All right....in explicit detail....write down and/or take/post pictures of what you've got so far; transmitter schematic, receiver schematic, transmitter firmware (PBP), receiver firmware (PBP) and other relavent facts.

And unless I've missed it, all I see is the fact that you are probing your receiver output while you are sending repeat bytes into the transmitter. I don't see anything saying that a PIC is connected to the receiver itself... That is what I've been wanting to know all along. What is the receiving PIC doing about all these signals...not what your 'scope is doing about them...

'cause quite frankly, that PBP software posted earlier by me and the schematics from Rentron should work just fine and like I said, and even though the modules aren't rated for it, I can get them to work at 9,600 baud reliably (19,200 intermittently). And this is all on a solderless plug-in type breadboard, nothing special about the circuit. And it works out to a few hundred feet.

Unless you messed with the tuning adjustment on the receiver (like I did on one of my modules and it took me literally days to get it back into adjustment), then all bets are off...
