IC-718 description :

The ICOM IC718 has 0.03~30 MHz general coverage receive capability. A 4-element system is employed for the 1° 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 IC-718 is also 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.
