Description
ICOM IC-718 HF All Band Transceiver
System Overview
With the superior performance found in the Icom IC-718, The HF bands allow you to communicate over long distances covering many km even to the other side of the world. 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.
Functions
Front-mounted loudspeaker
The IC-718 has a speaker mounted on the front panel. With the speaker facing the operator, audio sounds can be heard without impediment during operation. It is no longer necessary to manually increase 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 nearby 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 been 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: 0.5–29.999999 MHz
Optional DSP capability
With the optional UT-106* installed you gain AF DSP capabilities. The DSP includes the following to give you superior quality in your shack. * Already installed with some versions.
Noise reduction:
Pulls desired AF signals from noise. An outstanding S/N ratio is achieved, providing clean audio in SSB and AM.
Automatic Notch Filter:
This 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 the 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
RF gain control is combined with the squelch control. The RF gain adjusts minimum response receiver gain, and ignores signals weaker than the pre-set level— providing pleasant stand-by, 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 the key speed are also variable from 300–900 Hz, and 6–60 wpm, respectively.
Of course, 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 hands-free operation by detecting audio signals from the microphone.
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.
Selectable antenna tuner
Either the AT-180 or AH-4 optional antenna tuner can be used with the IC-718 to suit your installation conditions or operating style. Of course, the AH-4 control circuit is built into the IC-718.
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 directly enters an operating frequency or a memory channel number. The auto-tuning steps function helps quick tuning activate when turning the dial quickly.
The band stacking register is very convenient when changing operating bands.
Digital S/RF meter
Built-in multi-functional digital S/RF meter indicates signal strength level while receiving, and either transmits output power, ALC level, or VSWR ratio while transmitting.
Optional automatic tuning antenna
The optional vehicle mount automatic tuning antenna, AH-740 provides relay-driven high-speed tuning covering from 2.5 to 30MHz.
Its IP55 dust protection and water jet resistance ensure reliable operation in harsh weather conditions.
