  #!/usr/bin/python """ Morse Code Generator. Geoff Robinson, G4AKW, Version 1.0, 4th December 2011. Requirements: Python 2.7, Linux OS, alsaaudio. Usage # python mainmorse.py The basic element of Morse code is the dot and all other elements can be defined in terms of multiples of the dot length. The word PARIS is used because this is the length of a typical word in English plain text, it has a total length of 50 dot lengths. If the word PARIS is sent ten times in a minute using normal Morse code timing then the code speed is 10 WPM. There are 500 dot lengths in a minute for 10 wpm or 1000 dot lengths per min for 20 wpm. The dot length is therefore 60mS for 20 wpm. The python dictionary 'code' and the function convert() converts characters to their dot space equivalents i.e either on or off keying.
