[SD-User] CW speed variations

[Richard W L Limebear]

Greetings

Has anyone experienced speed changes while SD is transmitting ?

The symptom, which occurred during the British AFS contest a couple of
weeks ago, showed up like this: 

SD sending an exchange at normal speed, suddenly slows down, speeds up,
slows down, speeds up etc. Speed was set at about 28wpm and dropped to
(guess) about 15wpm just like hitting the speed control on an el-bug whilst
sending. 

System: SD 9.84 in a maximised DOS window on a W98 laptop. Happened twice
during the 4-hour contest after, say, about 90 minutes of operating; didn't 
have time to go into diagnostics, just rebooted and restarted.
