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.

Samuel Finley Breese Morse Medal of geographical research.” The following people received the award in the year specified: Samuel Finley Breese Morse Medal The Samuel Finely Breese Morse Medal was established in 1902. Designed by Laura G. Fraser, this medal is awarded by the American Geographical Society for "achievements and pioneering in geographical research." Samuel Finley Breese Morse was a painter, but also a noted inventor. After extensive travel in Europe, Morse invented the first recording telegraph, which he submitted at patent for in 1837. His system of dots and dashes, equip with a dictionary and words, later was known as Morse Code. After his
