Hi Chris, please, keep the walls intact and your brain operable.
Hm, I've not looked too deeply into this, but: 2 Samples per symbol means that your bandwidth should be at least samplerate/2, and you've in fact got excess bandwidth. What does the frequency sink on transmitter side say? On the receiving side, you filter to samplerate/3, which is less! Then, this has no framing, so its impossible for the receiver to know whether something it received is the first bit in a byte! Still a bit peculiar that you're still getting valid ASCII, no doubt.
