Myself (ver 10.50) and K1GU (ver 10.49) experienced poorly generated CW during the CW SS. I had only one instance while Ned had several that seem to be random occurrences. I use LPT keying and Ned uses serial port keying. I wonder if there is something else that is causing the problem other than the Microham usb to serial interface. Chuck, KE4OAR
