IC-718
HF ALL BAND TRANSCEIVER
THE ORIGIN OF THE
HF TRANSCEIVER
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 dvnamic 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 prqctical 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 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 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
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 receive quality in your shack,
vehicle or during DX' pedi-tion.
Noise reduction:
Pulls desired AF signals from noise. Outstanding S/N ratio is achieved, providing
clean audio in SSB, AM and FM.
Automatic Notch filter:
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.
VOX operation
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!
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 optional antenna tuner unit, AT-180 or AH-4 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. Simple
