Thanks for the reply Vic.
Nearly all my operating is on CW rag chew. The microphone is only plugged in 
for the Radio Club SSB net. I have ten year's experience of CW operation and 
I would say that I am still learning.
I like to send at a speed that is close to the other guy's speed.
I like to send clearly with correct spacing and without too many mistakes so 
that the other guy can copy well.
At my present stage of learning CW I can comfortably send at 21 wpm on the K3 
speed control. I am referring to a rag chew that can last up to 30/45 
minutes. I do not know what overall speed I am sending at and it is not 
necessarily relavent to this discusion.  There are days when I can send well 
at 22 wpm on the K3 speed control and meet the above requirements to ensure 
that I am sending clearly and in a way that the other guy can copy well.
However, there are days when the K3 speed control of 22 wpm is too fast and 
days when the K3 speed control of 21 wpm is too slow.  On those days I would 
like to be be able to set the K3 speed control to 21.5 wpm. There is 
nothing "magic" about this :-)  perhaps one day I shall find the need for a 
K3 speed control of 22.5 wpm :-)
Perhaps the reason why I have this problem with the K3 speed control is 
because until I started using the K3 internal keyer I have always used the 
Logikeyer from Bob Locher.

I hope that I have described my situation adequately and that I have now 
clearly explained the reason for my request for a finer resolution on the K3 
keyer speed control knob.
