[CW] Fast Morse Recording

[pa0wv]

I remember from a booklet, (Seinen en Opnemen) written for future hams 
back in the fiftees in Dutch language, which published also official 
requirements for commercial telegraphists,  for first class examination 
hand sent with a straight key 25 wpm plain text was required  and 20 wpm 
for code groups. David Ring explained recently that the dit speed 
actually was the same for words PARIS (plain text at 25 wpm) and CODEX 
(code groups at 20 five chars random groups per minute). So the dit 
speed (shortest time interval of space between the elements of a 
character, was 16,6 dits per second = baud rate for code and also for 
plain text. That is because PARIS takes 50 dits in 60 second for 1 wpm.

Now you present a few samples, and I measure the speed of a sample of 
text presented, by counting the number of dits during the time the 
sample used.

First sample : = arriverai gare nord minuit =

10.93 s and 256 dits, that is 28 wpm

Obvious hand sending, due to irregular speed. I took a fast part of the 
whole sample.

Second complete sample:: ation acceptyour proposal abrasion slabber 
pannel propose commending with galte

tooks 35,98 s contains 734 dits so 24.48 wpm. Failure for the speed test 
of first class commercial telegraphist!

Do I make a calculation error? I hope so.
