And one other point I might make...
The 432-433Mhz modules seems to work, the 315 doesn't.
Why not use 2 432-433Mhz modules, one master, one slave. Sure you can't use them both at the same time, bidirectionally. But for instance, maybe the slave will ONLY answer after the master has spoken. Use a PICs pin to provide power to the modules, turn off the master's receiver while it's transmitting, turn off the transmitter while it's receiving, and so on with the slave, only the other way around in reverse...
I think I get what the end result is supposed to be, with changing all the bits around and sending the modified code back. But why not let the PIC handle the bit changing after receiving a certain code or something along those lines.

OK. You're crazy!
