FT-897: THE WORLD'S FIRST HF/VHF/UHF MULTIMODE PORTABLE/BASE STATION!

Now you can own a fully self-contained, high-power HF/VHF/UHF multimode transceiver that can be operated without an external power supply! With the exciting new FT-897, you can operate fully portable at the
20-Watt power level, using the optional FNB-78 13.2V/4500 mAh Ni-MH Battery Pack (two may be installed simultaneously). Use an external 13.8 Volt power supply for 100 Watts of power on HF/50 MHz, 50 Watts
on 144 MHz, and 20 Watts on 430 MHz. Or install the optional FP-30 Internal Power Supply in place of the internal batteries. . .however you configure the FT-897, there will be no limit to the DX action you'll enjoy!

FIELD STATION

FT-897+FNB-78

For an afternoon at the park, a day at the beach, or an emergency exercise, power your FT-897
using the optional FNB-78 Ni-MH Battery Pack, and you're on the air-completely portable!

The bottom side of the FT-897 contains a "power source tray" which can accommodate up to two
of the optional 13.2 Volt, 4500 mAh FNB-78 Ni-MH Battery Packs, for completely portable
operation without any external power source. Maximum power output is 20 Watts (70 cm: 10 W)
during battery operation, and with two FNB-78s you may expect up to eight hours of operating
time (TX 5%, RX 5%, standby 90%). What's more, you can charge one of the FNB-78 Battery
Packs while operating the FT-897 off the other pack—ideal for situations where solar or other
power sources are available. The CD-24 Charge Adapter provides the necessary voltage for
charging, and it may be used in conjunction with an external 13.8 Volt source, or the PA-26 AC
Adapter may be used to power the CD-24.

HF/VHF/UHF Communications Station

Measuring just 7.9" x 3.2" x 9.1" (without knobs),
the FT-897 is unmatched in performance versus
size. With the optional FC-30 Automatic Antenna
Tuner installed, the convenient carrying handle of
the FT-897 lets you easily transport your
HF/VHF/UHF station to a
portable location and get
on the air instantly.

Innovative FC-30

Automatic Antenna Tuner

Adding less than 2" to the total width of the
FT-897 assembly, the optional FC-30 is a
speed, relay-controlled Automatic Antenna
utilizing a combination of sixteen capacitors and
nine low-loss coils to reduce SWR as presented
to the FT-897 feedpoint. Impedances of 17 to 150
Ohms may be tuned by the FC-30 on HF (25 to
100 Ohms on 50 MHz), and the lightning-fast
tuning ensures that you won't miss out on the DX.

Easy Receiver Offset Tuning (Clarifier)

The convenient "Clarifier" (R.I.T.) knob, located at
the bottom right-hand corner of the front panel,
allows offset of the receiver frequency from the
transmitter frequency, to follow a drifting station or
to tune around a DX pile-up. But if you want a
larger knob for offset tuning, you may use the
Menu system to assign the Clarifier function either
to the Selector knob, or the Main Tuning Dial.

When you've traveled a great distance to find that
ultimate quiet operating location, you want a great
receiver so as to take advantage of it! Yaesu's top

FT-897+ATAS-120

Mobile operation, using the FT-897 as the cornerstone, is pure joy! The
combination of the FT-897 and the ATAS-120 Active-Tuning Antenna System
provides automated operation from HF through the UHF spectrum!

low noise low noise figure are the product of the
advanced preamplifier stage with negative
feedback for stability, and the
GaAs balanced mixer design,
with careful gain distribution from
the RF through the audio stages.
Flexibility in strong-signal operation
is also provided by the
control, input attenuator,
preamplifier bypass capability (IPO),
and Slow/Fast/Off AGC selections.

High-Performance PLL Design

The quiet, fast-acting local oscillator system of the
FT-897 borrows extensively from the renowned
FT-847, using a Direct Digital Synthesizer (DDS) to
achieve fast lock times and silky-smooth tuning in
10 Hz steps. The excellent carrier-to-noise ratio
helps preserve spurious-free dynamic range in a
crowded band, and the smooth tuning leaves you
with the feeling you’re using an analog VFO.

Digital and Analog Interference/Noise Reduction

The FT-897 includes a wide array of analog and
DSP filters to help you dig out those weak DX
signals on a crowded band! One-touch activation of
the DSP filters, plus a convenient "DSP" LED on
the front panel, enhance the ease of using the DSP.

DSP BANDPASS FILTER

Separate DSP Bandpass Filters for Voice and CW
augment the analog filters, yielding a dramatic
improvement in signal-to-noise ratio and interference
reduction. For Voice modes, both the low- and
high-side cutoff frequencies are independently
adjustable, and for CW you may choose bandwidths
of 240 Hz, 120 Hz, or a razor-sharp

DSP AUTO-NOTCH FILTER

To reduce interference caused
by annoying carriers within

carriers are present, the
DSP will detect and notch all
the carriers present.

DSP NOISE REDUCTION

The very effective DSP Noise
Reduction filter of the FT-897
is a tremendous operating aid,
greatly reducing background
noise without introducing
annoying distortion of the
desired signal. Operator
fatigue is reduced, while signal­to-noise ratio is significantly
enhanced.

IF NOISE BLANKER

Another noise reduction circuit, in addition to the
DSP Noise Reduction, is the IF Noise Blanker.
Noise pulses are detected early in the receiver,
then amplified and used to drive a carefully-timed
gate in the receiver IF that blanks out impulse­type noise from automotive ignition systems.

Upgrade with Collins® Mechanical

Filters for SSB and CW!

To enhance performance on both receive and
transmit, high-performance Collins
Filter options are available for both SSB and CW. For
SSB,

the 2.3 kHz, 10-pole model YF-122S (optional)
provides a very flat passband response, for natural­sounding transmit audio, along with excellent skirt
selectivity. And for CW, the 500 Hz, 7-pole YF-122C
(option)

helps separate signals on a crowded band

in a contest.

Outstanding Features for the CW

A wide array of features are tailored to the CW enthusiast
operating from home or on an expedition!

Included are a CW Tuning indicator, CW Pitch control,
Electronic Keyer with three memories and Weight
Control, and selection of Full QSK or "Semi-break­in" operation. For DX-pedition use, a unique "Beacon"
mode allows you to send a repetitive message on,

Limited-space Antenna Ideas

If you're living in an apartment, townhouse, or
other location where you don't have a lot of
space to install an antenna, ask your dealer for
a suitable balcony mount for the ATAS-120!
When using the ATAS-120 with the optional
ATBK-100 Antenna Base Kit (VHF/UHF

Active-Tuning Antenna System:

The ATAS Series! (optional)

Yaesu's patented ATAS-120 Active-Tuning Antenna System
provides a compact yet efficient, automatically-adjusting
antenna for mobile, portable, or apartment-balcony use!
Utilizing DC voltages fed from the FT-897 the ATAS-120
automatically adjusts its length longer or shorter, with the
FT-897 feeding a tiny amount of power for SWR detection by its
internal directional coupler. When the best impedance match is
found, tuning automatically stops, and operation can begin.

Specified for operation on the
7/14/21/28 MHz Amateur bands, the
ATAS-120 contracts fully for use on
the 50/144/430 MHz bands, providing
a low SWR for local FM work (where
vertical polarization is predominant).
And if you're an apartment dweller,
use the optional ATBK-100 Antenna
Base Kit, which provides an excellen
counterpoise to
ensure low-angle

VHF/UHF bands.
