Reliable long distance communications

General Details

Simple operation with keypad

A minimum of buttons and knobs provide uperior feature selectability. The 10 keypad allows you to enter an operating frequency or a memory channel number directly. VFO mode is available for continuous frequency operation.

General coverage receive

The IC-78 covers 0.03-29.999999MHz* in SSB, CW, RTTY and AM modes. The 1st receiver mixer provides superior receiver sensitivity, rejecting nearby interfering signals.

*Guaranteed range: 0.5–29.999999MHz

Front mounted loud speaker

With the speaker facing the operator, audio sounds can be clearly heard without impediment during operation.
