For those of you who were interested in NOISE REDUCTION 
algorithms, I believe you will find the answer here in
part 3 of Doug's well crafted and thorough QEX articles

Ken, thanks very much for the links. Based on some other data I have seen, the link you highlighted 
-----> http://www.doug-smith.net/kf6dx3.pdf <-------

is a very good description (First 4 pages - pages 13,14,15 and 16) of the NR algorithm used (An Adaptive Predictor with Leaky LMS Algorithm) in the V1 Orion code and in the early releases of the V2 Code (I don't know about later releases of the V2 Code).

Actually, you can find many of the Orion V1 Firmware design concepts in the four part QEX article you referenced (Also in Doug Smith's book published by the ARRL - "Digital Signal Processing Technology). 
Thanks again,
