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 words per minute (WPM) or characters per minute, while fixed-length data
forms of telecommunication transmission are usually measured in baud or bps.
Originally created for Samuel F. B. 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adapt to automated circuits, so for most electronic communication it has been replaced
by machine readable formats, such as Baudot code and ASCII. - Wikipedia

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
