Oh, two more clues that might help you, Dennis.
1. I just noticed that in my situation the keyer does not track linerally. That is to say that the ratio of the dots to the dashes changes pretty dramatically with a change in speed. If I set it up to sound pretty good at 20 wpm, it will sound much worse at 40.
2. Also, the speed that reads on the screen is not close to actual speed. At a reading of 60 WPM, it is really sending 28 WPM. Showing 55 = 27 actual, 50=26, 45=25, 40=23, 35=21, 30=18, 25=16, 20=13, 15=11 etc. The slower the speed the nearer the screen speed is to actual.
Hopes this helps.
Thanks again.
