IC-78 HF Transceiver

Reliable straight forward HF communications

Durable, powerful construction
The IC-78 delivers a powerful 100 W of output power, providing the talk power you need to reach the most distant locations. Its one-piece, die-cast aluminum construction combined with a large heat sink, helps keep internal temperatures down and ensures that operation is stable at high duty cycles. And its compact size of 240(W) × 95(H) × 239(D) mm* makes installation easy. * 97/16(W) × 33/4(H) × 913/32(D) in.

Simple operation
The IC-78 is equipped with a large easy-to-read LCD. A minimum number of switches and controls allow for superior feature selectability. Keys access functions directly - there's no secondary function key. You can enter your operating frequency*, or memory channel number directly from the 10-key pad. * depending on version

Ample 99 channels with 8-digit channel name capability
An affordable 99 duplex memory channels are available for storing individual transmit and receive frequencies, operating mode, filter setting, as well as 8-character channel names. You can enter channel assignments easily from the 10-key pad. In addition, an extra 1 call memory is available for storing the most often used, or most important frequency. An independent, one-touch recall switch is available.

Superior basic performance
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.
