The interface cannot interject spaces and pauses into the CW, it is just a
transistor switch, turned on and off by the computer port. The interfaces I
use are all designed and built by myself. They work fine for DxBase, Writelog,
N1MM, CTWin, CTDos, and various other programs. I ran CTWin for SS CW using a
P4 3GHz laptop running XP. Nothing else was running, except Icom radio
control. The CW was not smooth. There were pauses in the CW, no dits or dots
were missing, just timing was erratic, which is consistent with running under
windows. RF was also not a factor as the erratic timing can be reproduced
without actually transmitting. I also run CW at 30 to 34wpm, which makes
timing more critical.
