Definitely can happen from overdriven AFSK. I have seen it on my own spots when I had a soundcard driver problem. The windows mixer showed normal audio levels but the actual output was 100%.

Interesting! How would you generate two separate sets of mark and space frequencies with different spacing but the same call.  Is this a possible outcome from overdriven AFSK?

I don't think they should be showing up as busts in the CT1BOH algorithm, but as QSYs.

I'm taking the liberty of copying the RTTY contesting reflector on this
- I think someone there probably has the answer
