You might try using ListenRaw to see the whole byte stream and look at the checksums. I forget if the basestation code verifies the checksum. I know the Listen code rejects messages that fail the checksum, so it looks like you are getting "good" messages. Maybe try a longer, predictable, data packet too. It's suspicious that only the data packet is corrupted and not the header...
