Traditional ratio between Dits and Dahs was always 1 : 3 One of my radio's internal keyers default is 1:2.8, and adjustable in the range of 1 1:2.5 through 1:4.5. What is the rationale for using other than 1:3 ? Do higher code speeds "flow" better with shorter DAHs ? Anything wrong with the 1:2.8 default ? Been licensed a good while, but I am still novice at CW ! Love to hear from those with more experience in these matters.
