INSTALLATION

This chapter describes the installation procedure for integrating the FT-2800M 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 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.

INSTALLATION TIPS

To ensure long life of the components, be certain to provide adequate ventilation around the cabinet of the FT-2800M.

Do not install the transceiver on top of another heat-generating device (such as a power supply or amplifier), and do not place equipment, books, or papers on top of the FT-2800M. Avoid heating vents and window locations that could expose the transceiver to excessive direct sunlight, especially in hot climates. The FT-2800M should not be used in an environment where the ambient temperature exceeds +140 °F (+60 °C).

FT-2800M OPERATING MANUAL

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 antenna installation.

Be certain to wrap any wire or cable splices thoroughly with insulating electrical tape, to prevent short circuits.

Do not route cables or wires through door jambs or other locations where, through wear and tear, they may become frayed and shorted to ground or to each other.

Do not stand in front of a directional antenna while you are transmitting into that antenna. Do not install a directional antenna in any location where humans or pets

may be walking in the main directional lobe of the antenna’s radiation pattern.

In mobile installations, it is preferable to mount your antenna on top of the roof of the vehicle, if feasible, so as to utilize the car body as a counterpoise for the antenna and

raise the radiation pattern as far away from passengers as possible.

During vehicular operation when stopped (in a parking lot, for example), make it a practice to switch to Low power if there are people walking nearby.

Never wear dual-earmuff headphones while driving a vehicle.

Do not attempt to drive your vehicle while making a telephone call on an autopatch using the DTMF microphone. Pull over to the side of the road, whether dialing manu-

ally or using the auto-dial feature.

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 transmission 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 transceivers, may not be capable of withstanding this power level. Consult the antenna manufacturer’s specification sheet for details.

Most all FM work is performed using vertical polarization. When installing a directional antenna such as a Yagi or Cubical Quad, be certain to orient it so as to produce vertical polarization, unless you are engaged in a special operating situation where horizontal polarization is used. In the case of a Yagi antenna, orient the elements vertically for vertical polarization; for a Cubical Quad, the feedpoint should be at the center of one of the vertical sides of the driven element (or at a side corner, in the case of a diamond-shaped Cubical Quad).

Excellent reference texts and computer software are available for the design and optimization of VHF antennas. Your dealer should be able to assist you with all aspects of your antenna installation requirements.

Use high-quality 50 Ohm coaxial cable for the lead-in to your FT-2800M 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 an 8-meter-long (25’ coaxial line with 1/2 dB of loss at 29 MHz may have a loss of 1.8 dB or more at 146 MHz; choose your coaxial cable carefully based on the installation location (mobile vs. base) and the overall length of the cable required (for very short runs of cable in a mobile installation, the smaller, more flexible cable types may be acceptable).

INSTALLATION

MOBILE INSTALLATION

The FT-2800M must only be installed in vehicles having a 13.8 Volt negative ground electrical 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 mechanically). Make sure to provide plenty of space on all sides of the transceiver so that air can flow freely around the radio’s case. Refer to the diagrams showing proper installation procedures.

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 observe these safety precautions will void the Limited Warranty on this product.

rBefore connecting the transceiver, check the voltage at the battery terminals while revving the engine. If the voltage exceeds 15 Volts, adjust the vehicle’s voltage regulator before proceeding with installation.

rConnect the RED power cable lead to the POSITIVE (+) battery terminal, and the BLACK power cable lead to the NEGATIVE () terminal. If you need to extend the power cable, use #12 AWG or larger insulated, stranded copper wire. Solder the splice connections carefully, and wrap the connections thoroughly with insulating electrical tape.

rBefore connecting the cable to the transceiver, verify the voltage and polarity of the voltage at the transceiver end of the DC cable using a DC voltmeter. Now connect the transceiver to the DC cable.

INSTALLATION

BASE STATION INSTALLATION

The FT-2800M is ideal for base station use as well as in mobile installations. The FT2800M 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 requirements. Other wellregulated power supplies may be used, as well, if they meet the above voltage and current specifications.

Use the DC power cable supplied with your transceiver for making power connections to the power supply. Connect the RED power cable lead to the POSITIVE (+) power supply terminal, and connect the BLACK power cable lead to the NEGATIVE () power supply terminal.

Base Station Feet

The supplied Base Station Feet allow the transceiver to be tilted upward for better viewing.

To install the Base Station Feet, remove the two screws affixing the front side of the bottom cover , then install the Base Station Feet using these screws.

BASIC OPERATION

Hi! I’m R. F. Radio, and I’ll be helping you along as you learn the many features of the FT-2800M. I know you’re anxious to get on the air, but I encourage you to read “Basic Operation” section of this manual as thoroughly as possible, so you’ll get the

most out of this fantastic new transceiver. Now. . .let’s get operating!

 

TURNING THE TRANSCEIVER ON AND OFF

 

1.

To turn the transceiver on, press and hold in the PWR key

 

 

for one second.

 

 

When you turn on the FT-2800M, the current DC supply

 

 

voltage is indicated on the LCD for 2 seconds. After this

 

 

interval, the display will switch its normal indication of the

PWR MHz

 

 

 

operating frequency.

 

2.

To turn the transceiver off, again press and hold in the PWR key for one second.

ADJUSTING THE AUDIO VOLUME LEVEL

Rotate the VOL control to adjust the receiver volume. Clockwise rotation increases the audio output level.

PWR MHz

ADJUSTING THE SQUELCH SETTING

Rotate the SQL control just to the point where the noise is silenced and the “” indicator on the display turns off. If the SQL control is set further clockwise, sensitivity to weak signals is reduced.

PWR MHz

A special “RF Squelch” feature is provided on this radio. This feature allows you to set the squelch so that only signals exceeding a certain S-meter level will open the squelch. See page 20 for details

FREQUENCY NAVIGATION

1) Tuning Dial

Rotating the DIAL knob allows tuning in the pre-programmed steps. Clockwise rotation of the DIAL knob causes the FT-2800M to be tuned toward a higher frequency, while counter-clock- wise rotation will lower the operating frequency.

Press the [MHz(SET)] key momentarily, then rotate the DIAL knob, to change the frequency steps to 1 MHz per step. This feature is extremely useful for making rapid frequency excursions over the wide tuning range of the FT-2800M. Instead of pressing the [MHz(SET)] button, you may also press the [A] key on the Microphone’s keypad to engage tuning in 1 MHz steps.

14

FT-2800M OPERATING MANUAL

BASIC OPERATION

FREQUENCY NAVIGATION

2) Direct Keypad Frequency Entry

The keypad of the MH-48A6J DTMF Microphone may be used for direct entry of the operating frequency.

To enter a frequency from the MH-48A6J keypad, just press the numbered digits in the proper sequence. There is no “decimal point” key on the MH-48A6J keypad. However, there is a short-cut for frequencies ending in zero: press the [#] key after the last non-zero digit.

Examples: To enter 146.520 MHz, press [1] à [4] à [6] à [5] à [2] à [0] To enter 146.000 MHz, press [1] à [4] à [6] à [#]

If you cannot get the radio to accept the frequency entry, it is possible that the channel steps are set to an incompatible value (e.g. if you have 25 kHz steps set, you cannot set a frequency of 146.520 MHz). See page 19 to learn how to change the

channel step size.

3) Scanning

From the VFO mode, press the microphone’s [UP]/[DWN] keys momentarily to initiate scanning toward a higheror lower frequency, respectively. The FT-2800M will stop when it receives a signal strong enough to break through the squelch threshold. The FT-2800M will then hold on that frequency according to the setting of the “Resume” mode (Menu “23 SCAN)”; see page 34).

If you wish to reverse the direction of the scan (i.e. toward a lower frequency, instead of a higher frequency), just rotate the DIAL knob one click in the counter-clockwise direction while the FT-2800M is scanning. The scanning direction will be reversed. To revert to scanning toward a higher frequency once more, rotate the DIAL knob one click clockwise.

Press the [UP]/[DWN] keys again to cancel scanning. You may also press the PTT button momentarily; scanning will stop, but you will not transmit until you release the PTT button, and press it again.

If you have enabled the “Severe Weather Alert” feature, you will occasionally notice “WX” channels interspersed with the regular channels you are scanning. This

is normal, because your radio is constantly monitoring for weather alerts. See page 17.
