I found out something interesting. I have XP on my PC at home and AFP works fine with my JR transmitters. I also have a laptop running XP and AFP sees the interface but not the JR transmitter. That's right....not any JR transmitter! But guess what? It works fine with a Futaba! I'm going to put a scope on it at work and look at the voltage levels to see what's going on. My guess is that maybe IPACS needs to redesign their interface to make it JR/laptop friendly! Then they should put this info on the web and replace interfaces as required.

***UPDATE*** My Airtronics Vanguard TX works too. Same plug that works with Futaba.
