Morse code modulator (CW): each written character is sent as dots and dashes of a tone with the timing of the alphabet (International: dot 1, dash 3, element space 1, letter space 3, word space 7 units). A space (or a character which is not in the alphabet) is a word space. The tone is switched on and off with a raised cosine ramp of MorseConfig::ramp_ms.
