Perhaps if you are only talking about the CW decoder, but in general my experience with 4.51 is utterly dead opposite of yours. It *DOES* change a lot of sweet spots, but once adjusted for those, the improvement in all areas is rather extraordinary. Again, the sweet spots for a lot of things seemed to have moved, but given the changes in AGC, that's not really surprising. Using the second receiver in diversity, 4.51 improves signals near or at the AGC intercept, allowing a truer separation of those. We tested this thoroughly at Field Day, and all who used the K3 with 4.51 remarked on how good the diversity was.
Weak signal performance with 4.51 was clearly much better by ear if one was using an AGC with lower numbers in the settings. 73, Guy.
