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 timeout 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 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.
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 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 WeatherFax demodulator.

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.

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
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.
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 configurations.

frequency or a memory channel).

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).

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.

Smart SearchTM memories. Whether or not all 50 memories are filled, the search will
stop after one sweep.

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).
8. Press the
key momentarily, then rotate the
knob, as needed, until Operating
Function Row [SCN, PRI, DW].
(SCN) key momentarily to start upward scan (toward higher frequen3. Press the
cies or higher memory channel numbers).
4. Rotate the
knob or
knob counterclockwise to toggle the scanning direction 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 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).
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”.
