POWER CONNECTIONS
The DC power connector for the FT-100 must only be connected to a DC source providing
13.8 Volts DC (±IO%), 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.
For base station installations, Yaesu recommends the use of the FP-I023, FP-I025, or FP-
1030A AC power supplies. Other models of power supplies may be used with the FT -100,
but the 13.8V DC input voltage, 22-Ampere current capability, and DC cable polarity
guidelines described above must be strictly followed.
Note that other manufacturers may use the same type
of DC power connections as does your
FT-IOO transceiver, but the wiring configuration of the other manufacturer's plug may be
different from that specified for your transceiver. Serious damage can be caused
if improper
DC connections are made; consult with a qualified service technician when in doubt.
In mobile installations, noise pickup may be minimized by connecting the DC cable di-
rectly to your vehicle's battery, rather than to the ignition switch or "accessory" circuitry.
Direct connection to the battery also provides the best voltage stability.
Tips for Successful Mobile Installations:
o 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
voltage to
14 Volts or lower.
o Route the DC cable as far away from the ignition cables as possible.
o If the DC cable is not long enough, use #12 AWG (minimum) stranded, insulated wire
to extend it. Be certain to solder the connections at the splice securely, and provide
ample insulation for the soldered splice (heat shrink tubing plus black electrical tape
work well).
o Check the battery terminal connections frequently to be sure they are tight and not
corroded.
,--------------- Caution ---------------,
Permanent damage can result if improper supply voltage, or reverse-polarity volt-
age,
is applied to the FT-IOO. The Limited Warranty on this transceiver does not
cover damage caused by application
of AC voltage, reversed polarity DC, or DC
voltage outside the specified range of 13 .8V ± I0%. Never attempt to connect the
FT-JOO to a 24 Volt battery system.

When replacing fuses, be certain to use a fuse of the proper rating. The FT-100
requires a 25A fast-blow fuse.

GROUNDING
The provision of an effective ground system is important in any successful communica-
tions station. A
good ground system can contribute to station efficiency in a number of
ways:
D It can minimize the possibility of electrical shock to the operator.
D 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 entertain-
ment devices
or laboratory test equipment.
D It can minimize the possibility of erratic transceiver operation caused by RF feed-
back or improper current flow through logic devices.
An effective earth ground system may take several forms; for a more complete discussion,
see an appropriate RF engineering text. The information presented below
is intended only
as a guideline.
Inspect the ground system -inside the station as well as outside -on a regular basis so as
to ensure maximum performance and safety.
Mobile Station Grounding
Although satisfactory grounding in most installations will be achieved via the DC cable's
negative lead and the antenna system's coaxial cable shield,
it is often recommended that
you provide a direct ground connection to the vehicle chassis at the mounting location
of
the transceiver (installation using the MMB-48 Mobile Bracket will accomplish this, if the
MMB-48 itself
is mounted to the vehicle's chassis). Due to unexpected resonances which
may naturally occur
in any location, improper communication system performance may
result from insufficient grounding. These symptoms may include:
D RF feedback (resulting in distortion on your transmitted signal);
D Unintended frequency change;
D Blinking or blanking of the frequency display;
D Noise pickUp; and/or
D Loss of memory.
Note that these conditions may occur
in any communications installation. The FT-JOO
includes extensive filtering designed to minimize the chance of such problems; however,
random currents set up by insufficient
RF grounding can nullity such filtering. Bonding the
rear panel Ground lug
of the FT-J 00 transceiver to the vehicle or vessel's ground system
should clear up any such difficulties.
Yaesu does not recommend the use of "on glass" mobile antennas unless the shield of the
coaxial cable
is securely grounded near the feedpoint of the antenna. Such antennas fre-
quently are responsible for the ground-related difficulties described above.
10 FT-100
MICRO MOBILE OPERATING MANUAL

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"
configuration, and bonded together at the apex of the V which is nearest the station loca-
tion. 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
weatherproofthe connections to ensure many years
of reliable service. Use the same type
ofheavy, braided cable for the connections to the station ground bus (described below).
Do not use gas line pipes in an attempt to provide a ground connection! To do so creates
a serious risk
of explosion!!
Inside the station, a common ground bus consisting
of a copper pipe of at least 25 mm (1")
diameter should be used. An alternative station ground bus may consist of a wide copper
plate (single-sided circuit board material
is ideal) secured to the bottom of the operating
desk. Grounding connections from individual devices such as transceivers, power sup-
plies, and data communications devices should be made directly to the ground bus using a
heavy, braided cable.
Do not make ground connections from one electrical device to another, and thence to the
ground bus. This so-called "Daisy Chain" grounding technique may nullify any attempt at
effective radio frequency grounding. See the drawings below for examples
of proper and
improper ground connections.
If your coaxial cable does not connect directly to the station
ground bus, you may connect a ground cable to the FT-J 00 using one ofthe mounting bolts
from the MMB-48 Mobile Bracket.

ANTENNA CONSIDERATIONS
The antenna systems connected to your FT-I00 transceiver are, of course, critically impor-
tant
in ensuring successful communications. The FT-IOO is designed for use with any an-
tenna system providing a
son resistive impedance at the desired operating frequency.
While minor excursions from the son 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% divergence from the specified impedance (less than
33n orgreater than 75n, corre-
sponding to a Standing Wave Ratio (SWR)
of 1.5: 1).
Two antenna connector "pigtails" are provided on the rear panel of the FT-100. The "AN-
TENNA 1" connection is used for HF and 50 MHz, while the "ANTENNA 2" connector
is used for 144 MHz and 430 MHz.
Guidelines for successful base and mobile station installations are shown below.
Mobile AntennaInstallations
Mobile antennas for the HF bands, with the possible exception of those designed for 28
MHz, display very high "Q" due to the fact that they must be physically shortened, then
resonated using a loading coil. Additional system bandwidth may be realized using the
Yaesu
FC-20 Automatic Antenna Tuner, which will present a son impedance to your
transceiver on the
1.8 ~ 50 MHz bands so long as the SWR on the coaxial line connected
to the
FC-20 is below 3: 1.
On the VHF and UHF bands, coaxial line losses increase so rapidly in the presence of
SWR that we recommend that all impedance matching to son be performed at the antenna
feedpoint.
Yaesu's Active-Tuned Antenna System (ATAS-100)
is a unique HFIVHF/UHF mobile
antenna system, which provides automatic tuning when used with the
FT-IOO. See page 62
for full details on the ATAS-100.
For VHF/UHF weak-signal (CW/SSB) operation, remember that the antenna polarization
standard for these modes
is horizontal, not vertical, so you must use a loop or otherwise
horizontally-polarized antenna so as to avoid cross-polarization loss
of signal strength
(which can be 20 dB
or more!). On HF, signals propagated via the ionosphere develop
mixed polarizations, so antenna selection may be made strictly on mechanical consider-
ations; vertical antennas are almost always utilized on HF for this reason.
12 FT-100 MICRO MOBILE OPERATING MANUAL

Installation
ANTENNA CONSIDERATIONS
Base Station Antenna Installations
When installing a "balanced" antenna such as a Vagi or dipole, remember that the FT-100
is designed for use with an (unbalanced) coaxial feedline. Always use a balun or other
balancing device so as to ensure proper antenna system performance.
Use high-quality son coaxial cable for the lead-in to your FT-100 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 a coaxial line with
0.5
dB ofloss at 7 MHz may have 6 dB ofloss at 432 MHz (thereby consuming 75% of
your transceiver's power output!). As a general rule, smaller-diameter coaxial cables tend
to have higher losses than larger-diameter cables, although the precise differences depend
on the cable construction, materials, and the quality of the connectors used with the cable.
See the cable manufacturers' specifications for details.
For reference, the chart below shows approximate
loss figures for typically- available coaxial cables
frequently used
in HF installations.

Installation
ANTENNA CONSIDERATIONS
Always locate antennas such that they can never come in contact with outdoor power lines
in the event of a catastrophic support or power-pole structural failure. Ground your anten-
nas' support structure(s) adequately, so
as to dissipate energy absorbed during a lightning
strike. Install appropriate lightning arrestors
in the antenna coaxial cables (and rotator
cables,
if rotary antennas are used).
In the event of an approaching electrical storm, disconnect all antenna
lead-in, rotator cables, and power cables completely from your station
if
the storm is not immediately in your area. Do not allow disconnected
cables to touch the case
of your FT-IOO transceiver or accessories, as
lightning can easily jump from the cable to the circuitry
of your trans-
ceiver 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 certain that humans and/or pets and
farm animals are kept away both from the radiating element (to prevent
electrical shock and RF exposure danger)
and the ground system (in the
event
of an electrical storm). The buried radials of a ground-mounted
vertical antenna can carry lethal voltages outward from the center
of the
antenna
in the event of a direct lightning strike.

This transceiver is capable of power output in excess of 50 Watts, so customers in the
United States may be required to demonstrate compliance with Federal Communications
Commission (FCC) regulations concerning maximum permissible exposure to radio fre-
quency energy. Compliance
is based on the actual power output used, feedline loss, an-
tenna type and height, and other factors which can only be evaluated as a system.
Information regarding these regulations may be available from your Dealer, your local
radio club, from the FCC directly (press releases and other information can be found on the
FCC's site on the World Wide
Web at <http://www.fcc.gov>), or from the American Radio
Relay League, Inc. (225 Main St., Newington CT 06111 or <http://www.arrl.org>).
Although there is negligible radio frequency (RF) leakage from the FT
-100 transceiver
itself, its antenna system should be located as far away from humans and animals as prac-
ticable, so
as to avoid the possibility of shock due to accidental contact with the antenna or
excessive long-term exposure to
RF energy. During mobile operation, do not transmit if
someone
is standing adjacent to your antenna, and use the lowest power possible.
Never stand
in front of an antenna (during testing or operation) when RF power is applied,
especially in the case of 430 MHz directional arrays. The 20 Watt power output supplied
by the FT
-100, combined with the directivity of a beam antenna, can cause immediate
heating
of human or animal tissues, and may cause other undesirable medical effects.

ELECTROMAGNETIC COMPATIBILITY
If this transceiver is used with, or in the vicinity of, a computer or computer-driven acces-
sories, you may need to experiment with grounding and/or Radio Frequency Interference
(RFI) suppression devices (such as ferrite cores) to minimize interference to
your commu-
nications caused by energy from the computer. Computer-generated RFI
is usually a result
of inadequate shielding of the computer's cabinet or 110 and peripheral connections. While
computer equipment may "comply" with RF emission standards, this does not ensure that
sensitive Amateur Radio receivers like the FT
-100 will not experience interference from
the device!
Be certain to use only shielded cables for TNC-to-Transceiver connections. You may need
to install AC line filters on the power cord(s) of the suspected equipment, and decoupling
ferrite toroidal chokes may be required on interconnecting patch/data cables. As a last
resort, you can try installing additional shielding within the computer's case, using appro-
priate conductive mesh or conductive shielding tape. Especially check "RF holes" where
plastic
is used for cabinet front panels.
For further information, consult amateur radio reference guides and publications relating
to RFI suppression techniques.
HEAT AND VENTILATION
To ensure long life of the components, be certain to provide adequate ventilation around
the cabinet of the FT-IOO. The cooling system of the transceiver must be free to draw cool
air
in from the side of the transceiver and expel warm air from the rear of the transceiver.
Do not install the transceiver on top of another heat-generating device (such as a linear
amplifier), and do not place equipment, books, or papers on top
of the transceiver. Place
the transceiver on a hard, flat, stable surface. Avoid heating vents and window locations
that could expose the transceiver to excessive direct sunlight, especially
in hot climates.

ACCESSORY INTERFACING
The FT-100 may be connected to a wide variety of accessories in your amateur station,
whether you're at home or away. Due to the compact size
of the FT-IOO, many of the rear-
panel connectors are used for more than one purpose. The sections to follow will describe
the interfacing procedures.
LinearAmplifierInterfacing
The FT-100 provides the switching and drive-control lines required for easy interfacing to
most all commonly-available amplifiers sold today.
These include:
o The Antenna Cable Pigtails (#1 and #2);
o A T/R control line (open circuit on RX, closure to ground on TX); and
o A negative-going ALC jack (control voltage range: OV to -4 V DC).
o When interfacing to the VL-I000 Solid State 1 KW Linear Amplifier, the optional
CT -58 Interface Cable provides for easy interconnection.
The rear-panel ACC
jack is a miniature stereo type, which accepts ALC control voltage
input on the tip connection, and T/R control on the ring connection. The main shaft
is used
for the ground connection.
Typical amplifier interface circuits are shown below.
Note that some amplifiers, particularly VHF or UHF "brick" amplifiers, offer two methods
ofT/R switching: application of +13V or a closure to ground.
Be sure to configure your amplifier so that
it switches via a closure to ground, as provided
by your FT
-100. Alternatively, many of these amplifiers use "RF Sensing" to control their
relays;
if yours is not in this category, you may then use the T/R control line from the ring
of the ACC jack for control of your HF linear amplifier, if desired.
The 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 rnA. If you plan on
using multiple linear amplifiers for different bands, you must provide external band-switch-
ing
of the "LIN Tx" relay control line from the "ring" connection of the ACC jack
18
Important Note!
Do not exceed the maximum voltage or current ratings for the ACC jack. This jack
is not compatible with negative DC voltages, nor AC voltages of any magnitude.
Most amplifier control relay systems require only low DC voltage/current switch-
ing capability (typically, +12V DC at 25
~ 75 rnA), and the switching transistor in
the FT-100 will easily accommodate such amplifiers.
