[CW] High speed sending...

Mike,

How do you count three activities for a single lever paddle and four for a 
dual lever paddle? You are missing a very important event on the single 
lever paddle that must be counted. See below:

   A  push dot, release dot, push dash, release dash (4)       dot, release 
dot, dash, release dash (4)

If you don't release the pressure from the thumb which is applied to the 
single lever paddle to create the dot, your thumb and your finger will be 
working against each other when you go to create the dash.

Jan Ditzian, KX2A, pointed this out to you back on Tuesday, May 2, 2000, in 
a message to you on the TenTec reflector.

When counting the activities to create the letter A with a SINGLE LEVER 
paddle, why are you NOT counting the release of the dot as an activity? (It 
surely must be done in order to move the paddle over to the dash side.)

When you use a dual lever paddle with an iambic keyer you must release the 
dot before you create the dash or else you will send the letter R. Your 
example above for a dual lever paddle/iambic keyer is incorrect, but I will 
overlook it, since I know you are aware of what I just explained about 
releasing the dot before creating the dash.

  I'm really interested in reading your answer to my question.
