In fact, trained operators can recognize each other because of this, much like we can often recognize who is speaking on the phone just by hearing their voice. Every operator’s style, or “fist”, has subtle variations in the timings of the dots, dashes, and the pauses between these elements, the letters, and the words. In an earlier era of Morse code decoders, one tough part was dealing with the idiosyncrasies of each sender. We would like to see this hooked up to a proper Morse code key, and see how fast could drive it before it conks out. Simplicity comes at a price - changing the speed requires changing constants in the code. This is probably the simplest decoder possible, and thus its logic is pretty straightforward to follow. Wrote a simple Morse Code decoder to run on his Arduino and display the text on an LCD shield.
