Installation
This chapter describes the installation procedure for integrating the FT-90R 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-90R.
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-90R. Avoid heating vents and window locations that could expose the
transceiver to excessive direct sunlight, especially in hot climates. The FT-90R
should not be used in an environment where the ambient temperature exceeds
+60º C (140º F).
10
FT-90R OPERATING MANUAL
Installation
Safety Information
The FT-90R 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.
Do not allow unsupervised children to play in the vicinity of your trans-
０
ceiver or antenna installation.
Be certain to wrap any wire or cable splices thoroughly with insulating
electrical tape, to prevent short circuits.
０
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
０
each other.
Do not allow anyone to stand in front of a directional antenna while you
are transmitting into that antenna, especially on UHF. Do not install a di-
０
rectional 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
０
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 the “MID2” or “LOW” power options if there
０
are people walking nearby.
Never wear dual-earmuff headphones while driving a vehicle.
FT-90R OPERATING MANUAL
11
Antenna Considerations
Installation
The FT-90R is designed for use with antennas presenting an impedance of near 50
Ω at all operating frequencies. The antenna (or a 50 Ω 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 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 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.
Note that this transceiver is designed with wide frequency coverage in the VHF
and UHF spectra. For general listening, you may wish to have a broadband antenna such as a discone available, because a directional antenna such as a Yagi
will have degraded performance outside the Amateur bands.
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 Ω coaxial cable for the lead-in to your FT-90R 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 only ½ dB of loss at 28 MHz
may have a loss of 2 dB or more at 440 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).
12
FT-90R OPERATING MANUAL
Installation
For reference, the chart below shows approximate loss figures for typically-available coaxial cables frequently used in VHF/UHF installations.
Loss in dB per 30 m (100 feet) for Selected 50 Ω Coaxial Cables
(Assumes 50Ω Input/Output Terminations)
Cable Type Loss: 144 MHz Loss: 440 MHz

Belden® 9913 1.5 2.7
1/2" Hardline 1.0 1.8
7/8" Hardline 0.7 1.3
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-90R.
FT-90R OPERATING MANUAL

Mobile Installation
Installation
The FT-90R must only be installed in vehicles having a negative ground electrical system. Mount the transceiver where the display, controls, and microphone are
easily accessible, using the supplied MMB-68 mounting bracket. The transceiver
may be installed in any position, 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 at the rear of the transceiver so that
air can flow freely through the heatsink. Refer to the diagrams showing proper
installation procedures.
Transceiver Installation
r Choose a mounting location with sufficient clearance for the transceiver, plus
space for ventilation around the heat sink.
Using the mounting 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).
r Position the transceiver in the bracket so that the holes in the side are aligned
with those in the bracket, and bolt the transceiver into place using the supplied
short screws and flat washers.
14
FT-90R OPERATING MANUAL
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-90R, nor DC voltage
greater than 15.8 Volts. When replacing the fuse, only use a 15-A fastblow type. Failure to observe these safety precautions will void the Limited Warranty on this product.
r Before 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.
r Connect 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.
r Before 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.
Mobile Speakers
The optional SP-7 or MLS-100 External Speakers include their own swivel-type
mounting brackets, and are available from your Yaesu dealer.
Other external speakers may be used with the FT-90R, if they present the specified 4-16 Ω impedance and are capable of handling the 2 Watts of audio output
supplied by the FT-90R.
FT-90R OPERATING MANUAL

Base Station Installation
Installation
The FT-90R is ideal for base station use as well as in mobile installations. The FT90R is specifically designed to integrate into your station easily, using the infor-
mation to follow as a reference.
AC Power Supplies
Operation of the FT-90R from an AC line requires a power source capable of
providing at least 10 Amps continuously at 13.8 Volts DC. The FP-1023A, FP1025A, and FP-1030A AC Power Supplies are available from your Yaesu dealer
to satisfy these requirements. Other well-regulated 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 NEGA-
TIVE (-) power supply terminal.
Packet Radio Terminal Node Controller (TNC)
The extremely compact size of the FT-90R does not allow the inclusion of a
dedicated packet interfacing jack. However, all connections required for either
1200 bps or 9600 bps packet operation are provided, either on the front or rear
