Hello, Have you tried with just raw data?. I mean, use a file with data you already know, for example in a file, make the proper modulation, send it over the air, receive the data, put it into a file, compare both files.
I can guess that the problem is in the decoder in the receiver part. Study about how to handle errors in digital communications. I found this project on the web, they explain how the receiver send packets to the transmitter to inform about the integrity of the info in the packets received.
