hf/vhf/uhf
features
page 1 |
| measuring just 6.1 "x 2" x 9.2" (155 x 52
x 233 mm), the ft-857 is the world's smallest
full-power hf/vhf/uhf multimode transceiver!
|
|
| its
rugged case design is a masterpiece of ergonomic
design, with often- used switches and knobs
conveniently positioned for easy
access. |
|
borrowing extensively from the ft-897
transmitter design, the ft-857's rugged power
amplifier section utilizes bipolar transistor
devices, providing low noise, low distortion,
and high reliability. on hf and 6 meters, you
get 100 watts of clean power output, while on 2
meters you get 50 watts out, and 20 watts on 70
cm. reliability is assured
thanks to the extensive cooling system,
featuring a thermostatically-controlled fan and
aluminum diecast chassis.
|
|
ease of access to
features |
|
despite its compact size, the ft- 857 is
without peer in ease of access to the features
and functions you need the most!
?big-radio tuning dial and outstanding
ergonomics:
| ease
of operation of the ft-857 is enhanced by the
large diameter 1.7" (043 mm) main tuning dial
|
| (10hz
steps minimum), similar in size to the tuning
knob of many base station rigs. |
 |
| what's more,
the select knob allows "channelized"
tuning in
minimum steps of 1 khz on ssb/cw, or 5 khz on
fm, for quick and easy tuning around the band.
all important keys are strategically placed
around the front panel, for quick
access. |
?easy-to-use "scrolling front panel"
keys:
the compactness of the ft-857 is
made possible by the easy-to-use "multi
function" keys, which allow adjustment of a
number of transceiver operating functions during
operation. pressing the [func] key allows
selection of the operating function row, using
the selector knob, and you may then press the
[a], [b], or [c] key, as needed, to change the
setting. one row of keys may also be
custom-programmed by the operator, allowing you
quick access to a particularly
important set of
functions or menu items.
|
|
?ifshift:
use the if shift
feature to vary the centre frequency of the if
passband, so as to eliminate interference above
or belowthe current operating
frequency.
?if noise
blanker:
optimized for use in the mobile
environment, the ft-857 includes a
highly-effective if noise blanker specifically
designed for suppression of ignition and other
pulse-type noises. the noise bianker's threshold
is adjustable via the menu.
?intercept point optimization
(ipo):
for reception on the lower hf
bands, where low noise figure is not required,
the ipo feature causes the rf preamplifier to be
bypassed, allowing direct signal input to the
first mixer. an input attenuator is also
provided, forvery noisy
conditions.
?adjustable agc:
the
automatic gain control (ago circuitry of the
ft-857's receiver may be adjusted, by the
operator, for slow or fast recovery times. a
convenient "auto" feature programs "fast" agc
for cw, and "slow" for voice modes. and the agc
may also be turned off, if desired, allowing
manual gain control from the front
panel.
?clarifier
(r.i.t.):
for split-frequency pile-ups or
to follow drifting signals, the clarifier
control provides up to ±9.99 khz of adjustment
of the receiver's frequency, without changing
the transmit frequency. for wider-split pileups,
the "split" mode allows you to use vfo-a and
vfo-b separately.too.
?rf gain control:
for noise
reduction and/or variation of the agc system
threshold, the menu allows the front panel's
"squelch" control to operate as an "rf gain"
control.
?vox:
for hands-free
voice operation, the vox system includes easy
adjustments for both vox gain and delay. a
separate setting is also provided for receiver
recovery time in the cw mode, as
well. |
|
providing transmitter coverage of the hf,
50 mhz, 144 mhz, and 430 mhz amateur bands, the
ft-857 also includes receive coverage on 100 khz
to 56mhz, 76 to 108 mhz, 118-164 mhz, and
420-470mhz. enjoy the excitement of public
safety monitoring, along with weather
broadcasts, am and fm broadcasts, aviation

feature is also provided, along with the ability
to encode (only) ctcss or dcs, if
desired.
automatic repeater shift:
on the 144 mhz and 430 mhz bands, the ft-857
will automatically activate the repeater shift
appropriate for the part of the band in which
you are operating.
?smart search?:
when visiting a new city, use the smart
search system to scan the fm/am mode for
activity. when busy channels are found, they
will be automatically loaded into a special
smart search? memory bank, for easy
recall.
?spectrum scope:
if you
have to be away from your radio for a few
minutes, turn on the spectrum scope to keep
watch on band activity. the spectrum scope will
create a bar-graph display of activity on
channels above and below frequency.
?arts?
(auto-range transponder system)
:
during search-and-rescue operations, the
artstm feature will notify you if a field
station (for example, a low-power hand-held
unit) has gone out of communications range, so
you can instruct them to move to a better
location. |

active tuning atas-120
(option) |
| 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-857, the atas-120 automatically adjusts its
length longer or shorter, with the ft-857
feeding a tiny amount of power for swr detection
by its internal directional coupler.
when the
best mpedance
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
outstanding counterpoise to ensure low-angle
radiation on the vhf/uhf bands.
see your yaesu dealer for details
regarding suitable mounts for the
atas-120. | | |
|
|
to enhance
performance on both receive and transmit,
high-performance collins? mechanical filter
options are available for both ssb and
cw.
for ssb, the 2.3 khz, 10-poleyf-122s
option provides a very flat passband response,
for natural-sounding transmit audio, along with
excellent skirt selectivity. and for cw, the 500
hz, 7 pole yf-122c and 300 hz, 7-pole
yf-
122cn options help separate signals on a crowded
band in a contest.
 |
the ft-857
provides up to 200 "main" memory channels, each
of which may be named with an alpha-numeric
label of up to eight characters.
these 200
memories may be separated into as many as 10

high performance
receiver |
| building on the acclaimed performance of
the ft-1000d, mark-v ft-1000mp, and ft-897,
yaesu's engineers have crafted the ft-857's
front end for a very low noise floor, along with
wide dynamic range. utilizing an up-conversion
architecture for with a first if of 68.33 mhz,
the ft-857 features a double-conversion
superheterodyne system (single conversion on
wfm), with the 2nd if at 455 khz.
extensive bandpass filtering in the front
end, along with careful device selection and
gain distribution, yield a receiver system ready
for the strong signal challenges of today's
crowded bands! on vhf and uhf the very-low-noise
mos fet preamplifier is followed by an active
dbm |
| mixer, yielding the lown oise figure
required for weak-signal work, along with
excellent intermodulation rejection. |
 | |
|
high performance pll
design |
| the
quiet, fast-acting local oscillator system of
the ft-857 borrows extensively from the ft-847
and ft-897, using a direct digital synthesizer
(dds) to achieve fast lock times and
silky-smooth tuning in steps as fine as 10 hz.
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. |
|
enhanced performance
(dsp) |
| for
superior interference rejection and transmitter
"talk power/the ft-857's dsp circuitry enhances
both sides of the communications
circuit. |
| the
ft-857's dsp unit features a 24-bit high-tech
d/a chip for signal processing. |
 |
?dsp bandpass filter:
separate dsp bandpass filtersforvoice and
cw augment the analog filters for enhanced
interference rejection. for voice modes,you get
16 high-pass filter cutoff frequency selections,
and 32 low-pass filter selections, for a total
of 512 combinations. and for cw, you may choose
bandwidths of 240 hz, 120 hz, or arazor-sharp 60
hz.
?dsp auto-notch
filter :
to reduce interference caused by
annoying carriers within the audio passband,the
dsp auto-notch provides a significant reduction
in the interference level. if multiple carriers
are present, the dsp will detect and notch all
the carriers present.
?dsp noise
reduction:
the very effective noise
reduction filter of the ft-857 utilizes as many
as 16 noise-reduction algorithms, for use in a
wide variety of noise environments, without
introducing appreciable distortion on the
desired signal. operator fatigue is reduced, and
signal-to-noise ratio is significantly
enhanced.
?dsp
microphone equalizer:
to match the
ft-857's tx audio response to the waveform
produced by yourvoice andthe microphone in use,
the dsp system includes a four-position mic
equalizer circuit. the result is increased "talk
power" as extraneous frequencies are suppressed,
allowing all available powerto be concentrated
into your voice's
pattern. |
the
ft-857 is without peer in its array of
most-asked- for features for the cw
expert!
?built-in electronic keyer
:
the ft-857's built-in electronic keyer
includes a weight control, as well as menu
capability to reverse the "dot" and "dash"
contacts on your connector.
?cw message
memory with beacon mode :
for repetitive
"cq test" and contest exchange messages, the
ft-857 includes a three-message memory
capability. the "beacon" mode may be used to
send a repetitive message out continuously for
up to four hours, ideal for 6-meter use during
dx peditions.
?cw pitch/sidetone control
:
the cw pitch control allows the
transmitted signal to be offset
400/500/600/700/800 hz from "zero beat" with the
receive frequency. this adjustment
simultaneously varies the centerfrequencyofthe
rx passband (including the dsp bpf), as well as
the cw sidetone pitch. the sidetone therefore
serves as a "spot" signal during
tuning.
?cw trainer:
a popular
feature of the ft-857 is the cw trainer, which
will send five character letters and/or numbers
via the speaker, so you can practice your cw
reception even when the bands are
dead! |
| for
operation on a wide variety of digital modes,
including 1200/9600 bps fm packet, rtty, sstv,
or psk31,the rear-panel 6-pin mini-din connector
provides easy to data i/o lines, plus ptt and
ground. for psk-31 and other afsk modes, the
injection sideband (usb/lsb) is
selectable,:along with bfo and display shift and
