Icom IC-78 handheld transceiver

Main functions of the transceiver:

• All main operating modes. Work with all) (USB, LSB, CW, RTTY, AM) types of modulation is possible.
• IC-78 has both the mode of a free set of the frequency (VFO), and an operating mode with in advance programmed channels.
• It is possible to install one additional filter on 455 KHZ with bandwidth in the transceiver from 250 to 3,3 KHZ.
• Simplicity and convenience of management. The minimum quantity of buttons with a possibility of their blocking. Each button has only one function, programming from the keyboard.
• Good cooling system. 100% a cycle and stable characteristics at any power provide a cast aluminum framework and the silent fan.
• Built-in system of voice-activated control by the transmitter (VOX), compression of a telephone signal.
• Magnificent quality of a sound provides a big loudspeaker on the forward panel.
• Adjustable rasstroyka on reception (RIT).
• Excellent characteristics of the receiver. The IC-78 receiver blocks the range of the frequencies of 500 KHZ - 30 MHz. The preamplifier (10 dB) and VCh an attenuator (20 dB) is provided.
• Scheme of suppression of pulse hindrances (NOISE BLANKER).
• The additional highly stable CR-338 generator provides stability of frequency +/-0,00005% in the range of temperatures of-30... +60 °C.
• 99 channels of memory with symbolical names to 8 symbols. Channel of a priority call (CALL).
• The computer interface (format CI-V), allows to operate practically all functions of the transceiver.
• For use the socket for connection of external modems is provided in systems of data transmission or with UBPCh terminals.
• The transceiver can be completed with shtyrevy and dipolar antennas, the external tuner, desktop microphones, external loudspeakers, the power supply unit and, if necessary, the converter of tension of a direct current of 24 V ® 12 Century.
