Common Letter-Groups in Morse Code

If you are using Google Chrome to view this page, it may be better to zoom out to "zoom 80%".



Ideally, "copy words not letters".
Actually, however, it is not easy to copy a long English word at a time particularly for non-native speakers of English. In particular, when type-copying or writing-down is needed, it is difficult to type or write down an entire word while head-copying the next word.
To deal with this, it is effective to copy a common letter-group in a word as one unit.

Example:
INTERRELATIONSHIP = INTER + RELA + TION + SHIP




You can change CW Speed, Effective Speed, CW Audio Frequency, etc., by clicking the rightmost setting icon in the CW Players.

(Default Settings: Speed: 20 WPM; eff.Speed: 20 WPM; Word space: off; Frequency: 750 Hz)

Regarding "Speed" (i.e., character speed) and "eff.Speed" (i.e., effective speed), please see https://lcwo.net/forum/78 and https://lcwo.net/forum/1592 .

For me, the object of this training is to obtain ARRL Code Proficiency Certificate at 40 WPM.
I believe that this page and the following three websites are very helpful to achieve this object as well as improve your head-copying and type-copying (with a keyboard) or handwriting-copying skills.

(Note: Although this practice is focused on word-based copying, I think that sentence- and context-based copying is also important. Of course, listening to actual CW QSOs on the air is far more important for practice for CW QSOs.)
