Installation
Power Connections
The FT-857 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 Internal AC Power Supply).
External DC power source operation
The DC power connector for the FT-857 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:
ρBefore 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.
ρRoute the DC cable as far away from the ignition cables as possible.
ρIf 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).
ρ Check the battery terminal connections frequently to be sure they are tight and not corroded.
ρ When operating with the vehicle turned off, or operating from a stand-alone car battery (in a camp site, etc.), be
mindful of the minimum operating voltage (11.73 Volts) for the FT-857. If the battery is not charged sufficiently to
maintain at least 11¾ Volts at the radio, erratic operation or shut-down may occur.
Caution
Permanent damage can result if improper supply voltage, or reverse-polarity voltage, is applied to the FT-857. 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 connect the FT-857 to a 24-Volt battery
system.
When replacing fuses, be certain to use a fuse of the proper rating. The FT-857 requires a 25A fast-blow fuse.

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:
ρIt can minimize the possibility of electrical shock to the operator.
ρIt 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 test equipment.
ρIt can minimize the possibility of erratic transceiver operation caused by RF feedback or improper current flow
through logic devices.
An effective earth ground system may take several forms; for a more complete discussion, 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 installations will be achieved via 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 MMB-** Mounting 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:
ρRF feedback (resulting in distortion on your transmitted signal);
ρUnintended frequency change;
ρBlinking or blanking of the frequency display;
ρNoise pickup; and/or
ρLoss of memory.
Note that these conditions may occur in any communications installation. The FT-857 includes extensive filtering
designed to minimize the chance of such problems; however, random currents set up by insufficient RF grounding can
nullify such filtering. Bonding the rear panel Ground lug of the FT-857 transceiver to the vehicle or vessel’s ground
system should clear up any such difficulties.
Vertex Standard does not recommend the use of “on glass” mobile antennas unless the shield 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.
FCC ID: K66FT-857

Base Station Earth Grounding
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 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 ground 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 should be made directly to the ground 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-857 rear panel.
Antenna Considerations
The antenna systems connected to your FT-857 transceiver are, of course, critically important in ensuring successful
communications. The FT-857 is designed for use with any antenna system providing a 50 Ω resistive impedance at the
desired operating frequency. While minor excursions from the 50 Ω specification are of no consequence, 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-857. 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.
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 50 Ω impedance to your transceiver on
the 1.8 ~ 50 MHz bands so long as the SWR 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 50 Ω be performed at the antenna feedpoint.

Yaesu’s Active-Tuned Antenna System (ATAS-100/-120) is a unique HF/VHF/UHF mobile antenna system, which
provides automatic tuning when used with the FT-857. See page 39 for full details on the ATAS-100/-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-857 is designed for use with an
(unbalanced) coaxial feedline. Always use a balun or other balancing device so as to ensure proper antenna system
performance.
Use high-quality 50 Ω coaxial cable for the lead-in to your FT-857 transceiver. All efforts at providing an efficient
antenna system will be wasted if poor quality, lossy coaxial cable is used. Losses in coaxial lines increase as the
frequency 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 tend to have
higher losses than larger-diameter cables, although the precise differences depend on the cable construction, materials,
and the quality of the connectors used with the cable. See the cable manufacturers・specifications for details.
For reference, the chart below shows approximate loss figures for typically- available coaxial cables frequently used in
HF installations.

Always locate antennas such that they can never come in contact with outdoor power lines in the event of a catastrophic
support or power-pole structural failure. Ground 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 cables
completely from your station if the storm is not immediately in your area. Do not allow disconnected cables to touch the
case of your FT-857 transceiver or accessories, as lightning can easily jump from the cable to the circuitry of your
transceiver via the case, causing irreparable 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 should strike your antenna structure or a
nearby power 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 storm).
The buried radials of a ground-mounted vertical antenna can carry lethal voltages outward from the center of the antenna
in the event of a direct lightning strike.
RF Field Exposure
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 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 06111 or <http://www.arrl.org>).
Although there is negligible radio frequency (RF) leakage from the FT-857 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-857, 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 (such as ferrite cores) to
FCC ID: K66FT-857
Operating Manual

10
minimize interference 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 equipment
may “comply” with RF emission standards, this does not ensure that sensitive Amateur Radio receivers like the FT-857
will not experience interference from the device!
Be certain to use only shielded cables for TNC-to-Transceiver connections. You may need to install AC line filters on the
power cord(s) of the suspected equipment, and decoupling 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 provide adequate ventilation around the cabinet of the FT-857. The
cooling system of the transceiver 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-generating device (such as a linear amplifier), and do not place
equipment, books, or papers on top of the transceiver. Place the transceiver on a hard, flat, stable surface. Avoid heating
vents and window locations that could expose the transceiver to excessive direct sunlight, especially in hot climates.
Heat Water & Moisture Dust Ventilation
Linear Amplifier Interfacing
The FT-857 provides the switching and drive-control lines required for easy interfacing to most all commonly-available
amplifiers sold today.
These include:
ρThe Antenna Jacks (“HF/50MHz” and “144/430MHz”);
ρ A T/R control line (open circuit on RX, closure to ground on TX); and
ρ A negative-going ALC jack (control voltage range: 0V to –4V DC).
ρWhen interfacing to the VL-1000 Solid State 1 KW Linear Amplifier, the optional CT-58 Interface Cable provides for
easy interconnection (requires that the Menu Mode No-020 [CAT/LIN/TUN] 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 are shown below.
Note that some amplifiers, particularly VHF or UHF “brick” amplifiers, offer two methods of T/R switching: application
of +13V or a closure to ground.
FCC ID: K66FT-857
Operating Manual
Vertex Standard Co., Ltd.
11
Be sure to configure your amplifier so that it switches via a closure to ground, as provided by your FT-857. Alternatively,
many of these amplifiers use “RF Sensing” to control their relays; if yours is not in this category, you may then use the
T/R control line from the ring of the ACC jack for control of your HF linear amplifier, if desired.
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 band-switching 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 the switching transistor in the FT-857 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 configuration
for the paddle is shown below.
For straight-key operation, only the tip and 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 used,
the key line will be constantly 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-857 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 mV, with an impedance of 600 Ω.
Adjusting the Front Feet
The two front feet of the transceiver allow the transceiver to be tilted upward for better viewing. Simply fold both feet
forward to raise the front of the transceiver, and fold them back against the bottom case to lower the front of the FT-857.

Operating Band Selection
This transceiver covers an incredibly wide frequency range, over which a number of different operating modes are used.
Therefore, this transceiver’s frequency coverage has been divided into different operating bands, each of with has its own
pre-set frequency steps and operating modes. You can change the channel steps and operating mode once you get started,
of course, per the next section.
To change the frequency band, press either the BAND(DWN) or BAND(UP) key to move to the next lower or higher
operating band, respectively.
VFOa and VFOb are independent VFOs, so they may be set to different bands. See the “Stacked VFO System” discussion
on page 22 for details.
Menu Quick Start
Many aspects of this transceiver’s configuration may be customized using the convenient “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 begins on
page 52; 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 [EXT
MENU], which Enables or Disables the “Extended Menu” Mode).
3. Rotate the DIAL knob to set this feature (in this example, the default setting is “OFF (Disabled),” so rotate the DIAL
knob to set this feature to “ON” (Enabled).
4. Press and hold in the [F] key for one second to save the new setting and exit to normal operation.
If you have momentarily pressed the [F] key to enable the changing of the function of the Multi Function keys ([A], [B],
and [C]) by the MEM/VFO CH knob.
Mode Selection
Press either the MODE(<) or MODE(>) key to move among the eight settings for the operating modes, respectively.
where “CWR” is “CW-Reverse,” using the opposite sideband from the “default” BFO injection sideband (in most cases,
the default injection sideband is on the “USB” side); “DIG” is an AFSK-based Digital mode, set up per Menu Mode No-
038 [DIG MODE]; and “PKT” represents either 1200 or 9600 bps FM packet.
You can set VFOa and VFOb to different modes in the same band, allowing you to have a “Phone” VFO and a “CW”
VFO, for example.
Adjusting the Audio Volume Level
Rotate the AF knob to set a comfortable listening level.
FCC ID: K66FT-857
Operating Manual
Vertex Standard Co., Ltd.
22
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.
Start with the AF knob set fully counter-clockwise, especially when using FM (the background noise on FM can be
surprisingly loud)!
Adjusting the RF Gain and Squelch
The SQL/RF Gain control is configured differently, depending on the country to which the FT-857 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-080 [SQL/RF GAIN]; see page 59 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 counter-clockwise; this
indicates increasing AGC voltage, which is causing the front-end gain to be reduced. In the FM and Packet modes, this
control will automatically be set to “Squelch,” even though the setting of Menu Mode No-080 [SQL/RF GAIN] is “RF
Gain.” If this control is configured for “SQL” operation, the FT-857’s RF Gain will be set for maximum sensitivity in all
modes, and the SQL/RF Gain control will function solely 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 opened by an incoming signal or noise.
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 operating frequency.
2. In the “AM/FM/PKT” modes, rotate the MEM/VFO CH knob to set the frequency. Clockwise rotation of the
MEM/VFO CH increases 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 knob to make fine frequency adjustments.
The synthesizer steps for the MEM/VFO CH knob may be adjusted independently by mode. Use Menu Mode No-006
FCC ID: K66FT-857
Operating Manual
Vertex Standard Co., Ltd.
23
[AM STEP] for AM, No-052 [FM STEP] for FM, and No-082 [SSB STEP] for SSB/CW/Digital. See pages 54, 57, and 59
for details.
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 quick frequency excursions. This can be particularly helpful on the
VHF and UHF bands.
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 54.
The main DIAL synthesizer’s tuning rate (the number of steps per rotation of the DIAL) can be adjusted using Menu
Mode No-035 [DIAL STEP]. See page 56 for details.
Stacked VFO System
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.
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 sub-band, 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.
When changing bands on either the “A” or “B” VFO, the two VFOs do not change bands together. This facilitates split-
band operation, such as on FM satellites.
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-054 [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-054 [LOCK MODE].
3. Rotate the DIAL to select the desired configuration:
DIAL: Locks DIAL knob only.
FREQ: Locks front panel keys and knobs related to frequency control (such as BAND(DWN) and BAND(UP)
key, [A](A/B) key., etc.)
PANEL: Locks all front panel keys and knobs (except POWER and LOCK keys)
FCC ID: K66FT-857

ALL: Locks all front panel keys and knobs (except POWER and LOCK keys) and microphone keys.
4. When you have made your selection, Press and hold in the [F] key for one second to save the new
setting and exit to normal operation.
When the controls are locked out, press the LOCK button once more to release them to normal operation.
IF SHIFT
The receiver’s IF SHIFT feature is an effective interference-reduction tool, which allows you to shift the passband
response higher or lower without changing the pitch of the incoming signal.
1. Press and hold in the CLAR/IF SHIFT button for one second to activate the IF SHIFT feature. An icon, such as “”,
“S” (slightly shifted to the upper side), “SS” (more shifted to the upper side), “T”(slightly shifted to the lower
side),” or “TT” (more shifted to the lower side)” icon will appear at the right of the frequency display to indicate the
IF SHIFT’s current position.
2. Rotate the CLAR knob, as needed, to reduce or eliminate the interference.
3. To turn the IF SHIFT feature off, again press and hold in the CLAR/IF SHIFT button for one second. The last setting
of the IF SHIFT control will be retained until you change it again.
If you wish to make a more permanent shift in the receiver’s IF passband, use Menu Mode No-015 [CAR LSB R] (for
LSB mode) or No-017 [CAR USB R] (for USB mode). This allows you to set up a higher or lower listening pitch, if you
prefer such as compared to the default passband response. See page 55.
AGC (Automatic Gain Control)
The receiver recovery time constant of the AGC system may be modified to match your operating needs.
1. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “l” [NB,
AGC, AUTO] appears on the display.
2. Press the [C] key to toggle the AGC recovery time constant among the following selections:
AUTO ∏ FAST ∏ SLOW ∏ AUTO ∏
where “AUTO” represents “FAST” on CW and DIG (AFSK), and “SLOW” on the voice modes.
If you disable the AGC by pressing the [B](AGC) key (to make the parentheses disappear), the S-meter (which monitors
AGC voltage) will cease to function. Depending on the setting of the RF Gain control, incoming signals will probably be
distorted if the AGC is turned off.
Noise Blanker
The IF Noise Blanker may be useful in reducing or eliminating some types of impulse noise, especially noise generated

by automotive ignition systems.
1. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “l” [NB,
AGC, OFF] appears on the display.
2. Press the [A](NB) key to activate the Noise Blanker. Parentheses will appear on both sides of the “NB” selection,
indicating that the Noise Blanker is now on.
3. To adjust the blanking level, press and hold in the [A](NB) key for one second. This instantly activates Menu Mode
No-063 [NB LEVEL], which allows adjustment of Noise Blanking Level. Rotate the DIAL knob to set a higher or
lower blanking level (on a scale of 0 to 100). When done, press and hold in the [F] key for one second to save the new
setting and return to normal operation.
4. Press the [A](NB) key again to turn the Noise Blanker off.
IPO (Intercept Point Optimization)
The IPO feature bypasses the receiver RF preamplifier, thereby eliminating the preamp’s gain. This feature is not
available on the 144 MHz and 430 MHz bands.
1. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “m” [IPO,
ATT, NAR] appears on the display.
2. Press the [A](IPO) key to bypass the receiver input preamplifier. Parentheses will appear on both sides of the “IPO”
selection, and the “IPO” icon will appear on the display. indicating that the preamp is now disengaged from the
receiver circuit.
3. Press the [A](IPO) key once more to re-activate the preamp.
On the bands below 14 MHz, the input preamplifier is rarely necessary, and activation of the IPO feature will provide
substantial protection against intermodulation and other problems associated with strong signal input to the receiver. Rule
of thumb: so long as the S-meter is moving on background noise, additional front-end gain is not necessary.
ATT (Front End Attenuator)
The Attenuator will reduce all signals (and noise) by 10 dB, and it may be used to make reception more pleasant under
extremely noisy conditions. This feature is not available on the 144 MHz and 430 MHz bands.
1. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “m” [IPO,
ATT, NAR] appears on the display.
2. Press the [B](ATT) key to activate the Attenuator. Parentheses will appear on both sides of the “ATT” selection, and
the “ATT” icon will appear on the display.
3. Press the [B](ATT) key once more to switch the Attenuator out of the receiver front end circuit. Signals will again be
received at a level 10 dB louder than was the case when the Attenuator was engaged.

・When done, press and hold in the [F] key for one second to save the new setting for the Microphone Gain.
1) The AM carrier level is preset to 25 Watts during alignment at the factory, and should not require
further adjustment. It is important to remember that AM transmission requires that power must be
distributed among the carrier and voice sidebands; therefore, if excessive carrier power is used, there
will be insufficient power available for the information-carrying voice sidebands.
2) The [TONE] switch on the back of the MH-31A8J microphone provides adjustment of the microphone’s frequency
response. Setting this switch to the “2” position will roll off some of the bass response, resulting in improved “talk
power” in many instances. The “1” position is primarily used in countries like Japan, where vowel sounds are of
critical importance in conveying information; in Western languages, consonant sounds (which are rich in high-
frequency components) are frequently more important.
VOX Operation
The VOX system provides automatic transmit/receive switching based on voice input to the microphone. With the VOX
system enabled, you do not need to press the PTT switch in order to transmit.

SRCH, PMS] appears on the display.
2. Press the [A](ARTS) key to activate ARTS™ operation.
3. Your display will change to “out range” to indicate the beginning of ARTS™ operation. Every 30 seconds, your radio
will transmit a “polling” call to the other station. When that station responds with its return ARTS™ polling signal,
your display will change to “in range” to confirm reception of the response.
4. To cancel ARTS™ operation, press the [A](ARTS) key again (the “out range” or “in range” indication will disappear
from the LCD).
ARTS Alert Beep Options
The ARTS™ feature allows two kinds of alert beeps (with the additional option of turning them off), so as to alert you to
the current status of ARTS™ operation. Depending on your location and the potential annoyance associated with frequent
beeps, you may choose the Beep mode which best suits your needs. The choices are:
RANGE: The beeps are issued only when the radio first confirms that you are within range, but does not re-confirm
with beeps thereafter.
ALL: Every time a polling transmission is received from the other station, the alert beeps will be heard.
OFF: No alert beeps will be heard; you must look at the display to confirm current ARTS™ status.
To set the ARTS™ Beep mode:
1. While still in Multi Function Row “f” [ARTS, SRCH, PMS], press and hold the [A](ARTS) key for one second. This
is a “hot key” which will instantly recall Menu Mode No-008 [ARTS BEEP].
2. Rotate the DIAL to select the desired ARTS™ Beep mode (see above).
3. When you have made your selection, press and hold the [F] key for one second to save the new setting and exit to
normal operation.

CW Identifier Setup
The ARTS™ feature includes a CW identifier, as discussed previously. Every ten minutes during ARTS™ operation, the
radio can be instructed to send “DE (your callsign) K” if this feature is enabled. The callsign field may contain up to 10
characters.
Here’s how to program the CW Identifier:
1. Press and hold the [F] key for one second to enter the Menu mode.
2. Rotate the MEM/VFO CH knob to select the Menu Mode No-010 [ARTS IDW].
3. Press the MEM/VFO CH knob momentarily to initiate callsign storage (the first character location of the callsign field
will be underlined.).
4. Rotate the DIAL knob to select the first letter/number of your callsign, then rotate the MEM/VFO CH knob one click
clockwise to save the first letter/number and move to the next entry position.
5. Repeat the previous step as many times as necessary to complete your callsign.
6. Press the MEM/VFO CH knob momentarily to save your completed callsign and exit.
7. Rotate the MEM/VFO CH knob one click counter-clockwise to select the Menu Mode No-009 [ARTS ID].
8. Rotate the DIAL to set the CW ID function to “ON.”
9. Press and hold the [F] key for one second to save the new setting and exit to normal operation.
Digital Mode Operation (SSB-Based AFSK)
The FT-857 provides extensive capability for digital mode operation on the HF, VHF, and UHF bands. The use of AFSK
(Audio Frequency-Shifted Keying) configurations allows a wide variety of different communication modes to be utilized.
The Menu provides for specific digital mode selections, which include custom BFO offsets to optimize the receive and
transmit passbands for the mode selected.
Before beginning Digital operation, you need to define which Digital mode will be utilized. To do this, use Menu #38 as
follows (in this example, we will set up RTTY as the Digital mode):
1. Press and hold in the [F] key for one second to enter the Menu mode.
2. Rotate the MEM/VFO CH knob to select Menu Mode No-038 [DIG MODE].
3. Rotate the DIAL knob to select “RTTY-L” or “RTTY-U” (see discussion below).
4. Press and hold in the [F] key for one second to save the new setting and exit.
Use this technique to set up any digital mode.
RTTY (Radio TeleType) Operation
The “RTTY” mode on the FT-857 is available in either LSB-side or USB-side BFO injection. Long-standing Amateur
FCC ID: K66FT-857
Operating Manual
Vertex Standard Co., Ltd.
39
practice calls for the use of LSB-side injection, but some applications require that you use USB-side injection.
1. Connect your TNC (Terminal Node Controller) or terminal modem to the FT-857’s rear-panel DATA jack, per the
illustration. Be sure to use the “TX AUDIO” line, not an “FSK” line, for the transmit data connection to the FT-857.
2. Press the MODE(<) or MODE(>) key, as needed, to select the DIG mode (the “DIG” icon will appear on the display).
You should now be able to tune around the band, and any RTTY signals heard should be capable of being decoded.
3. If the optional YF-122C 500 Hz filter has been installed, it may be used for RTTY work. Recall Multi Function Row
“n” [CFIL, -----, -----], then press the [B](-----) or [C](-----) key to engage the narrow filter.
4. To set up the transmit side, be sure that the Meter is set to monitor ALC voltage. If not, press the [F] key momentarily,
then rotate the MEM/VFO CH knob to select to select Multi Function Row “i” [MTR, -----, DISP], then press the
[A](MTR) or [B] key so as to select metering of ALC (“ALC” icon will appear at the upper of the [B] key).
5. Press and hold in the [F] key for one second to enter the Menu mode, then rotate the MEM/VFO CH knob to select
Menu Mode No-037 [DIG GAIN].
6. Following the instructions for your TNC’s software, activate the transmitter from the computer keyboard; this should
cause the AFSK output from the TNC to be sent to the radio. While transmitting, view the ALC meter; a few “dots” of
ALC indication should be observed. If not, rotate the DIAL knob to adjust the AFSK level within the FT-857 for
seven to eight dots of indication on the ALC meter.
7. Press and hold in the [F] key for one second to save the new AFSK level setting and return to normal
operation. You are now ready for full RTTY operation.
Because RTTY is a continuous-duty transmission mode, try to keep your transmission short when running on battery
power, so as to minimize current drain.
PSK31 Operation
Two dedicated PSK31 modes are available, one each for USB-side and LSB-side injection. For BPSK work, the injection
does not matter, but for QPSK the two working stations must use the same sideband.
Connect the FT-857 to your computer’s sound card or interface, per thenillustration.
Setup for PSK31 operation is basically identical to that previously described for RTTY operation. As before, use the
“DIG” mode. However, in Menu Mode No-038 [DIG MODE], select “PSK31-L” (for LSB injection) or “PSK31-U” (for
USB injection). As with RTTY, Menu #38 may be used to set the drive to the transmitter. And the YF-122C 500 Hz filter
may also be utilized, as described previously.
“USER” Defined Digital Modes
Also provided in the FT-857 are two convenient “USER” Digital modes, one each providing USB- and LSB-side injection,
which may be used for SSTV, Fax, Pactor, and other digital operating modes.
Here is an example involving the configuration of the USER mode for JT44 (WSJT) operation with USB-side injection
FCC ID: K66FT-857
Operating Manual
Vertex Standard Co., Ltd.
40
(as opposed to LSB injection, used in the default “RTTY” mode):
1. Use Menu Mode No-038 [DIG MODE] to set the Digital mode to “USER-U.”
2. Press the MODE(<)/MODE(>) key, as needed, to select the DIG operating mode (the “DIG” icon will appear on the
display).
3. Now use Menu mode to configure the transceiver’s passband response. Once in the Menu mode, rotate the MEM/VFO
CH knob to select Menu Mode No-039 [DIG SHIFT], and rotate the DIAL knob to set the desired BFO offset. (a
center frequency for the receiver response). For WSJT use, a setting of about “+1500” will be a good starting point.
4. Finally, depending on how you wish the display to respond, you may program in a corresponding display shift, using
Menu Mode No-036 [DIG DISP].
5. Remember to press and hold in the [F] key for one second when exiting the Menu mode.
The setup of the AFSK drive level is identical to that described previously for RTTY operation.
The USER-L and USER-U Digital modes should allow you to operate on any SSB-based AFSK Digital mode. Note that
the “PSK31” configurations will also work well for many Digital operating situations.
Packet (1200/9600 bps FM) Operation
The FT-857 is designed for operation on either 1200 bps or 9600 bps packet, and setup is similar to that described
previously for SSB-based modes. A separate Data input adjustment is provided, allowing you to optimize the deviation on
the FM Packet modes separately from the levels set for SSB-based Digital modes. The RX-Data output lines are fixed-
level outputs, not affected by the setting of the AF Gain control.
1. Connect your TNC to the FT-857’s rear-panel DATA jack, per the illustration.
Note that different connections are used for 1200 bps and 9600 bps Packet.
2. Use Menu Mode No-073 [PKT RATE] to select the desired Packet mode.
Once you have entered the Menu and have selected Menu Mode No-073 [PKT RATE], rotate the DIAL knob to select
either “1200” or “9600” (bps) as the Packet rate.
3. Press the MODE(<)/MODE(>) key, as needed, to select the PKT operating mode (the “PKT” icon will appear on the
display).
You are now set up for reception on Packet. If you are operating on 1200 bps, try now to connect to another station or
node; you may well find that the drive level needs no further adjustment. If, however, you are having trouble connecting
due to insufficient or excessive drive from the TNC to the FT-857, use Menu Mode No-071 [PKT 1200] (for 1200 bps
Packet) or No-072 [PKT 9600] (for 9600 bps Packet) to set the drive. Use your terminal software’s “test” protocol to send
out test tones, and adjust the deviation by rotating the DIAL knob, which will vary the data input level to the FT-857’s

modulator. Remember to press and hold in the [F] key for one second when adjustments are completed, so as to save the
new setting for Menu Mode No-071 [PKT 1200] or No-072 [PKT 9600].
The 9600 bps Packet deviation setting is very critical to successful operation, and it can only be accomplished using a
calibrated deviation meter; the optimum setting is usually ±2.75 kHz (±0.25 kHz). For 1200 bps, the optimum level is
much less critical, with the optimum deviation being between ±2.5 kHz and ±3.5 kHz.
WeatherFax Monitoring
Monitoring of HF WeatherFax broadcasts is easily accomplished using the FT-857.
Before proceeding, be certain that the WeatherFax demodulator is properly connected to Pins 5 and 2 of the rear panel
DATA jack.
1. Set the transceiver to the VFO mode, and set the operating mode to “DIG,” setting Menu Mode No-038 [DIG MODE]
to “PSK31-U,” as described previously.
2. Now, select the operating frequency of the station transmitting the WeatherFax broadcast. Note that, in the USB mode,
the frequency you should program onto the display is typically 1.90 kHz below the station’s “assigned” frequency.
Thus for a WeatherFax station assigned to 8.682.0 MHz, tune to 8.680.1 MHz.
3. When the WeatherFax broadcast begins, no further operator intervention should be needed from the transceiver
standpoint. The audio level from the DATA jack on the rear of the transceiver is fixed, and cannot be adjusted.
4. Fine adjustments in the gray-scale and the frame alignment are accomplished using the computer and software
connected to your WeatherFax demodulator.
Time-Out Timer
Most often used on FM, the transmitter’s Time-Out Timer (TOT) feature disables the transmitter after a user-defined
period of transmission. This feature may be useful in preventing a “stuck microphone” (accidental closure of the PTT
switch) from causing interference to other users, and it will also force you to keep your transmissions short, thereby
conserving battery power.
To activate the Time-Out Timer:
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 Menu Mode No-084 [TOT TIME].
The default setting for this feature is “OFF.” Rotate the DIAL knob to set a new time-out setting (from 1 minute to 20
minutes).
3. When you have made your selection, press and hold in the [F] key for one second to save the new setting and exit to
normal operation.

Split Frequency Operation
This transceiver provides convenient split-frequency operation, using the VFO-A and VFO-B, for DX working and other
operating situations requiring unique split frequency pairs.
The example below will describe a typical split-frequency DX situation on the 20-meter band, with a DX station
transmitting on 14.025 MHz, listening 10 kHz higher in the band.
1. Set VFO-A to 14.035.00 MHz CW (DX station’s listening frequency).
2. 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.
3. Press the [A](A/B) key momentarily to select VFO-B.
4. Tune the VFO-B frequency to 14.025.00 MHz (DX station’s transmitting frequency).
5. Press the [C](SPL) key momentarily. The transceiver will now transmit using the VFO-A frequency, and will receive
using the VFO-B frequency.
“Parentheses” will appear on the both sides of the “SPL” indication, and the “SPL” icon will appear at the upper left
corner of the display.
6. To listen to the pile-up calling the DX station (so as to align your frequency more closely to that of the station being
worked by the DX), press the [A](A/B) key to reverse the VFOs. You will now be tuning in the vicinity of 14.035
MHz, and you can zero in on the DX station’s listening frequency by tuning in on the station in QSO with the DX.
Press the [A](A/B) key again to return to reception on the DX station’s frequency.
7. Press the [C](SPL) key once more to cancel split operation; the “Parentheses” and “SPL” icon will disappear from the
display.
Active-Tuning Antenna System (ATAS-100/-120) Operation
The optional ATAS-100/-120 Active-Tuning Antenna System provides operation on a number of HF bands (7/14/21/28
MHz) plus 50 MHz, 144 MHz, and 430 MHz. The FT-857 provides microprocessor control of the tuning mechanism in
the ATAS-100/-120 for convenient automatic tuning.
Before operation can begin, you must instruct the FT-857’s microprocessor that the ATAS-100/-120 is being used. This is
done using the Menu Mode:
1. Press and hold in the [F] key for one second to activate the Menu mode.
2. Rotate the MEM/VFO CH knob to recall Menu Mode N0-085 [TUNER/ATAS]. The default setting for this Menu is
“OFF.” Rotate the DIAL to change the setting to “ATAS (ALL),” if you are using the ATAS-100/-120 for all bands
(you must connect an external diplexer to combine the two antenna ports so as to use the ATAS-100/-120 on all
bands). Or make the setting “ATAS (HF&50),” if you are using the ATAS-100/-120 on 7 ~ 50 MHz, with a dual-band
VHF/UHF antenna connected separately to the 144/430 MHz antenna port. If you are just using the ATAS-100/-120
on the HF bands only, with a dual-band VHF/UHF antenna connected separately to the 144/430 MHz antenna port (no
FCC ID: K66FT-857

43
50 MHz operation) make the setting “ATAS (HF).”
3. Press and hold in the [F] key for one second to save the new setting and exit to normal operation.
Automatic Tuning
1. Press the [F] key, as needed, to recall Multi Function Row “k” [TUNE, DOWN, UP].
2. Press the [A](TUNE) key to turn the ATAS-100/-120 on (this action only supplies voltage to the antenna at this point;
re-tuning does not begin). “Parentheses” will appear on the both sides of the “TUNE” indication, and the “ATAS” will
appear on the LCD.
3. Now press and hold in the [A](TUNE) key for one second to initiate ATAS-100/-120 tuning. The transmitter will
automatically be activated, a carrier will be sent, and the antenna’s length will be adjusted for best SWR.
4. If the microprocessor determines that the antenna’s length is radically incorrect from the optimum value, no carrier
will be sent out. Instead, in the receive mode, the antenna will retract to its shortest position (this may take up to one
minute). While this is happening, do not press the [A](TUNE) key again.
When the ATAS-100/-120 reaches its minimum length, automatic tuning will be initiated, and the
transmitter will automatically shut off when a satisfactory SWR is achieved.
5. On the 144 MHz and 430 MHz bands, the ATAS-100/-120 does not require a tuning process. SWR will be
satisfactory when the antenna is fully retracted.
6. When you wish to conclude ATAS-100/-120 operation, press the [A](TUNE) key; the “Parentheses” disappear
surrounding the “ATAS” indication.
Manual Tuning
In some instances, the SWR may be slightly improved by manual adjustment of the antenna position. This may be needed
for operation on bands like 40 meters, where the “Q” of the ATAS-100/-120 is high, causing a narrow resonance range.
Before Manual Tuning, press the [F] key, as needed, to recall Multi Function Row “i” [MTR, -----, DISP], then press the
[A](MTR) or [B] key to change the meter function to the SWR meter (“SWR” icon will appear at the upper of the [B]
key).
To tune the ATAS-100/-120 manually, recall Multi Function Row “k” [TUNE, DOWN, UP], then press and hold in the
microphone PTT switch. With the transceiver in the “transmit” mode, press and hold in the [C](UP) key (to raise the
antenna) or the [B](DOWN) key (to lower the antenna). While you hold in one of these keys, the FT-857 will generate a
carrier, and you may watch the top scale of the FT-857’s meter, looking for the meter indication to reach its minimum
value. When this is reached, release the [C](UP) or [B](DOWN) key, then release the PTT key to return to the “receive”
mode.
1) Once automatic matching has been successfully accomplished, you must change frequency by at least 10 kHz before
attempting automatic matching again. Within a window of ±10 kHz from a match point, the transceiver’s
FCC ID: K66FT-857
Operating Manual
Vertex Standard Co., Ltd.
44
microprocessor will ignore any command to attempt automatic matching.
2) Antenna tuning is accomplished using a “CW” carrier, although the mode indication will not change to “CW” (if you
are operating on another mode) during antenna tuning.
3) If you see a “HI SWR” on the LCD, it may mean that there is a problem in your coaxial cable (bad connection, etc.)
which is preventing successful tuning. Replace the cable, or try adding a few feet/meters of cable (to eliminate the
possibility of adverse “transformer action” in the 50 Ω cable during the tuning process).
4) If you are able to achieve an SWR of less than 2:1 via manual tuning, the FT-857 will “accept” the manual setting, and
you may then re-tune automatically when changing bands. If, however, you stop manual tuning at a non-optimum
setting (SWR >2:1), the FT-857 will not permit further automatic tuning. To refresh the setting of the ATAS-100/-120,
press the [B](DOWN) key until the ATAS-100/-120 fully retracts. You may then restart automatic tuning per the
procedures described earlier.
5) The FT-857 may also be used with the model ATAS-100 antenna, although the tuning speed of the ATAS-100 will be
slower than with the ATAS-120.
ATAS-100/-120 Operating Tips
The information below will help you derive the best performance possible from the ATAS-100/-120 Active-Tuning
Antenna System.
Grounding
It is critically important that you establish a good mechanical and RF ground connection for your ATAS-100/-120 (as
with all vertical antennas). Mobile mounts which are bolted through the vehicle’s roof, or otherwise mechanically affixed,
will usually be satisfactory. However, magnetic mounts do not provide the RF grounding necessary for good performance,
and are not recommended for use with this antenna.
Tuning Procedure
The feedpoint impedance of the ATAS-100/-120 (resistance and reactance) will necessarily vary over a wide range when
you change bands. Occasionally, the transceiver’s microprocessor will not initially be able to determine the proper
direction for the ATAS-100/-120 to travel (inward or outward) for best SWR.
To resolve this situation, the transceiver will then command the ATAS-100/-120 to retract fully to its minimum height,
and thence restart the tuning process. In this instance, the “TUNE” icon will remain on the display after you press the
[A](TUNE) key. If this happens, do not press the [A](TUNE) key repeatedly. The transceiver will remain in the receive
mode as it retracts (this may take up to one minute). Thereafter, the transmitter will be engaged, and the ATAS-100/-120
will be automatically adjusted for best SWR. The “TUNE” icon will then disappear from the LCD, and you will be ready
for operation.

External Wattmeters
If you wish to use an external wattmeter in conjunction with the transceiver and your ATAS-100/-120, please check the
wattmeter with an Ohmmeter prior to installation. Be sure there is a direct connection between the “In” and “Out” jacks of
the wattmeter (zero resistance), and also ensure that there is a completely open circuit between the center pin and shield of
the wattmeter’s output jack. Some wattmeters use a coil or other device which shorts the center pin to ground at DC, and
this type of internal wattmeter circuitry will not allow the tuning function of the ATAS-100/-120 to operate.
Operation on 30/17/12 Meters
Although the ATAS-100/-120 is not specified for operation on the above bands, and optimum operation is therefore not
guaranteed, the ATAS-100/-120 generally can be tuned successfully on these bands (some manual adjustment may be
required). Operation of the ATAS-100/-120 on these bands will not damage the antenna’s components; please feel free to
experiment on these bands, if you like.
FC-30 Automatic Antenna Tuner Operation
The optional FC-30 Automatic Antenna Tuner provides automatic tuning of a coaxial line so as to present a nominal 50 Ω
impedance to the FT-857’s HF/50 MHz antenna port.
Before operation can begin, you must instruct the FT-857’s microprocessor that the FC-30 is being used. This is done
using the Menu Mode:
1. Press and hold in the [F] key for one second to activate the Menu mode.
2. Rotate the MEM/VFO CH knob to recall Menu Mode No-020 [CAT/LIN/TUN]. The default setting for this Menu is
“CAT.” Rotate the DIAL to change the setting to “TUNER.”
3. Rotate the MEM/VFO CH knob to recall Menu Mode No-085 [TUNER/ATAS]. The default setting for this Menu is
“OFF.” Rotate the DIAL to change the setting to “TUNER.”
4. Press and hold in the [F] key for one second to save the new setting and exit.
Operation is similar to the procedure for the ATAS-100/-120:
1. Press the [F] key, as needed, to recall Multi Function Row “k” [TUNE, DOWN, UP].
2. Press the [A](TUNE) key to turn the FC-30 on. “Parentheses” will appear on both sides of the “TUNE” indication,
and the “TUNE” will appear on the LCD.
3. Press and hold in the [A](TUNE) key to initiate automatic tuning. The FT-857 transmitter will be activated, a carrier
signal will be sent out, and the coils and capacitors in the FC-30 will be selected/adjusted for optimum SWR. When
tuning is complete, the transmission will cease, and you will be ready for operation on this frequency.
Tuning data will be stored in the FC-30’s Memory system. See the discussion below for details on how this works.
FCC ID: K66FT-857

Antenna Tuner Memory System
The FC-30, working in concert with the FT-857, can store impedance matching data in its micro-computer memory, so as
to provide instant adjustment as you transmit in different areas of a particular band. A total of 100 memories are provided:
11 of these are “general” memories apportioned one per band, while the remaining 89 are allocated for specific frequency
data within the various bands, with the capability to resolve new tuning data every 10 kHz. A few guidelines should be
noted regarding the FC-30’s memory system:
Tuning data is stored when you make an active effort to store it by pressing and holding in the [A](TUNE) key for one
second. Although the tuner will automatically activate itself if it encounters more than 1.5:1 SWR, this memory will not
be stored unless you have pressed the [A](TUNE) key for one second. This allows you to store your favorite operating
frequency areas into tuner memory without tying up memory space with matching data on seldom-used frequencies.
If the FC-30 cannot resolve a satisfactory match because the SWR is above 3:1 (2:1 on the 50 MHz band), the tuning
process will stop, and no memory data will be stored. However, you may wish to move frequency a few kHz, then press
the [A](TUNE) key again for one second, as slight changes in the reactance may allow a match to be obtained. Then go
back to the original frequency and try again.
Another technique which may allow matching in some situations is to add a few feet or meters of coaxial cable on the
“antenna side” of the FC-30. This will change the impedance transformation taking place in the coaxial cable, possibly
moving the impedance presented to the FC-30 into an acceptable range. Note that this is not changing the actual antenna
SWR, but only the impedance “seen” by the FC-30’s matching circuits.
If your antenna system presents an SWR of less than 1.5:1, you may wish to turn off the antenna tuner, as full transmitter
power will be delivered to the antenna system without intervention by the FC-30.
If the impedance encountered by the FC-30 exceeds 3:1, and the “HI SWR” icon is illuminated, the microprocessor will
not retain the tuning data for that frequency, as the FC-30 presumes that you will want to adjust or repair your antenna
system so as to correct the high SWR condition.
Memory Operation
QMB (Quick Memory Bank) Channels
The “Quick Memory” Bank provides one-touch access to frequencies you want to store and recall in a hurry. You may
store a “QMB” channel into a “regular” memory later, if you like; use of the “regular” memories will be described later.
QMB Channel Storage
1. Tune in the desired frequency and set the operating mode and bandwidth. If this is an FM channel, set
up any required CTCSS/DCS and repeater shift configurations.
2. Press and hold in the V/M key until a double “beep” is heard. The second beep provides audible confirmation that the
data has been stored into the QMB memory.
FCC ID: K66FT-857
Operating Manual
Vertex Standard Co., Ltd.
47
Pressing the [A](STO) key momentarily while in Multi Function Row “c” [STO, RCL, PROC] will also store a frequency
into the QMB register.
QMB Channel Recall
1. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “c” [STO,
RCL, PROC] appears on the display.
2. Press the [B](RCL) key momentarily to recall the QMB memory. “QMB” will appear at the upper left corner on the
display.
3. Press the [B](RCL) key once more to return to the previous frequency (either a VFO frequency or a Memory
channel).
If you move the DIAL knob or MEM/VFO CH knob while in the QMB mode, you can change frequencies as if you were
in a “VFO” mode. You also can change operating mode by pressing the MODE(<) or MODE(>) key. When this is done,
“MTQMB” will appear in the display, where “MT” represents “Memory Tuning.” Press the [B](RCL) key once more to
return to the originally-stored QMB frequency.
Memory Operation on “Regular” Memory Channels
Most Memory operation will be conducted in the “regular” memory registers. There are 200 memory channels available
for storage and recall of important frequencies.
Normal Memory Storage
1. Tune in the desired frequency, and set the operating mode and bandwidth. If this is an FM channel, set up any
required CTCSS/DCS and repeater shift configurations. Standard (default) repeater shifts do not require you to utilize
the “split” frequency memory technique, described later.
2. Press the [F] key momentarily, then rotate the MEM/VFO CH, as needed, until Multi Function Row “b” [MW, SKIP,
TAG] appears on the display.
3. Press the [A](MW) key momentarily to enter the “Memory Check” mode, which is used to find an unused memory
channel. The frequency stored (if any) on the current memory channel will be shown in the display. Rotate the
MEM/VFO CH knob to select the channel number on which you wish to store the current frequency data.
4. Press and hold in the [A](MW) key for one second until you hear a double beep; the second beep confirms that the
frequency information was successfully stored.
Split-Frequency Memory Storage
You can also store “Split” frequencies, such as when operating on a repeater system not utilizing a “standard” offset. This

3. Press the [A](MW) key momentarily to enter the “Memory Check” mode, which is used to find an unused memory
channel. The frequency stored (if any) on the current memory channel will be shown in the display. Rotate the
MEM/VFO CH knob to select the channel on which you wish to store the receive frequency data.
4. Press and hold in the [A](MW) key for one second until you hear a double beep, which confirms that the Receive
frequency data is now stored.
5. Now, set the desired Transmit frequency and mode on the VFO.
6. Press the [A](MW) key momentarily; do not rotate the MEM/VFO CH knob!
While the “memory channel number” is blinking, press and hold in the PTT switch; while holding it in, press and hold
in the [A](MW) key for one second.
The double “beep” will confirm that independent Transmit frequency data is now stored. You may now release the
PTT switch.
In step 6 above, pressing the PTT switch does not activate the transmitter. It simply sends a signal to the microprocessor
that an independent Transmit frequency is being stored on the same channel as a previously-stored Receive frequency.
Memory Channel Recall
1. If you currently are in the VFO tuning mode, press the V/M key once to enter the “Memory” mode (a memory
channel number “M-nnn” will appear on the display in the space previously occupied by “VFOa” or “VFOb”).
2. To select another memory channel, turn the MEM/VFO CH knob.
3. When your memory channels are partitioned into Memory Groups via Menu Mode No-055 [MEM GROUP], it is easy
to change Memory Groups; press the MEM/VFO CH knob momentarily (a Group Number (“Ma” ~ “Mj” will blink),
then turn the MEM/VFO CH knob to step through the channels until you enter another. You may now press the
MEM/VFO CH knob once more to restrict memory channel access to the newly-selected Group.
4. Once you are operating on a memory channel, you may tune off of the originally-memorized frequency (as though
you were in the VFO mode). Just rotate the DIAL knob; the “Memory Channel Number” will be replaced by one
which indicates “MTUNE,” indicating that you have now shifted into the “Memory Tuning” mode. When operating
the Memory Tuning mode, if you find another frequency you wish to store into another memory channel, just press
the [A](MW) key momentarily, select a new memory channel via the MEM/VFO CH knob, then press and hold in the
[A](MW) key until you hear the double beep.

channel number will be replaced by “VFOa” or “VFOb.”
When operating on a “Split” frequency memory, a special “–+” indication will appear on the LCD.
Masking (“Hiding”) a Memory
Frequency data stored on a memory channel can be deleted, if desired, from any memory channel except channel “1.” The
deletion process is not a “hard” erasure, so if you erase a channel by mistake using this procedure, the memory channel
contents can be recovered.
1. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “b” [MW,
SKIP, TAG] appears on the display.
2. Press the [A](MW) key momentarily, then rotate the MEM/VFO CH knob to select the memory channel to be deleted.
3. Press the [B](MCLR) key momentarily. The frequency display field on the LCD will go blank, and the memory

4. Wait about five seconds; when the memory channel number stops blinking, the data will now be “masked” and will
not be available for operation.
5. To restore the masked frequency data, repeat the above steps. However, if you store new frequency information on a
channel containing masked data, the masked data will be over-written and lost.
6. Memory Channel 1 is used for Priority operation, and frequency information may only be over-written (not masked)
on this channel.
Memory Operation on “HOME” Channel Memories
Four Special one-touch “Home” channels are available, for special frequencies you use often. Either “simplex” or “split”
frequency/mode data may be stored in the “Home” channel locations. Special “Home” channels are available for HF (any
frequency between 1.8 and 29.7 MHz), 50 MHz, 144 MHz, and 430 MHz.
These memories may prove particularly useful for monitoring propagation beacons, providing one-touch recall of the
beacon frequency for a quick check of band conditions.

goes (without stopping on them even momentarily). These frequencies are stored in a special Smart Search ™ memory
bank, consisting of 50 memories. This feature is available on the FM and AM modes.
The Smart Search™ feature is especially helpful when traveling, as you can instantly store active FM repeater frequencies
without having to look up the frequencies in a reference book.
1. Set the SQL knob to the point where background noise is silenced. A typical setting, for effective Smart Search™
operation, will be at 12 o’clock or slightly clockwise from this position.
2. Set the VFO to the frequency on which you wish to begin the search (the Smart Search™ feature is available on the
VFO mode only).
3. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “f” [ARTS,
SRCH, PMS] appears on the display.
4. Now press the [B](SRCH) key momentarily; the blinking “SRCH” indicator will appear on the LCD, and the
transceiver will sweep upward on the current band, loading channels on which it encounters a signal strong enough to
open the squelch. All channels where activity is present (up to 50 channels) will be loaded into the Smart Search™
memories.
5. Now you can turn the MEM/VFO CH knob to select from the just-stored Smart Search™ memories. If you find
frequencies you wish to store into a “regular” memory, just follow the procedures described previously; just don’t
press the [B](SRCH) key while storing these memories, because this will disable Smart Search™ operation.
6. To disable Smart Search™ operation, press the [B](SRCH) key momentarily.
The Smart Search™ memories are so-called “soft” memories; they will be lost if you initiate a new Smart Search™ sweep
of the band.
Scanning Operation
Scanning Features
This transceiver contains a wide variety of scanning capabilities. Whether you are in the VFO mode or
one of the memory modes, scanning operation is fundamentally identical in all configurations, but with
the following differences:
ρ In the VFO mode, scanning causes the transceiver to sweep up or down the band, pausing or halting on any signal
encountered;
ρ In the Memory mode, the scanner will scan the programmed memories, and can be instructed to skip certain
memories during scanning;
ρ In the Programmable Memory Scan (PMS) mode, the scanner will scan the band within user-programmed frequency
limits.

Scanning Operation
In order for the FT-857 to scan automatically, the Squelch must be set so that the background noise is silenced, because
the command to “Stop Scanning” driven by the same circuit that causes the green “Busy” LED to light up (when noise or
a signal is received).
1. Set the SQL knob to the point where background noise is silenced. A typical setting, for effective scanning operation,
will be at 12 o’clock or slightly clockwise from this position.
2. Set the transceiver into the operating configuration in which you wish to scan (VFO or Memory; PMS will be
described later).
3. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “g” [SCN,
PRI, DW] appears on the display.
4. Press the [A](SCN) key momentarily to start upward scan (toward higher frequencies or higher memory channel
numbers).
5. Rotate the DIAL knob or MEM/VFO CH knob counterclockwise to toggle the scanning direction downward.
6. The scanner will now cause the transceiver to increment in the chosen direction until a signal is detected. When a
signal is encountered which opens the Squelch, it will do different things, depending on the operating mode:
µ In the FM/AM modes, the transceiver pauses on the signal and stays locked on its frequency for five seconds.
Thereafter, scanning will resume whether or not the other station’s transmission has ended. While the transceiver
is in the “Pause” condition, the decimal points in the frequency display area will blink. See “Scan-Resume
Choices” on next chapter for details of how to customize the resumption of scanning.
µ In the SSB/CW modes, the scanner will slow down (but wonn’t stop).
7. Press the PTT switch on the microphone to cancel scanning.
You may also press and hold in either the [UP] or [DWN] key on the microphone for one second to initiate upward or
downward scanning, respectively, if Menu Mode No-058 [MIC SCAN] is set to “ON.”
Scan-Resume Choices
Scanning operation requires that you have the FT-857’s audio squelched. The transceiver then “assumes” that the opening
of the squelch corresponds to the discovery of a signal you may wish to listen to.
Once the scan has been halted, one of three things may happen:
TIME (default action): In this mode, the transceiver pauses on the signal and stays locked on its frequency for five
seconds. Thereafter, scanning will resume whether or not the other station’s transmission has ended. The
pause time is adjustable from 1 to 10 seconds via Menu Mode No-078 [SCAN RESUME].
BUSY: In this mode, the scanner will halt until the other station’s transmission ceases (at which point the squelch will
close). One second after the squelch closes, scanning resumes automatically.
FCC ID: K66FT-857
Operating Manual
Vertex Standard Co., Ltd.
54
STOP: In this mode, the scanner will find a signal, and lock on that frequency without resuming the scan.
To choose the Scan-Resume mode:
1. Press and hold in the [F] button for one second to activate the Menu mode.
2. Rotate the MEM/VFO CH knob to select Menu Mode No-077 [SCAN MODE].
3. Rotate the DIAL knob to select the desired Scan-Resume mode.
4. Press and hold in the [F] button for one second to exit the Menu mode.
Scan Skip Programming (Memory Mode Only)
Among the memories you have programmed, there may be some stations which you do not wish to scan. For example,
broadcast signals (which are transmitted continuously) will cause the scanner to stop, and such channels may be skipped
so as to avoid this inconvenience.
To remove a channel from the scanning loop:
1. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “b” [MW,
SKIP, TAG] appears on the display.
2. Recall the memory channel to be skipped.
3. Press the [B](SKIP) key momentarily. The “hyphen” in the memory channel number will change to become a “dot;”
this shows that this channel now is not included in the scanning loop.
4. Repeat steps 2 and 3 as many times as necessary to skip all the channels you do not wish to scan.
5. Initiate memory scanning; you will observe that the channels you marked to be skipped are not included in the
scanning loop.
6. Press the PTT switch to stop the scan; you may now use the MEM/VFO CH knob to step through the channels
manually - one at a time - and you will observe that the “Skipped” channels are, nonetheless, available for recall by
manual means.
7. You may restore a previously-skipped channel to the scanning loop by selecting the channel manually, then pressing
the [B](SKIP) key momentarily so that the “dot” changes to become a “hyphen.”
“Priority Channel” Scanning
The FT-857’s scanning features include a two-channel scanning capability which allows you to operate on a VFO or
Memory channel, while periodically checking a Memory Channel “M-001” for activity. If a station is received on the
Memory Channel “M-001” which is strong enough to open the Squelch, the scanner will pause on that station in
accordance with the Scan-Resume mode set via Menu Mode No-078 [SCAN RESUME]. See page 59.
Here is the procedure for activating Priority Channel Dual Watch operation:
1. Rotate the SQL control until the background noise is just silenced, then store the frequency to be the “Priority”
channel into the Memory Channel “M-001.”
FCC ID: K66FT-857
Operating Manual
Vertex Standard Co., Ltd.
55
2. Set the FT-857 for operation on another memory channel, or on a VFO frequency.
3. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “g” [SCN,
PRI, DW] appears on the display.
4. Press the [B](PRI) key momentarily to start the “Priority” monitoring (the “P” icon will appear at the upper of the
frequency display). During Priority monitoring, the displayed frequency will shift to the Priority memory briefly
about five seconds, while the receiver check for the presence of a signal.
5. When no signal appears on the Priority memory (i.e. the squelch remains closed), you can tune, transmit and receive
on the VFO, or select and operate on other memories.
6. If a station you wish to talk with appears on the Priority channel, press the PTT switch momentarily while receiving
their signal (no transmission will occur) to halt Priority scanning. Otherwise, when a signal appears on the Priority
channel, Priority monitoring will just pause on the channel. Priority monitoring will resume.
7. To cancel Priority monitoring, press again the [B](PRI) key.
Programmable Memory Scan (PMS) Operation
To limit scanning (and manual tuning) within a particular frequency range, you can use the Programmable Memory
Scanning (PMS) feature, which utilizes 10 special-purpose memory pairs (“M-P1L/M-P1U” through “M-P5L/M-P5U”).
The PMS feature is especially useful in helping you to observe any operating sub-band limits which apply to your
Amateur license class.
PMS setup is simple to accomplish:
1. Store the upper and lower frequency limits of the desired range into the PMS memory pair (“M-PxL” and “M-PxU”)
2. Switch to the Memory mode by pressing the V/M key once, then rotate the DIAL to select the Memory channel “M-
PxL” or “M-PxU”.
3. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “f” [ARTS,
SRCH, PMS] appears on the display.
4. Press the [C](PMS) key. The “PMS-x” indication will appear at the upper left corner of the LCD, signifying that the
PMS feature is engaged. Tuning and scanning (by pressing the [A](SCN) key on the Multi Function Row “g” [SCN,
PRI, DW]) are now limited within the range between the selected PMS memory pair, keeping operation inside this
programmed range.
Example:Limit tuning & scanning to the frequency range 144.30 - 148.00 MHz
1. Press the V/M key, as necessary, to recall the VFO mode. Tune the MEM/VFO CH or DIAL knob to
144.300 MHz.
2. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “b” [MW,
SKIP, TAG] appears on the display.

3. Press the [A](MW) key momentarily, then turn the MEM/VFO CH knob to select memory channel “M-P1L.”
4. Press and hold in the [A](MW) key for one second to write the VFO frequency into “M-P1L.”
5. Now, tune the MEM/VFO CH or DIAL knob to 148.000 MHz.
Press the [A](MW) key momentarily, then turn the MEM/VFO CH knob to select memory channel “M-P1U.”
6. Press and hold the [A](MW) key for one second to write the VFO frequency into “M-P1U.”
7. Press the [F] key momentarily, then rotate the MEM/VFO CH knob one click clockwise to recall Multi Function Row
“f” [ARTS, SRCH, PMS].
7. Press the [C](PMS) key momentarily. Tuning and scanning are now limited to the 144.30 - 148.00 MHz range until
you press the V/M key to return to memory or VFO operation.
Dual Watch Operation
Dual Watch is similar, in some respects, to scanning. In Dual Watch, however, the transceiver monitors (squelched) on the
VFO-A frequency while periodically checking VFO-B for activity (or vice-versa). A typical example might be for you to
set VFO-A to 50.110 MHz, watching for DX stations who might call CQ on that frequency, while periodically checking
28.885 MHz for stations reporting band openings on 6 meters.
To activate Dual Watch:
1. Set up transmit and receive operation on VFO-A, establishing your primary monitoring frequency. Set
up the frequency to be checked periodically on VFO-B.
2. Recall VFO-A, then rotate the SQL control until the background noise is just silenced.
3. Press the [F] key momentarily, then rotate the MEM/VFO CH knob, as needed, until Multi Function Row “g” [SCN,
PRI, DW] appears on the display.
4. Press the [C](DW) key momentarily to activate Dual Watch operation (the “D” icon will appear at the upper of the
frequency display). The transceiver will continue to monitor (squelched) on the current (VFO-A) frequency, but every
five seconds will switch briefly to VFO-B frequency, looking for activity.
5. If a station is detected on the VFO-B frequency, the transceiver will pause on the VFO-B frequency (the decimal point
in the frequency will blink).
6. Press the [C](DW) key again to cancel Dual Watch operation (the “D” icon will disappear).
Note that pressing the PTT switch on the microphone does not cancel Dual Watch operation.

CAT (Computer Aided Transceiver) Operation
The FT-857’s CAT System allows the transceiver to be controlled by a personal computer. This allows multiple control
operations to be fully automated as a single mouse click, or it allows a third-party software package (such as contest
logging software) to communicate with the FT-857 without (redundant) operator intervention.
The Optional CAT Interface Cable CT-62 is a connection cable for the FT-857 and your computer. The CT-62 has a
built-in level converter, allowing direct connection from the rear panel CAT/LINEAR jack to the serial port of your
computer, without the need for an external RS-232C level converter box.
Vertex Standard does not produce CAT System operating software, due to the wide variety of personal computers,
operating systems, and applications in use today.
The information presented in this section will allow the programmer to understand the command structure and opcodes
used in the FT-857’s CAT System.
CAT Data Protocol
All commands sent from the computer to the transceiver consist of five-byte blocks, with up to 200 ms between each byte.
The last byte in each block is the instruction opcode, while the first four bytes of each block are arguments (either
parameters for that instruction, or dummy values required to pad the block out to five bytes). Each byte consists of 1 start
bit, 8 data bits, no parity bit, and two stop bits.
There are 17 instruction opcodes for the FT-857, listed in the chart on next page. Many of these opcodes are On/Off
toggle commands for the same action (e.g. “PTT On” and “PTT Off”) Most of these commands require some parameter or
parameters to be set. Irrespective of the number of parameters present, every Command Block sent must consist of five
bytes.
Accordingly, any CAT control program must construct the five-byte block by selecting the appropriate instruction opcode,
organizing the parameters as needed, and providing unused “dummy” argument bytes to pad the block to its required five-
byte length (the dummy bytes can contain any value). The resulting five bytes are then sent, opcode last, from the
computer to the FT-857 CPU via the computer’s serial port and the transceiver’s CAT/LINEAR jack.
All CAT data values are hexadecimal
Constructing and Sending CAT Commands
Example #1: Set the VFO frequency to 439.70 MHz
ρPer the CAT command table, the opcode for “Set Frequency” is 01. Placing the opcode into the 5th data bit position,
we then enter the frequency into the first four data bit positions:

43 97 00 00 01

Send these five bytes to the transceiver, in the order shown above.
Example #2: Turn the Split Mode “On”
ρPer the CAT command table, the opcode for “Split On/off” is 02. Placing the opcode into the 5th data bit position, we
then enter dummy values into all other parameter locations:

memory system is ideal for configuring a set of memories for LEO satellite work.
The example below is designed around the popular satellite UO-14, but the same principles apply to operation using AO-
27, SO-35, and other such satellites.
First, set up a table of the required operating frequencies. For UO-14, a typical setup table is shown below:
Channel # Rx Freq. Tx Freq. Notes
1 435.080 145.970.0 AOS
2 435.075 145.972.5
3 435.070 145.975.0 Mid Pass
4 435.065 145.977.5
5 435.060 145.980.0 LOS
AOS = Acquisition of Signal (Beginning of Pass)
LOS = Loss of Signal (End of Pass)
The above frequencies are nominal, and the changing frequencies reflects the Doppler Shift which occurs on such
satellites, which display rapid apparent motion relative to an earth-based observer. But if we can accommodate a set of
several frequency pairs in our memory system, frequencies that reflect the frequency relationships encountered during a
typical pass, we will have a good chance of having our frequencies properly aligned when it is time for making a QSO.
So we need to store the above frequency matrix into memories. Note that the receiving frequency and transmitting
frequency are on different bands. Therefore, we will use the “Split Frequency Memory” storage technique described on
page 42.
First, press the [F] key momentarily, then rotate the MEM/VFO CH knob to select Multi Function Row “a” [A/B, A=B,
SPL]. Press the [A](A/B) key, if necessary, to select VFOa.
Now press the BAND(DWN) or BAND(UP) key to select the 70 cm band. Check the setting of Menu Mode No-004
[AM&FM DIAL]. and set this to “ENABLE” to allow smaller frequency increments to be accommodated.
Set the VFOa operating frequency to 435.0800.00 MHz. Now press the [A](A/B) key in Multi Function Row “a” to select
VFOb, and set VFOb to 145.970.00 MHz. Again press the [A](A/B) key to return to VFOa. Be sure that both VFOs are
set to the FM mode, as well.
Press the [F] key momentarily, and rotate the MEM/VFO CH knob one click clockwise to select Multi Function Row
“b”[MW, SKIP, TAG].
Press the [A](MW) key momentarily, then rotate the MEM/VFO CH knob while the memory channel number is blinking;
select memory channel M-001, then press and hold in the [A](MW) key until you hear the double beep. We have just
stored the first downlink (earth station receiving) frequency into memory.
Press the [F] key momentarily, then rotate the MEM/VFO CH knob one click counter-clockwise to re-select Multi

Function Row “a” [A/B, A=B, SPL]. Press the [A](A/B) key to select VFOb (145.970 MHz).
Again press the [F] key momentarily, and rotate the MEM/VFO CH knob one click clockwise to re-select Multi Function
Row “b” [MW, SKIP, TAG]. Press the [A](MW) key momentarily; the “M-001” indicator will flash; press and hold in the
microphone’s PTT key, and while holding it in press the [A](MW) key until you hear the double beep. You have now
stored the uplink (earth station transmitting) frequency into the same memory register as we did previously for the
downlink frequency.
It’s now time to store the other frequencies in the matrix. Return to Multi Function Row “a” [A/B, A=B, SPL], and press
the [A](A/B) key to return to VFOa on 435.080.00 MHz. Now rotate the DIAL knob to set the frequency to 435.075.00
MHz. Press the [A](A/B) key again to select VFOb (145.970 MHz), and rotate the DIAL knob to set the frequency to
145.972.50 MHz. Press the [A](A/B) key to return to VFOa on 435.075.00 MHz.
Return to Multi Function “b” [MW, SKIP, TAG], and repeat the Split Memory storage process, selecting memory channel
M-002 this time when initially storing the 435.075 MHz receiving frequency.
Now repeat this entire process three more times, filling memory channels M-003, M-004, and M-005 with the frequencies
shown in the chart above.
When it’s time to operate, press the [V/M] key, if necessary, to recall the Memory mode, and rotate the MEM/VFO CH
knob to select channel M-001. This will be the first frequency pair to be utilized during the UO-14 window of workability
when it rises above your local horizon. The Doppler effect will cause the nominal 435.070 MHz downlink frequency to
appear higher to you, so utilize memory channel M-001 when the satellite first rises. A few minutes later, switch to M-002,
and at mid-pass switch to M-003. As the satellite recedes, switch to M-004 and then M-005 toward the end of the pass.
The MEM/VFO CH knob recall of these five channels makes Doppler tracking simple; just choose the memory channel
producing the best signal! You have already programmed an uplink frequency corresponding to the optimum downlink
frequency, so you will not need to try to make difficult VFO adjustments during the brief satellite passes.
The FM passbands used on LEO satellites are sufficiently broad that more precise frequency adjustment is not needed.
To aid in channel identification, remember that you can use Menu Mode No-056 [MEM TAG] to label each satellite
memory (for example, “UO-14a” ~ “UO-14e” for the above five channels).
A complete set of frequencies may be stored for each LEO satellite you wish to utilize, and once configured, the FT-857
provides a flexible and easy-to-use earth station capability for these popular satellites.
