INSTALLATION This chapter describes the installation procedure for integrating the FT-857 into a typical amateur radio station. It is presumed that you possess technical knowledge and conceptual understanding consistent with your status as a licensed radio amateur. Please take some extra time to make certain that the important safety and technical requirements detailed in this chapter are followed closely. PRELIMINARY INSPECTION Inspect the transceiver visually immediately upon opening the packi

INSTALLATION SAFETY INFORMATION The FT-857 is an electrical apparatus, as well as a generator of RF (Radio Frequency) energy, and you should exercise all safety precautions as are appropriate for this type of device. These safety tips apply to any device installed in a well-designed amateur radio station. Never allow unsupervised children to play in the vicinity of your transceiver or an- tenna installation. Be certain to wrap any wire or cable splices thoroughly with insulating electrical tape,

INSTALLATION INSTALLING THE MICROPHONE AND FRONT PANEL 1. Insert the microphone’s plug into the recessed jack on the transceiver, as shown in the illustration. 2. You may position the microphone cable so as to cause it to exit from the side or the bottom of the transceiver. Just route the cable into the appropriate channel provided, as shown in the illustration. 3. Connect the Control cable between the Front Panel and Transceiver Body. 4. Install the Front Panel by sliding it into the position s

INSTALLATION POWER CONNECTIONS The DC power connector for the FT-857 must only be connected to a DC source providing 13.8 Volts DC (±15%), and capable of at least 22 Amperes of current. Always observe proper polarity when making DC connections: The Red DC power lead connects to the Positive (+) DC terminal; and the Black DC power lead connects to the Negative (–) DC terminal. In mobile installations, noise pickup may be minimized by connecting the DC cable directly to your vehicle’s battery, rat

INSTALLATION POWER CONNECTIONS Tips for Successful Mobile Installations: r 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 charging volt- age to 14 Volts or lower. r Route the DC cable as far away from the ignition cables as possible. r If the DC cable is not long enough, use #12 AWG (minimum) stra

INSTALLATION GROUNDING The provision of an effective ground system is important in any successful communications station. A good ground system can contribute to station efficiency in a number of ways: r It can minimize the possibility of electrical shock to the operator. r 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. r It can minimize the po

INSTALLATION GROUNDING Base Station Earth Grounding Typically, the ground connection consists of one or more copper-clad steel rods, driven into the ground. If multiple ground rods are used, they should be configured in a “V” configura- tion, 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 we

INSTALLATION ANTENNA CONSIDERATIONS The antenna systems connected to your FT-857 transceiver are, of course, critically impor- tant in ensuring successful communications. The FT-857 is designed for use with any an- tenna system providing a 50 W resistive impedance at the desired operating frequency. While minor excursions from the 50 W specification are of no consequence, the power amplifier’s protection circuitry will begin to reduce the power output of there is more than a 50% diver- gence fro

INSTALLATION ANTENNA CONSIDERATIONS rest of the vehicle’s body, using a heavy braid bonded securely at both ends, to ensure that as much counterpoise as possible is secured. In portable operation, be sure to lay out radials (or otherwise construct a n image plane for the vertical monopole); it is not adequate simply to connect a vertical radiating element to the rear panel Antenna jack of this transceiver, with- out providing a suitable counterpoise.

INSTALLATION ANTENNA CONSIDERATIONS Do not allow disconnected cables to touch the case of your FT-857 transceiver or accesso- ries, 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

INSTALLATION ELECTROMAGNETIC COMPATIBILITY If this transceiver is used with, or in the vicinity of, a computer or computer-driven accesso- ries, 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 from the computer. Computer-generated RFI is usually a result of inad- equate shielding of the computer’s cabinet or I/O and peripheral connections. While com- pu

INSTALLATION LINEAR AMPLIFIER INTERFACING The FT-857 provides the switching and drive-control lines required for easy interfacing to most all commonly-available amplifiers sold today. These include: r The Antenna Jacks (“HF/50MHz” and “144/430MHz”); r A T/R control line (open circuit on RX, closure to ground on TX); and r A negative-going ALC jack (control voltage range: 0V to –4V DC). r When interfacing to the VL-1000 Solid State 1 KW Linear Amplifier, the optional CT- 58 Interface Cable provid

INSTALLATION LINEAR AMPLIFIER INTERFACING The “TX GND” T/R control line is a transistor “open collector” circuit, capable of handling positive amplifier relay coil voltages of up to +50V DC and current of up to 400 mA. If you plan on using multiple linear amplifiers for different bands, you must provide external band- switching of the “TX GND” relay control line from the CAT/LINEAR jack. Important Note! Do not exceed the maximum voltage or current ratings for the “TX GND” line at the CAT/LINEAR

INSTALLATION ( ) RECEIVER ACCESSORIES TAPE RECORDER ETC. Connection of a tape recorder or other such receiver accessory is DATA OUT 1200bps easily accomplished by using the DATA jack’s Data Out (1200 bps) GND terminal (Pin 5) and Ground (Pin 2). The audio output is fixed at DATA 100 mV, with an impedance of 600 W. ADJUSTING THE FRONT FEET The two front feet of the transceiver allow the transceiver to be tilted upward for better viewing. Simply fold both feet forward to raise the front of the tra
