AN IMPORTANT USE for Morse Code is signalling for help through SOS, “· · · — — — · · ·”. This can be sent many ways: keying a radio on and off, flashing a mirror, toggling a flashlight and similar methods.
Some mobile telephones have an alert sound for incoming SMS which reads “SMS” in morse code,
“· · · — — · · ·”.
It may surprise you that in speed contests between expert Morse code operators and expert cell phone SMS text messaging users, Morse code has consistently won.

A Little About Morse Code
Morse code is a type of character encoding that transmits telegraphic information using rhythm. Morse code uses a standardized sequence of short and long elements to represent the letters, numerals, punctuation and special characters of a given message. The short and long elements can be formed by sounds, marks, or pulses, in on off keying and are commonly known as “dots” and “dashes” or “dits” and “dahs”. The speed of Morse code is measured in wpm or cpm, while fixed-length data forms of telecommunication transmission are usually measured in baud or bps.
Originally created for Samuel Finley Breese Morse’s electric telegraph in the early 1840s, Morse code was also extensively used for early radio communication beginning in the 1890s. For the first half of the twentieth century, the majority of high-speed international communication was conducted in Morse code, using telegraph lines, undersea cables, and radio circuits. However, the variable length of the Morse characters made it hard to adapt to automated circuits, so for most electronic communication it has been replaced by machine readable formats, such as Baudot code and ASCII.
The most popular current use of Morse code is by amateur radio operators, although it is no longer a requirement for amateur licensing in many countries. In the professional field, pilots and air traffic controllers are usually familiar with Morse code and require a basic understanding. Navigational aids in the field of aviation, such as VORs and NDBs, constantly transmit their identity in Morse code. Morse code is designed to be read by humans without a decoding device, making it useful for sending automated digital data in voice channels. For emergency signalling, Morse code can be sent by way of improvised sources that can be easily “keyed” on and off, making Morse code extremely versatile.
