I was taught "American style" straight-key sending to lay my arm on the desk with and keep my wrist relaxed but straight. The whole forearm moves to operate the key with the bending taking place at the elbow.
In the merchant marine and Army radio schools, moving the wrist was considered the quickest way to get a "glass arm" that would cripple the individual and prevent further sending (I suspect the medics would call the problem it caused "carpal tunnel syndrome" today). Similarly, a bug (or keyer paddle, I suppose) was operated by rolling the forearm back and forth, not by pressing with the fingers. The fingers remained relaxed but fixed in position, the space between them whatever is comfortable to accommodate the finger pads as the hand and arm rolled back and forth to operate the dit or dah levers. Using those techniques, a good operator can send strings of messages for an hour or more at a time without taking a break or being fatigued. I'd never try that moving my wrist or fingers! Ham setups today tend to be different. In commercial CW it was suicide to have the key contacts spaced closely or the spring tension light. Often we were sending on a moving, vibrating ship, in a bouncing airplane or some other unstable surface. The solution was to open up the gap on the key and tighten the spring. Most keys were left that way. Modern hams seem to like very close spaced contacts that can be manipulated by a soft touch of the finger tips. That seems to work very well for them, but it's definitely a relatively *new* technique. The good side of the "old" system was that we could send consistently good CW even if the key was stiff with a heavy spring or if it had had worn pivots instead of precision bearings, or even if it lacked a single shiny chrome or polished brass part <G>.

I believe it was G.B Shaw who once said: "England and America are two countries separated by a common language." So, we can now add to that, "and by morse sending technique?" 73, Fred K6DGW - Northern California Contest Club - CU in the 2008 Cal QSO Party 4-5 Oct 08 - www.cqp.org _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
