MB-63 Mounting Bracket
OPC-581 Separation Kit
MB-62 Mobile Mounting Bracket

The radio performs well, transmits slightly under power by 2 to 5 watts, depending on the band.

The IC-706MKIIG carries on the '706' series tradition of base station performance and features in a mobile rig-sized package. Building on this legacy, frequency coverage is expanded to the 70 cm band and output power is increased for the 2 m band. A long list of enhancements, both to usability and performance, as well as added features and functions have produced the latest in the evolution of the '706' series.

HF to 70 cm band coverage

Operating frequency range has been expanded to the 70 cm band. Of course, all mode operation (SSB, CW, RTTY, AM and FM) is possible and a full 100W of output power is available for HF and 6m operation; 50W for 2m and 20W for 70cm operation.

output powerHigh stability transmitter

MOS-FET power amplifiers are employed at the PA unit for all HF, 6m, 2m and 70cm bands. And, a one piece aluminum, diecast chassis with a 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 even 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 (Tx/Rx) and repeater tones, and a range of 50 frequencies is available. A tone scan function is available to search for a repeater's access tone quickly and easily.

UT-106DSP features

DSP capabilities are available*. These include noise reduction and auto notch functions. Superior receive quality in your shack, vehicle or during DX'peditions.
*AF DSP; UT-106 DSP UNIT required for some versions.

Compact with detachable panel*1

The IC-706MKIIG is very compact at 167(W) × 58(H) × 200(D) mm*2 and weighs a mere 2.5kg*3, making it ideal for DX'peditions, etc. A detachable front panel allows easy installation in your shack or in a wide variety of mobile applications.
*1 An optional separation cable is required;
*2 69/16(W)×29/32(H)×77/8(D) in;
*3 5.5 lb.

Automatic repeater function*

An automatic repeater function is available and repeater frequencies can be programmed via a special operation. This eliminates the need for repeater settings for 6m, 2m or 70cm repeater operation.
*Standard for USA version; programming required for others.

Optional high frequency stability

±0.5 ppm of high frequency stability is provided when an optional CR-282 HIGH STABILITY CRYSTAL UNIT is installed.

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. Also, each band can store preamplifier/attenuator and tuner on/off settings.

band scopeSimple 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 FM operation.

Narrow FM capability

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

107 memory channels with alphanumeric name capability

99 channels can memorize both transmit and receive frequencies separately; 6channels are for programmed scan edges; and 2 channels are for call memory for the 2m and 70cm bands. And, up to 9-character alphanumeric names can be programmed into each memory channel.
