POWER CONNECTIONS
The FT-897D is designed use from (1) an external DC power source, (2) internal battery (requires optional FNB-78 Ni-MH
battery pack), or (3) AC power source (requires optional FP-30 Internal AC Power Supply).
External DC power source operation
INSTALLATION
The DC power connector for the FT-897D must only be
connected to a DC source providing 13.8 Volts DC (±15%),
and capable of at least 22 Amperes of current. Always ob-
serve 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.
In mobile installations, noise pickup may be minimized by
connecting the DC cable directly to your vehicle’s battery,
rather than to the ignition switch or “accessory” circuitry.
Direct connection to the battery also provides the best volt-
age stability.
Tips for Successful Mobile Installations:
ÌBefore 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.
ÌRoute the DC cable as far away from the ignition cables
as possible.
ÌIf the DC cable is not long enough, use #12 AWG (mini-
mum) stranded, insulated wire to extend it. Be certain to
solder the connections at the splice securely, and pro-
vide ample insulation for the soldered splice (heat shrink
tubing plus black electrical tape work well).
ÌCheck the battery terminal connections frequently to be
sure they are tight and not corroded.
ÌWhen operating with the vehicle turned off, or operating
from a stand-alone car battery (in a camp site, etc.), be
mindful of the minimum operating voltage (11.73 Volts)
for the FT-897D. If the battery is not charged sufficiently
to maintain at least 11¾ Volts at the radio, erratic opera-
tion or shut-down may occur.
Caution
Permanent damage can result if improper supply volt-
age, or reverse-polarity voltage, is applied to the FT-
897D. The Limited Warranty on this transceiver does
not cover damage caused by application of AC voltage,
reversed polarity DC, or DC voltage outside the speci-
fied range of 13.8V ±15%. Never attempt to connect
the FT-897D to a 24 Volt battery system.
When replacing fuses, be certain to use a fuse of the
proper rating. The FT-897D requires a 25A fast-blow
fuse.

INSTALLATION
GROUNDING
The provision of an effective ground system is important in
any successful communications station. A good ground sys-
tem can contribute to station efficiency in a number of ways:
ÌIt can minimize the possibility of electrical shock to the
operator.
ÌIt 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 entertainment
devices or laboratory test equipment.
ÌIt can minimize the possibility of erratic transceiver op-
eration caused by RF feedback 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 engi-
neering 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 per-
formance and safety.
Mobile Station Grounding
Although satisfactory grounding in most installations will
be achieved via the DC cable’s negative lead and the an-
tenna 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 (installa-
tion using the optional MMB-80 Mounting Bracket will ac-
complish this, if the MMB-80 itself is mounted to the
vehicle’s chassis). Due to unexpected resonance which may
naturally occur in any location, improper communication
system performance may result from insufficient ground-
ing. These symptoms may include:
ÌRF feedback (resulting in distortion on your transmitted
signal);
ÌUnintended frequency change;
ÌBlinking or blanking of the frequency display;
ÌNoise pickup; and/or
Ì
ons may occur in any communica-
tions installation. The FT-897D includes extensive filtering
designed to minimize the chance of such problems; how-
ever, random currents set up by insufficient RF grounding
can nullify such filtering. Bonding the rear panel Ground
lug of the FT-897D transceiver to the vehicle or vessel’s
ground system should clear up any such difficulties.
Vertex Standard does not recommend the use of “on glass”
mobile antennas unless the shield of the coaxial cable is se-
curely grounded near the feedpoint of the antenna. Such
antennas frequently are responsible for the ground-related
difficulties described above.
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 location. Use a heavy, braided
cable (such as the discarded shield from type RG-213 co-
axial cable) and strong cable clamps to secure the braided
cables to the ground rods. Be sure to weatherproof the con-
nections to ensure many years of reliable service. Use the
same type of heavy, 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 cop-
per 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 di-
rectly 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 connec-
tions. If your coaxial cable does not connect directly to the
station ground bus, you may connect a ground cable to the
Ground lug on the FT-897D rear panel.

ANTENNA CONSIDERATIONS
The antenna systems connected to your FT-897D transceiver
are, of course, critically important in ensuring successful
communications. The FT-897D is designed for use with any
antenna system providing a 50 Ωresistive impedance at the
desired operating frequency. While minor excursions from
the 50 Ωspecification 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 speci-
fied impedance (less than 33 Ωor greater than 75 Ω, corre-
sponding to a Standing Wave Ratio (SWR) of 1.5:1).
Two antenna jacks are provided on the rear panel of the FT-
897D. The “HF/50 MHz ANT” jack is used for HF and 50
MHz, while the “144/430 MHz ANT” jack is used for 144
MHz and 430 MHz.
Guidelines for successful base and mobile station installa-
tions are shown below.
Mobile Antenna Installations
Mobile antennas for the HF bands, with the possible excep-
tion 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-30 Automatic Antenna
Tuner, which will present a 50 Ωimpedance to your trans-
ceiver on the 1.8 ~ 50 MHz bands so long as the SWR on
the coaxial line connected to the FC-30 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 50 Ωbe performed at the antenna
feedpoint.
Yaesu’s Active-Tuned Antenna System (ATAS-100/-120)
is a unique HF/VHF/UHF mobile antenna system, which
provides automatic tuning when used with the FT-897D.
See page 39 for full details on the ATAS-100/-120.
For VHF/UHF weak-signal (CW/SSB) operation, remem-
ber 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-polar-
ization 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 considerations; vertical antennas are almost al-
ways utilized on HF for this reason.
Base Station Antenna Installations
When installing a “balanced” antenna such as a Yagi or di-
pole, remember that the FT-897D is designed for use with
an (unbalanced) coaxial feedline. Always use a balun or other
balancing device so as to ensure proper antenna system per-
formance.
Use high-quality 50 Ωcoaxial cable for the lead-in to your
FT-897D 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 fre-
quency increases, so a coaxial line with 0.5 dB of loss at 7
MHz may have 6 dB of loss at 432 MHz (thereby consum-
ing 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 dif-
ferences 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 fig-
ures for typically- available coaxial cables frequently used
in HF installations.

Loss figures are approximate; consult cable manufacturer’s
catalogs for complete specifications.
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 an-
tennas’ support structure(s) adequately, so as to dissipate
energy absorbed during a lightning strike. Install appropri-
ate 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 com-
pletely from your station if the storm is not immediately
in your area. Do not allow disconnected cables to touch the
case of your FT-897D transceiver or accessories, as light-
ning can easily jump from the cable to the circuitry of your
transceiver 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 radiat-
ing 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.

INSTALLATION
RF FIELD EXPOSURE
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 per-
missible exposure to radio frequency 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 di-
rectly (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-897D transceiver itself, its antenna system
should be located as far away from humans and animals as
practicable, 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 opera-
tion) when RF power is applied, especially in the case of
430 MHz directional arrays. The 20 Watt power output sup-
plied by the FT-897D, 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 com-
puter or computer-driven accessories, you may need to ex-
periment with grounding and/or Radio Frequency Interfer-
ence (RFI) suppression devices (such as ferrite cores) to
minimize interference to your communications caused by
energy from the computer. Computer-generated RFI is usu-
ally a result of inadequate shielding of the computer’s cabi-
net or I/O and peripheral connections. While computer equip-
ment may “comply” with RF emission standards, this does
not ensure that sensitive Amateur Radio receivers like the
FT-897D will not experience interference from the device!
Be certain to use only shielded cables for TNC-to-Trans-
ceiver 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 inter-
connecting patch/data cables. As a last resort, you can try
installing additional shielding within the computer’s case,
using appropriate 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 tech-
niques.
HEAT AND VENTILATION
To ensure long life of the components, be certain to provide
adequate ventilation around the cabinet of the FT-897D.
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-gener-
ating 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.

LINEAR AMPLIFIER INTERFACING
The FT-897D provides the switching and drive-control lines
required for easy interfacing to most all commonly-avail-
able amplifiers sold today.
These include:
ÌThe Antenna Jacks (“HF/50MHz” and “144/430MHz”);
ÌA T/R control line (open circuit on RX, closure to ground
on TX); and
ÌA negative-going ALC jack (control voltage range: 0V
to –4V DC).
ÌWhen interfacing to the VL-1000 Solid State 1 KW Lin-
ear Amplifier, the optional CT-58 Interface Cable pro-
vides for easy interconnection (requires that the Menu
Mode No-020 [CAT/LIN/TUN]setting changes to “LIN-
EAR”).
The rear-panel CAT/LINEAR jack is an 8-pin, miniature
DIN type, with the “TX GND” pin providing a closure to
ground on transmit, for T/R control of your linear amplifier.
The ACC jack is a miniature stereo type, with external ALC
input capability on the tip connection. The main shaft is the
ground return. The ring connection of the ACC jack, when
closed to ground, places the FT-897D into the transmit mode,
and sends a steady CW carrier, for amplifier (or antenna
tuner) adjustment purposes.
Typical amplifier interface circuits are shown below.
Note that some amplifiers, particularly VHF or UHF “brick”
amplifiers, offer two methods of T/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-897D’s CAT/
LINEAR jack (“TX GND” pin). Alternatively, many of these
amplifiers use “RF Sensing” to control their relays; if yours
is in this category, you may then use the T/R control line
from the “TX GND” pin of the CAT/LINEAR jack for
control of your HF linear amplifier, and RF sensing for your
VHF or UHF amplifier.
The “TX GND” T/R control line is a transistor “open col-
lector” circuit, capable of handling positive amplifier relay
coil voltages of up to +50V DC and current of up to 400
mA. If you plan on using multiple linear amplifiers for dif-
ferent bands, you must provide external band-switching of
the “TX GND” relay control line from the CAT/LINEAR
jack.
Important Note!
Do not exceed the maximum voltage or current ratings
for the “TX GND” line at the CAT/LINEAR jack. This
line is not compatible with negative DC voltages, nor
AC voltages of any magnitude.
Most amplifier control relay systems require only low
DC voltage/current switching capability (typically, +12V
DC at 25 ~ 75 mA), and the switching transistor in the
FT-897D will easily accommodate such amplifiers.

CW KEY/KEYER CONNECTIONS
All commonly-available keyer paddles should work perfectly
with the built-in Electronic Keyer. The wiring configuration
for the paddle is shown below.
For straight-key operation, only the tip and shaft connec-
tions are used.
RECEIVER ACCESSORIES
(TAPE RECORDER ETC.)
Connection of a tape recorder or other such receiver acces-
sory is easily accomplished by using the DATA jack’s Data
Out (1200 bps) terminal (Pin 5) and Ground (Pin 2). The
audio output is fixed at 100 mV, with an impedance of 600
Ω.
INSTALLATION
Note: Even when using a straight key, you must use a three-
conductor (“stereo”) plug. If a two-conductor plug
is used, the key line will be constantly shorted to
ground.
When using an external electronic keyer, be absolutely cer-
tain that it is configured for “positive” keying, not “nega-
tive” or “grid block” keying. The “key-up” voltage of the
FT-897D is +5V, and the “key-down” current is only about
1 mA.
For CW automated keying using a personal computer, with
an external memory keyer providing for manual sending, it
usually is possible to connect the keyed lines together via a
“Y” connector. Check with the documentation accompany-
ing your keyer and your contest/DX software for any cau-
tions which need to be observed.
