The data stream from the transmitter is encoded by swinging the frequency up (or down) a little to mark the separation and pulse lengths of each servo.
Which way the swing is, is whether its positive or negaitive shift.
If yoyu use a transmitter/receiver pair on opposite shifts, they simply don't work.
Isn't it true that Aerotronics and JR use positive and all the others use negative shift? I found this out when I tried a JR flight pack with my Futaba Xmitter. It didn't work and Tower had to send me a HiTech unit instead.
I never needed to find out, because here on 35Mhz, they all have the same shift.
I think Multiplex also uses postive shift. There are several aftermarket receivers that will work on either.
