Classic Simplicity, Compact, and Timeless Reliability

The IC-718 is a compact rig with ample features for HF communications. The HF bands enable you to communicate across long distances, even reaching the other side of the Earth. With its wide dynamic range, high S/N ratio, and full duty operation, you will make contacts easily. Experience the combination of RF and digital technology and you will realize the IC-718 is the most practical rig for your needs.

Five Selectable IF Filter Widths

6 kHz: Wide standard filter
2.4 kHz: Normal (Narrow for AM) standard filter

The FPGA (Field Programmable Gate Array) digital filtering system has been adopted. Two standard IF widths are available, and a third width can be selected from five to suit your style of operation and no need to purchase a filter.

Front Mounted Loud Speaker

The IC-718 has a speaker mounted on the front panel. With the speaker facing the operator, the audio can be clearly 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-band nearby interfering signals. Also built-in is a well-designed double-conversion system to help minimize image and spurious responses for better signal fidelity. The PLL circuit has been adopted to improve C/N ratio characteristics. Combining the 4-element system mixer and new PLL circuit allows superior basic performance as a commercial-grade transceiver.
* Guaranteed range: 0.5 ~ 29.999999 MHz.

Noise Reduction Function*

The Noise Reduction pulls desired AF signals from noise, which achieves an outstanding S/N ratio for clean audio in SSB and AM.

*USA version only.

Automatic Notch Out of the Filter*

The Notch Filter function automatically minimizes beat signals and heterodynes while preserving the received signal. Also, the notch frequency is automatically adjusted to follow 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 electronically shifts the IF passband's center frequency to reduce adjacent interference.

Microphone Compressor

The IC-718 has a low-distortion microphone compressor. This feature compresses microphone audio input to increase the average audio output level, increasing talk power. This function is effective for long-distance communication or when propagation conditions are poor.

RF Gain Control

The RF gain adjusts the minimum response receiver gain, ignoring signals weaker than the preset level — providing pleasant standby or scanning operations. RF gain control is combined with the squelch control.

Ample CW Features

Built-in is an electronic keyer with a variable dot/dash ratio (2.8:1 to 4.5:1) control. By simply connecting a paddle, easily use CW operations. The CW pitch and the key speed vary from 300 ~ 900 Hz to 6 ~ 60 wpm, respectively. Of course, full break-in capability is available with an adjustable break-in delay.

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.

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.

Simple Operation

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

Optional Automatic Antenna Tuner

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

Optional Automatic Tuning Antenna AH-740

The optional vehicle mount automatic tuning antenna provides relay-driven highspeed tuning from 2.5 to 30 MHz. Its IP55 dust protection and water jet resistance ensure reliable operation in harsh weather conditions.
