Programmer Question....
What is the frequency of the signal on the trainer-cable? i'm sure it's not in the megahertz as it is once it's modulated onto the FM carrier...it's gotta be less.
If it's under 20 kHz, you could potentially adapt an ordinary soundcard to speak trainer-cable and you're all set - either direction (as well as have PC control plane, you could have radio joysticks control flight-simulator) It takes software only to do this or at very most some minor electronics to adapt the signal strength / impedence
I'm a capable programmer, but i'd need to know everything about the trainer cable's encoding, and someone to help me with the adaptor cable electronics. Anyone?
