I have an IC-7300. The factory stock CI-V address is 94. Because I have to operate with some MARS programs that do not recognize the existence of new equipment, I have had to change my address to that of an IC-7100 which is 88. I can use Omni rig, though I would rather not have that extra layer. So I simply found the file VarAC_cat_commands.ini and the section for the 7300 commands and changed each instance of 94 in the command strings to 88. Now it works perfect with just the CAT controls.
[It is only a text file and it can be changed.]
