|The Straight Key
The Vertical or Straight key is indeed the simpler (mechanically speaking) of all CW devices.
This key must be literally "played" like an instrument.
In this video, former RT Officer Oscar Portoghese I7OHP, shows how to correctly manipulate a straight key.
In transmiting CW, timing and spacing is crucial. The basic unit of measure of CW is the dot, all other elements are based on it.
The correct use of a Straight key is a fundamental prerequisite for learning CW, relatively few people are able to jump directly to the bug or a paddle.
Always keep in mind CW motto : "Accuracy trascends speed" !
