HF ALL BAND TRANSCEIVER|718

The Long-Selling HF Transceiver
Now Improved Even MoreFront Mounted Speaker
The IC-718 has a speaker mounted on
the front panel. With the speaker facing
the operator, audio sounds can beclearly heard without impediment during
operation.

Superior Basic Performance
The IC-718 has 0.03 ~ 29.999999 MHz*
general coverage receive capability.
A 4-element system is employed for the
1st receive mixer, providing superior
receive IMD, especially from in-bandnear-by interfering signals. A welldesigned double-conversion system
to help minimize image and spurious
responses for better signal fidelity, isalso built-in. Its PLL circuit improves
C/N ratio characteristics. PLL circuit
has been adopted to improve C/N ratio
characteristics. The combination of the4-element system mixer and new PLL
circuit allows superior basic performanceas that of a commercial grade transceiver.
* Guaranteed range: 0.5 ~ 29.999999 MHz

Noise Reduction Function*
The Noise Reduction pulls desired AF
signals from noise. Outstanding S/N ratio
is achieved, providing clean audio in SSBand AM.
* USA version only.
Comparison of receive signal speaker output
Noise reduction OFF

Noise reduction ON

The IC-718 has a low distortion
microphone compressor. This featurecompresses microphone audio input toincrease average audio output level.
The result is that talk power is increased.
This function is effective for long distancecommunication, or when propagation
conditions are poor.

THE ORIGIN OF
THE HF TRANSCEIVER

RF Gain Control

The IC-718 is a compact rig with ample features for

Five Selectable IF Filter Widths

Simple Operation

The RF gain adjusts minimum response
receiver gain, and ignores signals weaker
than the preset level — providing pleasantstandby, or scanning operation.
It is combined with the squelch control.

HF communications. The HF bands enable you toThe FPGA (Field Programmable Gate Array)
digital filtering system has been adopted.
Two standard IF widths are available, andthe third width can be selected from the fiveto suit your style of operation.

The IC-718 is equipped with a minimum
number of buttons and knobs for superiorfeature selectability. Use the 10-key padon the front panel to directly enter anoperating frequency, or a memory channelnumber. The auto tuning steps functionhelps quick tuning activates when quickly
turning the dial. And the band stacking
register is very convenient when changing
operating bands.

Microphone Compressor

Ample CW Features
An electronic keyer with a variable dot/dash ratio (2.8:1 to 4.5:1) control is builtin. By simply connecting a paddle, easy
CW operation can be made. The CW pitch
and the key speed are also variable from300 ~ 900 Hz, 6 ~ 60 wpm, respectively.
Of course, full break-in capability isavailable with an adjustable break-in delay.

Digital S/RF Meter
Built-in multi-functional digital S/RF meter
indicates signal strength level whilereceiving, and either transmit output power,
ALC level or VSWR ratio while transmitting.

communicate across long distances, even reaching theother side of the Earth. With its wide dynamic range,high S/N ratio, and full duty operation, you will makecontacts easily. Experience the combination of RF anddigital technology and you will realize the IC-718 is themost practical rig for your needs.

Optional Automatic Antenna Tuner* 6 kHz: Wide standard filter
2.4 kHz: Normal (Narrow for AM) standard filter

HF ALL BAND TRANSCEIVER|718

Easy VOX Operation
A VOX (voice operated transmission)is included with the IC-718. It provides
hands-free operation by detecting audio
signals from the microphone.

The optional automatic antenna tuner,
AH-730 performs tuning operations at ahigh speed of about 2 to 3 seconds. When
you change the operation band, band
information is transferred to the tuner andautomatically matches to the antenna.

Optional Automatic Tuning
Antenna AH-740
The optional vehicle mount automatictuning antenna provides relay-driven highspeed tuning from 2.5 to 30 MHz. Its IP55
dust-protection and water jet resistanceensures reliable operation in harshweather conditions.

Other Features
Automatic Notch Out of the Filter*
The Notch Filter function automaticallyminimizes beat signals and heterodynes
while preserving the received signal.
Also, the notch frequency is automaticallyadjusted to follow interfering beat signals.
For example, reducing interference from
RTTY signals during SSB operation.
* USA version only.

Interference Rejection — IF Shift
To reject interference, the IC-718 has anIF Shift function which shifts the center
frequency of the IF passband electronicallyto reduce adjacent interference.
