FT-847
Enjoy the full spectrum of Amateur Radio excitement
with the FT-847 Earth Station!
Ready for action on SSB, CW, HSCW, AM, FM, Packet, SSTV, and RTTY, the FT-847 expands your operating
horizon beyond HF to the 6-meter, 2-meter, and 70-centimeter bands, featuring DSP and full-duplex satellite
operation, all within a super-compact package!
The FT-847 Earth Station: A masterpiece of high-tech design
and operating know-how!
Leading-Edge
ReceiverDesign!
Providing performance optimized on
each operating band, the FT-847’s high-performance
receiver section carefully blends excellent sensitivity,
low noise, and outstanding strong-signal-handling
capability. The front end s low-noise-figure
preamplifier (HEMT device on 70 cm!) is followed
by a quad-FET first mixer, providing outstanding
rejection of Intermodulation.
The net result of the FT-847’s advanced design
is a receiver with wide frequency coverage, yet easily
capable of hearing

Mechanical Filters!
The Yaesu engineering team has crafted an outstanding
DSP system for the FT-847, providing significant
enhancements to receiver performance. The DSP
Bandpass filter provides independently-adjustable
Low- and High-Cut filter elements, ideal for reducing
QRM on SSB, while the CW Bandpass Filter provides
fixed selectivity selections of 400 Hz, 200 Hz, 100 Hz,
and even 25 Hz, ideal for EME and other weak-signal
work. The DSP Noise Reduction circuit provides 16
different noise-reduction algorithms, for enhancement
of signal-to-noise ratio. And the Automatic Notch Filter
will seek out and null unwanted carrier signals, with
minimal distortion

waveforms.
Renowned for their excellent frequency
response and fidelity, Collins®
Mechanical Filters in 2.5 kHz and
500 Hz (-6 dB) bandwidths are available
for the FT-847 (separate TX and RX
SSB filter slots available). The Collins®
SSB filter provides a very "flat"
passband response which faithfully
reproduces both voice and data signals.
The Collins® CW filter is ideal for CW
or RTTY work, with Wide/Narrow
selection available from the front panel.

The FT-847 Earth Station: The All-in-One Solution to Your Operating Needs!
The FT-847’s compact size and wide frequency coverage make it ideal for serious base station use, as well as a variety of
portable and mobile applications, including Field Day, DX-peditions, VHF/UHF “Rover” operations, and RV installations.
Unmatched Satellite Operation Capability!
High-Reliability Transmitter Design!
The FT-847 provides 12 "Satellite" VFOs, automatically
configured for crossband full duplex (simultaneous
TX and RX) operation, with "Normal" and "Inverted"
VFO tracking so you can tune across a satellite
transponder downlink without having to make
manual uplink frequency adjustments.
The FT-847 is ready for operation on Mode A
(TX:145 MHz, RX:29 MHz), Mode B
(TX:435 MHz,RX:145 MHz), Mode J
(TX:145 MHz, RX: 435 MHz), and
Mode T: (TX:21 MHz, RX:145 MHz).
Independent display of both uplink
and
downlink
frequencies is provided,
and each satellite VFO
may be labeled with an
Alpha-numeric name,
Utilizing carefully specified and selected bipolar
power transistors, the FT-847’s rugged transmitter
takes advantage of the low noise characteristics of
the DDS (Direct Digital Synthesizer) local oscillator
circuitry to produce a reliable, clean transmitted
signal. Power output is 100 Watts on HF and 6 meters,
and 50 Watts on 2 meters and 70 cm. Twin cooling
fans ensure efficient dissipation of heat, ensuring
reliable operation on digital modes or during contests.

AUTO-TUNE ANTENNA:
The patented ATAS-120 (Active-Tuning Antenna System)
provides automatic resonating
adjustments when used with the
FT-847, utilizing a control voltage
fed to the ATAS-120 from the
antenna jack of the FT-847. No
other "antenna tuner" or control
cable is required! The ATAS-120 may
be used on the 7/14/21/28/50/144/430
MHz bands, and it is compatible
with many common mobile mounts,
which are available from your
Motor Drive Auto-Tuning
Yaesu dealer. Coaxial cable is Antenna System
ATAS-120
not included.
Superb Ergonomics for Efficient Operation
•SHUTTLE-JOG™ TUNING ENHANCEMENT
The SHUTTLE-JOG™ tuning ring provides rapid
frequency change for quick sweeping of a band.
Just lean the rig slightly to the left or right to begin
manual scanning to lower or high frequencies,
respectively. The separate Sub-VFO tuning knob
may be used as a Clarifier ( R.I.T. ) control, or
for initial setup of the uplink/ downlink relationship
during satellite operation.
Innovative Receiver Features Enhance
Your Operating Experience!
• EXPANDED RECEIVE FREQUENCY RANGE:
37-76, 108-174, and 420-512 MHz. So you can check
propagation below 6 meters, monitor the 4-meter
band, download images from weather satellites, or
follow the action on public safety frequencies!
• IF SHIFT:
For adjustment of IF passband to avoid interference.
• IF NOISE BLANKER:
For reduction of automotive ignition noise.
• INPUT RF ATTENUATOR:
For more comfortable reception of extremely strong
signals.
• FIXED-LEVEL AF OUT JACK:
For connection to tape recorder, WeatherFax decoder,
sound card, etc.
•COMPATIBILITY WITH ATAS-120
• HIGH-CONTRAST MULTI-FUNCTION DISPLAY
Leading-Edge Features for
Today’s Active Amateur!
The large (7.9" x .79") blue LCD provides high
resolution and contrast for easy viewing over a wide
range of angles and light levels. Dozens of status
indicators keep you informed of every aspect of
your FT-847’s operational characteristics.
•CW OPERATING FLEXIBILITY:
Besides the ultra-narrow DSP filtering for weak signal
work, the FT-847 includes a built-in iambic keyer
with weight control, and either USB or LSB-side
injection may be used for CW reception, thanks to
the "CW Reverse" feature. And the ultrafine tuning
steps as small as 0.1 Hz provide a tuning "feel" as
smooth as that of an analog VFO!
•SSB EXCELLENCE:
The FT-847’s "talk power" is enhanced by the built-in
RF clipping type Speech Processor, which increases
average SSB output by approximately 6 dB. And the
transmitted IF passband frequency may be adjusted,
via Menu, to match or enhance the frequency
characteristics of your voice pattern.
•EASY DATA-MODE OPERATION:
Convenient interface jacks are provided for interfacing
to TNCs, sound cards, or other modem devices.
For SSB-based data modes, the three-pin DATA
IN/OUT jack supports AFSK input and output, plus
PTT control. And for 1200/9600 bps packet work,
the PKT jack provides optimized input and output
lines, plus PTT and squelch status lines.
•OUTSTANDING FM FEATURES AND
FLEXIBILITY:
Included are independently programmable repeater
shifts for 29, 50, 144, and 430 MHz, Automatic
Repeater Shift (ARS) on 144/430 MHz, FM Wide/
Narrow modes for 29 MHz or crowded VHF/UHF
environments, built-in CTCSS/DCS Encoder/Decoder
circuits, and a Discriminator Center Meter, for precise
tuning on Doppler shifted FM satellite signals.
• OPTIONAL VOICE FREQUENCY
ANNOUNCEMENT MODULE (FVS-1A)
For operators with impaired vision, the FT-847 includes
provision for the optional FVS-1A Voice Synthesizer,
which gives you an audible announcement of the
current operating frequency (with resolution to the
nearest 100 Hz step).
Popular Memory and Scanning Features
The FT-847 provides 78 regular memories, plus
upper/lower band scanning limit memories, a CALL
channel, and a HOME channel on each band. A twochannel Quick Memory Bank (QMB) allows instant
recall of urgently-needed frequencies, and twelve
special Satellite VFO memories with 8-character
Alpha-Numeric labels allow you to note the satellite
name or transponder mode (e.g. AO10B ).
Versatile scanning capabilities of the FT-847 include
band scanning, memory channel scanning, Priority
Channel scanning, and SMART SEARCH™, whereby
the transceiver will sweep the band, automatically
loading a special memory bank with up to 20
frequencies where activity is encountered.
