Hi Randy
Nice! I purchased a similar 'tactical' handset as a -still ongoing mini- project. The G106 is one of a few HF-radio's that support a speaker? & mic via the front connector (?). So it should work easily.
I rewired the handheld as in the schematic I draw (incl PTT). See the images below.? You can be creative and add a compressor module in the handset. Still have to test it though... In theory it should work!
BTW: in the schematic 'geel' means Yellow, 'zwart' means Black, 'wit'means White and 'rood' means Red. ;-)
kind regards
