Icom IC-718 Base Station Amateur Transceiver Radio (discontinued)

Further details of Icom IC-718 Base Station Amateur Transceiver Radio

• 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 increase the volume to try and capture audio sounds.
• 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 doubleconversion 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
• 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. * Already installed with some versions.
• Pulls desired AF signals from noise. Outstanding S/N ratio is achieved, providing clean audio in SSB and AM.
• This automatically minimizes beat signals and heterodynes while preserving the receive signal. Also, the notch frequency is automatically adjusted to follow interfering beat signals— for example, reducing interference from RTTY signals during SSB operation.
• 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.
• The IC-718 has a low distrotion 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 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.
• 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 the adjustable break-in delay.
• A VOX (voice operated transmission) is included with the IC-718. It provides handsfree operation by detecting audio signals from the microphone. It’s easy!
• An optional IF filter can be installed into the transceiver to suit your operating preference.
• When the optional CR-338 HIGH STABILITY CRYSTAL UNIT is installed, you get a very high frequency stability of ±0.5 ppm.
• Either the AT-180 or AH-4 optional antenna tuner can be used with the IC-718 to suit your installing conditions, or operating style. Of course, the AH-4 control circuit is built into the IC-718.
• 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 convenient when changing operating bands.
• 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.
• A clear, electronically-generated voice announces operating frequency, mode and receiving signal strength level when the optional voice synthesizer unit, UT-102, is installed.
• USB, LSB, CW, RTTY (FSK) and AM modes are built-in
• Level adjustable noise blanker
• RF attenuator and Pre-amplifier
• Variety of scanning function types
• Total 101 memory channels are available
• Hand microphone is supplied, and more
