INSTALLATION This chapter describes the installation procedure for integrating the FT-2800M into a typi- cal amateur radio station. It is presumed that you possess technical knowledge and concep- tual 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

INSTALLATION SAFETY INFORMATION The FT-2800M 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 tap

INSTALLATION ANTENNA CONSIDERATION The FT-2800M is designed for use with antennas presenting an impedance of near 50 Ohms at all operating frequencies. The antenna (or a 50 Ohm dummy load) should be connected whenever the transceiver is turned on, to avoid damage that could otherwise result if trans- mission occurs accidentally without an antenna. Ensure that your antenna is designed to handle 65 Watts of transmitter power. Some mag- netic-mount mobile antennas, designed for use with hand-held t

INSTALLATION MOBILE INSTALLATION The FT-2800M must only be installed in vehicles having a 13.8 Volt negative ground elec- trical system. Mount the transceiver where the display, controls, and microphone are easily accessible, using the supplied MMB-83 mounting bracket. The transceiver may be installed in almost any location, but should not be positioned near a heating vent nor anywhere where it might interfere with driving (either visually or mechani- cally). Make sure to provide plenty of space

INSTALLATION MOBILE INSTALLATION Mobile Power Connections To minimize voltage drop and avoid blowing the vehicle’s fuses, connect the supplied DC power cable directly to the battery terminals. Do not attempt to defeat or bypass the DC cable’s fuse - it is there to protect you, your transceiver, and your vehicle’s electrical system. Warning! Never apply AC power to the power cable of the FT-2800M, nor DC voltage greater than 15.8 Volts. When replacing the fuse, only use a 15-A fuse. Failure to ob

INSTALLATION BASE STATION INSTALLATION The FT-2800M is ideal for base station use as well as in mobile installations. The FT- 2800M is specifically designed to integrate into your station easily, using the information to follow as a reference. AC Power Supplies Operation of the FT-2800M from an AC line requires a power source capable of providing at least 15 Amps continuously at 13.8 Volts DC. The FP-1023 and FP-1030A AC Power Supplies are available from your Yaesu dealer to satisfy these requir

FRONT PANEL CONTROLS & SWITCHES PWR MHz REV LOW D/MR VOL Knob This control adjusts the audio volume level. Clockwise rotation increases the volume level. SQL Knob This control is used to silence background noise on the receiver. It should be advanced clockwise just to the point where the noise is silenced (and the “ ” indicator on the display turns off), so as to provide the best sensitivity to weak signals.
