HF+VHF+UHF ALL MODE TRANSCEIVER
The FT-847 Earth Station: A masterpiece of
high-tech design and packaging know-how!
Utilizing the latest computer-aided design techniques and
thousand of "chip" components. Yaesu's engineers have achieved
an engineering breakthrough that was only a dream just a few
years ago: a full-power transceiver covering HF, 50 MHz, 144
MHz, and 430 MHz bands in a package about 2/3 the size of an
average briefcase. Ready for action on SSB, CW, AM, FM, and
digital modes, the FT-847's ultra-compact size makes it ideal
for serious base stations use, and well as a variety of portable
and mobile applications, including Field Day, DX-peditions,
VHF/UHF "Rove" operation, and RV installations. And long-term
reliability is ensured by the rugged construction, featuring an
aluminum diecast chassis which doubles as the power amplifiers’
heat sink.
Unmatched for Satellite
Operation
The FT-847 includes crossband full duplex operatin,
so you can hear yourdownlink signal while
transmitting (on a different band) on the uplink.
The FT-847 is ready for operatin 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), or Mode T (TX: 21
MHz, RX: 145 MHz). Independent display of both the
TX and RX frequencies is provided, and twelve
dedicated Satellite VFOs allow you to set the
transceiver up for operation on a number of
different transponders. Both "Normal" and "Inverted"
tracking of the uplink and dosnlink VFOs is
available.
Leading-Edge Receiver Design
Strong enough to survive the rigors of competitive
HF operatin, yet sensitive enough for stand-alone
Moonbounce operation without an external
preamplifier, the receiver section of the FT-847
includes a low noise preamplifier, followed by a
quad-FET first mixer, whch provides outstanding
rejection of intermodulation. On 430 MHz, the
receiver preamplifier is a HEMT device, for
extremely low noise. And if you have tower-mounted
preamplifiers you wish to utilize, the FT-847 can be
configured to bypass the internal preamp in favort
of passing +12V through your coax line to power your
preamplifier. MENU
FEATURE 29 AND 30 SHOULD BE READ ABOUT IN YOUR OWNER
MANUAL. OWNERS MANUAL IS ALSO AVAILABLE IN PDF.
Built-in Digital Signal Processing (DSP)
For improved interference rejection, or enhancement
of the signal-to-nise ratio, the FT-847 incvludes a
sophisticated audio DSP system. Featuring
Auto-Notch, Noise Reduction, and Bandpass Filter
circuits, the DSP is an effective tool for improving
receiver performance. The Bandpass Filter is
particularly effective in weak signal work, such as
EME (Moonbounce), as the CW bandwidth may be reduced
to a razor-sharp 25 Hz, with a variable center
frequency. This can yield almost 10 dB of
signal-to-noise improvement over many commonly-used
audio filters. WHEN
WE ADDED A
DCI FILTER THE 2MM AND 440 RECEIVE RANGE BECAME
SIGNIFICANT. REPEATERS WE INSTANTLY HEARD AT 60 TO
80 MILE. NO FILTER THE INTERMOD WAS LIMITING US TO
25 MILES ON MOST SIGNALS. ON 2MM SSB CONTACTS JUMPED
FROM 30 TO 450 TO 500 MILES EAST ACROSS IOWA AND
INTO ILLINOIS.
Shuttle-Jog™ Quick Tuning Aid
THIS WORKS GREAT
First introduced on Yaesu's FT-1000MP transceiver,
the Shuttle-Jog™ Tuning Ring provides rapid
frequency change by its unique spring-loaded design.
Rotating the Shuttle-Jog™ ring slightly to the left
or right beginas manual scanning to lower or higher
frequencies, respectively; lean the ring further,
and the scanning rate increases!
High-Contrast Multi-Function Blue Liquid
Crystal Display (LCD)
The large blue LCD provides high resolution and
contrast for easy viewing from a wide range of
angles and light levels. Dozens of status indicators
keep you informed of every aspect of your FT-847's
operating characteristics, with a large Sub-VFO
field on the right side being particularly helpful
during satellite operation. The LCD's illumination
brightness is adjustable via an 8-level dimmer
function.THIS
RADIO FEATURES GREAT DATA ABILITIES ALSO.
