It's a page dedicated to explain how to make trainer cords to join different brands of radios. The same problems (finding PPM signal, changing polarity, ...) are found in this task.

MoFI, thanks for pointing out the IR option. How could I have missed it, I must be getting senile .

I am already figuring out the issues. So far I can use 2 resistors and IR emmiter/detector pair connected directly to the output of the trainer jack and get reasonable comms with my Ipaq and Axim Pocket PC's. All I have on hand are some high power IR emmiters and I think I need some generic IRDa capable ones (1 meter max). I am being careful not to overdrive the outputs as I'm guessing the microcontroller producing these signals is probably only capable of sourcing 20-40ma at most.

I'm having trouble converting the bytes as they seem to be inverted but I should have that figured out soon unless someone does first.

No wires would be awesome! IR should work great for shooting a new program into the radio. I'll add a send and confirm program function to the software to accomodate the IR comms.
