I wish to use VarAC on HF with an Icom IC-728. This is possible by using OmniRig. However I want to use the CAT-commands. I took the command set for IC-707 and changed the HEX-code from 3E to 38 on all places. When I try it out it is possible to change frequency on the radio from within the Settings window, choosing the different TEST frequencies the radio switches to that. However it seems impossible to change frequency from the main VarAC window. Does anyone have a working set of cat-commands for IC-728.
PS. I have another IC-728 that is is modified to HEX-code 3E and 9600 baud. Using this one all works well with changing frequencies when I choose CAT IC-707.
