Everyone, I want to thank you all for your help and suggestions. After working off and on, I now have a working wireless link! I'm sending single bytes across the length of the house. Now, I can move on to the next layer of the network stack. As suggested here and in different forum links, I greatly increased the length of the preamble being sent and also increased the data rate. I choose to continue using Roman Black's encoding method since I was already familiar with it and had a transmitter that I'd verified its output on the oscope. I did ditch the receiver module that generated the oscope shots I'd sent earlier, and I'm using another generic module (RXB6) which has a noisy output when there's no signal; but the long preamble does take care of getting the AGC to adjust down. I really want to thank you all. I'm only a guy with too many hobbies, but I've learned a lot over the years from the professionals on this list. Take care.
