Thanks again for your response to my questions. As I read your answers I see that the first question should read "WHEN" should I ask the other op to slow down, not "What is the proper way" etc etc....73 Gary
When? "As early as possible!"
Otherwise, you're wasting his time, and yours.
I have found "CWGet" software to be a very useful tool in dealing with people who send faster than I can read (which is almost everybody in a contest). It doesn't work with weak signals, or badly-formed code, but it's pretty good with "solid copy" CW.
