[CW] W6BNB Bob Shrader's method of using a straight key.

[Richard Knoppow]

    You have confused me about the sideways grip. No photo on your post, 
would like to see it.
    I will point out that the strongest movement of the hand is in the 
direction of wrist moving the fingers toward the forearm, regardless of 
the position of the hand. The sideways motion is relatively weak. It is 
NOT the motion used for a bug or sideswiper, those use the same motion 
as a straight key but with the key lever turned 90 degrees so that the 
whole hand is also turned. The motion used to work those keys is the 
same as is used for a straight key. In effect, a sideswiper is a 
straight key with a second set of contacts.
     I am familiar with the Caitlin grip, as descirbed in old books on 
the telegraph. It seems to me to the same grip as described in much 
later books on telegraphy, for instance, the U.S. Army manuals. I.e. 
index finger pressing the knob with thumb and ring finger at the sides 
of the knob. Is this a wrong understanding? Show me a picture please.
     Also, the European grip, using keys with large knobs or handles and 
the elbow in mid air, seems to me to use essentially the same motion as 
the grip for the American style knob and the elbow on the table as a 
fulcrum.
