Using an Icom 7800 with CAT commands that work properly. On startup, VarAC does not have the rig change to the proper passband filter. In this case, I have the CAT set to select passband filter #2. Once I either change the band or slot, the proper passband is selected.
I have attached the CAT section for the rig and the log. I activated debug mode for log collection.
Steps I took to reproduce the issue:
Passband is on filter 1
Open VarAC
Frequency display is correct but passband is not set properly
Change slot once, passband is then set properly
By default (unless you disabled it on settings), VarAC will move to the last working frequency and will initiate also the mode change (USB/USB-D)
If you disabled it then indeed it will happen only next time you change a band/slot.
BUT - If you want to do something upon startup/exit of VarAC - place parameters in these two parameter:
VarACStartCmd=
VarACExitCmd=
you can duplicate the USB-D command values into the VarACStartCmd and VarAC will run it upon startup.
73s!
