I don't think it would be that hard. I suspect that you might need to write a nasal script to handle it and in that script you would manipulate the properties for the radio as the control was manipulated. There are some joystick XML files that have nasal script in them to do other types of things so you should be able to find some examples that will at least give you some clues about how to go about it. It is easy to change various properties inside a nasal script. Also I think there are likely others here that would be able to point you toward examples that are a closer fit to what you want to do. > > > Also you might want to have a look at: > > > > http://www.simkits.com/ > > > > They have USB driven instruments and if you ask them they will send you > > interface documentation.
