Internally RadioHead and VirtualWire uses a 4to6 bit en-/de-coding. Their reasoning is that if your payload is either high or low for too long, "for a good DC balance". have you experianced anything related to this? You but in 0b01 padding before each byte, maybe this is enough. Your solution is substantially lower overhead.

Thank you for your feedback. I agree with you that it has lower overhead. I also have really great results in terms of range (200 meters through walls and buildings) and data rate compared to VirtualWire!
