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

[Chris R. NW6V]

Richard, I went into this at length in my book, and in hours of sessions on
LICW. So, I don't want to try and cover all that here.

But, by "sideways" do you mean "flat" versus "position of function? " You
changed terminology.

Position of function refers to the angle of the wrist, controlled by the
position of the radius and ulna. It is the most relaxed position of the
arm,  and moves the motion generation muscles for "up/down motion" from the
wrist and forearm to the upper arm. It is WILDLY different from the flat
wrist, as shown in that army film (which speaks of being able to balance a
quarter on the back of your hand while sending). that's impossible in the
"position of function," with the wrist tilted roughly 60 degrees.

If you don't follow,  consider the difference in arm and hand position
position between shaking hands (position of function) and patting a dog on
the head (hand flat).
