Installation
Connecting the Supplied YHA-63 Antenna
Your FT-818 is supplied with a three-section antenna, model YHA-63 which is designed for
optimum performance on the 50 MHz, 144 MHz, and 430 MHz. It also works well on the
FM broadcast and other VHF bands. This antenna is intended for connection to the front
panel’s BNC-type antenna connector.
For HF and/or 50 MHz operation, most hikers carry their own dipole or collapsible vertical
antenna, fed by a small-diameter coaxial cable terminated in a type “M” (PL-259) plug, and
these kinds of antennas may be connected to the rear panel’s antenna connector.
The YHA-63 should be connected to the top panel’s “BNC” connector, using the following
guidelines:
 For 144/430 MHz operation (only), connect the shorter cap section to the screw post
on the top of the main antenna shaft, then screw the assembled YHA-63 onto the BNC
connector, twisting it 1/4 turn clockwise to secure the antenna.
 For 50 MHz operation, unscrew the short cap section, and replace it with the long
cap section. The long cap section will provide good results on 144/430 MHz, as well,
but those owners not using 50 MHz may prefer the shorter total length of the YHA-63
when using the short cap on 144/430 MHz.
 For shortwave listening using a random-length wire antenna for reception only, you may wish to consider
connection of the wire between the
main YHA-63 shaft and the cap,
using a “spade lug” or similar lug
on the end of the wire to provide a
secure connection between the cap
and the rest of the antenna.
 Menu #07 (“ANTENNA”) allows you
to define which connector (“Front” or
“Rear”) is used on a particular band.
See page 54 for details.

in the appropriate locations.

Installation
Alkaline Battery Installation and Use
The FT-818 is supplied with the FBA-28 holder for Alkaline “AA” cells. A fresh set of Alkaline cells should provide approximately 5.5 hours of reception under typical conditions.
1. To install or replace the AA cells, first remove the battery cover from the bottom side of
the transceiver. Slide the battery cover latch forward, as shown in the illustration, then
fold the battery cover upward and set it aside temporarily.
2. Install the Alkaline AA cells as shown in the illustration, paying particular attention to the
correct polarity of the batteries.
3. When all batteries have been successfully installed, replace the battery cover.

Important Notes
 When the transceiver is to be stored for a long period of time without use (longer
than ten days), remove the batteries from the FBA-28 holder, to avoid the possibility of battery leaking causing damage to the transceiver. Inspect the FBA28 battery holder occasionally for signs of corrosion or battery leakage, and
remove the batteries immediately if any such damage is observed.
 The FBA-28 battery holder is designed for use solely with Alkaline type “AA”
cells. Do not attempt to use Ni-MH or other rechargeable cells in the FBA-28,
because it does not contain the protection circuitry required when using rechargeable cells.
 When replacing batteries, replace all eight AA cells simultaneously with fresh
batteries.
 When the battery voltage is approaching the value which indicates depletion is
near, the small “
” will blink, indicating it is time to replace the batteries.

Installation
External Power Connections
The FT-818 may be connected to an external 13.8 Volt DC power source providing at least
3 Amps of continuous-duty current.. The supplied E-DC-6 DC cable may be used for DC
connections.
While connected to an external DC source, if you have installed the supplied SBR-32MH
Ni-MH Battery Pack, the E-DC-6 connection to the external DC power source will allow operation of the FT-818 while charging of the SBR-32MH is in progress.
When making DC power connections, be absolutely certain to follow the markings on the
E-DC-6 so as to ensure proper polarity of the connection to the power supply. Connect the
Red and Black or White and Black wire to the Positive (+) power supply terminal, and connect the Solid Black wire to the Negative (-) power supply terminal.

Operation
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 beings on page 52; for now, here is a
brief discussion on how to change Menu settings:
1. Press and hold in the
key for one second to enter the Menu mode.
2. Rotate the
knob to recall the Menu item to be changed (for example, Menu #01,
which Enables or Disables the Automatic Repeater Shift on the 144 MHz band).
3. Rotate the

Adjusting the RF Gain and Squelch
The

default function of this control is “RF Gain”. The
configuration of the
control is set via
Menu #45; see page 61 for details.

SQL/RF
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
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 an “Auto-Squelch” mode, wherein the FM/Packet squelch threshold is
preset at the factory; the
control still acts as an “RF Gain” control, however, and
it normally should be set fully clockwise.

If this control is configured for “SQL” operation, the FT-818’s RF Gain will be set for maximum sensitivity in all modes, and the
control will function solely as a Squelch
control. In this case, rotate the
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.
Note: Squelch operation does not function in the FM Broadcast frequencies.
Battery consumption is significantly reduced if the receiver is squelched, as the audio amplifier stage is shut off when the receiver is muted.

Operation
Setting the Operating Frequency
1. In the “SSB/CW/DIG” modes, rotate the
knob to set the frequency. Clockwise rotation
of the
knob increases the operating frequency.
2. In the “AM/FM/PKT” modes, rotate the
SEL
DIAL
knob to set the frequency. Clockwise rotation of
the
knob increases the operating frequency.
3. You may also use the
knob to adjust the operating frequency in the “SSB/CW/
DIG” modes. The
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
knob to make fine frequency adjustments.
4. If you press the
knob momentarily, then rotate the
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.
5. In step 2 above, it was mentioned that tuning in the “AM/FM/PKT” modes is accomplished using the
knob. By default, the
knob is disabled in these modes; if
you wish to enable the
knob in these modes, use Menu #04; see page 54.
6. The synthesizer steps for the

(Auto Range Transpond System) Operation

The ARTS system uses DCS signaling to inform you when you and another ARTS™equipped station are within communications range. This can be especially valuable during
search-and-rescue operations, as a base station can quickly use ARTS™ to alert a field
unit that it is out of range; the field unit can then move to a better location to re-establish
communications.

option that is best for your operating needs.

CW Identifier Setup

The ARTS™ feature includes a CW identifier. When it is activated, the radio will send “DE
(your callsign) K” in Morse code every ten minutes during ARTS™ operation.
To program the CW IDer, use Menu #31 (ID), as described on page 58. And to activate
the CW IDer, use Menu #18 (CW ID).

Transmitter Operation

Digital Mode Operation (SSB-Based AFSK)

The FT-818 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 #26 as follows (in this example, we will set up RTTY as the Digital
mode):
1.
2.
3.
4.

Press and hold in the
key for one second to enter the Menu mode.
Rotate the
knob to select Menu #26 (DIG MODE).
Rotate the
knob to select “RTTY”.
Press and hold in the
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-818 is based on LSB-side carrier injection, in accordance
with long-standing amateur practice. If you need USB-side injection for your application,
see the “User” mode discussion below.
1. Connect your TNC (Terminal Node Controller) or terminal modem to the FT-818’s
rear-panel DATA jack, per the illustration.
2. Press the
/
key, as needed, to select the DIG mode (the “DIG”
icon will appear on the display). Be certain to use the “TX Audio” line from your TNC,
not an “FSK Key” line, for the transmit-data connection.
3. Press the
/
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.

7. 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
knob to adjust the AFSK level. Press and hold in the
key for one second to save the new AFSK level setting and return to normal operation. You are now ready for 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-818 to your computer’s sound card or interface.
Setup for PSK31 operation is basically identical to that previously described for RTTY
operation. As before, use the “DIG” mode. However, in Menu #26, select “PSK31-L” (for
LSB injection) or “PSK31-U” (for USB injection). As with RTTY, Menu #25 may be used to
set the drive to the transmitter. And the YF-122C 500 Hz filter may also be utilized, as described previously.

Transmitter Operation
“USER” Defined Digital Modes

Also provided in the FT-818 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 RTTY with USB-side
injection (as opposed to LSB injection, used in the default “RTTY” mode):
1. Use Menu #26 to set the Digital mode to “USER-U”.
2. Press the
/
key, as needed, to select the DIG mode (the “DIG”
icon will appear on the display).
3. Now use Menu #27 to configure the transceiver’s passband response. Once in the
Menu mode, rotate the
knob to select Menu #27 (DIG SHIFT), and rotate the
knob to set the desired BFO offset (depending on how your TNC’s tones are set
up). For typical high-frequency tone use, a setting of about “+2100” 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 #24 (DIG DISP). Remember to press and hold in
the
key for one second when exiting the Menu mode.
5. 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 SSBbased AFSK Digital mode. Note that the “PSK31” configurations will also work well
for many Digital operating situations.

Transmitter Operation

Packet (1200/9600 bps FM) Operation

The FT-818 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 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-818’s rear-panel DATA jack, per the illustration. Note that
different connections are used for 1200 bps and 9600 bps Packet.
2. Use Menu #40 (PKT RATE) to select the desired Packet mode. Once you have entered
the Menu and have selected Menu #40, rotate the
knob to select either “1200” or
“9600” (bps) as the Packet rate.
3. Press the
/
key, as needed, to select the PKT mode (the “PKT”
icon will appear on the display).
4. 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.
5. If you are having trouble connecting due to insufficient or excessive drive from the TNC
to the FT-818, use Menu #39 (PKT MIC) to set the drive. Use your terminal software’s
“test” protocol to send out test tones, and adjust the deviation by rotating the
knob, which will vary the data input level to the FT-818’s modulator. Remember to press
and hold in the
key for one second when adjustments are completed, so as to save
the new setting for Menu #39.
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.

Transmitter Operation
AM Transmission
The FT-818 utilizes low-level amplitude modulation of an early stage for transmission purposes. This capability is primarily provided for emergency use only, as low-power operation typically utilizes more efficient transmission/reception modes.
The AM carrier level is preset to 2 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.
The AM microphone gain is preset at the factory to a value which typically provides good
audio. If you need to modify the microphone gain in the AM mode, use Menu #05 (AM
MIC). See page 54 for details.

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.

Transmitter Operation
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 transmission short, thereby conserving
battery power.
To activate the Time-Out Timer:
1. Press and hold in the
key for one second to enter the Menu mode.
2. Rotate the
knob to recall Menu #49 (TOT TIME).
3. The default setting for this feature is “off”. Rotate the
knob to set a new time-out
setting (from 1 minute to 20 minutes).
4. When you have made your selection, press and hold in the
key for one second to
save the new setting and exit to normal operation.

Weather Fax Monitoring
Monitoring of HF Weather Fax broadcasts is easily accomplished using the FT-818.
1. Before proceeding, be certain that the Weather Fax demodulator is properly connected
to Pins 5 (DATA OUT 1200bps) and 2 (GND) of the rear panel DATA jack.
2. Set the transceiver to the VFO mode, and set the operating mode to “DIG,” setting
Menu #26 to PSK31-U, as described previously.
3. Now, select the operating frequency of the station transmitting the Weather Fax 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 Weather Fax
station assigned to 8.682.0 MHz, tune to 8.680.1 MHz.
4. When the Weather Fax 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.
Fine adjustments in the gray-scale and the frame alignment are accomplished using the
computer and software connected to your Weather Fax demodulator.

Memory Operation
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.

Spectrum Scope Monitor Operation
Note: This operation does not function in the FM Broadcast frequencies.
The Spectrum Scope Monitor allows viewing of operating activity
on 5 channels above and 5 channels below the current operating
channel in the VFO mode. When the Spectrum Scope Monitor
is activated, the display indicates the relative signal strength on
channels immediately adjacent to the current operating frequency.
Two basic operating modes for Spectrum Scope are available:
CONT: In this mode, the transceiver sweeps the current band repeatedly until the Spectrum Scope is turned off.
CHK: In this mode, the transceiver sweeps the current band one cycle every 10 seconds.

Smart Search™ Operation
Note: This operation does not function in the FM Broadcast frequencies.
The Smart SearchTM feature automatically stores frequencies where activity is encountered
on the current band. When Smart SearchTM is engaged, the transceiver quickly searches
above your current frequency, storing active frequencies as it goes (without stopping on
them even momentarily). These frequencies are stored in a special Smart SearchTM memory bank, consisting of 50 memories. This feature 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
knob to the point where background noise is silenced. A typical setting, for effective Smart SearchTM 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
SearchTM feature is available on the VFO mode only).

Scanning Operation
Note: This operation does not function in the FM Broadcast frequencies.
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:
 In the VFO mode, scanning causes the transceiver to sweep up or down the band,
pausing or halting on any signal encountered;
 In the Memory mode, the scanner will scan the programmed memories, and can be
instructed to skip certain memories during scanning;
 In the Programmable Memory Scan (PMS) mode, the scanner will scan the band
within user-programmed frequency limits.

Scanning Operation
1. Set the
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).

4. Press the
or higher memory channel numbers).
5. Rotate the
knob or
knob counterclockwise to toggle the scanning direction

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, In the FM/
AM modes, the scanner will pause until the signal disappears (at the end of the other
station’s transmission), at which point scanning will resume. While the transceiver is in
the “Pause” condition, the decimal points in the frequency display area will blink. See
“Scan-Resume Choices” on the next page for details of how to customize the resumption of scanning, In the SSB/CW modes, the scanner will slow down (but doesn’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
1/2 second to initiate upward or downward scanning, respectively, if Menu #37 (MIC
SCAN) is set to “ON”.

Scanning Operation
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
key momentarily, then rotate the
knob, as needed, until Operating
Function Row 2 [MW, MC, TAG] appears on the display.
2. Recall the memory channel to be skipped.

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
Memory Skip “ON”
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
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
(MC) key momentarily so that the “dot” changchannel manually, then pressing the
es to become a “hyphen”.
Scan-Resume Choices
Scanning operation requires that you have the transceiver’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, the transceiver pauses on the signal and stays
locked on its frequency for five seconds (default pause time). Thereafter, scanning
will resume whether or not the other station’s transmission has ended. The scan
resume interval can be set to 3/5/10 seconds, or off ( whereby scanning quits when
a signal is received) via Menu #41 (RESUME); see 60 for details.

Scanning Operation
Programmable Memory Scan (PMS) Operation
To limit scanning (or tuning) within a particular frequency range, you can use the Programmable Memory Scanning (PMS) feature, which utilizes special-purpose memory pair (“MPL” and “M-PU”). 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-PL” and “M-PU”).
2. Press the
key momentarily, then rotate the
knob, as needed, until Operating
Function Row 3 [STO, RCL, PMS] appears on the display.

1. Press the
key, as necessary, to recall the VFO mode. Tune the
knob or

144.300 ~ 148.000-MHz range until you press the
key to return to memory or VFO

Note
The frequency resolution for these sub-band limits is 100 kHz, although the channel resolution of the sub-band limit memories in whatever you have selected as
the current step size. As a result, the frequencies stored in these special memories
(M-PL and M-PU) are both rounded down to the nearest 100 kHz for their roles as
sub-band limits. Therefore, in the above example, any frequency between 144.300
and 144.399 MHz may be used to store a lower tuning limit of “144.300 MHz” in
memory M-PL.

Dual Watch Operation
Note: This operation does not function in the FM Broadcast frequencies.
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
control until the background noise is just silenced.
3. Press the
key momentarily, then rotate the
knob, as needed, until Operating
Function Row 5 [SCN, PRI, DW] appears on the display.
4. Press the
(DW) key momentarily to activate Dual Watch operation (the “DW” icon
will appear at the bottom left corner of the LCD.
5. 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.
6. 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).
7. Press the
(DW) key again to cancel Dual Watch operation (the “DW” icon will disappear).
Note that pressing the PTT switch on the microphone does not cancel Dual Watch
operation.

Operation on Alaska Emergency Frequency: 5167.5 khz (U.S. Version Only)
Section 97.401(d) of the regulations governing amateur radio in the United States permit
emergency amateur communications on the spot frequency of 5167.5 kHz by stations in (or
within 92.6 km of) the state of Alaska. This frequency is only to be used when the immediate safety of human life and/or property are threatened, and is never to be used for routine
communications.
The FT-818 includes the capability for transmission and reception on 5167.5 kHz under
such emergency conditions via the Menu system. To activate this feature:

Press the
knob to select the emergency channel (M-EMG), which is found between channels
M-PU and M-001.
Note that the receive-mode Clarifier functions normally while using this frequency, but
variation of the transmit frequency is not possible. Activation of Menu #28 does not enable
any other out-of-amateur-band capability on the transceiver. The full specifications of the
FT-818 are not necessarily guaranteed on this frequency, but power output and receiver
sensitivity should be fully satisfactory for the purpose of emergency communication.
If you wish to disable operation on the Alaska Emergency Frequency, repeat the procedure detailed above, but set Menu #28 to “OFF” in step 3 of the procedure.
In an emergency, note that a half-wave dipole cut for this frequency should be approximately 45’3” on each leg (90’6” total length).
Emergency operation on 5167.5 kHz is shared with the Alaska-Fixed Service. This transceiver is not authorized for operation, under the FCC’s Part 87, for aeronautical communications.

Cloning
You can transfer all data stored in one transceiver to another set by utilizing the handy
“Cloning” feature. This requires a user-constructed cloning cable which connects the ACC
jacks on the two transceivers as shown below.
To clone from one transceiver to another, use the following procedure:
1. Insert the Clone Cable into the ACC jack of each transceiver.
2. Turn both transceivers off, then press and hold in the
and
keys on each radio while turning the
power on again. The “CLONE MODE” notation will appear on
the display.
3. On the “destination” radio, press the
key.
4. Now, on the “source” radio, press the
key. Data will now
be transferred to the “Destination” radio from the “Source” radio.
5. If there is a problem during the cloning process, “Error” will be
displayed. Check your cable connections and try again.
6. If cloning is successful, turn the “destination” radio off. Now
turn the “source” radio off.

Distination radio

Source radio

Remove the clone cable. Channel and operating data for both radios are now identical.
They both may be turned on now for normal operation.
When the radio is “Large Character” mode, the radio does not display the “CLONE
MODE” which indicates the “clone mode”. However, the clone operation is the same
method.

CAT System Programming
The FT-818’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-818 without (redundant) operator intervention.
The Optional USB Interface Unit SCU-17 may be used for CAT control of the transceiver
with a computer via a USB connection.
The Optional CAT Interface Cable CT-62 is a connection cable for the FT-818 and your
computer. The CT-62 has a built-in level converter, allowing direct connection from the rear
panel ACC jack to the serial port of your computer, without the need for an external RS232C level converter box.
Yaesu Musen does not produce CAT System operating software, due to the wide variety of
personal computers, operating systems, and applications in use today. However, the FT818 (and other Yaesu products) are widely supported by third-party software packages,
and we recommend that you contact your dealer for advice, or check advertisements in
amateur radio journals. Most software vendors also have Home Pages on the World Wide
Web which contain a wealth of information on the features and radio support for their software packages.

CAT System Programming
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.

CAT 5-BYTE COMMAND STRUCTURE

There are 17 instruction opcodes for the FT-818, 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” Eargument 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-818 CPU via the computer’s serial port and the transceiver’s ACC
jack.
All CAT data values are hexadecimal.

Constructing and Sending CAT Commands
Example #1: Set the VFO frequency to 439.70 MHz
Per 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:

Example #2: Turn the Split Mode “On”
Per 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:
