All SImVIm radio functions are intended to work independently from any aircraft model (as many other SimVim functions).
Of course if you make it as "hardware" (not looking at your virtual on-screen panel).
This software is developing to became eventually a "cockpit simulator", not just I/O interface, to build any cockpit without need to use specific aircraft model/developer (you only will need a good flight model, either freeware or not).
For example, you don't need a "zibo" mod , the default Laminar b737 is good for cockpit building, and zibo mostly has a few more "dummy" switches/annunciators.
Regarding specific FF questions - please use related topic (I will delete this one)
