Installation
Power Connections
The FT-897 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 External AC Power Supply).
External DC power source operation
The DC power connector for the FT-897 must only be connected to a DC source providing
13.8 Volts DC (±15%), 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.
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 voltage stability.
Tips for Successful Mobile Installations:
B efore 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.
Route the DC cable as far away from the ig nition cables as possible.
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).
Check the battery terminal connections frequently to be sure t hey are tight and
not corroded.
Caution
Permanent damage can result if improper supply v oltage, or reverse-polarity v oltage, is
applied to the FT-897. 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 ±15%. Never attempt to con nect the FT-897 to a 24 Volt battery

system.
When replacing fuses, be certain to u se a fuse of the proper rating. The FT-897 require s a
25A fast-blow fuse.
AC power source operation (require s opt i onal FP-30 AC power supply)
For base station installati ons, Yaesu recommends the use of the FP-30 AC power supply.
Installation
1. Remove the six screws (three screws on bottom side and rear side), then lift off the
bottom cover.
2. Attach the FP-30 to the bottom of the FT-897, then affix it in place with the six
screws removed above st eps.
3. Connect the 6-pin Molex plug from the FP-30 to the INPUT jack on the rear panel of
the FT-897.
4. Make sure that your AC voltage is correct and turn the FP-30 POWER switch to off,
connect the AC power cable between the INPUT jack on the rear panel of the FP-30
and A C wal l outl et.
Operation
1. To turn the transceiver on, turn on the POWER switch on the FP-30 before turning
on the PWR switch on the FT-897.
2. To turn the transceiver off, turn off the PWR switch on the FT-897 before turning off
the POWER switch on t he FP-30.
Internal battery operation (requires optional FNB-78 Ni-MH battery pack)
The optional FNB-78 Ni-MH Battery Pack provides 13.2 Volts of DC power for your FT-
897, with a maximum capacity of 4800 mAh (you may install the two FNB-78 into the
FT-897, in this time, maximum capacity is 9.6 Ah!).
Installation
1. Remove the six screws (three screws on bottom side and rear side), then lift off the
bottom cover.
2. Insert the FNB-78 into the battery compartment “A” or “B” on the bottom of the
radio so that the battery’s mounting tab is aligned with the mounting hole on the
radio’s chassis.

chassis, which is same label (“A” or “B”) of the battery compartment witch is the
FNB-78 installed.
4. Remove the plastic cap, which is same label (“A” or “B”) of the battery compartment
witch is the FNB-78 installed, from the to bottom cover, before turning the plastic
cap so that the small project of the cap is aligned with the slot of the bottom cover.
5. Replace the bottom cover and its six screws.
Charging
Charging of the FNB-78 requires the use of the optional PA-26 Battery Charger and
CD-22 Charge Ada pte r.
1. Turn the radio off.
2. Connect the cable plug from the PA-26 battery charger into the INPUT jack on the
CD-22 Charge Adapter, then insert the cable plug from the CD-22 into the “CHG-A”

3. Connect the AC cable into the AC jack on the PA-26, th en plug the PA-26 in to the
AC wall outlet.
4. The “BATT-A” or “BATT-B” indicator on the front panel of the FT-897 will glow red
(Charging) while the battery is being charged. When charging is completed, the red
LED indicator will change to green (Fully Charged). A fully-discharged pack will be
charged completely in about <<??>> hours.
5. Unplug the cable from the CHG terminal, then disconnect the PA-26 from the AC
wall outlet.
Operation
Before turn the radio on, select the battery to be used by top panel’s A-B switch.
Grounding
The provision of an effective ground system is important in any successful
communications station. A good ground system can contribute to station efficiency in a
number of ways:
It can minimize the possibility of electrical shock to the operator.
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
entertainment devices or laboratory te st equipment.
It can minimize the possibility of erratic transceiver operation caused by RF
feedback or improper current flow through logic devices.

Vertex St andard Co., Ltd.
FCC ID: K66FT-897
Operating Manual
An effective earth ground system may tak e several forms; for a more complete d iscussion,
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 instal lations will be achieved vi a 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 optional MMB-?? Mobile Bracket will
accomplish this, if the MMB-?? 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 grounding. These
symptoms may include:
RF feedback (resulting in distortion on your transmitted signal);
Unintended frequency change;
Blinking or blanking of the frequency d is play;
Noise pickup; and/or
Loss of memory.
Note that these conditions may occur in any communications installation. The FT-897
includes extensive filtering designed to m in imize th e chance of such problems; however,
random currents set up by insufficient RF g r ounding can nullify such filtering. Bond ing
the rear panel Ground lug of the FT-897 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 ante nnas unles s the shiel d of the
coaxial cable is securely grounded near the feedpoint of the antenna. Such antennas
frequently are responsible for the ground-related difficulties described above.
Base Station Earth G r ounding
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

Operating Manual
location. 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 weatherproof the connections 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 gro und 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 supplies, and data communications devices shoul d be made directly to the groun d
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 Ground lug on the FT-897
rear panel.
Antenna Considerations
The antenna systems connected to your FT-897 transceiver are, of course, critically
important in ensuring successful communications. The FT-897 is designed fo r use with
any antenna system providing a 50Ω resistive impedance at the desired operating
frequency. While minor excursions from the 50Ω specificatio n are of no consequ ence, 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 33 Ω or greater
than 75 Ω, corresponding to a Standing Wave Ratio (SWR) of 1.5:1).
Two antenna jacks are provided on the rear panel of the FT-897. 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.

Operating Manual
Guidelines for successful base and mobile station installations are shown below.
Mobile Antenna Installations
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-30 Automatic Antenna Tuner, which will present a 50Ω imped ance to yo ur
transceiver on the 1.8 ~ 50 MHz bands so long as the SW R 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 50Ω be performed at the
antenna feedpoint.
Yaesu’s Active-Tuned Antenna System (ATAS-120) is a unique HF/VHF/UHF mobile
antenna system, which prov ides a utom at ic tuni ng w hen us ed wit h t he FT-897. S ee p age
<<??>> for full details on the ATAS-120.
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 considerations; vertical antennas are almost always utilized on HF for this
reason.
Base Station Antenna Installations
When installing a “balanced” antenna such as a Yagi or dipole, remember that the FT-
897 is designed for use with an (unbalanced) coaxial feedline. Always use a balun or
other balancing device so as to ensure pro per a nten na s y stem performance.
Use high-quality 50Ω coaxial cable for the lead-in to your FT-897 transceiver. All efforts
at providing an efficient antenna system will be wasted if poor quality, lossy coaxial
cable is used. Losses in coaxial line s increase as the freque ncy increases, so a coaxial line
with 0.5 dB of loss at 7 MHz may have 6 dB of loss at 432 MHz (thereby consuming 75%
of your transceiver’s power output!). As a general rule, smaller-diameter coaxial cables
10
Vertex St andard Co., Ltd.
FCC ID: K66FT-897
Operating Manual
tend to have higher losses than larger-diameter cables, although the precise differences
depend on the cable construction, materi als, a nd the qual ity of the connect ors u sed with
the cable. See the cable manufacturers’ s pecifications for details.
For reference, the chart below shows approximate loss figures for typically- available
coaxial cables frequently used in HF instal lations.
Always locate antennas such that they can never come in contact with outdoor power
lines in the event of a catastro phic support or powe r-pole structural failure. G round your
antennas’ 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 cable s com plete ly from yo ur stat ion if the st orm is not imme diately in
your area. Do not allow disconnected cables to touch the case of your FT-897 trans c eiv er
or accessories, as lightning can easily jump from the cable to the circuitry of your
transceiver via the case, causing irre par able 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 shou l d strike your antenna structure or a nearby p ow er 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 st orm). The burie d
radials of a ground-mounted vertical antenna can carry let hal voltages outward from the
center of the antenna in the event of a direct lig htning strike.
RF Field Exposur e
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 frequency energy. Compliance is based on the actual power output
used, feedline loss, antenna 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

Operating Manual
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 0611 1 or <http://www.arrl.org>).
Although there is negligible radio frequency (RF) leakage from the FT-897 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 operation) when RF power is
applied, especially in the case of 430 MHz directional arrays. The 20 Watt power output
supplied by the FT-897, 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
accessories, you may need to experiment with grounding and/or Radio Frequency
Interference (RFI) suppression devices (suc h as ferrite cores) to minimize interfere nce to
your communications caused by energy from the computer. Computer-generated RFI is
usually a result of inadequate shielding of the computer’s cabinet or I/O and peripheral
connections. While computer equipme nt may “comply” with RF emissio n standards, thi s
does not ensure that sensitive Amateur Radio receivers like the FT-897 will not
experience interference from the device!
Be certain to use only shielded cab les for TNC-to-T r ansceiver co nnections. You may need
to install AC line filters on t he power cord(s) of the suspected eq uipment, and deco upling
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
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 techniques.

Heat and Ventilation
To ensure long life of the components, be certain to p rovide adequate ventilatio n around
the cabinet of the FT-897. The cooli ng system of the transc eiver 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-generat ing device (such as a linear
amplifier), and do not place equipment, books, or papers o n top of the transceiver. Place
the transceiver on a hard, flat, stable s urface. Avoid heating vents a nd win dow lo cati ons
that could expose the transceiver to excessive direct sunlight, espec ial ly i n hot climates.
Linear Amplifier Interfacing
The FT-897 provides the switching and drive-control lines required for easy interfacing
to most all commonly-available amplifiers sold today.
These include:
The Antenna Jacks (“HF/50MHz” and “144/430MHz”);
A T/R control line (open ci rcuit on RX, closure to grou nd on TX); and
A negative-going ALC jack (control voltage range: 0V to –4V DC).
When interfacing to the VL-1000 Solid State 1 KW Linear Amplifier, the
optional CT-58 Interface Cable provides for easy interconnectio n (requires that
the Menu Mode No-80 [SIO MODE] setting changes to “LINEAR”).
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 a re shown below.
Note that some amplifiers, particularly VHF or UHF “brick” amplifiers, offer two
methods of T/R switching: app lication 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-897. Alternatively, many of these amplifiers use “RF Sensing” to
control their relays; if your s is not in t his category, you may t hen use t he T/ R contr ol li ne
from the ring of the ACC jack for control of your HF linear amplifier, if desired.
13
Vertex St andard Co., Ltd.
FCC ID: K66FT-897
Operating Manual
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 mA. If you plan on
using multiple linear amplifiers for different bands, you must provide external bandswitching of the “Lin Tx” relay control line from the “ring” connection of the ACC jack.
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 switching
capability (typically, +12V DC at 25 ~ 75 mA), and th e switching tran sistor in the FT-897
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 config uration for the paddle is shown below.
For straight-key operation, only the ti p a nd shaft connections are used.
Note: Even when using a straight key, you must use a three-conductor (“stereo”) plug. If
a two-conductor plug is us ed, the key line will be const ant ly shorted to ground.
When using an external electronic keyer, be absolutely certain that it is configured for
“positive” keying, not “negative” or “grid block” keying. The “key-up” voltage of the FT-
897 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 accompanying your keyer and your
contest/DX software for any cautions which need to be observed.
Receiver Accessories (Tape Recorder etc.)
Connection of a tape recorder or other such receiver accessory 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 m V, with an impedance of 600 Ω.

This transceiver covers an incredibly wide frequency range, over which a number of
different operating modes are use d. Therefo re, this tr ansce iver’s fr equ ency cov erage ha s
been divided into different operating bands, each of with has its own pre-set channel

R.F. Says: You can also set VFOa and VFOb to different modes in the same band,
allowing you to have a “ Ph o ne” VFO and a “CW” VFO, f or ex ample.
Adjusting the Audio Volume Level
Rotate the AF knob to set a comfortable listening level.
When operating in the “DIG” or “PKT” modes, you may set the AF knob to any
comfortable setting, or even all the way off, because the output from the DATA jack is a
fixed-level audio signal.
R. F. Says: Start with the AF knob set fully counter-clockwise, especially when using
FM (the background noise on FM can be sur pri si ngly loud)!
Menu Quick Start
Many aspects of this tran sceiver’s conf iguration may be customized us ing the convenie nt
“Menu” system, which allow you to configure many “set and forget” settings just the way
you want to. A full discussion of the Menu system beings o n page <<??>> ; for now, here is
a brief discussion on how to change Menu settings:
1. Press and hold in the [F] key for one second to enter the Menu mode.
2. Rotate the MEM/VFO CH knob to recall the Menu Item to be changed (for example,
Menu Mode No-001 [EXTEND], which Enables or Disables the extended Menu
Modes).
3. Rotate the DIAL knob to set this feature (in this example, the default setting is “OFF
(Disables),” so rotate the DIAL knob to set this feature to “ON (Enables).”
4. Pr ess and hold in th e [F] key for one second to save the new setting and exit to
normal operation.
R. F. Says: If you have momentarily pressed the [F] key to enable the changing of the

Adjusting the RF Gain and Squelch
The SQL/RF Gain control is configured differently, depending on the country to which
the FT-897 has been exported. In the U.S. version, the default function of this control is
“RF Gain.” The configuration of the SQL/RF Gain control is set via Menu Mode No-081
[SQL RF GAIN]; see page <<??>> for details.
If your transceiver is configured for “RF Gain” use, rotating this control fully clockwise
in the SSB/CW/Digital modes will provide best sensitivity. To reduce the receiver’s RF
Gain somewhat, rotate this control counter-clockwise slightly. You will observe an
increasing number of bars on the S-meter as you rotate the RF Gain control counterclockwise; th is in di cat es inc reas ing AGC voltage, which is causin g t he front-e n d gain to
be reduced. In the FM and Packet modes, this control will automatically be set to
“Squelch,” even though the setting of Menu #45 is set to “RF Gain.”
If this control is configured for “SQL” operation, the FT-897’s RF Gain will be set for
maximum sensit ivit y in all mo des, and the SQL/RF Gain control wi ll functio n sole ly as a
Squelch control. In this case, rotate the SQL/RF Gain control to the point where the
background noise is just silenced; this will provide the best sensitivity to weak signals,
while keeping the receiver quiet when no signal is received. The LED just above the
Main Dial will glow Green when the squelch is open ed by an incoming signal or nois e.
R. F. Says: Battery consumption is significantly reduced if the receiver is squelched, as
the audio amplifier stage is shut off when the receiver is muted.
Setting the Operating Frequency
1. In the “SSB/CW/DIG” modes, rotate the DIAL knob to set the frequency. Clockwise
rotation of the DIAL increases the op erating frequency.
2. In the “AM/FM/PKT” modes, rotate the MEM/VFO CH knob to set the frequency.
Clockwise rotation of the ME M/VFO CH i ncreases the operating frequency.
3. You may also use the MEM/VFO CH knob to adjust the operating frequency in the
“SSB/CW/DIG” modes. The MEM/VFO CH knob provides faster tuning, ideal for
making quick changes in frequency when you want to move across the band in a
hurry. You can then use the DIAL to make fine fr equency adjustments.
4. If you press the MEM/VFO CH knob momentarily, then rotate the MEM/VFO CH
knob, you can now change the operating frequency in 1 MHz steps, allowing very
29

quick frequency excursions. This can be particularly helpful on the VHF and UHF
bands.
5. In step 2 above, it was mentioned that tuning in the “AM/FM /PKT” modes is
accomplished using the MEM/VFO CH knob. By default, the DIAL is disabled in
these modes; if you wish to enable the DIAL in these modes, use Menu Mode No-004
[AM/FM DIAL]; see page <<??>>.
6. The synthesizer steps for the MEM/ VFO CH knob may be adjusted independently by
mode. Use Menu Mode No-006 [AM STEP] for AM, No-053 [FM STEP] for FM, and
No-083 [SSB STEP] for SSB/CW/Digital. See pages <<??>> for details.
R. F. Says: The main DIAL synthesizer’s tuning rate (th e number of st eps per rotat ion of
the DIAL) can be adjusted using Menu Mode No-036 [DIAL STEP]. See page <<??>> for
details.
Stacked VFO System
1. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until
Multi Function Row “ a” [A/B, A=B, SPL] appears on the display.
2. Now press the [A](A/B) key to toggle between the “A” and “B” VFOs. There are two
such VFOs provided on each Amateur band, so you may set VFO-A to the CW subband, and VFO-B to the SSB sub-band, if you like. The operating mode will be
preserved, along with the frequency information, on each VFO.
Receiver Accessories
Locking Front Panel Controls
The front panel LOCK button allows you to disable the DIAL and/or the front panel
controls.
In the transceiver’s default configuration, pressing the LOCK button disables just the
DIAL, while the other keys and switches are unaffected.
To lock out the remainder of the controls and the MEM/VFO CH knob, use Menu Mode
No-055 [LOCK MODE];
1. Press and hold in the [F] key for one second to enter the Menu mode.
2. Rotate the MEM/VFO CH knob so as to recall No-055 [LOCK MODE].
3. Rotate the DIAL to select the desired .
