6、d 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 shou

7、ld be as short as possible. 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 trans- ceiver and/or accessories connected to it. Be sure to pro- tect power cables fr

8、om damage due to abrasion by ensur- ing 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 insula- tion. Never spill liquids into this transceiver, and do not drop metallic objects into the tran

9、sceiver enclosure. Electrical shock may result when you attempt to remove the object. Unsupervised children should be kept away from any elec- trical apparatus such as the VX-1700 Transceiver and its accessories. INSTALLATION Antenna Precautions Always locate antennas such that they can never come i

10、n contact with outdoor power lines in the event of a cata- strophic 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 rotat

11、or cable (if used) according to the arrestors instruc- tions. In the event of an approaching electrical storm, discon- nect all antenna lead-in, rotator cables, and power cables completely from your station if the storm is not immedi- ately in your area. Do not allow disconnected cables to touch the

12、 case of your VX-1700 transceiver or accesso- ries, as lightning can easily jump from the cable to the circuitry of your transceiver via the case, causing irrepa- rable damage. If a lightning storm is in progress in your immediate area, do not attempt to disconnect the cables, as you could be killed

13、 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 radi- ating element (to prevent electrical shock and RF expo- sure danger) and the ground system, i

14、n 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 pro- vide adequate ventila

15、tion around the cabinet of the VX- 1700. 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-gen- erating device (such as a linear amplifie

16、r), and do not place equipment, books, or papers on top of the transceiver. Place the transceiver on a hard, flat, stable surface. Avoid heat- ing vents and window locations that could expose the trans- ceiver to excessive direct sunlight, especially in hot cli- mates. Page 6VX-1700 OPERATING MANUAL

17、 Electromagnetic Compatibility and RF Exposure If this transceiver is used with or in the vicinity of a com- puter or computer-driven accessories, you may need to experiment with grounding and/or radio frequency inter- ference (RFI) suppression devices (such as ferrite cores) to minimize interferenc

18、e 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

19、accidental contact with the antenna or excessive long-term exposure to RF energy. Preliminary Inspection Inspect the transceiver visually immediately upon open- ing the packing carton. Confirm that all controls and switches work freely, and inspect the cabinet for any dam- age. Gently shake the tran

20、sceiver to verify that no internal components have been shaken loose due to rough han- dling during shipping. If any evidence of damage is discovered, document it thor- oughly and contact the shipping company (or your local dealer, if the unit was purchased over-the-counter) so as to get instruction

21、s 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 re- turn the unit for service or replacement, use the original packing materials but pu

22、t the entire package inside an- other packing carton, so as to preserve the evidence of shipping damage for insurance purposes. INSTALLATION Page 7VX-1700 OPERATING MANUAL POWER REQUIREMENTS AND BASIC INSTALLATION DC Power Connections The VX-1700 transceiver is designed for operation from 13.8 Volts

23、 DC, negative ground, with the DC source being capable of providing 20 Amperes of continuous current. For mobile applications, the fused (25-A) DC cable sup- plied with this transceiver may be used for making the power connections. Be absolutely certain to observe the proper polarity when making pow

24、er 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 v

25、ehicle 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 volt- age drop. If the DC cable is not long enough, use #12 AWG (minimum) stranded, insulated wire to ex

26、tend it. Be abso- lutely certain to solder the connections at the splice se- curely, 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, m

27、ea- sure 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 regula- tor should be adjusted to reduce the charging voltage below 14 Volts. ? With the radio end of the cable disconnected, connect the RED

28、 cable lead to the POSITIVE battery termi- nal, and the BLACK cable lead to the NEGATIVE bat- tery terminal. Make certain that the battery terminal connections are tight, and remember to check them pe- riodically for signs of loosening and/or corrosion. ? Make sure the POWER switch on the VX-1700 tr

29、ans- ceiver 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 start- ing or stopping the engine, to avoid potential damage from switching transients. 12V B

Complete installation instructions are provided wi

31、th the bracket. 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 cir

32、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 criti- cally depends on the range of frequencies on

33、 which opera- tion 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 FC- 40 External Antenna Tuner. The FC-40 is designed to ac- co

34、mmodate a wide variety of whip impedances at the op- erating frequency, converting these to the desired 50 ohm impedance via a sophisticated microprocessor-controlled impedance matching circuit. The FC-40 and VX-1700 provide memory of antenna matching settings sufficient for all channels on Memory B

35、ank 1. In marine applica- tions, 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

36、 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 weather- proof all outdoor connections thoroughly, especially in maritime environments. Comple

37、te 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 in- stallation instructions when using a whip antenna other than the YA-007FG. For ex

38、tending 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. Interconnec- tion guidelines may be found in the Operating Manual for the FC-30. VX-1700 FC-30 INST

39、ALLATION Page 9VX-1700 OPERATING MANUAL Mobile Station Grounding Although satisfactory grounding in most installations will be achieved via the DC cables negative lead and the an- tenna systems coaxial cable shield, it may be necessary, in some installations, to provide a direct ground connec- tion

40、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), uninten

41、ded scanning, blinking or blanking of the frequency display, or loss of memory. Note that these conditions may occur in any communi- cations installation. The VX-1700 includes extensive fil- tering designed to minimize the chance of such problems; however, random currents set up by insufficient RF g

42、round- ing 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 difficul- ties. Vertex Standard does not recommend the use of “on glass” mobile antennas unless the shield of the coaxial cable is se

43、curely grounded near the feedpoint of the antenna. Such antennas frequently are responsible for the ground-re- lated difficulties described above. MOBILE MOUNTING INSTALLATION Page 10VX-1700 OPERATING MANUAL BASE STATION INSTALLATION DC Power Connections For base station installations, Yaesu recomme

44、nds the use of the Model 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-1700, but the 13.8 V DC input voltage, 20-Ampere current capability, and DC cable polarity guidelines de- scribed previ

45、ously 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

46、sup- ply voltage is applied to this transceiver. Your warranty does not cover damage caused by application of AC, re- versed 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 matche

47、s 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!

48、-1700 REDBLACK FUSE: 25A INSTALLATION Page 11VX-1700 OPERATING MANUAL Base Station Antenna Considerations As with mobile or maritime installations, antenna per- formance is critical to base station communications sys- tem effectiveness. Every effort must be made to ensure that the impedance of the a

49、ntenna system utilized with the VX-1700 is as close as practicable to the specified 50-Ohm impedance value, and that mechanical and elec- trical 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 oper- ating frequency range of 1.6 -30 MHz, the YA-30 elimi- nates the need for multiple antennas which might other- wise be required for equivalent frequency coverage.
