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.
Superior Basic Performance
The IC-718 is a long-standing HF radio, with over 150000 units*1 produced since its launch. It is renowned for its simple, user-friendly operation and reliable basic performance, making it popular among both new and experienced operators. The well-designed receiver system minimizes image and spurious responses, ensuring better signal fidelity, while delivering superior receiver IMD, particularly against nearby in-band interference. The general coverage receiver spans from 0.03 to 29.99999 MHz*2 continuously in SSB, AM, and CW modes. Additionally, the IC-718 is rugged enough to meet MIL-810-STD environmental testing standards.

Noise Reduction Function
The Noise Reduction pulls desired AF signals from noise. Outstanding S/N ratio is achieved, providing clean audio in SSB and AM.
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 shifts the center frequency of the IF passband electronically to reduce adjacent interference.
Microphone Compressor
The IC-718 has a low distortion microphone compressor. This feature compresses microphone audio input to increase average audio output level. The result is that talk power is increased. This function is effective for long distance communication, or when propagation conditions are poor.
RF Gain Control
The RF gain adjusts minimum response receiver gain and ignores signals weaker than the preset level — providing pleasant standby or scanning operation. It is combined with the squelch control.
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 the key speed are also variable from 300 ~ 900 Hz, 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.
Built-in Voice Synthesizer
Built-in voice synthesizer announces the operating frequency, mode and S-meter level in clear electronically generated voice in English. Audio level, speed, and contents are adjustable in the SET mode.
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 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.
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 directly enter an operating frequency, or a memory channel number. The auto tuning steps function helps quick tuning activates when quickly turning the dial. And 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 ensures reliable operation in harsh weather conditions.

CloseCloseIngress Protection (IP) Code
Ingress Protection (IP) ratings define the level of protection provided by enclosures to prevent the ingress of foreign objects (dust) and liquid into the electrical equipment.
International Standard IEC 60529 outlines an international classification system that describes the sealing characteristics of electrical equipment.
The classification system uses the “IP” code, or “Ingress Protection” code, to define the level of seal.
An IP number contains two numbers (i.e. IP67) in most instances which relate to the level of protection provided by an enclosure or housing.
Either number may be shown as “X” (i.e. IPX6 / IP7X) to indicate the “X” part is not tested.
Degrees of Solid Particle Protection – 1st Digit
| IP6x | No ingress of dust; complete protection against contact. (Dust tight) |
|---|---|
| IP5x | Protected from the amount of dust that would interfere with normal operation. (Dust protected) |
Degrees of Liquid Ingress Protection – 2nd Digit
| IPx8 | Protected against continuous immersion in water. Depth and duration specified by model. |
|---|---|
| IPx7 | Protected against temporary immersion in water for 1 m (3.3 ft) for 30 minutes |
| IPx6 | Protected against water projected by powerful jets from any direction. 100 L per minute by a powerful jets (12.5 mm) for 3 minutes. |
| IPx5 | Protected against water projected by jets from any direction. 12.5 L per minute by a nozzle (6.3 mm) for 3 minutes. |
| IPx4 | Protected against water splashed against the equipment from any direction |
