Transmitter Operation
tiMe-Out tiMer
Most often used on FM, the transmitter’s Time-Out Timer (TOT) feature disables the
transmitter after a user-dened period of transmission. This feature may be useful in pre-
venting a “stuck microphone” (accidental closure of the PTT switch) from causing inter-
ference 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.
weatherFax MOnitOring
Monitoring of HF WeatherFax broadcasts is easily accomplished using the FT-818.
1. Before proceeding, be certain that the WeatherFax 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 WeatherFax broad-
cast. 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.
4. 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 xed, and cannot be adjusted.
Fine adjustments in the gray-scale and the frame alignment are accomplished using the
computer and software connected to your WeatherFax demodulator.

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 congurations.
2. Press and hold in the key until a double “beep” is heard. The second beep pro-
vides audible conrmation that the data has been stored into the QMB memory.
Pressing the (A/B) key momentarily while in Operating Function Row 3 [STO,
RCL, PMS] will also store a frequency into the QMB register.
QMB Channel Recall
1. Press the key momentarily, then rotate the knob, as needed, until Operating
Function Row 3 [STO, RCL, PMS] appears on the display.
2. Press the (RCL) key momentarily to recall the QMB memory. “QMB” will appear
at the upper right corner on the LCD.
3. Press the (RCL) key once more to return to the previous frequency (either a VFO
frequency or a Memory channel).
If you move the knob or 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 or key. When this is done, the “MTQMB” will appear
in the display, where “MT” represents “Memory Tuning.” Press the (RCL) key
once more to return to the originally-stored QMB frequency.

MeMOrY OperatiOn On “regular” MeMOrY channelS
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 congurations. Stan-
dard (default) repeater shifts do not require you to utilize the “split” frequency memo-
ry technique, described later.
2. Press the key momentarily, then rotate the knob, as needed, until Operating
Function Row 2 [MW, MC, TAG] appears on the display.
3. Press the (MW) key momentarily to enter the “Memory Check” mode, which is
used to nd an unused memory channel. The frequency stored (if any) on the current
memory channel will be shown in the display.
4. Rotate the knob to select the channel number on which you wish to store the
current frequency data.
5. Press and hold in the (MW) key for one second until you hear a double beep; the
second beep conrms 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 uti-
lizing a “standard” offset. This procedure may also be used for DX work on 7 MHz SSB,
etc.
1. In the VFO mode, set the desired Receive frequency and mode.
2. Press the key momentarily, then rotate the knob, as needed, until Operating
Function Row 2 [MW, MC, TAG] appears on the display.
3. Press the (MW) key momentarily to enter the “Memory Check” mode, which is
used to nd an unused memory channel. The frequency stored (if any) on the current
memory channel will be shown in the display.
4. Rotate the knob to select the channel on which you wish to store the receive fre-
quency data.
5. Press and hold in the (MW) key for one second until you hear a double beep,
which conrms that the Receive frequency data is now stored.
6. Now, set the desired Transmit frequency and mode on the VFO.
7. Press the (MW) key momentarily; do not rotate the knob!
8. While the “memory channel number” is blinking, press and hold in the PTT switch;
while holding it in, press and hold in the (MW) key for one second. The double
“beep” will conrm that independent Transmit frequency data is now stored. You may
now release the PTT switch.
In step 8 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 Operation
Memory Channel Recall
1. If you currently are in the VFO tuning mode, press the key once to enter the
“Memory” mode (a memory channel number “M-nnn” will appear on the display in
she space previously occupied by “VFOa” or “VFOb”).
2. To select another memory channel, turn the knob.
3. When your memory channels are partitioned into Memory
Groups via Menu #34, it is easy to change Memory Groups;
press the knob momentarily (a Group Number (“a”
~ “j”) will blink), then turn the knob to step through
the channels until you enter another. You may now press the
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 original-
ly-memorized frequency (as though you were in the VFO mode). Just rotate the
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 nd another frequency you wish to
store into another memory channel, just press the (MW) key momentarily, select
a new memory channel via the knob, then press and hold in the (MW) key
until you hear the double beep.
5. To exit the Memory Tuning mode, press the key as follows:
One touch of the key returns you to the original memory frequency.
A second touch of the key will cause you to exit the Memory mode and return
to the VFO mode (the memory channel number will be replaced by “VFOa” or
“VFOb”).
When operating on a “Split” frequency memory, a special “ ” indication will appear
on the LCD.

Memory Operation
Masking 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 key momentarily, then rotate the knob, as needed, until Operating
Function Row 2 [MW, MC, TAG] appears on the display.
2. Press the (MW) key momentarily, then rotate the knob to select the memo-
ry channel to be deleted.
3. Press the (MC) key momentarily. The frequency display eld on the LCD will go
blank, and the memory channel number will blink.
4. Wait about three 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, pro-
viding one-touch recall of the beacon frequency for a quick check of band conditions.
HOME Channel Storage
1. Tune the desired frequency, and set the operating mode. If this is an FM channel, set
up any required CTCSS/DCS and repeater shift congurations.
2. Press the key momentarily, then rotate the knob, as needed, until Operating
Function Row 2 [MW, MC, TAG] appears on the display.
3. Press the (MW) key momentarily to enter the “Memory Check” mode.
4. Press and hold in the key for one second. This stores the frequency data into the
“Home” channel location. As usual, you will hear a double beep to conrm the suc-
cessful storage of the frequency data.
5. If you wish to store a “Split” frequency pair into the “Home” channel, store the Re-
ceive frequency in steps 1 ~ 4 above. Now set the desired Transmit frequency.
6. Once more, press the (MW) key momentarily.
7. Press and hold in the microphone’s PTT switch; while holding the PTT switch, again
press and hold the key for one second. This stores the transmit frequency data
into the “Home” channel location.
HOME Channel Recall

Note: This operation does not function in the FM Broadcast frequencies.
The Spectrum Scope Monitor allows viewing of operating activ-
ity on 5 channels above and 5 channels below the current operat-
ing channel in the VFO mode. When the Spectrum Scope Mon-
itor 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 Spec-
trum Scope is turned off.
CHK: In this mode, the transceiver sweeps the current band one cycle every 10 seconds.
Setting the Spectrum Scope Mode
1. Press and hold in the key for one second to enter the Menu mode
2. Rotate the knob to select Menu #43 (SCOPE).
3. Rotate the knob to select the desired sweep mode (see above).
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.
Activate the Spectrum Scope
1. Set the transceiver to the VFO mode in the desired band.
2. Press the key momentarily, then rotate the knob, as needed, until Operating
Function Row 6 [SSM, SCH, ART] appears on the display.
3. Press the (SSM) key momentarily to engage the Spectrum Scope.
4. When the Spectrum Scope is in operation, the relative signal strength of stations on
channels immediately adjacent to the current frequency will be indicated on the dis-
play.
5. To disable the Spectrum Scope, press the (SSM) key once more.
The receiver’s audio output and S-meter are disabled when using the Spectrum Scope.
Spectrum Scope Monitor Operation
49FT-818 Operating Manual
Note: This operation does not function in the FM Broadcast frequencies.
The Smart SearchTM feature automatically stores frequencies where activity is encoun-
tered 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 refer-
ence book.
1. Set the knob to the point where background noise is silenced. A typical set-
ting, for effective Smart SearchTM operation, will be at 12 o’clock or slightly clock-
wise 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).
3. Press the key momentarily, then rotate the knob, as needed, until Operating
Function Row 6 [SSM, SCH, ART] appears on the display.
4. Now press the (SCH) key momentarily; the blinking “SRCH” indicator will ap-
pear 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.
5. All channels where activity is present (up to 50 channels) will be loaded into the
Smart SearchTM memories. Whether or not all 50 memories are lled, the search will
stop after one sweep.
6. Now you can turn the knob to select from the just-stored Smart SearchTM mem-
ories. If you nd frequencies you wish to store into a “regular” memory, just follow
the procedures described previously; just don’t press the (SCH) key while storing
these memories, because this will disable Smart Search™ operation (see step 7).
7. To disable Smart SearchTM operation, press the (SCH) key momentarily.
The Smart Search™ memories are so-called “soft” memories; they will be lost if you
initiate a new Smart SearchTM sweep of the band.

50 FT-818 Operating Manual
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 congurations, 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 set-
ting, for effective scanning operation, will be at 12 o’clock or slightly clockwise from
this position.
2. Set the transceiver into the operating conguration in which you wish to scan (VFO or
Memory; PMS will be described later).
8. Press the key momentarily, then rotate the knob, as needed, until Operating
Function Row [SCN, PRI, DW].
3. Press the (SCN) key momentarily to start upward scan (toward higher frequen-
cies or higher memory channel numbers).
4. Rotate the knob or knob counterclockwise to toggle the scanning direc-
tion downward.
5. 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 transceiv-
er 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).
6. 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”.
