The numbers are suspicious, (presumably) post-viterbi errors without UCB shouldn't happen, unless the driver isn't properly querying the demod stats. I'm not sure of the nxt2004's history so maybe this has always been an issue, maybe BER and UCB were never properly implemented? If I had a card I'd take a look. I don't so I can't help. Clearly, I wouldn't trust that driver or its numbers right now. - Steve
