Just for clarification, I don't use the internal CW or RTTY decode functions. I just use CWT for accurate CW netting. Following that it is easy to make the often useful TX offset when calling in a simplex pile. CWT is a function I use all the time and that is why its degraded performance in 4.51 was immediately noticeable.
