The 706 series consists of the three models 706, 706MKII and 706MKIIG. There are differences between them, see below.
IC-706 & IC-706MKII
Both models cover 0.03-200 MHz in CW/SSB/AM/NFM/WFM. The only difference is a sometimes built-in DSP unit and a higher output power on 2m.
The 'MKIIG is the latest radio of the 706 series. It comes with a built-in DSP unit and covers a frequency range of 0.03-200 and 400-470 MHz in CW/SSB/AM/NFM/WFM.
