. The height of the hori-
zontal antenna, and the nature of the ground below it,
have a profound impact on the favored launch angle
for the main radiation lobe from the antenna at a par-
ticular frequency. For example, at 6 MHz a horizon-
tal dipole 10 meters high (33 feet) will provide excel-
lent local coverage out to about 500 km (300 miles);
however, at the same frequency the dipole would have
to be much higher (perhaps 50 meters or 165 feet) for
satisfactory communication over a range of 3000 km
(1800 miles). On the other hand, at 26 MHz the same

expected to provide outstanding performance over the same 3000 km distance.
Excellent reference texts and computer software are available for the design and optimi-
zation of HF antennas. Your dealer or installer should be able to assist you with all aspects
of your antenna installation.
Use high-quality coaxial cable for the lead-in to your VX-1400 transceiver. All efforts at
providing an efficient antenna system will be wasted if poor quality, lossy coaxial cable is
used. Losses in coaxial lines increase as the frequency increases, so a coaxial line with 0.5
dB of loss at 6 MHz may have 2 dB of loss at 26 MHz (1 dB is a just-perceptible decrease
in signal strength). As a general rule, smaller-diameter coaxial cables tend to have higher
losses than larger-diameter cables, although the precise differences depend critically on
the cable construction, materials, and the quality of the connectors used on the cable. See
the cable manufacturers’ specifications for details.
For reference, the chart below shows approximate loss figures for typically-available co-
axial cables frequently used in HF installations.

Base Station Grounding
The VX-1400 HF transceiver, like any other HF communications apparatus, requires an
effective ground system for maximum electrical safety and best communications effec-
tiveness. A good ground system can contribute to station efficiency in a number of ways.
It can minimize the possibility of electrical shock to the operator.
It can minimize RF currents flowing on the shield of the coaxial cable and the chassis
of the transceiver which may cause interference to nearby home entertainment de-
vices or laboratory test equipment.
It can minimize the possibility of erratic transceiver operation caused by RF feedback
or improper current flow through logic devices.
An effective earth ground system may take several forms; for a more complete discussion,
see an appropriate RF engineering text. The information presented below is intended only
as a guideline.
INSTALLATION
BASE STATION INSTALLATION
Page 21
19VX-1400 OPERATING MANUAL
Typically, the ground connection consists of one or more 2.4 m (8’) copper-clad steel
rods, driven into the ground. If multiple ground rods are used, they should be configured
in a “V” configuration, and bonded together at the apex of the V which is nearest the
station location. Use a heavy, braided cable (such as the discarded shield from type RG-
213 coaxial cable) and strong cable clamps to secure the braided cables to the ground
rods. Be sure to weatherproof the connections to ensure many years of reliable service.
Use the same type of heavy, braided cable for the connections to the station ground bus
(described below).
Inside the station, a common ground bus consisting of a solid copper pipe of at least 25mm
(1”) diameter should be used. Another ideal ground bus may consist of a wide copper plate
(single-sided circuit board material is ideal) secured to the bottom of the operating desk.
Grounding connections from individual devices such as transceivers, power supplies, and
data communications devices should be made directly to the ground bus using a heavy,
braided cable.
Do not make ground connections from one electrical device to another, and thence to the
ground bus. This so-called “Daisy Chain” grounding technique may nullify any attempt at
effective radio frequency grounding. See the drawings below for examples of proper and
improper ground connections.
Inspect the ground system - inside the station as well as outside - on a regular basis so as
to ensure maximum performance and safety.

TRANSMISSION
For Voice transmission, close the PTT (Push To Talk) switch on the microphone; the
transmitter will now be activated and the TX/BUSY indicator glows red. Hold the
microphone about 1 inch (25 mm) from your mouth, and speak into the front of the
microphone in a normal voice level. Release the PTT switch to return to the receive
mode (the red TX/BUSY indicator will disappeared).
For CW (Morse Code telegraphy) in the A1A mode, begin sending using your tele-
graph key or electronic keyer. The VX-1400 will automatically be placed in the trans-
mit mode when you start to send, and will revert to the receive mode when you stop
sending. As you send, a “Sidetone” audio generator allows you to monitor your send-
ing.
For Data transmission (including Morse Code telegraphy using a TNC (Terminal Node
Controller) and keyboard, or similar computer-driven data transmission devices), trans-
mit/receive control is exercised by the software which accompanies the data trans-
mission equipment in use. See the User’s Manual for your terminal equipment for
operating instructions. Remember to follow the maximum power output guidelines
during continuous-duty operation such as RTTY (Radio Teletype) in the J2B mode.
Adjust the TX Audio level from the TNC for a maximum of 50 Watts of power output
(4 segments illuminated on the Power Output Bar Graph) if long periods of continu-
ous transmission are anticipated.
Note: The CW and Data transmission requires optional CT-139 Accessory Cable.
Speech Processor
The VX-1400 radio has a built-in speech processor. This speech processor is used in the
SSB mode.
The speech processor increases SSB average transmit power output. This will produce a
louder signal on the receiving radio and provide better readability of the receive signal.
This also expands the communication range in the SSB mode.
When programming with CE111 software, in the Mic Gain setting, the following optional
settings are available:
LOW: Speech Processor is OFF
Normal: Speech Processor is ON (Default)
High: Speech Processor is ON
When the Speech Processor setting is required; please select “Normal” or “High” in the
CE111 Mic Gain setting.
If you need wider service coverage and better readability of the signal, the “High” selec-
tion would be recommended.

Antenna Tuning Procedures
When the optional FC-30 or FC-40 External Antenna Tuner is installed, it is activated on
each channel automatically.
Be certain that all connections to the FC-30/-40 have been properly made.
Select the appropriate channel with the []/[] button.
Press the [TUNER] button (the [PROGRAMMABLE] button which assigned “TUNER”
function: the factory default is the [P1] button). The two arrows of “ ” icon on the
LCD display will blink, and the VX-1400 will transmit for a short time. Thereafter,
the transceiver will return to the receive mode, and the “ ” icon will now be illumi-
nated constantly.
The FC-30/-40’s microprocessor-based circuitry includes memory sufficient to re-
tain 100 (for FC-30, 200 for FC-40) antenna tuning settings in memory. This will
greatly reduce frequency change time. If you utilize more than 100 or 200 operating
channels that are widely removed in frequency, the new tuning settings will be over-
written on a first-in, first-out basis.
IMPORTANT NOTE
If the impedance encountered by the FC-30/-40 exceeds 2:1, the “ ” icon will
blink, and the microprocessor will not retain the tuning data for that frequency, as
the FC-30/-40 presumes that you will want to adjust or repair your antenna sys-
tem so as to correct the high SWR condition. Similarly, when the temperature of
the inside of the transceiver’s case becomes higher, the “ ” icon will also blink.
Stop the transmission and cool down the transceiver for few minutes.

DUAL WATCH
The Dual Watch feature allows the user or dispatcher to operate on one channel while
periodically making a brief check of Memory Channel “1-001” (Memory Bank #1, Chan-
nel #1). The Dual Watch feature can be engaged so long as there is frequency and mode
data written into memory channel “1-001”.
Every four seconds, the transceiver will automatically switch over to memory channel “1-
001”. If a station is transmitting on memory channel “1-001”, the transceiver will hold on
memory channel “1-001” for five seconds, then Dual watch operation will resume (irre-
spective of the transmit/receive status of any stations on memory channel “1-001”).
Dual Watch operation is simple to use. Follow these steps:
Adjust the squelch circuit so that the green TX/BUSY indicator disappears and the
receiver is silenced.
Press the [DW] button (the [PROGRAMMABLE] button which assigned “Dual Watch”
function) to activate Dual Watch. After four seconds, the transceiver will switch over
to memory channel “1-001,” and will stay there for 1/2 seconds, thereafter returning
to your original channel. The “ ” icon will become illuminated while the Dual
Watch feature is activated.
If a call is received on memory channel “1-001” during Dual Watch operation, the
transceiver will hold on memory channel “1-001” for five seconds, then Dual watch
operation will resume (irrespective of the transmit/receive status of any stations on
memory channel “1-001”). The “ ” icon will blinks while receiving the memory
channel “1-001”.
Press the [DW] button again to disable the Dual Watch feature. The “ ” icon disap-
pears and operation will revert to your original operating frequency.
Note that your main operating channel can be changed during Dual Watch operation,
but you cannot change channels while memory channel “1-001” is being checked for
activity.

tion). The “ ” icon will become illuminated.
To de-activate encryption, press the [ENCRP] button.
If the signals of all the other stations in your communications group have a severely
distorted or “scrambled” sound, you may have accidentally de-activated your
transceiver’s encryption mode. Pressing the [ENCRP] button may allow recovery.
However, if only one station in your communications group sounds distorted or
“scrambled,” it is possible that the encryption mode of that transceiver may have been
accidentally turned off. Either the dispatcher or you may advise the other station by
switching your encryption off and calling the other station in the non-encrypted mode.
Remember that your transmissions will be sent in a non-encrypted format, and will
thus not be secure; limit your discussion to a brief advisory regarding the [ENCRP
]
button on the other station’s transceiver, then revert to encrypted operation immedi-
ately by pressing the [ENCRP] button on your transceiver.
