Hmmm,,, this is interesting... I guess I have always used mode A however, I
think I would like mode B as I have a nasty habit releasing the paddle too
soon and losing the last element.... I guess the Orion is also mode A...
Although I haven't used it much on CW yet, the little I did play with it, it
seemed the same as any other keyer although a bit smoother.....
thanks for the explanation....
