ICOM IC-718

HF All Mode Transceiver

The origin of the HF Transceiver

ICOM IC-718

The HF bands allow you to communicate over long distances covering many km even to the other side of the world. With the superior performance found in the IC-718 such as wide dynamic range, high C/N ratio, and full duty operation you will find making these contacts easy. Experience the combination of the latest RF and digital technology, along with the size and simplified operation. You will see the IC-718 will be the most practical rig you will ever own. 
Front mounted loud speaker.

The Ic-718 has a speaker mounted on the front panel. With the speaker facing the operator, audio sounds can be clearly heard without impediment during operation. It is no longer necessary to manually increas the volume to try and capture audio sounds.

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-band near-by interfering signals. A well designed double conversion system to help minimize image and spurious responses for better signal fidelity, is also built-in. A newly designed PLL circuit has adopted to improve C/N ratio characteristics. The combination of the 4-element system mixer and new PLL circuit allows superior basic performance as that of a commercial grade transceiver. * Guaranteed range: 0.5-29.999999MHz

Optional DSP capability.

With the optional UT-106 installed you gain AF DSP capabilities. The DSP includes the following to give you superior receive quality in your shack, vehicle or during DX pedition.

Noise reduction.

Pulls desired AF signals from noise. Outstanding S/N ratio is achieved, providing clean audio in SSB and AM.

Automatic Notch filter.

This automatically minimizes beat signals and heterdynes while preserving the receive signal. Also, the notch frequency is automatically adjusted to follow interfering beat signals- for  example, reducing interfering beat signals. For example, reducing interference from RTTY signals during SSB operation. 

Interference rejection IF shift.

To reject interference, the IC-718 has an IF shift function which shifts the center frequency of the IF passband electronically to reduce adjacent interference.

Microphone compressor.

This feature compresses microphone audio input to increase average audio output level. The result is, that talk power is increased. The compression level is adjustable for your preference. This function is effective for long distance communication, or when propagation conditions are poor. 

RF gain control.

RF gain control is combined with the squelsch control. The RF gain adjusts minimum response receiver gain, and ignores signals weaker than the preset level providing pleasant standby, or scanning.

Ample CW features.

An electronic keyer with a variable dot/dash ratio (2.8:1 to 4.5:1) control is built in. By simply connecting a paddle, easy CW operation can be made. The CW pitch and key speed are also variable from 300-900Hz, 6-60wpm, respectively. Of couse, full break-in capability is available with the adjustable break-in delay.

VOX operation.

A VOX (voice operated transmission) is included with the IC-718. 
It provides handsfree operation but detecting audio signals from the microphone. It’s easy!

Flexible filter selection.

An optional IF filter can be installed into the transceiver to suit your operating preference.

High frequency stability.

When the optional CR-338 HIGH STABILITY CRYSTAL UNIT is installed, you get a very high frequency stability of ± 0.5 ppm.

Simple operation.

The IC-718 is equipped with a minimum number of switches and controls for superior feature selectability. The 10-key pad on the front panel to directly enter an operating frequency, or a memory channel number. The auto tuning steps function helps quick tuning activates when turning the dial quickly. And the band stacking register is very convienient when changing operating bands.

Digital S/RF meter.

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

Optional voice synthesizer.

A clear, electronically-generated voice announces operating frequency, mode and receiving signal strength level when the optional voice synthesizer unit, UT-102, is installed.
