 From a file here called basicprogram.txt which apparently  
acccompanied the program:
K9EUI RTTY program version 7.8

"When talking about speeds (WPM) or baud rates, we usually round the
numbers off to the nearest whole unit. Actual speeds/bauds normally
enountered are as follows:


UNIT CODE   WPM      BAUDS         USE
7.42        60       45.45         OLD BELL, MILITARY, AMATEUR
7.0         65       45.45         OLD WESTERN UNION
7.5         66       50            ITU EUROPEAN STANDARD
7.42        67       50            U.S. - ALLIED MILITARY
7.0         71       50            OLD EUROPEAN CCIT STANDARD
7.42        75       56.88         OLD BELL SYSTEM
7.0         95       66.67         U.S. MILITARY
7.42        100      74.2          U.S. STANDARD / BELL SYSTEM
7.0         106      74.2          LIMITED MILITARY
7.0         107      75            U.S. NAVAL
7.          140      100           MOSTLY WEATHER STATIONS


One point in bringing this up is that many newer RTTY units and
programs give 75 baud as one of the standard speeds. This is not
really true - what they really are set for is 74.2 baud but everyone
calls it 75."

I suspect something is wrong. I'd not expect the Dovetron to drift any  
noticeable amount.
