INSTALLATION
Safety Precautions
Before proceeding with installation of the VX-1700 transceiver, please read and observe all safety and operating instructions. Consult with qualified installation or service personnel should any questions arise regarding these important safety tips.

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 lightning strike. Install appropriate lightning arrestors in the antenna lead-in and rotator cable (if used) according to the arrestors 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-1700 transceiver 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 instantly 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.

Power Connections
The power connector for the VX-1700 must only be connected to a DC source providing 13.8 Volts DC (15 %), and capable of at least 22 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-1700 transceiver, but the wiring configuration of the other manufacturers 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 surplus/discarded RG-213 type cable is ideal). The lead-in cable should be as short as possible. Do not use gas lines as a ground connection!

Heat and Ventilation

To ensure long life of the components, be certain to provide adequate ventilation around the cabinet of the VX1700. 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.

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 transceiver 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-1700 Transceiver and its accessories.

INSTALLATION
Electromagnetic Compatibility and RF Exposure
If this transceiver is used with or in the vicinity of a computer or computer-driven accessories, you may need to experiment with grounding and/or radio frequency interference (RFI) suppression devices (such as ferrite cores) to minimize interference to your communications caused by energy leakage from the computer. Although there is negligible radio frequency (RF) leakage from the VX-1700 transceiver itself, its antenna system should be located as far away from humans and animals as practicable, 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 carton, so as to preserve the evidence of shipping damage for insurance purposes.

POWER REQUIREMENTS
DC Power Connections
The VX-1700 transceiver is designed for operation from 13.8 Volts DC, negative ground, with the DC source being capable of providing 25 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 polarity 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 transceiver, 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

AND

BASIC INSTALLATION

(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 vehicles voltage regulator should be adjusted to reduce the charging 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-1700 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 switching transients.

MOBILE MOUNTING
The optional MMB-89 Mobile Mounting Bracket allows quick insertion and removal of the VX-1700 transceiver from the vehicle. Complete installation instructions are provided with the bracket. provide memory of antenna matching settings sufficient for all channels on Memory Bank 1. In marine applications, the FC-40 is also ideal for the use with a backstay antenna or marine mobile whip. 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 manufacturers 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 Yaesu model 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.

Mobile Antenna Considerations

The VX-1700 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 amplifiers protection circuitry 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 Yaesu YA-007FG or similar mobile whip antenna may be used in conjunction with the Yaesu FC40 External Antenna Tuner. The FC-40 is designed 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.

MOBILE MOUNTING
Mobile Station Grounding
Although satisfactory grounding in most installations will be achieved via the DC cables negative lead and the antenna systems coaxial cable shield, it may be necessary, in some installations, to provide a direct ground connection at the mounting location of the transceiver. Due to unexpected resonances which may naturally occur in any location, improper 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-1700 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-1700 transceiver to the vehicle or vessels 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.

BASE STATION INSTALLATION
DC Power Connections
For base station installations, Yaesu recommends the use of the Model FP-1030A AC Power Supply. The FP1030A 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-1700, but the 13.8 V DC input voltage, 25 Ampere current capability, and DC cable polarity guidelines described previously must be strictly followed. If you are connecting the FP-1030A with the VX-1700 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 transceiver. Your warranty does not cover damage caused by application of AC, reversed polarity 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-1700 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-1700 transceiver!

BASE STATION INSTALLATION
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 impedance of the antenna system utilized with the VX1700 is as close as practicable to the specified 50-Ohm impedance value, and that mechanical and electrical component integrity are maintained at all times. For wide frequency range applications, Vertex Standards Model YA-30 Broadband Dipole Antenna may be ideal for your communication requirements. Covering an operating frequency range of 1.8-30 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 complete 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-1700 transceiver 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 support structure such as a tower. The height of the horizontal 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 particular frequency. For example, at 6 MHz a horizontal dipole 10 meters high (33 feet) will provide excellent 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 dipole at a height of 10 meters could, ionospheric propagation conditions permitting, be expected to provide outstanding performance over the same 3000 km distance.

INSTALLATION
BASE STATION INSTALLATION
Excellent reference texts and computer software are available for the design and optimization 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 VX1700 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 justperceptible 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 coaxial cables frequently used in HF installations.

Base Station Grounding

The VX-1700 HF transceiver, like any other HF communications apparatus, requires an effective ground system for maximum electrical safety and best communications effectiveness. 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 devices 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. Typically, the ground connection consists of one or more 2.4m (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 socalled 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.

OPERATION
STARTUP PROCEDURES
Be certain that all power supply, antenna, ground, microphone, and other accessory connections have been properly accomplished. Rotate the VOL and SQL knobs fully counter-clockwise. Turn on the transceiver by press and holding in the POWER Switch. The LCD display will become illuminated.

RECEPTION
Rotate the VOL knob for a comfortable listening level on the incoming signals or noise present on the speaker. When no signal is present on the channel, rotate the SQL knob clockwise until the background noise is just silenced. Unless you are responsible for listening for very weak signals (very near the background noise), silencing the receiver using the circuitry is usually preferable in most application. Rotate the CH Selector knob to select the desired Memory Channel within the selected Memory Bank. Remember that there are a total of five Memory Banks, so if you do not find a particular channel, it may have been stored in a different Memory Bank. The microphone [UP] and [DWN] buttons may also be used to select the Memory Channel. Pressing the [UP] or [DWN] button momentarily will cause the Memory Channel to increment or decrement one step, respectively. Pressing and holding the [UP] or [DWN] button in for 1/2 second will initiate upward or downward scanning on the Memory Channels, respectively. Releasing the [UP] or [DWN] button halts the scan. If you want to select the operating channel from a different Memory Channel Bank, press the front panels [S(UP)] or [T(DWN)] button to select the Memory Channel Bank you want before selecting the operating channel. When a signal strong enough to override the squelch threshold is received, the incoming signal will be heard in the speaker, and icon will be illuminated. When the incoming signal disappears, the icon will disappear, although the icon will still be illuminated. When a signal is being received, the S/PO meter will become illuminated according to the incoming signal strength. You may use this S/PO meter reading to compare communications path effectiveness on different channels, or to assist with optimum antenna rotation, if a directional antenna is being used. Should you experience interference from impulse noise, such as that from a power line or a vehicle, press the keypads [2(NB)] (Noise Blanker) key to reduce the noise level. When the noise blanker is activated, the icon will be illuminated. Press the [2(NB)] key again to disable the noise blanker.

OPERATION
RECEPTION
If the station you are listening to should drift or otherwise be unclear (the voice may sound too highpitched or too low-pitched), pressing the [P1] or [P3] key may improve the sound of the incoming signal. The [P1]/[P3] key function does not affect your transmission frequency; only the receive frequency is being adjusted. When the receiving frequency is higher than displayed frequency, the S icon will appear to the right of the frequency display. Similarly, when the receiving frequency is lower than displayed frequency, the T icon will appear to the right of the frequency display. Press and hold in both [P1] and [P3] keys for one second to reset the offset. If the LCD display is too bright, press the keypads [0(DIM)] key to reduce the display brightness. Press the [0(DIM)] key again return to the LCD display to nominal brightness level. To turn the internal speaker (or external speaker, if used) off, press the [P4] key. Press the [P4] key again to restore the speaker audio.

TRANSMISSION
For Voice transmission, close the PTT (Push To Talk) switch on the microphone; the transmitter will now be activated (note that the icon will be illuminated on the LCD display). 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 icon will be again illuminated, and the icon will go out). For CW (Morse Code telegraphy) in the A1A mode, begin sending using your telegraph key or electronic keyer. The VX-1700 will automatically be placed in the transmit 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 sending. For Data transmission (including Morse Code telegraphy using a TNC (Terminal Node Controller) and keyboard, or similar computer-driven data transmission devices), transmit/receive control is exercised by the software which accompanies the data transmission equipment in use. See the Users 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 (5 or 6 segments illuminated on the Power Output Bar Graph) if long periods of continuous transmission are anticipated.

Front Panel Locking

To prevent inadvertent changing of the channel frequency or other front panel parameters, press the [P2] key on the front panel. All keys, and the Channel Selector knob, will locked out of the operational command capability except for the POWER switch, the [DOWN] and [UP] buttons, and the [P2] key itself. The icon will appear on the display. Press the [P2] key again to release the front panel to normal operation.

Antenna Tuning Procedures

When the optional FC-30 or FC-40 External Antenna Tuner is installed, it is activated on each channel automatically. If the icon appears at the upper right corner on the LCD display while transmitting, the antenna system may require retuning. Use the following procedure. Be certain that all connections to the FC-30/-40 have been properly made. With the appropriate channel selected via the Main Dial, press the keypads [ 3 ( TUNER )] key. The icon on the LCD Display will blink, and the VX-1700 will transmit for a short time. Thereafter, the transceiver will return to the receive mode, and the icon will now be illuminated constantly. The FC-30/-40s microprocessor-based circuitry includes memory sufficient to retain 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.

OPERATION
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, Channel #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, one of two things will happen: If the VX-1700 is in the Carrier Drop mode, the transceiver will hold on memory channel 1-001 until the transmission ceases. The transceiver will continue to hold for ten seconds after the transmission ends, in case the other station decides to resume transmitting. After the three second delay, Dual Watch will resume, with your original operating channel (not memory channel 1-001) being restored to the Main Display. If the VX-1700 is set to the Time Delay mode, 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). Dual Watch operation is simple to use. Follow these steps: First, set the desired Resume mode for Dual Watch. Usually, this will be Carrier Drop, which will not allow the transceiver to move off memory channel 101 if someone is still transmitting. To do this, press the [F] key followed by the [8(DW)] key, then rotate the CH Selector knob until CARR is shown in the LCD display. If you prefer the Time Delay mode, rotate the CH Selector knob until TIME is displayed. Now press the [8(DW)] key again to return to the normal display.

Adjust the SQL control so that the icon disappears and the receiver is silenced. Press the [8(DW)] key to activate Dual Watch. After four seconds, the transceiver will switch over to memory channel 1-001, and will stay there for 1/2 second, thereafter returning to your original channel. If a call is received on memory channel 1-001 during Dual Watch operation, the transceiver will lock onto that channel, then resume in accordance with the Resume mode selected previously. Press the [8(DW)] key again to disable the Dual Watch feature. 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.

OPERATION
ENCRYPTED TRANSMISSION/RECEPTION (REQUIRES AFTER-MARKET ENCRYPTION MODULE)
If the transceivers you (and others in your communication group) are using are equipped with an after-market Encryption Module, the Encryption mode may be activated by pressing the [ENCR] key. The icon will become illuminated. To de-activate encryption, press the [ENCR] key again. 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 transceivers encryption mode. Pressing the [ENCR] key 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 [ENCR] key on the other stations transceiver, then revert to encrypted operation immediately by pressing the [ENCR] key on your transceiver.
