3FT-7100M Operating Manual
INSTALLATION
This chapter describes the installation procedure for integrating the FT-7100M 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-7100M.
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-7100M.
Avoid heating vents and window locations that could expose the transceiver to excessive
direct sunlight, especially in hot climates. The FT-7100M should not be used in an environment where the ambient temperature exceeds +140° F (+60° C).
4 FT-7100M Operating Manual
INSTALLATION
SAFETY INFORMATION
The FT-7100M 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
manually or using the auto-dial feature.
5FT-7100M Operating Manual
INSTALLATION
A NTENNA CONSIDERATIONS
The FT-7100M is designed for use with antennas presenting an impedance of near 50 Ohms
at all operating frequencies. The antenna (or a 50 W 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 50 Watts of transmitter power. Some magnetic-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).
Note that this transceiver is designed with wide frequency coverage in the VHF/UHF spectrum. For general listening, you may wish to have a broadband antenna such as a discone
available, as a directional antenna such as a Yagi will have degraded performance outside the
Amateur band for which it is designed.
Excellent reference texts and computer software are available for the design and optimization
of VHF and UHF 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-7100M 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 28 MHz may have a loss of 6 dB or more at 446 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).

For reference, the chart below shows approximate loss figures for typically-available coaxial
cables frequently used in VHF/UHF installations.

Loss figures are approximate; consult cable manufacturers’
catalogs for complete specifications.
In outdoor installations, be certain to weatherproof all connectors thoroughly, as water
entering a coaxial cable will cause losses to escalate rapidly, thus diminishing your communications effectiveness. The use of the shortest possible length of the highest quality coaxial cable that fits within your budget will ensure the best performance from your FT-
7100M.
7FT-7100M Operating Manual
INSTALLATION
MOBILE INSTALLA TION
The FT-7100M 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-36 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.
Transceiver Installation
Choose a mounting location with sufficient clearance for the transceiver. Using the mount-
r
ing bracket as a template for the mounting holes, use a 4.8 mm (3/16”) bit to drill the
mounting holes, and secure the mounting bracket with the supplied screws, washers,
and nuts (see diagram).
Position the transceiver in the bracket so that the holes in the side are aligned with those
r
in the bracket, and bolt the transceiver into place using the supplied short screws and flat
washers.
8 FT-7100M Operating Manual
INSTALLATION
MOBILE INSTALLA TION
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-7100M, nor DC voltage greater
than 15.8 Volts. When replacing the fuse, only use a 15-A fast-blow type. Failure to
observe these safety precautions will void the Limited Warranty on this product.
Before connecting the transceiver, check the voltage at the battery terminals while rev-
r
ving the engine. If the voltage exceeds 15 Volts, adjust the vehicle’s voltage regulator
before proceeding with installation.
Connect the RED power cable lead to the POSITIVE (+) battery terminal, and the BLACK
r
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.
Before connecting the cable to the transceiver, verify the voltage and polarity of the
r
voltage at the transceiver end of the DC cable using a DC voltmeter. Now connect the
transceiver to the DC cable.
Mobile Speakers
The optional SP-7 External Speaker includes its own swivel-type mounting bracket, and is
available from your Yaesu dealer.
Other external speakers may be used with the FT-7100M , if they present the specified 8-Ohm
impedance and are capable of handling the 2 Watts of audio output supplied by the FT-
7100M.
9FT-7100M Operating Manual
INSTALLATION
BASE STATION INSTALLATION
The FT-7100M is ideal for base station use as well as in mobile installations. The FT-7100M
is specifically designed to integrate into your station easily, using the information to follow
as a reference.
AC Power Supplies
Operation of the FT-7100M 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.
Packet Radio Terminal Node Controller (TNC)
The FT-7100M provides a convenient rear-panel DATA jack for easy connections to your
TNC. This connector is a standard mini-DIN connector. A pre-wired connector and cable
assembly option, model CT-39A, is available from your local Yaesu dealer.
The FT-7100M’s DATA jack connections are optimized for the data transmission and reception speed in use. In accordance with industry standards, the signal levels, impedances, and
bandwidths are significantly different on 9600 bps as opposed to 1200 bps. If your TNC does
not provide multiple lines to accommodate such optimization, you may still be able to utilize
your TNC, if it is designed for multiple-radio use, by connecting the TNC “Radio 1” port to
the 1200 bps lines on the FT-7100M, and the “Radio 2” port to the 9600 bps lines.
The pin connections of the Data connector are shown below.

INSTALLATION
BASE STATION INSTALLATION
Note that 9600 bps packet transmit-deviation adjustment is very critical to successful operation, and can only be accomplished using a calibrated deviation meter (such as that found on
an FM Service Monitor used in a communications service center). In most cases, the Packet
Data Input level (set via a potentiometer inside the TNC) must be adjusted to provide a
deviation of ±2.75 kHz (±0.25 kHz). Check with your packet node’s sysop if you have any
questions about the appropriate deviation level for your network. Note also that high throughput on 9600 bps frequently requires strong signals, so you may wish to consider the use of
a directional antenna such as a Yagi for communication with high-speed packet nodes.
The setting of the 1200 bps Packet Data Input level is much less critical than it is at 9600 bps,
and satisfactory adjustment to the optimum (±2.5 ~ ±3.5 kHz) deviation can usually be done
“by ear” by adjusting the TNC’s 1200 bps TX Audio Level potentiometer so that the outgoing packets (as monitored on a separate VHF or UHF receiver) are approximately the same
level as (A) the DTMF tones or (B) the 1750 Hz Burst tone produced using the microphone.
Typical connections to a TNC are shown below.
Finally, note that the (“
