I assumed folk would realize that the engine is the same in the two packages. I wanted to see if there was a difference between the Hyper Sensitive profile (which exists as a predefined profile only in WinWarbler) and the Standard profile which is the default in both packages. I was surprised after the tests to see the significant difference in performance made by inserting the notch filter between the mark and space frequencies. TrueTTY would seem to deserve wider attention. I have used UA9OV's CW Get for a number of years to zero beat my CW and perhaps I should keep a copy his TrueTTY running as a second receive modem when I work RTTY. Wes, WZ7I
