IC-706 series :

The ICOM's base model IC-706, first introduced in 1995, was upgraded with the IC-706 MK II (IC-706 Mark 2) model two years later. The MK II added more features and more power, with up to 20 Watt on 144 MHz band and the DSP module as optional equipment. The latest version IC-706 MK IIG (IC-706 Mark 2G) adds other features and capabilities as the 440 MHz band for a complete HF/VHF/UHF transceiver.

IC-706 MK II optional IF filter :

ICOM IC-706MK-II optional IF filter:
After filter installation, specify the installed filter (FL-100/101/103/223/232) using initial set mode. These filters can be installed in either direction.
