Morse code and interword gaps may be lengthened so the word rate is only 5 words per minute. Using different character and text speeds is, in fact, a common practice, and is used in the Farnsworth method of learning Morse code. Some methods of teaching Morse code use a dichotomic search table. Morse Code cannot be treated as a classical radioteletype (RTTY) signal when it comes to calculating a link margin or a link budget for the simple reason of it possessing variable length dots and dashes as well as variant timing between letters and words. For the purposes of Information Theory
Morse code for non-Latin alphabets Morse code for non-Latin alphabets This is a summary of the use of Morse code to represent alphabets other than Latin. The Greek Morse code alphabet is very similar to the Latin alphabet. It uses one extra letter for Greek letter "Χ" and does not use the codes for Latin letters "J", "U" and "V". The "tonos" is not transmitted in Morse code; the receiver can simply infer which vowels require one. The "Greek diphthongs" presented in the bottom three rows of the table are specified in old Greek Morse-code tables but they are never used in actual communication, the
