I can't speak for the Orion's dsp, but my audio dsp does better noise reduction and better CW S/N when it has more input bandwidth, rather than narrow. This I suspect comes from narrow band noise being more correlated than wider band noise which makes the algorithm for noise rejection work better with the wider band noise. 73, Jerry, K0CQ -- Entire content copyright Dr. Gerald N.
