To be more precise on "true Morse Sending";
Each dit is one element, each dah is three elements, intra-character spacing is one element, inter-character spacing is three elements and inter-word spacing is seven elements. The word PARIS is exactly 50 elements. Thus lets look at just 2 characters of Paris sent; Note that after each dit/dah of the letter P -- one element spacing is used except the last one. (Intra-Character). After the last dit of P is sent, 3 elements are added (Inter-Character). Thus: P di da da di 1 1 3 1 3 1 1 (3) = 14 elements A di da 1 1 3 (3) = 8 elements ETC until the last letter S is sent then After the word PARIS - 7 elements are used. Going thru the rest of the word Paris If you send PARIS 5 times in a minute (5WPM) you have sent 250 elements (using correct spacing). 250 elements into 60 seconds per minute = 240 milliseconds per element. 13 words-per-minute is one element every 92.31 milliseconds. The Farnsworth method sends the dits and dahs and intra-character spacing at a higher speed, then increasing the inter-character and inter-word spacing to slow the sending speed down to the overall speed. For example, to send at 5 wpm with 13 wpm characters in Farnsworth method, the dits and intra-character spacing would be 92.3 milliseconds, the dah would be 276.9 milliseconds, the inter-character spacing would be 1.443 seconds and inter-word spacing would be 3.367 seconds.

I was thinking the standard way was the 13 to 15 wpm : sending with long 5 wpm spacing. you forget that the spacing between the dits+dahs are also governed by the same speed/rhythm. therefore...sending faster sounds requires faster silence-gaps...therefore everything at 12wpm which is not 5wpm. to be 5wpm, the sounds and the gaps must be at the same speed or it aint 5wpm. by all means learn morse with faster characters with longer gaps...but only so that the training allows the gaps to be shortened. true morse has all elements sent at the same rhythm (even the silent bits) |
