This open-source application presents a list of editable phrases, then plays the selected phrase as morse code (or Hellschriber) through the sound output. The audible tones produced may be used directly if a modulated signal is desired, but the sound can also be routed through an easy-to-build radio interface which converts this sound into on/off keying for the transmitter. See http://code.google.com/p/androidomatic-keyer for details.
