IC-706MK2G
HF/VHF/UHF ALL MODE
TRANSCEIVER

 

HF to 70 cm band coverage
Operating frequency range is covering all amateur frequency bands, fom 1.8 to 430 MHz. All mode (SSB, CW, FM, AM, RTTY) is possible and full 100W output power is available on HF and 6m bands, 50W on VHF and 20W for 70cm band operation.

High stability transmitter
MOS-FET power amplifiers are emplyed at the PA unit for all HF, 6m, 2m and 70cm bands. A one-piece die-cast aluminum chassis with large cooling fan is employed. This combination provides stable, high quality output with low IMD and low spurious emissions even during full duty cycle and extended operation.

Illuminated keys and switches
Backlighting of keys and switches is a great help during nighttime operation - the intensity is adjustable.

Tone squelch standard
Tone squelch operation is available in FM mode for basic signalling and quiet standby. Tone frequencies can be set independently for tone squelch (RX/TX) and repeater tones. A tone scan function is available to search for repeater's access tone.

Automatic repeater function
An automatic repeater function is available and repeater frequencies can be programmed via a special operation.

Simple operation
The individual band change key, a sub dial and quick band change capability provide simple operation. The individual band change key allows quick and easy QSY, the sub dial enhances mobile and memory operation, and the quick band change capability selects pre-set frequency bands with the last-used frequency and mode. Each band can store preamplifier/attenuator and tuner on/off settings.

Simple band scope function
This function sweeps ± 14 steps from the displayed frequency and plots received signal strength on the function display. This function is useful not only for checking HF band conditions, but also seeking vacant frequencies during VHF or UHF operation.

DSP Features
DSP capabilities are available. These include noise reduction and auto notch functions.

Compact with detachable panel
The IC-706MK2G is very compact at 167(W)x58(H)x200(D)mm and weights 2.5 kg, making it ideal for mobile and remote places operation. A detachable front panel allows easy installation in your shack or in a wide variety of mobile applications.

Optional high frequency stability
±5ppm of high frequency stability is provided when an optional CR-282 HIGH STABILITY CRYSTAL UNIT is installed.

Narrow FM capability
For FM operation on the 10m or the 2m (where narrow FM is required) bands, the IC-706MK2G has narrow FM capability that allows you to take advantage of this operating mode.

107 memory channels with alphanumeric name display
99 channels can memorize both transmit and receive frequencies separately; 6 channels are for programmed scan edges; and 2 channels are for CALL memory on 2m and 70cm bands. Up to 9 characters alphanumeric names can be programmed into each memory channel.
